1204 PM CDT SAT APR 9 2011

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

.DAY ONE...THIS AFTERNOON AND TONIGHT...

THUNDERSTORM OUTLOOK...
THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS THIS AFTERNOON AND
TONIGHT ACROSS WESTERN OKLAHOMA AND WESTERN NORTH TEXAS.

LOCATION...
THE SLIGHT RISK INCLUDES THE AREA WEST OF A LINE FROM MEDFORD TO EL
RENO TO DUNCAN IN OKLAHOMA...CONTINUING TO HENRIETTA AND ARCHER CITY
TEXAS.

TIMING...
THE MOST LIKELY TIME FOR SEVERE STORMS WILL BE FROM 4 PM TO MIDNIGHT.

POSSIBLE IMPACTS...
DAMAGE TO AUTOMOBILES...ROOFTOPS...AND TENDER VEGETATION FROM LARGE
HAIL.

DAMAGING STRAIGHT-LINE WIND GUSTS TO 70 MPH.

TORNADOES.

RECOMMENDED ACTIONS...
STORM SPOTTER GROUPS AND EMERGENCY MANAGEMENT PERSONNEL ACROSS THE
RISK AREA SHOULD PLAN FOR THE POSSIBILITY OF SEVERE WEATHER
OPERATIONS BEGINNING AROUND 4 PM.

DISCUSSION...
A DRYLINE IN THE TEXAS PANHANDLE WILL BECOME MORE SHARPLY DEFINED AS
IT ENTERS FAR WESTERN OKLAHOMA AND FAR WESTERN NORTH TEXAS THIS
AFTERNOON. A WARM CAP LAYER WILL PREVENT THUNDERSTORMS UNTIL AT
LEAST VERY LATE AFTERNOON. THE CHANCE OF STORM DEVELOPMENT MAY BE
FURTHER DECREASED BY SOME DRYING THAT WAS TAKING PLACE WITHIN THE
GULF AIR MASS EAST OF THE DRYLINE. STILL...DEWPOINTS IN THE UPPER
50S TO LOW 60S MAY BE SUFFICIENT FOR ISOLATED THUNDERSTORM
DEVELOPMENT NEAR THE DRYLINE THIS EVENING. THE GREATEST CHANCE OF
STORMS IS NORTH OF INTERSTATE 40...WHERE A WEAK UPPER DISTURBANCE IS
FORECAST TO INTERACT WITH THE DRYLINE.

IF ANY THUNDERSTORMS DEVELOP WITHIN THE SLIGHT RISK AREA...THEIR
ENVIRONMENT WILL INCLUDE MODERATE INSTABILITY AND STRONG WIND SHEAR.
SEVERE WEATHER IS LIKELY WITH ANY MATURE THUNDERSTORM THIS EVENING.
THE MAIN HAZARD WILL BE LARGE AND DAMAGING HAIL GREATER THAN TWO
INCHES IN DIAMETER. DAMAGING WINDS ARE ALSO LIKELY...AND TORNADOES
ARE POSSIBLE.

A GREATER CHANCE OF THUNDERSTORMS WILL OCCUR REGION WIDE LATE
TONIGHT AND EARLY SUNDAY MORNING...AS AN UPPER LEVEL TROUGH
APPROACHES. ALTHOUGH INSTABILITY WILL DECREASE OVERNIGHT...SOME
STORMS MAY INTERACT WITH THE LOW LEVEL JET...TO PRODUCE DAMAGING
WINDS IN AND CLOSE TO THE SLIGHT RISK AREA.

PROBABILITY TABLE...
VALID THROUGH 1100 PM CDT SATURDAY APR 9.
PROBABILITY OF THUNDERSTORMS OCCURRING IN THE
NWS NORMAN COUNTY WARNING AREA...30 PERCENT.
PROBABILITY OF SEVERE STORMS IF STORMS OCCUR...80 PERCENT.

OTHER HAZARDOUS WEATHER...
WARM...DRY...AND BREEZY CONDITIONS... ESPECIALLY WEST OF THE
DRYLINE...WILL INCREASE THE WILDFIRE POTENTIAL AGAIN TODAY.

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

THUNDERSTORM OUTLOOK...
THE DRYLINE WILL SURGE EASTWARD ON SUNDAY...PLACING A SLIGHT RISK OF
SEVERE STORMS IN PARTS OF SOUTH CENTRAL AND SOUTHEAST OKLAHOMA.
LARGE HAIL AND STRONG WINDS WILL BE POSSIBLE WITH ANY SEVERE STORMS
SUNDAY.

THERE WILL BE ANOTHER CHANCE FOR STORMS AROUND THE MIDDLE OF NEXT
WEEK.

OTHER HAZARDOUS WEATHER...
WITH THE DRYLINE SURGING ON SUNDAY...VERY DRY...STRONG...AND GUSTY
SOUTHWEST WINDS WILL OVERTAKE MOST OF OKLAHOMA AND WESTERN NORTH
TEXAS. THIS WILL CREATE HAZARDOUS CONDITIONS FOR OUTDOOR ACTIVITIES
AND TRAVEL...AS WELL AS PROMOTING AN EXTREME RISK OF FIRE GROWTH.
PEOPLE SHOULD TAKE CARE TO AVOID STARTING FIRES ON SUNDAY...AND
LISTEN TO WEATHER RADIO AND LOCAL NEWS FOR WEATHER UPDATES.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NORMAN OK
257 PM CDT SAT APR 9 2011

.DISCUSSION...
MAIN ISSUE THIS AFTERNOON IS GETTING SUNDAY'S HEADLINES IN ORDER.
WE WILL UP THE FIRE WEATHER WATCH TO A RED FLAG WARNING AND ADD
SEMINOLE/PONTOTOC COUNTIES TO SMOOTH OUT THE EDGE. NORMALLY WE
WOULD PREFER TO AVOID HAVING 2 RED FLAG WARNINGS OUT
SIMULTANEOUSLY... BUT GIVEN THE RELATIVE HIGH-END NATURE OF
TOMORROW'S EVENT WE WILL GO AHEAD AND RAISE THE ANTE. WE ALSO WILL
INITIATE A WIND ADVISORY FOR AREAS NEAR AND NW OF I-44 WHERE WE
ARE COMING UP WITH 30-35KT SUSTAINED. MODELS OFTEN UNDERESTIMATE
POST-DRYLINE SW WINDS... ESPECIALLY WHEN THE DRYLINE PUNCH IS
EARLY LIKE IT WILL BE ON SUNDAY. WE ALSO HAVE ADDED AREAS OF
BLOWING DUST TO MUCH OF THE CWA SUNDAY AFTERNOON... WHICH MAY
INCLUDE SMOKE. TEMPERATURES THROUGH MONDAY NIGHT ARE A BLEND OF
PERSISTENCE AND CONTINUITY WITH NEIGHBORING GRIDS. BIAS-CORRECTED
MET WORKS WELL IN MOST OF THE TMIN/TMAX GRIDS.

