500 AM CDT TUE MAY 4 2010

THIS HAZARDOUS WEATHER OUTLOOK COVERS NORTHERN...WESTERN...
CENTRAL...AND SOUTHERN OKLAHOMA...AND WESTERN NORTH TEXAS.

.DAY ONE...TODAY AND TONIGHT...

THUNDERSTORM OUTLOOK...
THUNDERSTORMS ARE NOT EXPECTED THROUGH TONIGHT.

DISCUSSION...
SOUTH TO SOUTHWEST WINDS WILL INCREASE TODAY... AHEAD OF A COLD
FRONT THAT WILL MOVE SOUTHEAST ACROSS NORTHERN AND WESTERN OKLAHOMA
LATE TONIGHT. LOW-LEVEL MOISTURE WILL REMAIN LIMITED... AND
CONDITIONS WILL REMAIN TOO STABLE TO SUPPORT THUNDERSTORMS.

PROBABILITY TABLE...
VALID THROUGH 700 AM CDT WEDNESDAY MAY 5.
PROBABILITY OF THUNDERSTORMS OCCURRING IN THE
NWS NORMAN COUNTY WARNING AREA... LESS THAN 10 PERCENT.

OTHER HAZARDOUS WEATHER...
NONE.

.DAYS TWO THROUGH SEVEN...WEDNESDAY THROUGH MONDAY...

THUNDERSTORM OUTLOOK...
THE COLD FRONT WILL STALL SOUTH OF THE AREA ON WEDNESDAY... THEN
LIFT NORTH INTO KANSAS BY LATE THURSDAY BEFORE MOVING SOUTH ACROSS
THE AREA AGAIN THURSDAY NIGHT. WARM AIR ALOFT WILL ACT AS A CAP AND
WILL LIKELY PREVENT THUNDERSTORM DEVELOPMENT OVER THE AREA THROUGH
THURSDAY. BY THURSDAY NIGHT... INCREASING LOW-LEVEL MOISTURE AHEAD
OF THE COLD FRONT MAY CONTRIBUTE TO THE DEVELOPMENT OF A FEW
THUNDERSTORMS OVER NORTH CENTRAL OKLAHOMA WHERE THE CAP WILL BE
SLIGHTLY WEAKER.

THUNDERSTORM CHANCES WILL INCREASE ACROSS THE AREA SATURDAY NIGHT
AND SUNDAY... IN RESPONSE TO A MORE SUSTAINED RETURN FLOW OF MOIST
AIR FROM THE GULF OF MEXICO INTO THE SOUTHERN PLAINS. THE CHANCE OF
THUNDERSTORMS WILL PERSIST INTO MONDAY... MAINLY OVER NORTHERN AND
EASTERN OKLAHOMA. THERE ARE SOME INDICATIONS OF A POTENTIALLY
SIGNIFICANT INCREASE IN THE RISK OF SEVERE WEATHER NEXT MONDAY.

OTHER HAZARDOUS WEATHER...
NONE.

THE NEXT SCHEDULED HAZARDOUS WEATHER OUTLOOK WILL BE ISSUED AT NOON
TODAY.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NORMAN OK
348 PM CDT TUE MAY 4 2010

.DISCUSSION...
ONLY MADE A FEW CHANGES TO THE EXISTING FORECAST THIS TIME AROUND.
THE MAIN CHANGES WERE TO UPDATE THE TEMPERATURE FORECAST FOR
THURSDAY... WHICH SHOULD BE QUITE HOT IN OUR SOUTHWEST COUNTIES.
DOWN-SLOPE FLOW... COMBINED WITH VERY WARM TEMPERATURES ALOFT...
WILL LIKELY RESULT IN AFTERNOON TEMPERATURES NEAR 100 DEGREES F
IN KNOX COUNTY TEXAS. SIMILARLY HIGH TEMPERATURES WILL COVER MOST
OF OUR WESTERN COUNTIES... AND WARMER-THAN-TYPICAL READINGS ARE
EXPECTED ACROSS THE REST OF OUR FORECAST AREA.

RAISED POPS A BIT FOR SUNDAY AND SUNDAY NIGHT. ISENTROPIC LIFT
AND VERY MOIST AIR ARE EXPECTED SATURDAY NIGHT THROUGH SUNDAY
NIGHT OVER MUCH OF OUR AREA. INITIALLY... THE PRECIPITATION SHOULD
BE MOSTLY RAIN OR RAIN SHOWERS... THEN THUNDERSTORMS WILL JOIN IN
ON SUNDAY.

THE REAL FUN LOOKS LIKE IT WILL BEGIN ON MONDAY... AS A DRYLINE
AND ASSORTED OTHER INGREDIENTS SET UP ALONG THE WESTERN EDGE OF
OUR AREA. SEVERE WEATHER REMAINS A DISTINCT POSSIBILITY MONDAY
EVENING ACROSS OUR WESTERN COUNTIES. IN FACT... ALMOST ANY DAY
NEXT WEEK LOOKS AT LEAST SOMEWHAT FAVORABLE FOR SIGNIFICANT... IF
NOT SEVERE... WEATHER.

.AVIATION...
GUSTY SOUTH WINDS WILL DECREASE THIS EVENING BEFORE SHIFTING TO THE
NORTH OVERNIGHT AS A COLD FRONT MOVES SOUTH AND SOUTHEAST ACROSS
OKLAHOMA INTO TEXAS. NOT MUCH IN THE WAY OF CLOUD COVER EXPECTED
WITH FRONTAL PASSAGE... COULD BE A NARROW BAND OF STRATOCU JUST
BEHIND THE FRONT DEVELOP ACROSS CENTRAL SECTIONS... BUT SHOULD HAVE
MINIMAL IMPACT. GUSTY NORTH WINDS WILL ACCOMPANY THE FRONT... BUT
SHOULD DECREASE DURING MID AFTERNOON HOURS AS SFC HIGH BUILDS INTO

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NORMAN OK
418 AM CDT WED MAY 5 2010

.DISCUSSION...
THE OUN CWA WILL BE ON A TEMPERATURE ROLLER COASTER RIDE THROUGH
FRIDAY. A COLD FRONT NOW LOCATED FROM AROUND ELK CITY TO CHEROKEE
WILL CONTINUE INTO NORTH TEXAS THIS AFTERNOON...EVENTUALLY WEAKENING
AS IT PROGRESSES. HIGH TEMPERATURES AROUND 5-10 DEGREES COOLER
THAN THOSE MEASURED YESTERDAY WILL BE COMMON...EXCEPT IN THE
SOUTHEAST CORNER OF THE CWA WHERE TEMPERATURES WILL BE SIMILAR OR
EVEN SLIGHTLY WARMER THAN TUESDAY VALUES. THE BOUNDARY WILL HEAD
BACK TO THE NORTH ON THURSDAY AS A SURFACE LOW DEVELOPS ON THE
HIGH PLAINS IN RESPONSE TO A SHORT WAVE TROUGH TRACKING ACROSS THE
NORTHERN ROCKIES AND INTO THE NORTHERN/CENTRAL PLAINS...WITH
TEMPERATURES NEAR 100 DEGREES POSSIBLE IN SOUTHWESTERN PORTIONS OF
THE CWA. ON FRIDAY...A STRONGER COLD FRONT THAN THE ONE ARRIVING
TODAY WILL PUSH ACROSS THE CWA.

MEAGER MOISTURE...AS WELL AS SYNOPTIC SCALE FORCING REMAINING WELL
TO OUR NORTH...SHOULD KEEP RAIN OUT OF THE CWA ON FRIDAY DESPITE
THE ARRIVAL OF A COLD FRONT. SATURDAY WILL REMAIN ON THE COOL SIDE
BEFORE WARM ADVECTION BEGINS FROM SATURDAY NIGHT INTO SUNDAY. RAIN
FORCED BY ISENTROPIC LIFT IN A FAIRLY STABLE MOIST LAYER WILL BE
POSSIBLE...WITH THE BEST CHANCE BEING IN NORTHEASTERN PORTIONS OF
THE CWA.

MED RANGE MODELS SHOW SOME DISAGREEMENT BY MONDAY. FOR THE LAST
SEVERAL RUNS...DEVELOPMENT OF A LONGWAVE TROUGH IN THE WESTERN US
HAS BEEN SUGGESTED EARLY NEXT WEEK. A WARM FRONT MAY LINGER IN THE
VICINITY ON MONDAY...WITH THE ASSOCIATED WARM ADVECTION LEADING TO
THE RETENTION OF LOW POPS. A DRYLINE IS EXPECTED TO SET UP BY
MONDAY...AND THE ECMWF HAS BEEN FAIRLY CONSISTENT IN BRINGING THE
BASE OF A SHORT WAVE TROUGH JUST NORTHWEST OF THE CWA.
CERTAINLY...ACCORDING TO PRESENT MODEL SOLUTIONS...ANY STORMS
INITIATING ON THE DRYLINE MONDAY AFTERNOON/EVENING WOULD STAND AN
EXCELLENT CHANCE OF BECOMING SEVERE. FOLLOWING MONDAY...MUCH
UNCERTAINTY EXISTS WITH THE PLACEMENT OF KEY WEATHER FEATURES.
HOWEVER...IT DOES LOOK LIKE ACTIVE WEATHER CAN BE EXPECTED INTO AT
LEAST THE MIDDLE OF NEXT WEEK.

AREA FORECAST DISCUSSION

343 PM CDT WED MAY 5 2010

.DISCUSSION...
RATHER DRY AIR IS IN PLACE BEHIND COLD FRONT WITH EXCEPTION OF
SOUTH CENTRAL AND SOUTHEAST OKLAHOMA. WINDS WILL DECREASE AND
SHIFT TO THE EAST AND SOUTHEAST OVERNIGHT AS WAVE MOVES ACROSS THE
NORTHERN ROCKIES. MORE HUMID AIR WILL RETURN TO WESTERN AND
NORTHERN OKLAHOMA AS WARM FRONT LIFTS NORTH LATE TONIGHT INTO
THURSDAY. NEXT COLD FRONT NOT EXPECTED TO ENTER FAR NORTHWEST
OKLAHOMA UNTIL THURSDAY EVENING...SO VERY WARM TO HOT CONDITIONS
EXPECTED ALL AREAS THURSDAY AFTERNOON.

COLD FRONT WILL PUSH QUICKLY SOUTH THURSDAY NIGHT INTO EARLY FRIDAY
MORNING WITH GUSTY POST-FRONTAL WINDS AT/OVER 40 MPH. STILL APPEARS
THAT CONVECTION CHANCES WILL BE SLIM WITH STRONG CAP AND BETTER
FORCING NORTH OF FA.

RATHER COLD TEMPERATURES ARE EXPECTED MOST AREAS SATURDAY MORNING
IN THE WAKE OF THE FRONT. GFS/NAM...FORECAST AN INCREASE IN MID
LEVEL CLOUDS EARLY SATURDAY WITH SLOWER RETURN OF CLOUD COVER PER
EC MODEL. WAA AT 7H MAY ALSO RESULT IN WIDELY SCATTERED CONVECTION
DURING DAY SATURDAY IF GFS/NAM TIMING IS MORE CORRECT. WILL SIDE
ON THE COOLER SIDE SATURDAY WITH COOL/DRY AIRMASS IN PLACE AT THE
SURFACE. BETTER CHANCE FOR STORMS WITH RETURN MOISTURE AND
INCREASING FLOW WILL START SATURDAY NIGHT INTO SUNDAY.

POSITION OF LONG WAVE TROUGH AND SURFACE FEATURES BY MONDAY MAY
BRING A ROUND OR TWO OF SEVERE WEATHER TO THE FORECAST AREA MONDAY
INTO TUESDAY.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NORMAN OK
416 AM CDT THU MAY 6 2010

.DISCUSSION...
SURFACE LOW PRESSURE WILL INTENSIFY OVER EASTERN COLORADO TODAY...
THEN MOVE SOUTHEAST INTO OKLAHOMA TONIGHT. SOUTH WINDS AHEAD OF
THE LOW WILL BRING WARMER AND MORE HUMID AIR INTO OKLAHOMA AND
NORTH TEXAS. TEMPERATURES WILL REACH CLOSE TO 100 DEGREES F THIS
AFTERNOON IN THE SOUTHWEST CORNER OF OUR FORECAST AREA - IN KNOX
COUNTY TEXAS.