PRECIP POTENTIAL REMAINS LOW BUT NONZERO. STILL A LOW CHANCE OF
STORM INITIATION LATE THIS AFTERNOON OR THIS EVENING. HRRR HAS
BEEN MORE CONSISTENT FROM RUN TO RUN... AT LEAST RELATIVE TO
YESTERDAY... AND HAS INDICATED INITIATION GENERALLY OVER NW
QUADRANT OF OK AROUND 22-00Z... BUT 17Z RUN WAS THE FIRST ONE TODAY
TO SHOW NO EVENING STORMS. HOWEVER IT DOES INITIATE A FEW STORMS
OVER OUR TX ZONES AFTER 06Z... WHICH IS SUPPORTED BY THE GFS. WE
WILL MAINTAIN A BROAD STRIPE OF 20 POPS TO COVER BOTH THE
POSSIBILITY OF LATE-DAY OR EVENING INITIATION AND LATE-NIGHT
INITIATION AS LARGE-SCALE FORCING INCREASES AND DRYLINE BEGINS TO
MOVE E. CONVECTIVE POTENTIAL SUNDAY NOW APPEARS TO BE LIMITED TO
OUR FAR SE ZONES LATE IN THE DAY OR EARLY EVENING.

EXTENDED IS BASED ON STANDARD INITIALIZATION. ANOTHER LOW CHANCE
OF PRECIP AROUND THU. ACTUALLY THE CHANCES CURRENTLY LOOK GOOD
WITH AN AMPLIFYING TROUGH OVER THE AREA... BUT RECENT TRENDS AS
EVENTS DRAW CLOSER IS DPOP/DT>>0 SO WE WILL HOLD IT AT MOSTLY
SLIGHT CHANCE FOR NOW.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NORMAN OK
327 AM CDT SUN APR 10 2011

.DISCUSSION...
THE DRYLINE HAS RETREATED WEST INTO THE EASTERN TX PANHANDLE EARLY
THIS MORNING BUT WILL BEGIN MOVING BACK EAST INTO OK AND WESTERN
N-TX LATER THIS MORNING AS WINDS IN FAR WEST TEXAS HAVE BEGUN TO
VEER. MODELS ARE GENERALLY SIMILAR IN PUSHING DRYLINE FAIRLY
QUICKLY EAST INTO WESTERN AND CENTRAL OK... AND NORTH TX... THIS
MORNING BEFORE SLOWING ITS PROGRESS IN THE AFTERNOON. THIS SHOULD
LEAVE SOME OF OUR SOUTHEAST COUNTIES IN THE MOIST AIR... AND THUS
STILL WITH A POSSIBILITY OF A FEW STORMS THIS AFTERNOON AND
TONIGHT. MEANWHILE A COLD FRONT IS FORECAST TO MOVE INTO NW OK
AROUND 00Z AND EVENTUALLY OVERTAKE THE DRYLINE IN SE OK LATE
TONIGHT OR EARLY MONDAY.

TODAY CONTINUES TO BE SHAPING UP AS A SIGNIFICANT FIRE WEATHER
DAY BEHIND THE DRYLINE AS LOW HUMIDITIES AND STRONG WINDS DEVELOP.
WHILE TEMPERATURES WILL NOT BE QUITE AS WARM TODAY... THEY WILL
STILL BE SEVERAL DEGREES ABOVE AVERAGE IN MOST AREAS. STRONG WINDS
CONTINUE TO BE FORECAST AT THE MID AND UPPER LEVELS... WITH OVER
60KTS AT 700 MB AND 90 KTS AT 500 MB. DEEP MIXING WILL HELP TO
TRANSPORT SOME OF THIS HIGH-MOMENTUM AIR TO THE LOWER LEVELS
DURING THE DAY. WE WILL CONTINUE THE CURRENT RED FLAG WARNING AND
WIND ADVISORY FOR TODAY AND INTO THIS EVENING... ALTHOUGH WILL
START THE WIND ADVISORY A LITTLE EARLIER THIS MORNING DUE TO
PROFILERS INDICATING OVER 60 KTS AT 850 MB. THOUGH STILL BREEZY...
WINDS WILL NOT BE AS STRONG ON TUESDAY.

LOOKING FARTHER INTO THE WEEK... A SERIES OF UPPER WAVES MOVING
THROUGH THE SOUTHERN PLAINS WEDNESDAY NIGHT THROUGH THURSDAY MAY
RESULT IN A FEW SHOWERS AND T-STORMS. HOWEVER... THE MORE RECENT MODEL
RUNS HAS BEEN BACKING OFF ON THE WESTWARD EXTENT OF THE QPF
FIELDS... PLACING THEM MAINLY IN THE EASTERN PART OF THE CWA. THIS
TREND HAS BEEN ALL TO FAMILIAR OVER THE PAST SEVERAL WEEKS AND SEE
NO REASON TO WHY THESE SYSTEMS WILL BE ANY DIFFERENT AS THE BETTER
ENERGY/FORCING WILL AGAIN BE NORTH OF THE AREA.

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 SLIGHT RISK OF SEVERE THUNDERSTORMS LATE THIS AFTERNOON
AND EARLY THIS EVENING ACROSS SOUTHEAST OKLAHOMA.

LOCATION...
THE SLIGHT RISK INCLUDES THE AREA ALONG AND EAST OF A LINE FROM
COALGATE... TO TISHOMINGO AND MADILL.

TIMING...
THE MOST LIKELY TIME FOR SEVERE STORMS WILL BE FROM 3 PM TO 10 PM.

POSSIBLE IMPACTS...
DAMAGE TO AUTOMOBILES...ROOFTOPS...AND TENDER VEGETATION FROM HAIL
TO THE SIZE OF TENNIS BALLS.

DAMAGING STRAIGHT-LINE WIND GUSTS TO 70 MPH.

RECOMMENDED ACTIONS...
STORM SPOTTER GROUPS AND EMERGENCY MANAGEMENT PERSONNEL ACROSS THE
RISK AREA SHOULD PLAN FOR THE POSSIBILITY OF SEVERE WEATHER
OPERATIONS LATE THIS AFTERNOON INTO EARLY THIS EVENING.

DISCUSSION...
A DRYLINE WILL MOVE EAST ACROSS THE REGION TODAY. EAST OF THE
DRYLINE... MOIST AIR WILL STAY IN PLACE OVER SOUTHEAST OKLAHOMA
TODAY. AN UPPER LEVEL TROUGH WILL ALSO APPROACH THE PLAINS TODAY.
LIFT ASSOCIATED WITH THE TROUGH AND CONVERGENCE ALONG THE DRYLINE
COULD BE SUFFICIENT TO PROVIDE ENOUGH LIFT FOR THUNDERSTORMS TO
DEVELOP. MODERATE INSTABILITY AND STRONG WIND SHEAR IS EXPECTED TO
DEVELOP IN THE AIRMASS EAST OF THE DRYLINE THIS AFTERNOON. SO IF
STORMS DEVELOP... SOME OF THE STORMS COULD BECOME SEVERE PRODUCING
LARGE HAIL AND STRONG WINDS.

THUNDERSTORM CHANCES WILL CONTINUE IN SOUTHEAST OKLAHOMA TONIGHT
UNTIL A COLD FRONT OVERTAKES THE DRYLINE. HOWEVER... THE POTENTIAL
FOR SEVERE STORMS WILL DECREASE LATER THIS EVENING.

PROBABILITY TABLE...
VALID THROUGH 700 AM CDT MONDAY APR 11.
PROBABILITY OF THUNDERSTORMS OCCURRING IN THE
NWS NORMAN COUNTY WARNING AREA...30 PERCENT.
PROBABILITY OF SEVERE STORMS IF STORMS OCCUR...80 PERCENT.

OTHER HAZARDOUS WEATHER...
WARM... VERY DRY...AND VERY WINDY CONDITIONS WILL SPREAD ACROSS MUCH
OF THE WESTERN HALF TO TWO-THIRDS OF OKLAHOMA AND ALL OF WESTERN
NORTH TEXAS CREATING EXTREME WILDFIRE POTENTIAL TODAY INTO THIS
EVENING. THIS WILL CREATE HAZARDOUS CONDITIONS FOR OUTDOOR
ACTIVITIES AND TRAVEL...AS WELL AS PROMOTING AN EXTREME RISK OF FIRE
GROWTH. PEOPLE SHOULD TAKE CARE TO AVOID STARTING FIRES...AND LISTEN
TO WEATHER RADIO AND LOCAL NEWS FOR WEATHER UPDATES. A WIND SHIFT
WITH THE COLD FRONT WILL MAKING THE FIGHTING OF ANY ONGOING FIRES
DIFFICULT.

IN ADDITION TO THE FIRE CONCERNS... WINDS GUSTING OVER 50 MPH WILL
BE POSSIBLE ACROSS PARTS OF WESTERN... NORTHERN... AND CENTRAL
OKLAHOMA... AND WESTERN NORTH TEXAS TODAY. PLEASE REFER TO THE
LATEST WIND ADVISORY FOR MORE INFORMATION.

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

THUNDERSTORM OUTLOOK...
THERE WILL BE ANOTHER CHANCE FOR STORMS AROUND THE MIDDLE OF THE
WEEK.

OTHER HAZARDOUS WEATHER...
VERY HIGH TO EXTREME FIRE WEATHER CONDITIONS WILL PERSIST THROUGH
MUCH OF THE WEEK.

A DRYLINE...MERGED WITH A PACIFIC COLD FRONT...WILL MOVE QUICKLY
INTO SOUTHEAST OKLAHOMA THIS AFTERNOON...BUT THEN MOVE MORE
SLOWLY...AS AN UPPER LEVEL TROUGH APPROACHES FROM THE WEST. EAST OF
THE DRYLINE...MODERATE INSTABILITY WILL BE REALIZED IF STORMS CAN
DEVELOP THROUGH A WARM CAP LAYER ALOFT. LIFT ASSOCIATED WITH THE
TROUGH AND CONVERGENCE ALONG THE DRYLINE COULD BE SUFFICIENT TO
GENERATE A BROKEN LINE OF THUNDERSTORMS IN NORTHEAST OKLAHOMA THIS
AFTERNOON...AND THE STORMS WILL ATTEMPT TO BACK BUILD TOWARD
SOUTHEAST OKLAHOMA BY LATE AFTERNOON AND EARLY EVENING. ANY STORMS
THAT DO DEVELOP...WILL CARRY A THREAT OF DAMAGING WINDS...AND LARGE
HAIL UP TO TWO INCHES IN DIAMETER.

THE PACIFIC FRONT MAY STALL IN SOUTHEAST OKLAHOMA TONIGHT AS
ADDITIONAL UPPER LEVEL DISTURBANCES TRAVEL NORTHEAST ALONG THE
FRONT. THIS WILL MAINTAIN A LOW CHANCE OF THUNDERSTORMS THROUGH MUCH
OF THE NIGHT...BUT THE RISK OF SEVERE WEATHER SHOULD DIMINISH BY

MAXWELL/BURKE

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NORMAN OK
246 PM CDT SUN APR 10 2011

.DISCUSSION...
LOW-LEVEL WINDS HAVE NOT INCREASED AS MUCH AS EXPECTED TODAY EXCEPT
IN NW OK. LATEST MODEL WIND FORECASTS IN LOWEST 2 KM SUPPORT
MAINTAINING THE WIND ADVISORY ACROSS THE NW AND FAR N... BUT WE WILL
TRIM THE S AND SE PARTS OF THE ADVISORY WITH THE AFTERNOON PACKAGE.
THIS WILL LIKELY BE A FIRST CUT... AND MORE OF IT WILL LIKELY BE
DROPPED LATER THIS AFTERNOON OR EARLY THIS EVENING. RED FLAG
CONDITIONS ALSO NOT AS EXTREME AS ANTICIPATED EXCEPT IN THE NW...
AND WITH WINDS NOT AS STRONG WE MAY NOT HIT RED FLAG CRITERIA AT ALL
ACROSS N TX AND S/CENTRAL OK. BUT FIRE WX CONDITIONS REMAIN BAD DUE
TO VERY DRY AIR /RH BELOW 20PCT NOW OVER MOST OF THE WARNING AREA/.
WE THINK IT WOULD BE THE WRONG MESSAGE TO CANCEL THE RED FLAG
WARNING DURING WHAT AMOUNTS TO PEAK HEATING... AND SO WE WILL LEAVE
IT INTACT FOR NOW. SPEEDS MAY DROP OFF QUICKLY EVEN IN NW OK AFTER
SUNSET... BUT SHIFTING WINDS WITH SECONDARY COLD FRONT WILL MAINTAIN
FIRE CONTAINMENT CONCERNS.

CONVECTIVE POTENTIAL LOOKS HIGH THIS EVENING IN OUR SE. LATEST
HRRR AND OUN-WRF TRENDS SUGGEST INITIATION 00-03Z... IN TX ALONG
FRONT/DRYLINE AND FROM NE OK TO MO... WITH SUBSEQUENT FILLING IN
ACROSS SCENTRAL/SE OK 03-05Z. ALTHOUGH DEEP-LAYER SHEAR WILL
SUPPORT ORGANIZED STRONG CONVECTION... INSTABILITY APPEARS LIMITED
THIS FAR S WHICH WOULD LIMIT THE POTENTIAL FOR WIDESPREAD OR
SIGNIFICANT SEVERE IN SE OK.