AS THE LOW MOVES ACROSS THE SOUTHERN PLAINS... IT WILL BE
ACCOMPANIED BY A COLD FRONT... AND FRIDAY WILL BE SIGNIFICANTLY
COOLER. STRONG WINDS WILL FOLLOW THE FRONT... BUT THE WINDS SHOULD
BE BELOW WIND ADVISORY CRITERIA... EXCEPT POSSIBLY IN NORTHWEST
OKLAHOMA EARLY FRIDAY MORNING. WE WILL NOT ISSUE A SECOND/THIRD-
PERIOD ADVISORY FOR SUCH A MARGINAL SITUATION... AND WILL LET
LATER SHIFTS MONITOR TRENDS AND DETERMINE THE NEED FOR AN
ADVISORY. BY SATURDAY MORNING... LOW TEMPERATURES WILL BE CLOSE TO
FREEZING OVER OUR FAR NORTHWEST COUNTIES. WINDS WILL PROBABLY
PREVENT A FROST.

MOISTURE WILL BEGIN TO RETURN SATURDAY NIGHT... AND RATHER STRONG
ISENTROPIC LIFT WILL SUPPORT INCREASING RAIN CHANCES INTO SUNDAY.
THERE IS STILL SOME UNCERTAINTY REGARDING THE AMOUNT OF MOISTURE
AND LIFT... SO HAVE LEFT POPS IN THE CHANCE CATEGORY FOR NOW.

MODEL DIFFERENCES CONTINUE FOR MONDAY... BUT THEY CONTINUE TO SHOW
A CLASSIC SEVERE WEATHER SETUP... FOR SOME PART OF THE CENTRAL AND
SOUTHERN PLAINS. FOR OKLAHOMA AND NORTH TEXAS... IT APPEARS THAT A
STRONG CAP WILL SUPPRESS CONVECTION OVER MOST OF THIS AREA UNTIL
EVENING. FROM MONDAY EVENING INTO THE OVERNIGHT PERIOD... IT LOOKS
LIKE ANY STORMS THAT FORM WITHIN OUR FORECAST AREA WILL HAVE A
STRONG POTENTIAL FOR BECOMING SEVERE.

AFTER MONDAY... UNCERTAINTY INCREASES... BECAUSE THE WEATHER ON
EACH DAY WILL DEPEND TO A SIGNIFICANT DEGREE ON WHAT HAPPENS ON
THE PREVIOUS DAY. IN GENERAL TERMS... HOWEVER... WEDNESDAY LOOKS
LIKE ANOTHER POSSIBLE STORM DAY... AND THERE IS AT LEAST A
POTENTIAL FOR HEAVY RAINFALL FOR THE LAST HALF OF NEXT WEEK.

A CAPPING LAYER OF WARM AIR ALOFT WILL LIKELY PREVENT THUNDERSTORM
DEVELOPMENT OVER THE AREA.

PROBABILITY TABLE...
VALID THROUGH 700 AM CDT FRIDAY MAY 7.
PROBABILITY OF THUNDERSTORMS OCCURRING IN THE
NWS NORMAN COUNTY WARNING AREA... LESS THAN 10 PERCENT.

OTHER HAZARDOUS WEATHER...
STRONG NORTH WINDS WILL OCCUR BEHIND THE COLD FRONT LATE TONIGHT AS
IT MOVES THROUGH NORTHERN AND WESTERN OKLAHOMA. SUSTAINED WINDS OR
FREQUENT GUSTS IN EXCESS OF 30 MPH WILL BE POSSIBLE.

.DAYS TWO THROUGH SEVEN...FRIDAY THROUGH WEDNESDAY...

THUNDERSTORM OUTLOOK...
THUNDERSTORM CHANCES WILL INCREASE ACROSS THE AREA AS EARLY AS
SATURDAY NIGHT... IN RESPONSE TO A RETURN FLOW OF MOIST AIR FROM THE
GULF OF MEXICO INTO THE SOUTHERN PLAINS.

A POTENTIALLY SIGNIFICANT SEVERE WEATHER EVENT STILL APPEARS
POSSIBLE IN OR NEAR THE SOUTHERN PLAINS EARLY NEXT WEEK. AT THIS
TIME THE DETAILS ARE STILL RELATIVELY UNCERTAIN DUE TO THE LONG LEAD
TIME... BUT THE CHANGE IN THE LARGE-SCALE WEATHER PATTERN CONTINUES
TO SUGGEST THE POSSIBILITY OF A REGIONAL SEVERE WEATHER OUTBREAK IN
THE CENTRAL OR SOUTHERN PLAINS AROUND MONDAY OR MONDAY NIGHT.
ANOTHER ROUND OF STRONG TO POSSIBLY SEVERE THUNDERSTORMS WILL BE
POSSIBLE BY AROUND WEDNESDAY.

EMERGENCY MANAGERS... STORM SPOTTER GROUPS... AND RELATED
AGENCIES... AS WELL AS THE GENERAL PUBLIC... ARE ENCOURAGED TO PAY
CLOSE ATTENTION TO THE LATEST FORECAST INFORMATION THROUGH THE
UPCOMING WEEKEND AND INTO THE FIRST HALF OF NEXT WEEK.

OTHER HAZARDOUS WEATHER...
NONE.

WINDS WILL INCREASE TODAY AS LOW PRESSURE INTENSIFIES OVER EASTERN

AN HOUR OR TWO... BUT FOR THE MOST PART THE TIMING IS TOO
DIFFICULT TO INCLUDE IN THE TAFS AT THIS POINT. A NARROW BAND OF
MVFR-LEVEL CLOUDS MAY FOLLOW THE FRONT ACROSS NORTHERN OK.

SURFACE LOW PRESSURE WILL INTENSIFY OVER EASTERN COLORADO TODAY...
THEN MOVE SOUTHEAST INTO OKLAHOMA TONIGHT. SOUTH WINDS AHEAD OF
THE LOW WILL BRING WARMER AND MORE HUMID AIR INTO OKLAHOMA AND
NORTH TEXAS. TEMPERATURES WILL REACH CLOSE TO 100 DEGREES F THIS
AFTERNOON IN THE SOUTHWEST CORNER OF OUR FORECAST AREA - IN KNOX
COUNTY TEXAS.

AS THE LOW MOVES ACROSS THE SOUTHERN PLAINS... IT WILL BE
ACCOMPANIED BY A COLD FRONT... AND FRIDAY WILL BE SIGNIFICANTLY
COOLER. STRONG WINDS WILL FOLLOW THE FRONT... BUT THE WINDS SHOULD
BE BELOW WIND ADVISORY CRITERIA... EXCEPT POSSIBLY IN NORTHWEST
OKLAHOMA EARLY FRIDAY MORNING. WE WILL NOT ISSUE A SECOND/THIRD-
PERIOD ADVISORY FOR SUCH A MARGINAL SITUATION... AND WILL LET
LATER SHIFTS MONITOR TRENDS AND DETERMINE THE NEED FOR AN
ADVISORY. BY SATURDAY MORNING... LOW TEMPERATURES WILL BE CLOSE TO
FREEZING OVER OUR FAR NORTHWEST COUNTIES. WINDS WILL PROBABLY
PREVENT A FROST.

MOISTURE WILL BEGIN TO RETURN SATURDAY NIGHT... AND RATHER STRONG
ISENTROPIC LIFT WILL SUPPORT INCREASING RAIN CHANCES INTO SUNDAY.
THERE IS STILL SOME UNCERTAINTY REGARDING THE AMOUNT OF MOISTURE
AND LIFT... SO HAVE LEFT POPS IN THE CHANCE CATEGORY FOR NOW.

MODEL DIFFERENCES CONTINUE FOR MONDAY... BUT THEY CONTINUE TO SHOW
A CLASSIC SEVERE WEATHER SETUP... FOR SOME PART OF THE CENTRAL AND
SOUTHERN PLAINS. FOR OKLAHOMA AND NORTH TEXAS... IT APPEARS THAT A
STRONG CAP WILL SUPPRESS CONVECTION OVER MOST OF THIS AREA UNTIL
EVENING. FROM MONDAY EVENING INTO THE OVERNIGHT PERIOD... IT LOOKS
LIKE ANY STORMS THAT FORM WITHIN OUR FORECAST AREA WILL HAVE A
STRONG POTENTIAL FOR BECOMING SEVERE.

AFTER MONDAY... UNCERTAINTY INCREASES... BECAUSE THE WEATHER ON
EACH DAY WILL DEPEND TO A SIGNIFICANT DEGREE ON WHAT HAPPENS ON
THE PREVIOUS DAY. IN GENERAL TERMS... HOWEVER... WEDNESDAY LOOKS
LIKE ANOTHER POSSIBLE STORM DAY... AND THERE IS AT LEAST A
POTENTIAL FOR HEAVY RAINFALL FOR THE LAST HALF OF NEXT WEEK.

851 PM CDT THU MAY 6 2010

.UPDATE...WARM AND BREEZY SOUTHERLY WINDS WILL PERSIST UNTIL
OVERTAKEN BY A STRONG PACIFIC COLD FRONT...AND GUSTY NORTH WINDS
ARRIVING FROM THE NORTHWEST. AN UPPER TROUGH ASSOCIATED WITH THE
FRONTAL PASSAGE...DESPITE BEING DEEP AND COLD ACROSS THE NORTHERN
PLAINS...WAS RELATIVELY LOW IN AMPLITUDE. THIS PLACES A STRAIGHT
JET WITH STRONG AGEOSTROPHIC CIRCULATION JUST TO THE NORTH OF OUR
FORECAST AREA. SUBSIDING AIR POLEWARD OF THE JET AXIS SHOULD
MAINTAIN THE CAP OVER OUR FORECAST AREA...EVEN IN THE FACE OF THE
STRONG FRONTAL PASSAGE. THE WEATHER SHOULD REMAIN DRY...WITH WINDS
BEING THE MAIN FORECAST ISSUE.

THE THERMAL CHANGE ACROSS THIS FRONT IS VERY IMPRESSIVE...WITH A
20 DEGREE CELSIUS GRADIENT AT 850 MB...ACROSS OUR FORECAST
AREA...PREDICTED BY FRIDAY MORNING. INTENSE COLD ADVECTION WILL
COUPLE WITH INCREASED VERTICAL MIXING DURING THE MID MORNING TO
EARLY AFTERNOON HOURS FRIDAY TO THE WEST AND SOUTHWEST OF OKLAHOMA
CITY...AFFECTING MUCH OF SOUTHWEST OKLAHOMA AND WESTERN NORTH
TEXAS. THE STRONGEST WIND GUST MAY NOT PERSIST MORE THAN ONE OR
TWO HOURS AT ANY GIVEN LOCATION...BUT WE WILL HAVE TO WATCH THIS
CAREFULLY. A SHORT FUSE WIND ADVISORY MAY BECOME NECESSARY.
UNIQUELY SITED OBSERVATIONS SUCH AS THE MEDICINE PARK MESONET MAY
EVEN SEE GUSTS OVER 50 MPH.

ALSO...GIVEN THE STRENGTH OF THE COLD FRONT AND THE LACK OF A
DOWNSLOPE WIND COMPONENT...WE ADJUSTED THE FRIDAY HIGH
TEMPERATURES JUST A COUPLE OF DEGREES COOLER...GOING CLOSER TO THE

THIS HAZARDOUS WEATHER OUTLOOK COVERS NORTHERN...WESTERN...
CENTRAL...AND SOUTHERN OKLAHOMA...AND WESTERN NORTH TEXAS.

.DAY ONE...REST OF TONIGHT...

THUNDERSTORM OUTLOOK...
THUNDERSTORMS ARE NOT EXPECTED THROUGH TONIGHT.

DISCUSSION...
LOW PRESSURE WILL TRACK NEAR THE NORTHERN OKLAHOMA BORDER
OVERNIGHT...DRAGGING A STRONG PACIFIC COLD FRONT INTO THE REGION
BEGINNING IN THE NORTHWEST. ALTHOUGH A MODEST AMOUNT OF GULF
MOISTURE HAD RETURNED TO THE REGION AHEAD OF THIS FRONT...UPPER
LEVELS REMAINED UNFAVORABLE FOR THUNDERSTORM DEVELOPMENT...AND THE
AIR IS EXPECTED TO REMAIN CAPPED.