REST OF THE FORECAST FEATURES ANOTHER LOW-END CHANCE OF
SHOWERS/STORMS WED NIGHT-THU AS A FAST-MOVING UPPER TROUGH PUNCHES E
INTO THE PLAINS... OTHERWISE IT LOOKS DRY. ECMWF IS WETTER ON
DAY7/SUNDAY BUT IT USUALLY IS... AND THUS USUALLY ENDS UP WRONG. WE
WILL WATCH IT BUT ARE NOT READY TO INTRODUCE POPS AT THIS TIME.
TEMPS ARE BASED ON STANDARD INITIALIZATION WITH A FEW ADJUSTMENTS
TO MESH BETTER WITH NEIGHBORING GRIDS.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NORMAN OK
411 AM CDT MON APR 11 2011

.DISCUSSION...
LINGERING SHOWERS AND A FEW T-STORMS OVER THE SOUTHEAST PART OF
THE CWA ARE EXPECTED TO MOVE OUT OF THE AREA OVER THE NEXT HOUR
OR SO. WE WILL COVER THIS ACTIVITY WITH SHORT TERM STATEMENTS AND
START OUT DRY IN THE 12Z FORECAST GRIDS. MEANWHILE... A COLD FRONT
WILL CONTINUE TO MOVE THROUGH THE REMAINDER OF SE OK THIS MORNING
WITH MODERATE NORTHERLY WINDS OCCURRING BEHIND IT THROUGH THE DAY.
WHILE TEMPERATURES WILL BE ABOUT 10 DEGREES COOLER TODAY THEY WILL
STILL BE NEAR OR SLIGHTLY ABOVE AVERAGE. CLOUD COVER OVER THE REGION
WILL DECREASE FROM WEST TO EAST DURING THE MORNING AS THE UPPER
LEVEL TROUGH AXIS SHIFTS EAST TOWARDS ARKANSAS.

THE GUSTY NORTH WINDS WILL DIMINISH QUICKLY BY EARLY EVENING.
LIGHT WINDS AND MOSTLY CLEAR SKIES WILL RESULT IN COOLER
TEMPERATURES OVERNIGHT. OUTSIDE OF THE SHOWERS IN THE SE EARLY
THIS MORNING... RAIN CHANCES WILL BE SMALL INTO THE MIDDLE OF THE
WEEK AS RIDGING ALOFT DOMINATES THE FLOW. FIRE WEATHER CONCERNS
WILL INCREASE SOMEWHAT IN THE WEST BY TUESDAY AFTERNOON WHICH MAY
REQUIRE A WATCH OR WARNING IF PARAMETERS INCREASE BEYOND CURRENT
EXPECTATIONS.

IN THE LONGER TERM... LOW CHANCES FOR RAIN WILL RE-ENTER THE
FORECAST FOR WEDNESDAY NIGHT AND THURSDAY IN RESPONSE TO A SERIES
OF LOW AMPLITUDE SHORT WAVES... AND A SURFACE FRONT... THAT MOVE
ACROSS THE AREA. ONCE AGAIN IT LOOKS LIKE THE PCPN CHANCES WILL
BE LIMITED TO MAINLY NEAR AND EAST OF I-35. MILD AFTERNOON
TEMPERATURES AND COOL NIGHTS ARE EXPECTED DURING THE SECOND HALF
OF THE WEEK AS HIGH PRESSURE BUILDS SOUTH INTO THE REGION ON THE
WEST SIDE OF PRESSURE SYSTEM THAT DEEPENS TO THE NORTHEAST OF THE
AREA.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NORMAN OK
332 PM CDT MON APR 11 2011

.DISCUSSION...
WINDS WILL DECREASE QUICKLY LATE THIS AFTN AND THIS EVENING AS COOL
SFC HIGH SETTLES OVER THE AREA. SOUTH WINDS RETURN QUICKLY ON TUE
WITH WARMER TEMPS AND CONT OF DRY CONDITIONS. THERE IS SOME FIRE WX
CONCERNS AGAIN ON TUESDAY... ESPECIALLY ACROSS FAR WESTERN OK WHERE
WINDS WILL BE PICK UP QUICKER AND BE STRONGER. WILL ISSUE FIRE
WEATHER WATCH FOR A FEW COUNTIES FOR TUE AFTN.

STILL WATCHING STORM SYSTEM APPROACHING THE CENTRAL AND SOUTHERN
PLAINS LATE WED INTO THU AND WILL MAINTAIN SOME LOW POPS... BUT
AGAIN TRENDS ARE INDICATING BETTER RAIN CHANCES REMAINING TO OUR
NORTH AND EAST. OTHERWISE... FIRE WX CONCERNS WILL CONT BOTH WED AND
THU AS MOISTURE WILL BE SLOW TO RETURN AHEAD OF THIS SYSTEM AND
DRYLINE WILL PUSH EAST THROUGH MUCH OF THE AREA QUICKLY ON THU.
WHICH SHOULD ALLOW DEEPER MIXING AND THEREFORE SOME STRONGER WINDS
TO MIX TO THE SFC.

COOLER AIRMASS THEN SLIDES SOUTH ON BACK SIDE OF THIS SYSTEM INTO
THE WEEKEND. ANOTHER WEAK FRONT APPROACHES BY LATE IN THE WEEKEND
WITH ANOTHER LOW-END CHANCE OF RAIN. AS HAS BEEN THE CASE FOR THE
PAST SEVERAL WEEKS... MODELS SHOW ANOTHER STORM SYSTEM AND BETTER
RAIN CHANCES BY EARLY NEXT WEEK.. BUT WILL TRY NOT TO GET TOO OVERLY
OPTIMISTIC YET AND MAIN IMPACT IS JUST BEYOND CURRENT FORECAST.

.DISCUSSION...
SOUTHERLY WINDS WILL RETURN TO THE FA TODAY WITH BREEZY CONDITIONS
EXPECTED IN PARTS OF WESTERN OK THIS AFTERNOON. THESE BREEZY
CONDITIONS WILL COMBINE WITH THE DRY AIR AND WARM TEMPERATURES TO
INCREASE THE WILDFIRE POTENTIAL. WILL UPGRADE PORTIONS OF THE FIRE
WX WATCH TO A RED FLAG WARNING... PARTS OF WEST CENTRAL AND
NORTHWEST OK. WIND SPEEDS EXPECTED TO BE MARGINAL BUT STILL ABOVE
CRITERIA. ELSEWHERE... WIND SPEEDS NOT EXPECTED TO MEET CRITERIA...
HOWEVER... THE DRY AND WARM CONDITIONS WILL STILL INCREASE THE
WILDFIRE POTENTIAL.

A BOUNDARY WILL MOVE INTO WESTERN PORTIONS OF THE FA WEDNESDAY AND
WEDNESDAY NIGHT. MEANWHILE... MOISTURE WILL SPREAD NORTHWARD
ACROSS THE REGION. A FEW SHOWERS AND THUNDERSTORMS WILL BE POSSIBLE
WEDNESDAY NIGHT AS A SHORTWAVE APPROACHES THE PLAINS. THIS SYSTEM
WILL MOVE EAST ACROSS THE PLAINS THURSDAY. A DRYLINE WILL MOVE EAST
ACROSS THE REGION THURSDAY. FIRE WX MAY BECOME A CONCERN BEHIND THE
DRYLINE AND AHEAD OF A COLD FRONT THAT WILL MOVE ACROSS THE REGION
LATE THURSDAY/THURSDAY NIGHT. SHOWERS AND THUNDERSTORMS WILL ONCE
AGAIN BE POSSIBLE ALONG THE DRYLINE.

THE COOLER AIR MOVING INTO THE REGION BEHIND THE COLD FRONT WILL
KEEP HIGH TEMPERATURES AROUND OR EVEN SLIGHTLY BELOW SEASONAL
NORMALS THROUGH THE WEEKEND. LOWS FRIDAY NIGHT/SATURDAY MORNING ARE
EXPECTED TO BE COLD WITH TEMPERATURES IN NORTHERN OK POSSIBLY
DROPPING TO OR BELOW FREEZING. MODELS DIFFER BUT BOTH SHOW SHOWERS
AND THUNDERSTORMS MAY BE POSSIBLE LATE THIS WEEKEND INTO EARLY NEXT
WEEK AS SEVERAL DISTURBANCES MOVE THROUGH THE UPPER LEVEL FLOW.

SFC BOUNDARY WILL SAG INTO NW PORTIONS OF FA TODAY/TONIGHT.
MEANWHILE... MOISTURE WILL SPREAD NORTHWARD ACROSS THE REGION. WITH
INCREASING MOISTURE... WILL HOLD OFF ON ANY FIRE WX HEADLINES FOR
TODAY. HOWEVER... THE WILDFIRE POTENTIAL WILL STILL INCREASE SOME
THIS AFTERNOON... ESPECIALLY IN SW PORTIONS OF THE FA. UPPER SYSTEM
WILL MOVE ACROSS THE CENTRAL ROCKIES TONIGHT. AN ISOLATED
SHOWER/STORM CAN NOT BE RULED OUT FOR LATE TONIGHT BUT NOT ENOUGH
CHANCE FOR ANY MENTIONABLE POPS. THE UPPER SYSTEM WILL CONTINUE TO
MOVE EAST TOMORROW ACROSS THE PLAINS. MEANWHILE... A DRYLINE WILL
MOVE EAST ACROSS THE AREA. SHOWERS AND THUNDERSTORMS WILL BE
POSSIBLE ALONG THE DRYLINE IN MAINLY EASTERN PORTIONS OF THE FA.
BEHIND THE DRYLINE... LOW HUMIDITIES WILL COMBINE WITH WARM TEMPS
AND WINDY CONDITIONS TO INCREASE THE WILDFIRE POTENTIAL... SO WILL
ISSUE A FIRE WX WATCH FOR PORTIONS OF THE FA. THERE IS STILL SOME
UNCERTAINTY AS TO THE TRACK OF THE SFC LOW AND THEREFORE WHAT AREAS
WILL END UP IN THE DRIEST AIR SO CONFIGURATION OF FIRE WX CONCERNS
MAY CHANGE IN SUBSEQUENT SHIFTS.

A COLD FRONT WILL MOVE ACROSS THE FA LATE THURSDAY/THURSDAY NIGHT
BRINGING COOLER AIR TO THE REGION. GUSTY NORTH/NORTHWEST WINDS WILL
CONTINUE FRIDAY AS UPPER SYSTEM INTENSIFIES. BELOW NORMAL
TEMPERATURES EXPECTED FRIDAY. WRAP AROUND PRECIP MAY AFFECT NORTHERN
PORTIONS OF THE CWA THU NIGHT/FRI. A COLD START TO THE DAY EXPECTED
SATURDAY MORNING WITH TEMPERATURES IN THE 30S AND LOW 40S ACROSS THE

.DISCUSSION...
UPPER TROUGH ALONG WEST COAST WILL APPROACH THE SOUTHERN PLAINS
TONIGHT INTO THURSDAY. MODELS SIMILAR IN DEVELOPING CLOSED LOW
OVER KANSAS THURSDAY AFTERNOON/EVENING. MEANWHILE...FRONTAL
BOUNDARY ACROSS OK PANHANDLE/NORTHWEST OK WILL MAKE SOME PROGRESS
TO THE SOUTHEAST TODAY BUT WILL STALL TONIGHT AS SURFACE LOW
DEEPENS ACROSS TEXAS PANHANDLE.

WILDFIRE AND SEVERE STORM CONCERNS WILL INCREASE BY THURSDAY
AFTERNOON. DRYLINE IS FORECAST TO APPROACH I-35 CORRIDOR BY
20-21Z. INSTABILITY AND SHEAR WILL BE SUFFICIENT FOR SUPERCELL
STORMS WITH LARGE HAIL AND PERHAPS TORNADOES. WILL BE INTERESTING
TO SEE HOW HRRR AND LOCAL WRF HANDLE CONVECTIVE TRENDS TOMORROW.
EXTREME WILDFIRE CONDITIONS WILL DEVELOP BEHIND THE DRYLINE
THURSDAY AFTERNOON. WILL LIKELY UPGRADE THURSDAY'S FIRE WEATHER
WATCH TO A RED FLAG WARNING...ESPECIALLY ACROSS SOUTHWEST 1/4 OF
FA AND LEAVE REST AS A WATCH.

STRONG WINDS WILL DEVELOP BEHIND A COLD FRONT THURSDAY NIGHT INTO
FRIDAY. WILL LIKELY NEED A WIND ADVISORY AND A RED FLAG WARNING FOR
PARTS OF THE AREA ON FRIDAY. TEMPERATURES FOR A RED FLAG WARNING
MAY BE HARDER TO COME BY FRIDAY...BUT SOUTHERN HALF OF AREA SHOULD
REACH UPPER 60S TO LOWER 70S.

WINDS WILL DIMINISH QUICKLY FRIDAY EVENING/NIGHT. THIS WILL ALLOW
TEMPS TO APPROACH THE FREEZING MARK BY SATURDAY MORNING.
NORTHERN AND PARTS OF WESTERN OK MAY BE MORE LIKELY TO SEE
FREEZING TEMPS SAT AM.

THUNDERSTORM OUTLOOK...
THE CHANCE OF THUNDERSTORMS IS VERY LOW THROUGH TONIGHT.