PROBABILITY TABLE...
VALID THROUGH 700 AM CDT FRIDAY MAY 7.
PROBABILITY OF THUNDERSTORMS OCCURRING IN THE
NWS NORMAN COUNTY WARNING AREA...LESS THAN 10 PERCENT.

OTHER HAZARDOUS WEATHER...
STRONG NORTH WINDS WILL OCCUR BEHIND THE COLD FRONT LATE TONIGHT AS

IT MOVES THROUGH NORTHERN AND WESTERN OKLAHOMA. SUSTAINED WINDS OVER
25 MPH...WITH FREQUENT GUSTS IN EXCESS OF 35 MPH ARE EXPECTED.

.DAYS TWO THROUGH SEVEN...FRIDAY THROUGH WEDNESDAY...

THUNDERSTORM OUTLOOK...
THE FRONT ARRIVING EARLY FRIDAY WILL REMOVE MOISTURE AND INSTABILITY
FROM THE SOUTHERN PLAINS THROUGH SATURDAY. THEN...DURING THE TIME
FROM SATURDAY NIGHT THROUGH SUNDAY NIGHT...WARM AND HUMID AIR WILL
MOVE BACK NORTHWARD IN ADVANCE OF A TROUGH DEVELOPING OVER THE
WESTERN STATES. THUNDERSTORMS MAY FORM IN PARTS OF OKLAHOMA AND
WESTERN NORTH TEXAS DURING THAT TIME...WITH ONLY A LOW POTENTIAL FOR
SEVERE WEATHER.

OUR CURRENT FOCUS...HOWEVER...IS MONDAY...WHEN A SMALL BUT WELL
DEFINED UPPER LEVEL DISTURBANCE WILL EJECT FROM THE LARGER TROUGH
OVER THE WESTERN STATES. IF THIS DISTURBANCE EJECTS WITH THE TIMING
AND STRUCTURE THAT ARE CURRENTLY FORECAST...IT WOULD BE CAPABLE OF
PRODUCING A SIGNIFICANT SEVERE WEATHER EVENT FROM MONDAY AFTERNOON
INTO MONDAY NIGHT. INFORMATION ABOUT THE GREATEST RISK AREAS AND
POTENTIAL IMPACTS...WILL BECOME BETTER DEFINED OVER THE WEEKEND.
THIS EVENT APPEARS...HOWEVER...TO SIGNAL A CHANGE IN THE LARGE SCALE
WEATHER PATTERN...WHICH COULD LEAD TO AN ACTIVE PERIOD BEGINNING
WITH THE SEVERE WEATHER ANTICIPATED ON MONDAY. ANOTHER ROUND OF
STRONG TO SEVERE THUNDERSTORMS AND HEAVY RAINFALL...WILL BE POSSIBLE
AROUND WEDNESDAY.

1105 PM CDT THU MAY 6 2010

.AVIATION...
GIVEN CURRENT PROGRESSION OF THE FRONT...HAVE SPED UP THE TIMING A
BIT OVERNIGHT. SHARP WIND SHIFT EXPECTED WITH STRONG NORTHERLY WINDS
INTO TOMORROW AFTERNOON. BAND OF STRATOCU LOOKS PROBABLE ACROSS
MAINLY NORTHERN AND CENTRAL SECTIONS OF OKLAHOMA LATE TONIGHT AND
TOMORROW MORNING AND WILL INCLUDE TEMPO MVFR CEILINGS FOR THIS.
DURATION/EXTEND OF LOW CLOUDS LESS CERTAIN ACROSS FAR SW OK/WRN N TX
SO WILL LEAVE OUT OF TAFS.


&&

.UPDATE...WARM AND BREEZY SOUTHERLY WINDS WILL PERSIST UNTIL
OVERTAKEN BY A STRONG PACIFIC COLD FRONT...AND GUSTY NORTH WINDS
ARRIVING FROM THE NORTHWEST. AN UPPER TROUGH ASSOCIATED WITH THE
FRONTAL PASSAGE...DESPITE BEING DEEP AND COLD ACROSS THE NORTHERN
PLAINS...WAS RELATIVELY LOW IN AMPLITUDE. THIS PLACES A STRAIGHT
JET WITH STRONG AGEOSTROPHIC CIRCULATION JUST TO THE NORTH OF OUR
FORECAST AREA. SUBSIDING AIR POLEWARD OF THE JET AXIS SHOULD
MAINTAIN THE CAP OVER OUR FORECAST AREA...EVEN IN THE FACE OF THE
STRONG FRONTAL PASSAGE. THE WEATHER SHOULD REMAIN DRY...WITH WINDS
BEING THE MAIN FORECAST ISSUE.

THE THERMAL CHANGE ACROSS THIS FRONT IS VERY IMPRESSIVE...WITH A
20 DEGREE CELSIUS GRADIENT AT 850 MB...ACROSS OUR FORECAST
AREA...PREDICTED BY FRIDAY MORNING. INTENSE COLD ADVECTION WILL
COUPLE WITH INCREASED VERTICAL MIXING DURING THE MID MORNING TO
EARLY AFTERNOON HOURS FRIDAY TO THE WEST AND SOUTHWEST OF OKLAHOMA
CITY...AFFECTING MUCH OF SOUTHWEST OKLAHOMA AND WESTERN NORTH
TEXAS. THE STRONGEST WIND GUST MAY NOT PERSIST MORE THAN ONE OR
TWO HOURS AT ANY GIVEN LOCATION...BUT WE WILL HAVE TO WATCH THIS
CAREFULLY. A SHORT FUSE WIND ADVISORY MAY BECOME NECESSARY.
UNIQUELY SITED OBSERVATIONS SUCH AS THE MEDICINE PARK MESONET MAY
EVEN SEE GUSTS OVER 50 MPH.

ALSO...GIVEN THE STRENGTH OF THE COLD FRONT AND THE LACK OF A
DOWNSLOPE WIND COMPONENT...WE ADJUSTED THE FRIDAY HIGH
TEMPERATURES JUST A COUPLE OF DEGREES COOLER...GOING CLOSER TO THE
NAM 2 METER TEMPS.

DEVELOPMENT. COOL WEATHER EXPECTED TONIGHT AND SATURDAY NIGHT WITH
LOWS IN THE 30S IN PARTS OF NORTHWEST OK SAT MORNING. RAIN CHANCES
RETURN BY SATURDAY NIGHT AS ELEVATED MOISTURE RETURNS ABOVE COOL
SURFACE RIDGE. RAIN CHANCES INCREASE AS WAA PATTERN STRENGTHENS
SUNDAY AND SUNDAY NIGHT IN ADVANCE OF UPPER TROUGH ADVANCING
EASTWARD THROUGH THE SOUTHERN ROCKIES. MODELS REMAIN CONSISTENT WITH
POTENTIAL SEVERE WEATHER EVENT ON MONDAY/MONDAY NIGHT AS S/W TROUGH

.DISCUSSION...
A COOL NIGHT IS IN STORE ACROSS THE CWA AS A SURFACE HIGH SETTLES
SOUTHWARD. ENOUGH OF A PRESSURE GRADIENT SHOULD BE PRESENT TO KEEP
NORTH WINDS IN THE 5-15 MPH RANGE MOST OF THE NIGHT. TEMPERATURES
MAY DROP TO NEAR FREEZING IN PROTECTED AREAS OF FAR NORTHWEST
OK...BUT PERSISTENT LIGHT WIND SHOULD KEEP TEMPERATURES FROM
FALLING TOO MUCH BELOW 38-40 DEGREES IN MOST AREAS. DURATION OF
TIME NEAR FREEZING IS EXPECTED TO BE SHORT. THEREFORE...WE WILL
PASS ON ISSUING A FROST ADVISORY.

COOL TEMPERATURES FOR EARLY/MID MAY WILL LAST THROUGH THE WEEKEND
IN MOST AREAS OF THE CWA. RAIN IS NOT EXPECTED UNTIL LATE SATURDAY
NIGHT INTO SUNDAY WHEN NORTHWARD MOVING MOISTURE IS LIFTED OVER
THE SURFACE HIGH. MODEL SOUNDINGS HAVE CONSISTENTLY SHOWN THE LIFT
TO BE THROUGH A RELATIVELY STABLE MOIST LAYER...AND WE HAVE KEPT
THUNDER IN THE ISOLATED CATEGORY UNTIL LATE ON SUNDAY.

VERY WARM AND MOIST AIR WILL MAKE A COMEBACK ON MONDAY...
HELPING TO CREATE CONDITIONS FAVORABLE FOR SEVERE STORMS. A
DRYLINE IS EXPECTED TO FORM SOMEWHERE IN THE VICINITY OF THE
EASTERN TX PANHANDLE AND WESTERN OK. A S/W TROUGH MOVING ACROSS
THE SOUTHWESTERN US AND THEN BRUSHING THE CWA TO THE NORTHWEST IS
EXPECTED TO PROVIDE SOME EXTRA LIFT IN AN VERY UNSTABLE
ENVIRONMENT WITH HIGH VALUES OF BOTH LOW LEVEL AND DEEP LAYER
SHEAR. DETAILS DEPEND HEAVILY ON THE TIMING OF THE TROUGH AS A
STRONG CAP WILL BE IN PLACE OVER THE LOW LEVEL MOISTURE...BUT THIS
SITUATION CONTINUES TO MERIT CLOSE ATTENTION.

FOR THE EXTENDED...MED RANGE MODELS ARE LEANING TOWARD A FRONTAL
BOUNDARY BEING LOCATED SOMEWHAT FARTHER NORTH THAN HINTED AT IN
PAST DAYS. THE LATEST HPC GUIDANCE HAS BEEN LOADED FOR TEMPS TO
FOLLOW THAT TREND. OTHERWISE...LOW END POPS EACH DAY LOOK GOOD

THIS HAZARDOUS WEATHER OUTLOOK COVERS NORTHERN...WESTERN...
CENTRAL...AND SOUTHERN OKLAHOMA...AND WESTERN NORTH TEXAS.

.DAY ONE...REST OF TONIGHT...

THUNDERSTORM OUTLOOK...
THUNDERSTORMS ARE NOT EXPECTED THROUGH TONIGHT.

DISCUSSION...
COOLER AND VERY DRY AIR HAD OVERSPREAD THE PLAINS. HIGH PRESSURE
WILL BUILD OUT OF THE ROCKIES...TOWARD OKLAHOMA AND NORTH TEXAS
OVERNIGHT...KEEPING THE WEATHER DRY.

PROBABILITY TABLE...
VALID THROUGH 700 AM CDT SATURDAY MAY 8.
PROBABILITY OF THUNDERSTORMS OCCURRING IN THE
NWS NORMAN COUNTY WARNING AREA...ZERO PERCENT.

OTHER HAZARDOUS WEATHER...
AS THE CENTER OF HIGH PRESSURE BUILDS INTO NORTHWEST OKLAHOMA LATE
TONIGHT...WINDS MAY BECOME LIGHT ENOUGH TO ALLOW TEMPERATURES TO
APPROACH FREEZING IN ISOLATED LOCATIONS. PATCHY FROST IS POSSIBLE
FOR A SHORT TIME AROUND SUNRISE...AND PEOPLE WATCHING OVER
PARTICULARLY SENSITIVE VEGETATION MAY WISH TO TAKE PRECAUTIONS.

.DAYS TWO THROUGH SEVEN...SATURDAY THROUGH THURSDAY...

THUNDERSTORM OUTLOOK...
GULF MOISTURE WILL BEGIN TO RETURN NORTHWARD BY SATURDAY NIGHT...
AT A FEW THOUSAND FEET ABOVE THE GROUND. THIS MOIST LAYER WILL GAIN
DEPTH BY SUNDAY AND MONDAY...FIRST RESULTING IN AN INCREASING CHANCE
OF THUNDERSTORMS...AND THEN AN INCREASING CHANCE OF STRONG
THUNDERSTORMS. THROUGH SUNDAY NIGHT...THE THREAT OF SEVERE STORMS
WILL BE LOW...BUT A FEW COULD PRODUCE MARGINALLY SEVERE HAIL AND
LOCALLY HEAVY RAIN BEGINNING SUNDAY AFTERNOON.