DISCUSSION...
A LOW LEVEL JET WILL BEGIN TO PULL GULF MOISTURE UP INTO NORTH TEXAS
AND SOUTHERN OKLAHOMA BY LATE TONIGHT. GIVEN WARM TEMPERATURES
ALOFT...IT WILL BE DIFFICULT FOR THE INITIAL MOISTURE RETURN TO
PRODUCE RAIN. IF ANY SHOWERS OR THUNDERSTORMS DO OCCUR...INSTABILITY
WILL BE VERY LIMITED...RESULTING IN ONLY BRIEF RAIN AND PERHAPS A
FEW LIGHTNING STRIKES.

PROBABILITY TABLE...
VALID THROUGH 700 AM CDT THURSDAY APR 14.
PROBABILITY OF THUNDERSTORMS OCCURRING IN THE

OTHER HAZARDOUS WEATHER...
NONE.

.DAYS TWO THROUGH SEVEN...THURSDAY THROUGH TUESDAY...

THUNDERSTORM OUTLOOK...
THERE IS A SLIGHT TO MODERATE RISK OF SEVERE THUNDERSTORMS THURSDAY
AFTERNOON AND EARLY EVENING. THE SLIGHT RISK AREA IS EAST OF A LINE
FROM MEDFORD TO JONES TO MADILL. THE MODERATE RISK AREA IS EAST OF A
LINE FROM NEWKIRK TO CUSHING...TO ADA AND ATOKA. A SEASONALLY STRONG
JET STREAM WILL EJECT FROM THE ROCKIES...CAUSING LOW PRESSURE TO
INTENSIFY IN SOUTHERN KANSAS...AND DRAGGING A DRYLINE TO THE WESTERN
BORDER OF THE SLIGHT RISK AREA BY MID AFTERNOON. ADEQUATE RETURN OF
GULF MOISTURE AHEAD OF THE DRYLINE...COMBINED WITH INTENSE
LIFTING...WILL RESULT IN SCATTERED STRONG TO SEVERE THUNDERSTORMS
OVER THE RISK AREA BY LATE AFTERNOON AND EARLY EVENING.

VERY STRONG WINDS AT ALL LEVELS...WILL YIELD THE DISTINCT
POSSIBILITY OF DAMAGING WINDS. LARGE HAIL AND TORNADOES ARE ALSO
POSSIBLE...ESPECIALLY OVER THE MODERATE RISK AREA. STORMS WILL MOVE
RAPIDLY EASTWARD AT 30 TO 40 MPH...SO PEOPLE SHOULD THINK AHEAD AND
REACT QUICKLY TO SEVERE WEATHER WARNINGS. THE DRYLINE MAY STALL OVER
SOUTHEAST OKLAHOMA DURING THE EVENING. THE RISK OF SEVERE WEATHER
WILL END WHEN A COLD FRONT SWEEPS THROUGH THAT REGION LATER IN THE
NIGHT.

THE NEXT CHANCE OF THUNDERSTORMS IS FORECAST FOR MONDAY AND TUESDAY
OF NEXT WEEK.

OTHER HAZARDOUS WEATHER...
FIRE WEATHER WILL BE OF GREAT CONCERN DURING WINDY WEATHER ON BOTH
THURSDAY AND FRIDAY. PLEASE REFER TO THE FIRE WEATHER MESSAGE

MID AND UPPER WAVE WILL MOVE ACROSS THE CENTRAL ROCKIES AND DEEPEN
OVER THE CENTRAL PLAINS. MEANWHILE... A SFC LOW WILL DEVELOP IN THE
TX PANHANDLE AND LIFT NORTHEAST INTO KANSAS TODAY. A DRYLINE
EXTENDING FROM THE LOW WILL MOVE EAST ACROSS THE FA. A COLD FRONT
WILL THEN MOVE SOUTH ACROSS THE REGION TONIGHT. SHOWERS AND
THUNDERSTORMS WILL BE POSSIBLE ACROSS NORTHERN AND EASTERN PARTS OF
THE FA LATER THIS AFTERNOON AND TONIGHT. INSTABILITY AND STRONG WIND
SHEAR WILL BE SUFFICIENT FOR SOME OF THE STORMS TO BECOME SEVERE.
BEHIND THE DRYLINE AND AHEAD OF THE COLD FRONT... A VERY DRY AND
GUSTY AIRMASS WILL MOVE INTO THE REGION. THE DRY AIR AND GUSTY WINDS
WILL COMBINE TO INCREASE THE WILDFIRE POTENTIAL WITH A RED FLAG
WARNING BEING ISSUED FOR PARTS OF THE FA. THE WINDS WILL ALSO BECOME
STRONG IN PARTS OF WESTERN OKLAHOMA AND NORTH TEXAS THIS AFTERNOON
SO WILL ISSUE A WIND ADVISORY.

GUSTY NORTHERLY WINDS WILL OCCUR DIRECTLY BEHIND THE COLD FRONT
TONIGHT. HOWEVER... MUCH STRONGER WINDS ARE EXPECTED LATE
TONIGHT/FRIDAY... WITH STRONG CAA BEHIND THE FRONT. WILL ISSUE A
HIGH WIND WATCH FOR APPROX WESTERN HALF OF FA WITH A WIND ADVISORY
FOR REST OF AREA EXCEPT IN THE SOUTHEAST. WINDS EXPECTED TO DECREASE
FRIDAY NIGHT AS SFC HIGH SETTLES INTO REGION AND STORM SYSTEM MOVES
AWAY FROM THE AREA. FIRE WX CONDITIONS MAY ALSO BE MET IN SW
PORTIONS OF THE FA FRIDAY AFTERNOON BUT WITH ALREADY SO MANY

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 MODERATE RISK OF SEVERE THUNDERSTORMS OVER PORTIONS OF
EAST CENTRAL AND SOUTHEAST OKLAHOMA. THERE IS ALSO A SLIGHT RISK OF
SEVERE STORMS FROM NORTH CENTRAL INTO SOUTH CENTRAL OKLAHOMA.

LOCATION...
THE MODERATE RISK AREA IS GENERALLY ALONG AND EAST OF A LINE
EXTENDING FROM CUSHING... TO ADA... TO DURANT. THE SLIGHT RISK AREA
INCLUDES THE REMAINING PORTIONS OF CENTRAL OKLAHOMA LOCATED EAST OF
A LINE EXTENDING FROM ENID... TO LINDSAY... TO HEALDTON.

TIMING...
THE MOST LIKELY TIME FOR SEVERE THUNDERSTORMS WILL BE FROM MID TO
LATE AFTERNOON THROUGH THIS EVENING.

IMPACTS...
DAMAGING WINDS TO NEAR 70 MPH... HAIL TO THE SIZE OF BASEBALLS...
AND ISOLATED TORNADOES.