THE WEATHER ON MONDAY IS OF GREATER CONCERN. A SMALL BUT WELL
DEFINED UPPER LEVEL DISTURBANCE WILL EJECT FROM THE SOUTHERN
ROCKIES...PRODUCING A DEEP SURFACE LOW THAT WILL LIKELY TRACK ACROSS
KANSAS. THE LOW WILL DRAG A DRYLINE INTO OKLAHOMA AND WESTERN NORTH
TEXAS...MOST LIKELY BY EARLY AFTERNOON. BY THAT TIME...RICH GULF
MOISTURE WILL BE TRANSPORTED INTO THE REGION AHEAD OF THE DRYLINE.
ALTHOUGH A CAP WILL DEVELOP...LIFTING ALONG THE DRYLINE SHOULD BE
SUFFICIENT TO PRODUCE THUNDERSTORMS MONDAY AFTERNOON AND EVENING.
INSTABILITY AND WIND SHEAR ARE FORECAST TO BE MORE THAN ADEQUATE FOR
SUPERCELL STORMS...SOME OF WHICH MAY BE DAMAGING. INFORMATION ABOUT
THE GREATEST RISK AREAS AND POTENTIAL IMPACTS...WILL BECOME BETTER
DEFINED OVER THE WEEKEND. AS IT APPEARS NOW...HOWEVER...THIS EVENT
WARRANTS CLOSE ATTENTION.

THE WEATHER SYSTEM ARRIVING MONDAY WILL LEAVE A FRONTAL BOUNDARY
STALLED SOMEWHERE ACROSS THE SOUTHERN PLAINS. ON WEDNESDAY AND
THURSDAY...ADDITIONAL UPPER LEVEL DISTURBANCES WILL INTERACT WITH
THE FRONT...MAINTAINING A CHANCE OF SEVERE STORMS...AND AN
INCREASING CHANCE OF HEAVY RAINFALL.

OTHER HAZARDOUS WEATHER...
NONE.

THE NEXT SCHEDULED HAZARDOUS WEATHER OUTLOOK WILL BE ISSUED BY 5 AM
SATURDAY MAY 8.

THUNDERSTORMS ARE NOT EXPECTED THROUGH TONIGHT.

DISCUSSION...
A COOLER AND VERY DRY AIRMASS WILL REMAIN IN PLACE DURING THE DAY
TODAY. MOISTURE WILL BEGIN TO RETURN NORTH OVERNIGHT TONIGHT...
WHICH MAY RESULT IN RAIN SHOWERS DEVELOPING ACROSS THE AREA. AS
INSTABILITY WILL REMAIN VERY LIMITED THROUGH TONIGHT... NO
THUNDERSTORMS ARE ANTICIPATED.

PROBABILITY TABLE...

PROBABILITY OF THUNDERSTORMS OCCURRING IN THE
NWS NORMAN COUNTY WARNING AREA...10 PERCENT.

OTHER HAZARDOUS WEATHER...
NONE.

.DAYS TWO THROUGH SEVEN...SUNDAY THROUGH FRIDAY...

THUNDERSTORM OUTLOOK...
GULF MOISTURE WILL CONTINUE TO DEEPEN SUNDAY AND MONDAY...FIRST
RESULTING IN AN INCREASING CHANCE OF THUNDERSTORMS...AND THEN AN
INCREASING CHANCE OF STRONG THUNDERSTORMS. THROUGH SUNDAY
NIGHT...THE THREAT OF SEVERE STORMS WILL BE LOW...BUT A FEW COULD
PRODUCE MARGINALLY SEVERE HAIL AND LOCALLY HEAVY RAIN BEGINNING
SUNDAY AFTERNOON.

THE WEATHER ON MONDAY IS OF GREATER CONCERN. A SMALL BUT WELL
DEFINED UPPER LEVEL DISTURBANCE WILL EJECT FROM THE SOUTHERN
ROCKIES...PRODUCING A DEEP SURFACE LOW THAT WILL LIKELY TRACK ACROSS
KANSAS. THE LOW WILL DRAG A DRYLINE INTO OKLAHOMA AND WESTERN NORTH
TEXAS...MOST LIKELY BY EARLY AFTERNOON. BY THAT TIME...RICH GULF
MOISTURE WILL BE TRANSPORTED INTO THE REGION AHEAD OF THE DRYLINE.
ALTHOUGH A CAP WILL DEVELOP...LIFTING ALONG THE DRYLINE SHOULD BE
SUFFICIENT TO PRODUCE THUNDERSTORMS MONDAY AFTERNOON AND EVENING.
INSTABILITY AND WIND SHEAR ARE FORECAST TO BE MORE THAN ADEQUATE FOR
SUPERCELL STORMS...SOME OF WHICH MAY BE DAMAGING. INFORMATION ABOUT
THE GREATEST RISK AREAS AND POTENTIAL IMPACTS...WILL BECOME BETTER
DEFINED OVER THE WEEKEND. AS IT APPEARS NOW...HOWEVER...THIS EVENT
WARRANTS CLOSE ATTENTION.

THE WEATHER SYSTEM ARRIVING MONDAY WILL LEAVE A FRONTAL BOUNDARY
STALLED SOMEWHERE ACROSS THE SOUTHERN PLAINS. ON WEDNESDAY AND
THURSDAY...ADDITIONAL UPPER LEVEL DISTURBANCES WILL INTERACT WITH

146 PM CDT SAT MAY 8 2010

.DISCUSSION...
COOL AND RELATIVELY DRY AIR WILL REMAIN NEAR THE SURFACE INTO
SUNDAY BUT MOISTURE ABOVE THAT LAYER WILL QUICKLY INVADE THE DRIER
AIR MASS ALOFT TONIGHT. SATURATION IS EXPECTED IN NORTH TEXAS AND
JUST NORTH OF THE RED RIVER SUFFICIENT FOR LIGHT RAIN LATER
TONIGHT. LOW LEVEL CLOUDS ARE ALSO EXPECTED AS THE LOWER LAYERS
BEGIN TO MOISTEN EARLY SUNDAY. SUNDAY WILL BE CLOUDY AND
SEASONABLY COOL WITH SHOWERS POSSIBLE THROUGHOUT THE DAY. THE
APPROACH OF THE UPPER SYSTEM MONDAY WILL BRING A DRY LINE INTO
WESTERN OKLAHOMA MONDAY AFTERNOON. SUFFICIENT MOISTURE AND THERMAL
PROFILES ARE EXPECTED TO PRODUCE SEVERE THUNDERSTORMS MONDAY
AFTERNOON AND EVENING. THE COLD FRONT ASSOCIATED IS EXPECTED TO
STALL IN OKLAHOMA AND PROVIDE FOCUS FOR A CHANCE OF RAIN AGAIN
WEDNESDAY WHEN ANOTHER UPPER LEVEL STORM APPROACHES FROM THE
SOUTHWEST. SOUTHWEST FLOW ALOFT AND THE STALLED FRONT WILL KEEP
RAIN CHANCES IN THE REST OF THE WEEK. AS NO MAJOR PATTERN CHANGE
IS EXPECTED, THE HUMID AIR MASS AND CHANCE FOR RAIN COULD EXTEND
INTO THE WEEKEND.

...HEIGHTENED THREAT OF SEVERE WEATHER EXPECTED MONDAY...

.DAY ONE...REST OF TONIGHT...

THUNDERSTORM OUTLOOK...
ISOLATED THUNDERSTORMS ARE POSSIBLE OVERNIGHT...BUT SEVERE WEATHER
IS NOT EXPECTED.

DISCUSSION...
WHILE A SURFACE COLD FRONT HAD PUSHED LOW LEVEL MOISTURE BACK TO THE
GULF COAST...ANOTHER LAYER OF MOIST AIR AT MID LEVELS HAD BEGUN TO
RETURN NORTHWARD. RELATIVELY COLD TEMPERATURES AT UPPER LEVELS WILL
RESULT IN WEAK INSTABILITY...AND THE POSSIBILITY OF BOTH SHOWERS AND
A FEW THUNDERSTORMS. THE GREATEST CHANCE OF RAIN AND THUNDER
STRETCHES ALONG THE EDGE OF THE RETURNING MOISTURE...FROM WESTERN
NORTH TEXAS UP THROUGH SOUTHERN AND SOUTHEASTERN OKLAHOMA. THE
STRONGEST THUNDERSTORM UPDRAFTS MAY PRODUCE A FEW CLOUD TO GROUND
LIGHTNING STRIKES...AND SMALL HAIL.

PROBABILITY TABLE...
VALID THROUGH 700 AM CDT SUNDAY MAY 9.
PROBABILITY OF THUNDERSTORMS OCCURRING IN THE
NWS NORMAN COUNTY WARNING AREA...40 PERCENT
PROBABILITY OF SEVERE STORMS IF STORMS OCCUR...10 PERCENT.

OTHER HAZARDOUS WEATHER...
NONE.

.DAYS TWO THROUGH SEVEN...SUNDAY THROUGH FRIDAY...

THUNDERSTORM OUTLOOK...
...SUNDAY...
THE COVERAGE OF RAIN AND THUNDERSTORMS IS FORECAST TO INCREASE
DURING THE DAY SUNDAY...AS GULF MOISTURE INCREASES FROM MID LEVELS
INTO THE LOW LEVELS OF THE ATMOSPHERE. MUCH OF THE ACTIVITY WILL
PRODUCE CLOUD TO GROUND LIGHTNING AND SMALL HAIL. AS MOISTURE
DEEPENS...INSTABILITY WILL ALSO INCREASE...ESPECIALLY LATE SUNDAY
AND SUNDAY NIGHT. AT THE SAME TIME...A CAP WILL BUILD FROM WEST TO
EAST...PUSHING THE GREATER CHANCE OF THUNDERSTORMS TOWARD AND EAST
OF INTERSTATE 35. A FEW THUNDERSTORMS MAY BECOME SEVERE IN THAT
REGION OF CENTRAL AND EASTERN OKLAHOMA...WITH THE MAIN THREAT BEING
LARGE HAIL.

...MONDAY...
THE WEATHER ON MONDAY...HOWEVER...IS OF GREATER CONCERN. A SMALL BUT
WELL DEFINED UPPER LEVEL DISTURBANCE WILL EJECT FROM THE SOUTHERN
ROCKIES...PRODUCING A DEEP SURFACE LOW THAT WILL LIKELY TRACK ACROSS
KANSAS. THE LOW WILL DRAG A DRYLINE INTO OKLAHOMA AND WESTERN NORTH
TEXAS...MOST LIKELY BY EARLY AFTERNOON. BY THAT TIME...RICH GULF
MOISTURE WILL BE TRANSPORTED INTO THE REGION AHEAD OF THE DRYLINE.
ALTHOUGH A STRONG CAP WILL BE IN PLACE...LIFTING ALONG THE DRYLINE
SHOULD BE SUFFICIENT TO PRODUCE THUNDERSTORMS MONDAY AFTERNOON AND
EVENING. INSTABILITY AND WIND SHEAR ARE FORECAST TO BE MORE THAN
ADEQUATE FOR SUPERCELL STORMS...SOME OF WHICH MAY BE LARGE AND
DAMAGING. CURRENTLY...THE GREATEST COVERAGE OF STORMS IS FORECAST IN
NORTHERN OKLAHOMA...BUT ISOLATED CELLS...EQUALLY SEVERE...COULD FORM
DOWN THE DRYLINE INTO WESTERN AND CENTRAL OKLAHOMA...AND WESTERN
NORTH TEXAS.

SEVERE THUNDERSTORMS ON MONDAY AFTERNOON AND EVENING...MAY MOVE AT
SPEEDS GREATER THAN 45 MPH...LEAVING LITTLE TIME FOR PEOPLE TO REACT
TO WARNINGS. YOU ARE ENCOURAGED TO THINK AHEAD TO WHERE YOU WILL BE
ON MONDAY...HOW YOU WILL RECEIVE WEATHER WARNINGS...AND WHERE YOU
WILL SHELTER IF A STORM APPROACHES YOUR LOCATION.

...TUESDAY THROUGH FRIDAY...
THE WEATHER SYSTEM ARRIVING MONDAY WILL LEAVE A FRONTAL BOUNDARY
STALLED SOMEWHERE ACROSS THE SOUTHERN PLAINS. FROM MID TO LATE
WEEK...ADDITIONAL UPPER LEVEL DISTURBANCES WILL INTERACT WITH THE
FRONT...MAINTAINING A CHANCE OF SEVERE STORMS...AND AN INCREASING
CHANCE OF HEAVY RAINFALL.

OTHER HAZARDOUS WEATHER...

OF THE DRYLINE ON MONDAY AFTERNOON.

356 AM CDT SUN MAY 9 2010

.DISCUSSION...
SCATTERED SHOWERS AND A FEW THUNDERSTORMS CONTINUE TO DEVELOP ACROSS
THE AREA THIS MORNING WITH BROAD ISENTROPIC LIFT. THERE MAY BE A
LULL IN THE ACTIVITY LATER THIS MORNING BUT DEEPER MOISTURE WILL BE
RETURNING NORTHWARD LATER TODAY AND TONIGHT WITH CHANCES FOR SHOWERS
AND THUNDERSTORMS INCREASING. A FEW STRONG ELEVATED STORMS WILL BE
POSSIBLE LATER TONIGHT BUT SEVERE WEATHER THREAT WILL INCREASE
SIGNIFICANTLY ON MONDAY. WELL ADVERTISED SEVERE THREAT STILL APPEARS
TO BE ON TRACK WITH STRONG S/W TROUGH EJECTING FROM THE ROCKIES INTO
THE CENTRAL PLAINS AND DRYLINE PUSHING EASTWARD INTO WESTERN PARTS
OF OK AND NORTH TEXAS. STRONG INSTABILITY AND SHEAR WILL MORE THAN
ADEQUATE FOR SUPERCELLS WITH POTENTIALLY LARGE DAMAGING STORMS
POSSIBLE. STORMS SHOULD MOVE OFF THE NORTHEAST MONDAY AS UPPER
SYSTEM ZIPS NORTHEAST. COLD FRONT WILL PUSH SOUTHWARD INTO
THE AREA MONDAY NIGHT BEFORE STALLING OVER SOUTHERN PORTIONS OF THE
AREA EARLY TUESDAY. A FEW STORMS WILL BE POSSIBLE NEAR THIS BOUNDARY
TUESDAY AFTERNOON AND EVENING BUT COVERAGE WILL BE LIMITED BY LACK
OF UPPER SUPPORT. UPPER TROUGH TO THE WEST...SURFACE BOUNDARY
LINGERING IN THE AREA...AND ABUNDANT MOISTURE WILL LEAD TO POTENTIAL
FOR SHOWERS AND THUNDERSTORMS MID TO LATE WEEK. A PORTION OF THE
UPPER TROUGH EJECTS NEWD OVER THE AREA WEDNESDAY INTO THURSDAY WHICH
MAY ENHANCE THUNDERSTORM CHANCES DURING THAT PERIOD AND WILL ALSO
LIKELY PUSH THE FRONTAL BOUNDARY FURTHER SOUTH. CHANCES FOR SHOWERS
AND THUNDERSTORMS WILL DECREASE BY THE WEEKEND AS UPPER TROUGH
GRADUALLY SHIFTS EASTWARD WHILE WEAKENING AND WEAK FRONTAL BOUNDARY
GENERALLY REMAINS SOUTH OF THE AREA.

THIS HAZARDOUS WEATHER OUTLOOK COVERS NORTHERN...WESTERN...
CENTRAL...AND SOUTHERN OKLAHOMA...AND WESTERN NORTH TEXAS.

.DAY ONE...TONIGHT...

THUNDERSTORM OUTLOOK...
ISOLATED SEVERE STORMS WILL BE POSSIBLE OVERNIGHT...MAINLY IN THE
AREA NEAR AND EAST OF INTERSTATE 35.

DISCUSSION...
SCATTERED SHOWERS AND THUNDERSTORMS WILL CONTINUE THROUGH THE
EVENING AND OVERNIGHT HOURS. AN INCREASE IN COVERAGE MAY OCCUR NEAR
AND EAST OF INTERSTATE 35 LATE TONIGHT...AS A STRENGTHENING
LOW-LEVEL JET INTERACTS WITH AN APPROACHING UPPER-LEVEL JET STREAM.
INSTABILITY ROOTED ABOVE THE SURFACE...AND WIND SHEAR...WILL BE
SUFFICIENT TO SUPPORT AN ORGANIZED SEVERE STORM OR TWO...WITH THE
MAIN CONCERN BEING HAIL BETWEEN 1 AND 1.5 INCHES IN DIAMETER. THIS
ACTIVITY COULD PERSIST INTO THE DAYLIGHT HOURS ON MONDAY...OVER
CENTRAL AND NORTH CENTRAL OKLAHOMA.

PROBABILITY TABLE...
VALID THROUGH 700 AM CDT MONDAY MAY 10.
PROBABILITY OF THUNDERSTORMS OCCURRING IN THE
NWS NORMAN COUNTY WARNING AREA...100 PERCENT
PROBABILITY OF SEVERE STORMS IF STORMS OCCUR...20 PERCENT.

OTHER HAZARDOUS WEATHER...
NONE.

.DAYS TWO THROUGH SEVEN...MONDAY THROUGH SATURDAY...

THUNDERSTORM OUTLOOK...
A SMALL...BUT WELL DEFINED UPPER-LEVEL DISTURBANCE WILL EJECT FROM
THE SOUTHERN ROCKIES ON MONDAY...PRODUCING A DEEP SURFACE LOW THAT
WILL TRACK ACROSS KANSAS. THE LOW WILL DRAG A DRYLINE INTO OKLAHOMA
AND WESTERN NORTH TEXAS...MOST LIKELY BY EARLY AFTERNOON. BY THAT
TIME...RICH GULF MOISTURE WILL BE TRANSPORTED INTO THE REGION AHEAD
OF THE DRYLINE. ALTHOUGH A STRONG CAP WILL BE IN PLACE INITIALLY...
RISING MOTION ALONG AND JUST EAST OF THE DRY LINE IS EXPECTED TO BE
SUFFICIENT TO PRODUCE THUNDERSTORMS MONDAY AFTERNOON AND MONDAY
EVENING. INSTABILITY AND WIND SHEAR ARE FORECAST TO BE MORE THAN
ADEQUATE FOR SUPERCELL STORMS...CAPABLE OF PRODUCING VERY LARGE AND
DESTRUCTIVE HAIL...DAMAGING STRAIGHT-LINE WINDS...AND TORNADOES.
CURRENTLY...THE GREATEST COVERAGE OF STORMS IS FORECAST ACROSS
NORTH-CENTRAL OKLAHOMA...BUT ISOLATED CELLS...EQUALLY SEVERE...COULD
FORM FARTHER SOUTH INTO WESTERN AND CENTRAL OKLAHOMA...AND WESTERN
NORTH TEXAS.

SEVERE THUNDERSTORMS ON MONDAY AFTERNOON AND EVENING MAY MOVE AT
SPEEDS GREATER THAN 45 MPH...LEAVING LITTLE TIME FOR PEOPLE TO REACT
TO WARNINGS. YOU ARE ENCOURAGED TO THINK AHEAD TO WHERE YOU WILL BE
ON MONDAY AFTERNOON AND EVENING...HOW YOU WILL RECEIVE WEATHER
WARNINGS...AND WHERE YOU WILL SHELTER IF A STORM APPROACHES YOUR
LOCATION.

THE WEATHER SYSTEM ARRIVING MONDAY WILL LEAVE A FRONTAL BOUNDARY
STALLED ACROSS THE SOUTHERN PLAINS. FROM MID TO LATE WEEK...
ADDITIONAL UPPER-LEVEL DISTURBANCES WILL INTERACT WITH THE
FRONT...MAINTAINING A CHANCE OF SEVERE STORMS AND AN INCREASING
CHANCE OF HEAVY RAINFALL ACCUMULATIONS.

OTHER HAZARDOUS WEATHER...
ON MONDAY AFTERNOON...AFTER THE DRYLINE HAS PASSED...VERY STRONG AND
POSSIBLY DAMAGING WINDS WILL BE POSSIBLE ACROSS PORTIONS OF WESTERN
AND NORTHERN OKLAHOMA. A HIGH WIND WATCH IS IN EFFECT FOR THE
NORTHWESTERN ONE THIRD OF OKLAHOMA.

THE NEXT SCHEDULED HAZARDOUS WEATHER OUTLOOK WILL BE ISSUED BY 5 AM
MONDAY.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NORMAN OK
415 AM CDT MON MAY 10 2010

.DISCUSSION...
MAIN FORECAST CONCERN WILL BE WITH POTENTIAL FOR SIGNIFICANT SEVERE
WEATHER OUTBREAK LATER THIS AFTERNOON AND EVENING. MODELS HAVE BEEN
FAIRLY CONSISTENT THE PAST FEW DAYS WITH S/W TROUGH EJECTING FROM
THE ROCKIES INTO THE PLAINS THIS AFTERNOON AND EVENING WITH SURFACE
LOW TRACKING ACROSS SRN KANSAS AND DRYLINE PUNCHING INTO WESTERN
OK/N TX. EXCESSIVE WINDS EXPECTED TO DEVELOP BEHIND THE DRYLINE WITH
DEEP MIXING INTO THE STRONG WINDS ALOFT. WILL GO AHEAD AND UPGRADE
FAR NW TO HIGH WIND WARNING. WILL LEAVE WATCH IN PLACE FARTHER EAST
WITH MORE UNCERTAINTY ABOUT HOW RAPIDLY EASTWARD DRYLINE WILL
ADVANCE. MOISTURE WILL SURGE NORTHWARD INTO THE AREA TODAY WITH
STRONG INSTABILITY DEVELOPING IN ADVANCE OF THE DRYLINE. SHEAR WILL
ALSO INCREASE AS STRONG MID LEVEL JET ASSOCIATED WITH THE ADVANCING
S/W TROUGH MOVES OVER THE AREA. AS PER SWODY1 EXPECT STORMS TO
INITIATE ALONG THE DRYLINE MID TO LATE AFTERNOON AS IT PUSHES TOWARD
CENTRAL PARTS OF THE FA. STORMS WILL RAPIDLY BECOME SEVERE GIVEN THE
STRONG INSTABILITY AND SHEAR WITH SUPERCELLS PRODUCING LARGE
HAIL...TORNADOES AND DAMAGING WINDS LIKELY. GREATEST COVERAGE OF
STORMS WILL LIKELY BE OVER NRN PARTS OF THE FA BUT LESS WIDESPREAD
BUT EQUALLY SEVERE STORMS WILL REMAIN POSSIBLE SOUTHWARD INTO N TX
ZONES. THE SEVERE STORMS SHOULD MOVE RAPIDLY ENEWD DURING THE
EVENING WITH MOST OF THE ACTIVITY EXITING THE FA BY LATE TONIGHT.
ASSOCIATED FRONTAL BOUNDARY WILL PUSH SOUTHWARD INTO THE AREA
TONIGHT BEFORE STALLING IN SRN SECS EARLY TUESDAY. A FEW STORMS WILL
BE POSSIBLE TUESDAY AFTERNOON IN THE VICINITY OF THE WEAK BOUNDARY
AS IT BEGINS TO DRIFT BACK NORTHWARD. WARM FRONT WILL CONTINUE TO
LIFT NORTHWARD TUESDAY NIGHT WITH MORE WIDESPREAD STORMS AS LOW
LEVEL JET INTERACTS WITH RETREATING WARM FRONT. MORE SEVERE WEATHER
AND THREAT OF HEAVY RAIN POSSIBLE WEDNESDAY/WEDNESDAY NIGHT AS UPPER
LOW OVER THE ROCKIES EJECTS NORTHEASTWARD AND FRONT BEGINS TO SURGE
BACK SOUTHWARD. BROAD UPPER TROUGH WILL REMAIN TO THE WEST THROUGH
THE REMAINDER OF THE WEEK. FRONTAL BOUNDARY LINGERING NEAR THE AREA
AND DISTURBANCES MOVING THROUGH THE SOUTHWEST FLOW ALOFT LEAD TO
CONTINUED PRECIP CHANCES THROUGH THE PERIOD.

THIS HAZARDOUS WEATHER OUTLOOK COVERS NORTHERN...WESTERN...
CENTRAL...AND SOUTHERN OKLAHOMA...AND WESTERN NORTH TEXAS.

.DAY ONE...TODAY AND TONIGHT...