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

DISCUSSION...
A STRONG UPPER LEVEL STORM SYSTEM... LOCATED NEAR THE FOUR CORNERS
AREA THIS MORNING... WILL CONTINUE MOVING EAST INTO THE CENTRAL AND
SOUTHERN PLAINS THROUGH THIS EVENING. A DRYLINE WILL BECOME
ESTABLISHED OVER THE WESTERN PORTIONS OF OKLAHOMA AND NORTH TEXAS
THIS MORNING AND THEN MOVE EAST TO NEAR THE INTERSTATE 35 CORRIDOR
BY MID TO LATE AFTERNOON. A STRONG CAPPING INVERSION WILL INITIALLY
SUPPRESS THUNDERSTORM DEVELOPMENT TODAY. HOWEVER... THE COMBINATION
OF DAYTIME HEATING... AND COOLING TEMPERATURES ALOFT ASSOCIATED WITH
AN APPROACHING UPPER STORM SYSTEM... SHOULD WEAKEN THE CAP DURING
THE AFTERNOON. SCATTERED THUNDERSTORMS ARE EXPECTED TO DEVELOP NEAR
AND AHEAD OF THE DRYLINE DURING THE MID TO LATE AFTERNOON HOURS OVER
PORTIONS OF CENTRAL OKLAHOMA AND SPREAD TO THE EAST AND NORTHEAST.

ALTHOUGH THE INSTABILITY THIS MORNING WAS MINIMAL... LOW LEVEL
MOISTURE WILL MOVE QUICKLY NORTH FROM TEXAS DURING THE DAY... AND
SUBSTANTIALLY INCREASE INSTABILITIES BY THIS AFTERNOON AHEAD OF THE
DRYLINE. MEANWHILE... STRONG UPPER LEVEL JET STREAM WINDS MOVING
INTO OKLAHOMA AND NORTH TEXAS WILL PROVIDE SUFFICIENT WIND SHEAR TO
SUPPORT DAMAGING THUNDERSTORM WINDS. VERY LARGE HAIL AND TORNADOES
WILL ALSO BE POSSIBLE... ESPECIALLY OVER THE MODERATE RISK AREA. THE
DRYLINE MAY STALL FOR A FEW HOURS OVER SOUTHEAST OKLAHOMA THIS
EVENING BEFORE BEING OVERTAKEN BY A COLD FRONT LATER TONIGHT WHICH
WILL BRING AN END TO THE SEVERE WEATHER RISK.

PROBABILITY TABLE...
VALID THROUGH 700 AM CDT FRIDAY APR 15.
PROBABILITY OF THUNDERSTORMS OCCURRING IN THE
NWS NORMAN COUNTY WARNING AREA...70 PERCENT.
PROBABILITY OF SEVERE STORMS IF STORMS OCCUR...80 PERCENT.

OTHER HAZARDOUS WEATHER...
FIRE WEATHER CONDITIONS WILL BE OF GREAT CONCERN TODAY... ESPECIALLY
BEHIND THE DRYLINE ACROSS PARTS OF WESTERN AND CENTRAL OKLAHOMA AND
WESTERN NORTH TEXAS. A RED FLAG WARNING IS IN EFFECT. STRONG WINDS
GUSTING 35 TO 45 MPH HAVE ALSO PROMPTED THE ISSUANCE OF A WIND
ADVISORY FOR THIS AFTERNOON AND EARLY THIS EVENING OVER PARTS OF
SOUTHWEST OKLAHOMA AND WESTERN NORTH TEXAS. PLEASE REFER TO THE
APPROPRIATE WARNING AND ADVISORY PRODUCTS FOR MORE DETAILS.

VERY STRONG WINDS ARE EXPECTED TO DEVELOP LATE TONIGHT BEHIND THE
COLD FRONT AS IT MOVES THROUGH OKLAHOMA AND WESTERN NORTH TEXAS. A
HIGH WIND WATCH AND A WIND ADVISORY ARE IN EFFECT FOR LATE TONIGHT.
PLEASE REFER TO THE LATEST VERSIONS OF THESE PRODUCTS FOR ADDITIONAL
DETAILS.

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

THUNDERSTORM OUTLOOK...
THERE IS A CHANCE FOR THUNDERSTORMS FROM NEXT MONDAY THROUGH
WEDNESDAY.

OTHER HAZARDOUS WEATHER...
VERY STRONG WINDS GUSTING 40 TO 50 MPH ARE EXPECTED ON FRIDAY WITH
OCCASIONALLY HIGHER GUSTS TO NEAR 60 MPH POSSIBLE IN SOME LOCATIONS.
PLEASE REFER TO THE LATEST HIGH WIND WATCH AND WIND ADVISORY
PRODUCTS FOR ADDITIONAL INFORMATION. ALTHOUGH COOLER TEMPERATURES
AND SOMEWHAT HIGHER HUMIDITIES ARE EXPECTED FOR FRIDAY... FIRE
WEATHER CONCERNS WILL REMAIN HIGH DUE TO THE EXCESSIVE WIND SPEEDS.

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

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

.DAY ONE...THIS AFTERNOON AND TONIGHT...

THUNDERSTORM OUTLOOK...
THERE IS A MODERATE RISK OF SEVERE THUNDERSTORMS OVER PORTIONS OF
EAST CENTRAL AND SOUTHEAST OKLAHOMA. THERE IS ALSO A SLIGHT RISK OF
SEVERE STORMS FROM NORTH CENTRAL INTO SOUTH CENTRAL OKLAHOMA.

LOCATION...
THE MODERATE RISK AREA IS GENERALLY ALONG AND EAST OF A LINE
EXTENDING FROM CUSHING... TO ADA... TO DURANT. THE SLIGHT RISK AREA
INCLUDES THE REMAINING PORTIONS OF CENTRAL OKLAHOMA LOCATED EAST OF
A LINE EXTENDING FROM ENID... TO LINDSAY... TO HEALDTON.

TIMING...
THE MOST LIKELY TIME FOR SEVERE THUNDERSTORMS WILL BE FROM 3 PM
THROUGH 10 PM.

IMPACTS...
DAMAGING WINDS TO NEAR 70 MPH... HAIL TO THE SIZE OF BASEBALLS...
AND ISOLATED TORNADOES.