THUNDERSTORM OUTLOOK...
THERE IS A HIGH RISK OF SEVERE THUNDERSTORMS TODAY EAST OF A LINE
FROM CUSHING SOUTH TO PRAGUE... SEMINOLE... SASAKWA AND CALVIN.
THERE IS A MODERATE RISK TO THE WEST OF THE HIGH RISK AND EAST OF A
LINE FROM MEDFORD... SOUTH TO MARSHALL... OKLAHOMA CITY...LINDSEY
AND HEALDTON... THEN EAST TO TISHOMINGO AND CANEY. THERE IS A SLIGHT
RISK WEST OF THE MODERATE RISK AND EAST OF A LINE FROM ALVA...
WATONGA... LAWTON... WICHITA FALLS AND SEYMOUR TEXAS.

TIMING...
MOST LIKELY TIME FOR SEVERE THUNDERSTORM DEVELOPMENT WILL BE FROM 3
PM THROUGH MIDNIGHT.

IMPACTS...
THE MAIN IMPACTS WILL BE VERY LARGE HAIL TO THE SIZE OF BASEBALLS OR
LARGER AND TORNADOES.

RECOMMENDED ACTIONS...
STORM SPOTTER GROUPS AND EMERGENCY MANAGEMENT PERSONNEL ACROSS THE
RISK AREAS SHOULD BE PREPARED FOR SEVERE WEATHER OPERATIONS THIS
AFTERNOON AND EVENING.

DISCUSSION...
SCATTERED THUNDERSTORMS WILL BE POSSIBLE THIS MORNING... MAINLY
ALONG AND EAST OF A WICHITA FALLS TO OKLAHOMA CITY TO PONCA CITY
LINE. THESE STORMS ARE EXPECTED TO REMAIN ELEVATED IN NATURE WITH
THE STRONGEST STORMS CAPABLE OF PRODUCING MARGINALLY SEVERE HAIL.
THIS ACTIVITY IS EXPECTED TO MOVE NORTHEAST OUT OF THE AREA LATER
THIS MORNING.

MEANWHILE... A SMALL... BUT POTENT UPPER LEVEL DISTURBANCE WILL MOVE
FROM THE SOUTHERN ROCKIES OUT INTO THE SOUTHERN PLAINS TODAY. AS
THIS OCCURS AN AREA OF SURFACE LOW PRESSURE WILL DEVELOP ACROSS
SOUTHEAST COLORADO AND TRACK EAST ACROSS SOUTHERN KANSAS. A DRY LINE
WILL TAKE SHAPE TO THE SOUTH OF THE SURFACE LOW PRESSURE ACROSS THE
OKLAHOMA AND TEXAS PANHANDLES THIS MORNING. THIS DRY LINE WILL MOVE
QUICKLY EAST TOWARD WESTERN OKLAHOMA AND WESTERN NORTH TEXAS BY
MIDDAY... AND TOWARD THE I-35 CORRIDOR BY EARLY EVENING. IN ADVANCE
OF THE DRY LINE... VERY MOIST AND UNSTABLE AIR WILL SURGE NORTH
ACROSS TEXAS... INTO OKLAHOMA AND KANSAS.

INITIALLY A WARM LAYER OF AIR ABOVE THE SURFACE WILL LIMIT
THUNDERSTORM DEVELOPMENT. HOWEVER... BY THIS AFTERNOON... SURFACE
HEATING AND COOLING ALOFT BY THE APPROACH OF THE UPPER LEVEL
DISTURBANCE WILL OVERCOME THIS CAPPING INVERSION AND THUNDERSTORMS
ARE EXPECTED TO DEVELOP ALONG AND AHEAD OF THE DRY LINE ACROSS
PORTIONS OF KANSAS SOUTHWARD INTO NORTHERN AND CENTRAL OKLAHOMA. AS
VERY STRONG AND FAVORABLE WIND FIELDS WILL EXIST... ALONG WITH HIGH
AMOUNTS OF INSTABILITY... SUPERCELL STORMS ARE LIKELY. THESE STORMS
WILL BE CAPABLE OF PRODUCING VERY LARGE AND DESTRUCTIVE
HAIL...DAMAGING STRAIGHT-LINE WINDS...AND TORNADOES... ESPECIALLY
ACROSS THE MODERATE AND HIGH RISK AREAS THIS AFTERNOON AND EVENING.

PROBABILITY TABLE...
VALID THROUGH 700 AM CDT TUESDAY MAY 11.
PROBABILITY OF THUNDERSTORMS OCCURRING IN THE
NWS NORMAN COUNTY WARNING AREA...100 PERCENT
PROBABILITY OF SEVERE STORMS IF STORMS OCCUR..100 PERCENT.

STALLED ACROSS THE SOUTHERN PLAINS. FROM MID TO LATE WEEK...
ADDITIONAL UPPER-LEVEL DISTURBANCES WILL INTERACT WITH THE
FRONT...MAINTAINING A CHANCE OF SEVERE STORMS AND AN INCREASING
CHANCE OF HEAVY RAINFALL ACCUMULATIONS.

OTHER HAZARDOUS WEATHER...
NONE.

THE NEXT SCHEDULED HAZARDOUS WEATHER OUTLOOK WILL BE ISSUED BY NOON
TODAY.

FAIRLY CONSISTENT THE PAST FEW DAYS WITH S/W TROUGH EJECTING FROM
THE ROCKIES INTO THE PLAINS THIS AFTERNOON AND EVENING WITH SURFACE
LOW TRACKING ACROSS SRN KANSAS AND DRYLINE PUNCHING INTO WESTERN
OK/N TX. EXCESSIVE WINDS EXPECTED TO DEVELOP BEHIND THE DRYLINE WITH
DEEP MIXING INTO THE STRONG WINDS ALOFT. WILL GO AHEAD AND UPGRADE
FAR NW TO HIGH WIND WARNING. WILL LEAVE WATCH IN PLACE FARTHER EAST
WITH MORE UNCERTAINTY ABOUT HOW RAPIDLY EASTWARD DRYLINE WILL
ADVANCE. MOISTURE WILL SURGE NORTHWARD INTO THE AREA TODAY WITH
STRONG INSTABILITY DEVELOPING IN ADVANCE OF THE DRYLINE. SHEAR WILL
ALSO INCREASE AS STRONG MID LEVEL JET ASSOCIATED WITH THE ADVANCING
S/W TROUGH MOVES OVER THE AREA. AS PER SWODY1 EXPECT STORMS TO
INITIATE ALONG THE DRYLINE MID TO LATE AFTERNOON AS IT PUSHES TOWARD
CENTRAL PARTS OF THE FA. STORMS WILL RAPIDLY BECOME SEVERE GIVEN THE
STRONG INSTABILITY AND SHEAR WITH SUPERCELLS PRODUCING LARGE
HAIL...TORNADOES AND DAMAGING WINDS LIKELY. GREATEST COVERAGE OF
STORMS WILL LIKELY BE OVER NRN PARTS OF THE FA BUT LESS WIDESPREAD
BUT EQUALLY SEVERE STORMS WILL REMAIN POSSIBLE SOUTHWARD INTO N TX
ZONES. THE SEVERE STORMS SHOULD MOVE RAPIDLY ENEWD DURING THE
EVENING WITH MOST OF THE ACTIVITY EXITING THE FA BY LATE TONIGHT.
ASSOCIATED FRONTAL BOUNDARY WILL PUSH SOUTHWARD INTO THE AREA
TONIGHT BEFORE STALLING IN SRN SECS EARLY TUESDAY. A FEW STORMS WILL
BE POSSIBLE TUESDAY AFTERNOON IN THE VICINITY OF THE WEAK BOUNDARY
AS IT BEGINS TO DRIFT BACK NORTHWARD. WARM FRONT WILL CONTINUE TO
LIFT NORTHWARD TUESDAY NIGHT WITH MORE WIDESPREAD STORMS AS LOW
LEVEL JET INTERACTS WITH RETREATING WARM FRONT. MORE SEVERE WEATHER
AND THREAT OF HEAVY RAIN POSSIBLE WEDNESDAY/WEDNESDAY NIGHT AS UPPER
LOW OVER THE ROCKIES EJECTS NORTHEASTWARD AND FRONT BEGINS TO SURGE
BACK SOUTHWARD. BROAD UPPER TROUGH WILL REMAIN TO THE WEST THROUGH
THE REMAINDER OF THE WEEK. FRONTAL BOUNDARY LINGERING NEAR THE AREA
AND DISTURBANCES MOVING THROUGH THE SOUTHWEST FLOW ALOFT LEAD TO
CONTINUED PRECIP CHANCES THROUGH THE PERIOD.

PUBLIC INFORMATION STATEMENT
NATIONAL WEATHER SERVICE NORMAN OK
1108 AM CDT MON MAY 10 2010

SEVERE THUNDERSTORMS ARE EXPECTED ACROSS PARTS OF THE AREA THIS
AFTERNOON INTO THIS EVENING. THE NATIONAL WEATHER SERVICE IN NORMAN
URGES YOU TO TAKE THIS TIME TO THINK ABOUT WHAT YOU WILL DO TO STAY
SAFE IF STORMS APPROACH.

MAKE SURE YOU HAVE MORE THAN ONE SOURCE OF LOCAL WEATHER WARNINGS
AND INFORMATION. IF YOU HAVE A WEATHER RADIO... BE SURE IT IS WORKING
PROPERLY.

CHECK THE WEATHER OFTEN THROUGHOUT THE DAY. IF YOU WILL BE TRAVELING
OR HAVE OUTDOOR ACTIVITIES PLANNED... BE SURE YOU CAN GET THE LATEST
WEATHER INFORMATION AND KEEP UP WITH DEVELOPING SEVERE WEATHER.

IF STORMS THREATEN YOU... REMEMBER THESE BASIC SAFETY GUIDELINES:

SEVERE THUNDERSTORMS PRODUCE LARGE HAIL AND DAMAGING WINDS. IF YOU
HEAR A SEVERE THUNDERSTORM WARNING FOR YOUR LOCATION... SEEK SHELTER
IN A STURDY BUILDING... AND STAY AWAY FROM DOORS AND WINDOWS. IF
YOU'RE DRIVING... THINK ABOUT FINDING SUBSTANTIAL SHELTER TO AVOID
BEING CAUGHT IN LARGE HAIL AND STRONG WINDS. AND REMEMBER THAT EVERY
THUNDERSTORM PRODUCES DANGEROUS LIGHTNING... AND THAT NO PLACE OUTSIDE
IS SAFE.

IF YOU HEAR A TORNADO WARNING FOR YOUR LOCATION... OR FEEL THREATENED
BY A TORNADO... YOU'LL NEED TO ACT QUICKLY TO PROTECT YOURSELF. AN
UNDERGROUND SHELTER OR SAFE ROOM IS THE SAFEST PLACE. IF NO
UNDERGROUND SHELTER IS AVAILABLE... TAKE COVER IN A STURDY BUILDING.
GO TO THE LOWEST FLOOR AND STAY AWAY FROM DOORS... WINDOWS AND OUTSIDE
WALLS. YOUR GOAL IS TO PUT AS MANY WALLS BETWEEN YOU AND THE TORNADO
AS YOU CAN. YOU SHOULD PROTECT YOURSELF FROM FLYING AND FALLING
DEBRIS WITH PILLOWS OR BLANKETS. MOBILE HOMES AND VEHICLES ARE NOT
SAFE IN A TORNADO... SO BE SURE YOU HAVE PLENTY OF TIME TO GET TO A
STURDY SHELTER.

MONITOR THE LATEST INFORMATION FROM THE NATIONAL WEATHER SERVICE IN
NORMAN BY LISTENING TO WEATHER RADIO OR BY VISITING OUR WEBSITE AT
WEATHER.GOV/NORMAN.

AND TEXAS PANHANDLES. AT THE SAME TIME...AN UPPER LEVEL STORM WAS
MOVING OUT OF THE NEW MEXICO AND COLORADO ROCKIES INTO THE PLAINS.
COOL STABLE AIR WAS QUICKLY BEING REPLACED WITH HUMID...MORE
UNSTABLE AIR...AS A WARM FRONT LOCATED FROM NORTHEAST TEXAS INTO
WEST CENTRAL OKLAHOMA MOVED NORTH.

BY LATE AFTERNOON...CONSIDERABLE CHANGES WILL HAVE OCCURRED. THE
DRYLINE WILL BE LOCATED FROM NEAR CHEROKEE...TO WATONGA...TO
LAWTON...TO NEAR ARCHER CITY TEXAS. THE WARM FRONT WILL EXTEND
FROM AROUND PONCA CITY INTO EAST CENTRAL OKLAHOMA. EAST OF THE
DRYLINE AND SOUTH OF THE WARM FRONT THE ATMOSPHERE WILL BE VERY
UNSTABLE. A CAPPING LAYER OF WARM AIR WILL HAVE ERODED SOMEWHAT
MAKING THE CHANCES FOR STORM DEVELOPMENT GREATER.

THE UPPER LEVEL STORM WILL BE NEARBY RESULTING IN VERY STRONG WIND
SHEAR. THIS WIND SHEAR...COUPLED WITH THE HUMID UNSTABLE AIR... WILL
SUPPORT SUPERCELL THUNDERSTORM DEVELOPMENT. STORMS THAT DEVELOP
WILL LIKELY BECOME SEVERE QUICKLY AND HAVE THE POTENTIAL TO PRODUCE
TORNADOES AND VERY LARGE HAIL. THE STORMS ARE EXPECTED TO MOVE EAST
AT 40 TO 50 MPH. ALTHOUGH THE POTENTIAL FOR SIGNIFICANT SEVERE
WEATHER IS HIGH...THE DURATION WILL BE BRIEF AS THE STORMS QUICKLY
MOVE EAST INTO EASTERN OKLAHOMA.

PROBABILITY TABLE...
VALID THROUGH 700 AM CDT TUESDAY MAY 11.
PROBABILITY OF THUNDERSTORMS OCCURRING IN THE
NWS NORMAN COUNTY WARNING AREA...90 PERCENT
PROBABILITY OF SEVERE STORMS IF STORMS OCCUR..100 PERCENT.

OTHER HAZARDOUS WEATHER...
THIS AFTERNOON...AFTER THE DRYLINE HAS PASSED...VERY STRONG AND
POSSIBLY DAMAGING WINDS WILL BE POSSIBLE ACROSS PORTIONS OF WESTERN
AND NORTHERN OKLAHOMA AND WESTERN NORTH TEXAS.

.DAYS TWO THROUGH SEVEN...TUESDAY THROUGH SUNDAY...

THUNDERSTORM OUTLOOK...
THE WEATHER SYSTEM ARRIVING MONDAY WILL LEAVE A FRONTAL BOUNDARY
STALLED ACROSS THE SOUTHERN PLAINS. FROM MID TO LATE WEEK...
ADDITIONAL UPPER-LEVEL DISTURBANCES WILL INTERACT WITH THE
FRONT...MAINTAINING A CHANCE OF SEVERE STORMS AND AN INCREASING
CHANCE OF HEAVY RAINFALL ACCUMULATIONS.

OTHER HAZARDOUS WEATHER...
NONE.

UPDATE...
DRYLINE BEGINNING TO MOVE EAST ACROSS THE PANHANDLES WITH WINDS
GUSTING INTO THE 40 TO 50 MPH RANGE BEHIND THE BOUNDARY. HAVE
UPGRADED HIGH WIND WATCH TO WARNING IN WOODS COUNTY AND CONVERTED
REST OF WATCH TO WIND ADVISORY. DRYLINE EXPECTED TO MIX EAST TO
ABOUT A MEDFORD TO NEAR WATONGA AND FREDERICK OKLAHOMA TO SEYMOUR
TEXAS LINE LATE THIS AFTERNOON. SEVERE STORMS WILL BE LIKELY THIS
AFTERNOON AND EARLY EVENING ALONG AND AHEAD OF THE DRYLINE... WITH
STRONG WINDS/LARGE HAIL/TORNADOES A CONCERN. BLOWING DUST MAY ALSO
BECOME AN ISSUE BEHIND THE DRYLINE THIS AFTERNOON. HAVE ADJUSTED
POPS/WX GRIDS. ALSO ADJUSTED WINDS/DEWPOINTS TO SHOW CURRENT
THOUGHTS ON DRYLINE POSITION. LOWERED HIGHS IN NE PORTION OF FA
WHERE TEMPS ARE STILL IN THE MID 50S AND CLOUDY LATE THIS MORNING.

MAXWELL

PREV DISCUSSION... /ISSUED 605 AM CDT MON MAY 10 2010/

AVIATION...
WIDESPREAD MVFR/IFR CIGS ACROSS THE AREA THIS MORNING. WARM FRONT
FROM SE TX INTO OK/TX PANHANDLES THIS MORNING WILL LIFT NWD TODAY.
EXPECT LOW CLOUDS TO PERSIST NORTH OF THE FRONT AND CIGS MAY LOWER
SOME MORE EARLY THIS MORNING. DRYLINE WILL PUNCH INTO WRN OK/N TX AS
SFC LOW MOVES THROUGH SRN KS. VERY STRONG SW TO W WINDS WILL DEVELOP
BEHIND THE DRYLINE AT WRN OK SITES DURING THE AFTERNOON. FARTHER EAST
CIGS WILL RISE DURING THE LATE MORNING/EARLY AFTERNOON AS WARM FRONT
MOVES NORTH OF THE AREA. STRONG/SEVERE STORMS WILL DEVELOP ALONG THE
DRYLINE LATE AFTN/ERLY EVE AND WILL INCLUDE IN ERN TAFS.

PREV DISCUSSION... /ISSUED 415 AM CDT MON MAY 10 2010/

DISCUSSION...
MAIN FORECAST CONCERN WILL BE WITH POTENTIAL FOR SIGNIFICANT SEVERE
WEATHER OUTBREAK LATER THIS AFTERNOON AND EVENING. MODELS HAVE BEEN
FAIRLY CONSISTENT THE PAST FEW DAYS WITH S/W TROUGH EJECTING FROM
THE ROCKIES INTO THE PLAINS THIS AFTERNOON AND EVENING WITH SURFACE
LOW TRACKING ACROSS SRN KANSAS AND DRYLINE PUNCHING INTO WESTERN
OK/N TX. EXCESSIVE WINDS EXPECTED TO DEVELOP BEHIND THE DRYLINE WITH
DEEP MIXING INTO THE STRONG WINDS ALOFT. WILL GO AHEAD AND UPGRADE
FAR NW TO HIGH WIND WARNING. WILL LEAVE WATCH IN PLACE FARTHER EAST
WITH MORE UNCERTAINTY ABOUT HOW RAPIDLY EASTWARD DRYLINE WILL
ADVANCE. MOISTURE WILL SURGE NORTHWARD INTO THE AREA TODAY WITH
STRONG INSTABILITY DEVELOPING IN ADVANCE OF THE DRYLINE. SHEAR WILL
ALSO INCREASE AS STRONG MID LEVEL JET ASSOCIATED WITH THE ADVANCING
S/W TROUGH MOVES OVER THE AREA. AS PER SWODY1 EXPECT STORMS TO
INITIATE ALONG THE DRYLINE MID TO LATE AFTERNOON AS IT PUSHES TOWARD
CENTRAL PARTS OF THE FA. STORMS WILL RAPIDLY BECOME SEVERE GIVEN THE
STRONG INSTABILITY AND SHEAR WITH SUPERCELLS PRODUCING LARGE
HAIL...TORNADOES AND DAMAGING WINDS LIKELY. GREATEST COVERAGE OF
STORMS WILL LIKELY BE OVER NRN PARTS OF THE FA BUT LESS WIDESPREAD
BUT EQUALLY SEVERE STORMS WILL REMAIN POSSIBLE SOUTHWARD INTO N TX
ZONES. THE SEVERE STORMS SHOULD MOVE RAPIDLY ENEWD DURING THE
EVENING WITH MOST OF THE ACTIVITY EXITING THE FA BY LATE TONIGHT.
ASSOCIATED FRONTAL BOUNDARY WILL PUSH SOUTHWARD INTO THE AREA
TONIGHT BEFORE STALLING IN SRN SECS EARLY TUESDAY. A FEW STORMS WILL
BE POSSIBLE TUESDAY AFTERNOON IN THE VICINITY OF THE WEAK BOUNDARY
AS IT BEGINS TO DRIFT BACK NORTHWARD. WARM FRONT WILL CONTINUE TO
LIFT NORTHWARD TUESDAY NIGHT WITH MORE WIDESPREAD STORMS AS LOW
LEVEL JET INTERACTS WITH RETREATING WARM FRONT. MORE SEVERE WEATHER
AND THREAT OF HEAVY RAIN POSSIBLE WEDNESDAY/WEDNESDAY NIGHT AS UPPER
LOW OVER THE ROCKIES EJECTS NORTHEASTWARD AND FRONT BEGINS TO SURGE
BACK SOUTHWARD. BROAD UPPER TROUGH WILL REMAIN TO THE WEST THROUGH
THE REMAINDER OF THE WEEK. FRONTAL BOUNDARY LINGERING NEAR THE AREA
AND DISTURBANCES MOVING THROUGH THE SOUTHWEST FLOW ALOFT LEAD TO
CONTINUED PRECIP CHANCES THROUGH THE PERIOD.

NORTH TEXAS...GIVING WAY TO MOSTLY SUNNY SKIES. MOST OF THE CLOUD
COVER WAS LOCATED TO THE NORTHEAST OF AN ADVANCING WARM FRONT OVER
CENTRAL OKLAHOMA. THESE CLOUDS SHOULD CONTINUE TO BREAK UP OVER THE

POINTS WERE INCREASING INTO THE MID TO UPPER 60S. WHEN COMBINED
WITH ABUNDANT SUNSHINE...THE ATMOSPHERE ACROSS WESTERN OKLAHOMA AND
WESTERN NORTH TEXAS WAS RAPIDLY BECOMING UNSTABLE. THE AXIS OF
GREATEST INSTABILITY STRETCHED FROM NEAR WICHITA FALLS TO NEAR
WATONGA. A WARM LAYER OF AIR ALOFT IS PREVENTING THUNDERSTORM
DEVELOPMENT...BUT THIS CAPPING INVERSION WILL CONTINUE TO WEAKEN
OVER THE NEXT SEVERAL HOURS.

A DRYLINE IS CONTINUING TO SHARPEN FROM SOUTHWEST KANSAS INTO THE
TEXAS PANHANDLE. THE DRYLINE EXTENDED FROM NEAR GARDEN CITY
KANSAS...TO BEAVER OKLAHOMA...TO CANADIAN TEXAS...TO LAMESA TEXAS.
THE DRYLINE CONTINUES TO PUSH EAST...AND MAY APPROACH THE OKLAHOMA
BORDER WITH THE TEXAS PANHANDLE BY 230 PM.
SCATTERED STRONG AND SEVERE THUNDERSTORMS ARE EXPECTED TO DEVELOP
QUICKLY THIS AFTERNOON... MAINLY AFFECTING CENTRAL AND EASTERN
OKLAHOMA. ISOLATED SEVERE STORMS WILL ALSO BE POSSIBLE ACROSS
WESTERN OKLAHOMA AND WESTERN NORTH TEXAS.

AREA WEATHER UPDATE
NATIONAL WEATHER SERVICE NORMAN OK
139 PM CDT MON MAY 10 2010

...WARNING DECISION UPDATE...

THIS WARNING DECISION UPDATE CONCERNS CENTRAL AND WESTERN OKLAHOMA.

TORNADO THREAT RAPIDLY INCREASING

THE ENVIRONMENT CONTINUES TO MODIFY VERY RAPIDLY ACROSS WESTERN AND
CENTRAL OKLAHOMA. BY MID AFTERNOON EXPECT CAPE VALUES AT OR ABOVE
4000 ACROSS A WIDE AREA...WITH 0-1 KM SHEAR NEAR 40 KTS. ONCE
STORMS INITIATE...THIS ENVIRONMENT WILL FAVOR A RAPID EVOLUTION TO
SUPERCELL STORMS WITH A SUBSTATIAL RISK FOR STRONG-VIOLENT
LONG-TRACK TORNADOES... ESPECIALLY CENTRAL AND PARTS OF NORTHERN
OKLAHOMA. RAPIDLY GROWING AND DEEPENING CUMULUS ALONG THE DRYLINE
SUGGEST INITIATION IS NOT FAR AWAY.

GIVEN EXPECTED STORM MOTION TOWARD EAST-NORTHEAST AT 50 MPH...WE
PLAN TO ISSUE LONG (LENGTH) POLYGONS...WITH A PREDISPOSITION TOWARD
TORNADO WARNINGS IF MESOCYCLONE DEVELOPMENT IS DETECTED.

EXPECTED TIMING OF STORMS WILL PLACE THEM INTO THE OKC METRO AND
I-35 CORRIDOR AROUND RUSH HOUR WHICH WILL MAKE THE SITUATION EVEN
MORE DANGEROUS.

.REGIONAL WEATHER DISCUSSION...
AT 345 PM...ISOLATED SEVERE THUNDERSTORMS WERE MOVING THROUGH PARTS
OF FAR NORTH CENTRAL OKLAHOMA. THESE STORMS WERE ALONG OR JUST AHEAD
OF A DRYLINE THAT STRETCHED FROM NEAR ALVA...TO CLINTON...TO
HOBART...TO KNOX CITY TEXAS.

THUS FAR STORM DEVELOPMENT AT POINTS SOUTH OF WATONGA OKLAHOMA HAS
BEEN LIMITED BY A LAYER OF WARM AIR ALOFT CALLED A CAPPING
INVERSION. HOWEVER...RECENT SATELLITE TRENDS AND RAPID UPDATE...HIGH
RESOLUTION SHORT TERM COMPUTER MODELS SUGGEST THAT EXPLOSIVE
THUNDERSTORM DEVELOPMENT WILL BE INCREASINGLY PROBABLE SOUTH ALONG
THE DRYLINE BY 4 TO 5 PM.

AS STORMS MOVE INTO CENTRAL OKLAHOMA CLOSER TO THE RUSH HOUR...THEY
WILL BE ENTERING AN ENVIRONMENT EXTREMELY SUPPORTIVE OF SUPERCELLS
THAT COULD PRODUCE VERY LARGE HAIL AND STRONG TORNADOES. STORM
MOTIONS WILL BE VERY FAST...SO ACT QUICKLY IF A WARNING IS ISSUED
FOR YOUR LOCATION AS THESE STORMS WILL BE DANGEROUS.

AREA WEATHER UPDATE
NATIONAL WEATHER SERVICE NORMAN OK
403 PM CDT MON MAY 10 2010

...WARNING DECISION UPDATE...

THIS WARNING DECISION UPDATE CONCERNS CENTRAL OKLAHOMA.

TORNADO OUTBREAK UNFOLDING.

STORMS IN NORTHERN OKLAHOMA HAVE BECOME TORNADIC AS THEY ENCOUNTERED
LOWER LIFTED CONDENSATION LEVELS AND BACKED LOW-LEVEL FLOW. EXPECT
OTHER STORMS FURTHER SOUTH AND WEST TO RAPIDLY INTENSIFY LATE THIS
AFTERNOON. LARGE HAIL AND DAMAGING WINDS WILL BE MAIN THREATS FROM
THOSE STORMS UNTIL THEY REACH CENTRAL OKLAHOMA WHERE VERY HIGH CAPE,
SHEAR, AND LOW LIFTED CONDENSATION LEVELS WILL ALLOW THEM TO
TRANSITION TO TORNADO PRODUCTION.

NEW ECHOES NORTH OF WICHITA MOUNTAINS SHOULD INTENSIFY AND POSE A
TORNADO THREAT TO OKC METRO AREA.

ONE OF THE MORE DANGEROUS SITUATIONS WE'VE SEEN IN A WHILE.

THE ENVIRONMENT OVER CENTRAL OKLAHOMA IS EXTREMELY FAVORABLE FOR
SIGNIFICANT TORNADIC SUPERCELLS...AND AS STORMS MOVE INTO THE AREA
LATE THIS AFTERNOON AND THIS EVENING THEY COULD PRODUCE STRONG
TORNADOES AND GIANT HAIL.

SCATTERED SUPERCELL THUNDERSTORMS WERE DEVELOPING ALONG AND AHEAD OF
A DRYLINE IN CENTRAL OKLAHOMA...AND EVEN DOWN INTO WESTERN NORTH
TEXAS. THESE THUNDERSTORMS WERE GENERALLY MOVING RAPIDLY TO THE
NORTHEAST OVER 50 MPH.

THIS IS A VERY DANGEROUS SITUATION. PERSONS IN CENTRAL OKLAHOMA AND
WESTERN NORTH TEXAS SHOULD BE AT A HIGH STATE OF ALERT...AND BE
PREPARED TO ACT CALMLY AND QUICKLY IF A WARNING IS ISSUED FOR THEIR
LOCATION. STORM MOTIONS WILL BE VERY FAST...SO WAITING FOR VISUAL
CLUES TO SEEK SHELTER MAY CAUSE YOU TO REACT TOO SLOWLY.

.REGIONAL WEATHER DISCUSSION...

...DANGEROUS SEVERE WEATHER OUTBREAK UNFOLDING ACROSS OKLAHOMA...

THE ENVIRONMENT OVER CENTRAL OKLAHOMA IS EXTREMELY FAVORABLE FOR
SIGNIFICANT TORNADIC SUPERCELLS...AND AS STORMS MOVE INTO THE AREA
LATE THIS AFTERNOON AND THIS EVENING THEY COULD PRODUCE STRONG
TORNADOES AND GIANT HAIL.

SCATTERED SUPERCELL THUNDERSTORMS WERE DEVELOPING ALONG AND AHEAD OF
A DRYLINE IN CENTRAL OKLAHOMA...AND EVEN DOWN INTO WESTERN NORTH
TEXAS. THESE THUNDERSTORMS WERE GENERALLY MOVING RAPIDLY TO THE
NORTHEAST OVER 50 MPH.

THIS IS A VERY DANGEROUS SITUATION. PERSONS IN CENTRAL OKLAHOMA AND
WESTERN NORTH TEXAS SHOULD BE AT A HIGH STATE OF ALERT...AND BE
PREPARED TO ACT CALMLY AND QUICKLY IF A WARNING IS ISSUED FOR THEIR
LOCATION. STORM MOTIONS WILL BE VERY FAST...SO WAITING FOR VISUAL
CLUES TO SEEK SHELTER MAY CAUSE YOU TO REACT TOO SLOWLY.

.REGIONAL WEATHER DISCUSSION...

...EXTREMELY DANGEROUS TORNADO OUTBREAK UNFOLDING ACROSS OKLAHOMA...

THE ENVIRONMENT OVER CENTRAL AND SOUTH CENTRAL OKLAHOMA REMAINS
EXTREMELY FAVORABLE FOR SIGNIFICANT TORNADIC SUPERCELLS...AND AS
STORMS CONTINUE TO MOVE ACROSS THE AREA THIS EVENING THEY COULD
PRODUCE STRONG TORNADOES AND GIANT HAIL.

SCATTERED SUPERCELL THUNDERSTORMS WERE MOVING ACROSS PARTS OF
CENTRAL OKLAHOMA. THESE THUNDERSTORMS WERE GENERALLY MOVING RAPIDLY
TO THE NORTHEAST OVER 50 MPH.

HOWEVER...REDEVELOPMENT WAS OCCURRING BEHIND THE INITIAL ROUND OF
THUNDERSTORMS...AND SOME OF THESE STORMS WERE ALSO BECOMING SEVERE.
PAY ATTENTION TO THE LATEST INFORMATION AND DO NOT LET YOUR GUARD
DOWN IF YOU ARE EAST OF A LINE FROM NEWKIRK...TO OKLAHOMA CITY...TO
WALTERS.

THIS IS AN EXTREMELY DANGEROUS SITUATION. PERSONS IN CENTRAL
OKLAHOMA SHOULD BE AT A HIGH STATE OF ALERT...AND BE PREPARED TO ACT
CALMLY AND QUICKLY IF A WARNING IS ISSUED FOR THEIR LOCATION. STORM
MOTIONS WILL BE VERY FAST...SO WAITING FOR VISUAL CLUES TO SEEK
SHELTER MAY CAUSE YOU TO REACT TOO SLOWLY.

.REGIONAL WEATHER DISCUSSION...

...DANGEROUS TORNADO OUTBREAK SHIFTING TO SOUTH CENTRAL OKLAHOMA...

THE ENVIRONMENT OVER SOUTH CENTRAL OKLAHOMA REMAINS EXTREMELY
FAVORABLE FOR SIGNIFICANT TORNADIC SUPERCELLS...AND AS STORMS
CONTINUE TO MOVE ACROSS THE AREA THIS EVENING THEY COULD PRODUCE
STRONG TORNADOES AND GIANT HAIL.

SCATTERED SUPERCELL THUNDERSTORMS WERE MOVING ACROSS PARTS OF SOUTH
CENTRAL OKLAHOMA. THESE THUNDERSTORMS WERE GENERALLY MOVING RAPIDLY
TO THE EAST NORTHEAST OVER 50 MPH.

HOWEVER...REDEVELOPMENT WAS OCCURRING BEHIND THE INITIAL ROUND OF
THUNDERSTORMS...AND SOME OF THESE STORMS WERE ALSO BECOMING SEVERE.
PAY ATTENTION TO THE LATEST INFORMATION AND DO NOT LET YOUR GUARD
DOWN IF YOU ARE EAST OF A LINE FROM SHAWNEE OKLAHOMA TO HENRIETTA
TEXAS.

THIS IS AN EXTREMELY DANGEROUS SITUATION. PERSONS IN SOUTH CENTRAL
OKLAHOMA SHOULD BE AT A HIGH STATE OF ALERT...AND BE PREPARED TO ACT
CALMLY AND QUICKLY IF A WARNING IS ISSUED FOR THEIR LOCATION. STORM
MOTIONS WILL BE VERY FAST...SO WAITING FOR VISUAL CLUES TO SEEK
SHELTER MAY CAUSE YOU TO REACT TOO SLOWLY.

.REGIONAL WEATHER DISCUSSION...

...DANGEROUS TORNADO OUTBREAK SHIFTING TO SOUTH CENTRAL OKLAHOMA...

THE ENVIRONMENT OVER SOUTH CENTRAL OKLAHOMA REMAINS EXTREMELY
FAVORABLE FOR SIGNIFICANT TORNADIC SUPERCELLS...AND AS STORMS
CONTINUE TO MOVE ACROSS THE AREA THIS EVENING THEY COULD PRODUCE
STRONG TORNADOES AND GIANT HAIL.

SCATTERED SUPERCELL THUNDERSTORMS WERE MOVING ACROSS PARTS OF
CENTRAL AND SOUTH CENTRAL OKLAHOMA. THESE THUNDERSTORMS WERE
GENERALLY MOVING RAPIDLY TO THE EAST NORTHEAST OVER 50 MPH.

HOWEVER...REDEVELOPMENT WAS OCCURRING BEHIND THE INITIAL ROUND OF
THUNDERSTORMS...AND MANY OF THESE STORMS WERE SEVERE AND TORNADIC.
PAY ATTENTION TO THE LATEST INFORMATION AND DO NOT LET YOUR GUARD
DOWN IF YOU ARE EAST OF A LINE FROM CALVIN...SOUTHWEST THROUGH
SULPHUR...AND OSCAR..

THIS IS AN EXTREMELY DANGEROUS SITUATION. PERSONS IN SOUTH CENTRAL
AND PARTS OF CENTRAL OKLAHOMA SHOULD BE AT A HIGH STATE OF
ALERT...AND BE PREPARED TO ACT CALMLY AND QUICKLY IF A WARNING IS
ISSUED FOR THEIR LOCATION. STORM MOTIONS WILL BE VERY FAST...SO
WAITING FOR VISUAL CLUES TO SEEK SHELTER MAY CAUSE YOU TO REACT TOO
SLOWLY.

LOW OVER THE ROCKIES EJECTS NORTHEASTWARD AND FRONT BEGINS TO SURGE
BACK SOUTHWARD. BROAD UPPER TROUGH WILL REMAIN TO THE WEST THROUGH
THE REMAINDER OF THE WEEK. FRONTAL BOUNDARY LINGERING NEAR THE AREA
AND DISTURBANCES MOVING THROUGH THE SOUTHWEST FLOW ALOFT LEAD TO
CONTINUED PRECIP CHANCES THROUGH THE PERIOD.