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

DISCUSSION...
A STRONG UPPER LEVEL STORM SYSTEM WILL MOVE EAST INTO THE CENTRAL
AND SOUTHERN PLAINS THROUGH THIS EVENING. A DRYLINE WILL ADVANCE
EAST THIS AFTERNOON AND WILL APPROACH THE I-35 CORRIDOR BY
MID AFTERNOON. A STRONG CAPPING INVERSION WILL INITIALLY SUPPRESS
THUNDERSTORM DEVELOPMENT. HOWEVER... THE COMBINATION OF DAYTIME
HEATING... AND COOLING TEMPERATURES ALOFT ASSOCIATED WITH AN
APPROACHING UPPER STORM SYSTEM... SHOULD WEAKEN THE CAP DURING THE
AFTERNOON. SCATTERED THUNDERSTORMS ARE EXPECTED TO DEVELOP NEAR AND
AHEAD OF THE DRYLINE DURING THE MID TO LATE AFTERNOON HOURS.
INSTABILITY AND WIND SHEAR WILL SUPPORT SEVERE THUNDERSTORMS WITH
LARGE HAIL AND DAMAGING WIND GUSTS. TORNADOES WILL ALSO BE POSSIBLE
ESPECIALLY IN THE MODERATE RISK AREA. THE DRYLINE MAY STALL FOR A
FEW HOURS OVER SOUTHEAST OKLAHOMA THIS EVENING BEFORE BEING
OVERTAKEN BY A COLD FRONT LATER TONIGHT WHICH WILL BRING AN END TO
THE SEVERE WEATHER RISK.

PROBABILITY TABLE...
VALID THROUGH 700 AM CDT FRIDAY APR 15.
PROBABILITY OF THUNDERSTORMS OCCURRING IN THE
NWS NORMAN COUNTY WARNING AREA...70 PERCENT.
PROBABILITY OF SEVERE STORMS IF STORMS OCCUR...80 PERCENT.

OTHER HAZARDOUS WEATHER...

BEHIND THE DRYLINE ACROSS PARTS OF WESTERN AND CENTRAL OKLAHOMA AND
WESTERN NORTH TEXAS. A RED FLAG WARNING IS IN EFFECT. A WIND ADVISORY
IS ALSO IN EFFECT FOR PARTS OF SOUTHWEST OKLAHOMA AND WESTERN
NORTH TEXAS.

VERY STRONG WINDS ARE EXPECTED TO DEVELOP LATE TONIGHT BEHIND THE
COLD FRONT AS IT MOVES THROUGH OKLAHOMA AND WESTERN NORTH TEXAS. A
HIGH WIND WATCH AND A WIND ADVISORY ARE IN EFFECT FOR LATE TONIGHT.
PLEASE REFER TO THE LATEST VERSIONS OF THESE PRODUCTS FOR ADDITIONAL
DETAILS.

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

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NORMAN OK
323 PM CDT THU APR 14 2011

.DISCUSSION...
IN THE NEAR TERM...CONCERNS LIE WITH SEVERE THUNDERSTORM
DEVELOPMENT EAST OF THE DRYLINE...AND WITH ELEVATED WILDFIRE
POTENTIAL WEST OF THE DRYLINE. REGIONAL RADARS SHOW THAT THE FIRST
ECHOES HAVE ALREADY APPEARED EAST OF THE DRYLINE. WITH TIME...MID
LEVEL COOLING ASSOCIATED WITH THE CLOSED AND DEEPENING LOW...ALONG
WITH CONTINUED SURFACE HEATING...SHOULD ENCOURAGE FURTHER
DEVELOPMENT. THE PRESENT THERMODYNAMIC PROFILE IS CONDUCIVE TO
VERY LARGE HAIL...WITH A TORNADO THREAT DEVELOPING TOWARD EVENING
IN EASTERN PORTIONS OF THE CWA AS LOW LEVEL WIND FIELDS BECOME
MORE FAVORABLE.

A COLD FRONT WILL PUSH THROUGH THE CWA TONIGHT...EVENTUALLY ENDING
THE SEVERE WEATHER THREAT. HOWEVER...VERY STRONG POST FRONTAL
NORTHWEST WINDS ARE EXPECTED TO DEVELOP...WITH A HIGH WIND WATCH
AND WIND ADVISORY FOR FRIDAY LEFT UNCHANGED FROM THE PREVIOUS
FORECAST. IN ADDITION...HUMIDITY SHOULD BE LOW ENOUGH AND
TEMPERATURE HIGH ENOUGH IN SOUTHWESTERN PORTIONS OF THE CWA THAT A
FIRE WEATHER WATCH HAS BEEN ISSUED FOR FRIDAY. NORTHERN PORTIONS
OF THE CWA MAY REMAIN CLOUDY MOST OF THE DAY...WITH SOME VERY
LIGHT RAIN POSSIBLE.

WINDS WILL BECOME LIGHTER ON SATURDAY AS THE INTENSE CLOSED LOW
MOVES OFF TO THE NORTHEAST. THROUGH MONDAY...AFTERNOON HIGH TEMPERATURES
WILL WARM INTO THE 70S AND EVENTUALLY THE 80S. STRONG SOUTH WINDS
MAY DEVELOP AGAIN BY AROUND TUESDAY...WITH THE NEXT NOTABLE CHANCE
OF PRECIPITATION OCCURRING ROUGHLY AT MID-WEEK.

.REGIONAL WEATHER DISCUSSION...
AROUND 700 PM...STRONG TO SEVERE THUNDERSTORMS WERE ACROSS PORTIONS
OF SOUTH EASTERN AND SOUTH CENTRAL OKLAHOMA. THESE THUNDERSTORMS
WERE DEVELOPING AHEAD OF DRYLINE WHICH EXTENDED FROM NEAR LUTHER TO
WASHINGTON TO NEAR VELMA. THE DRYLINE HAD BECOME NEAR STATIONARY
WITH A SLIGHT REGRESSION BACK TOWARDS THE WEST. THE COLD FRONT HAD
BEGUN TO OVERTAKE THE DRYLINE ACROSS PORTIONS OF LINCOLN AND
OKLAHOMA COUNTIES IN CENTRAL OKLAHOMA. THE COLD FRONT WAS ANALYZED
ALONG AND NEAR A LINE FROM STILLWATER TO OKLAHOMA CITY TO BRIDGE
CREEK AND BACK WESTWARD TOWARDS BESSIE AND ERICK. STRONG WINDS WERE
ALSO NOTED ACROSS PORTIONS OF EXTREME SOUTHWESTERN OKLAHOMA NEAR
HOLLIS..ALTUS...AND GRANDFIELD WITH WIND GUSTS APPROACHING 35 TO 40
MPH.

THUNDERSTORMS WILL CONTINUE TO MOVE TOWARDS THE EAST
NORTHEAST INTO THE EVENING HOURS AHEAD OF THE DRYLINE. WITH STRONG
SHEAR AND SUFFICIENT INSTABILITY IN PLACE...MOST STORMS WILL BECOME
SEVERE QUICKLY AND WILL HAVE THE POTENTIAL TO PRODUCE VERY LARGE
HAIL...STRONG DAMAGING WINDS AND TORNADOES. THE COLD FRONT WILL
OVERTAKE THE DRYLINE FROM NORTH TO SOUTH AS THE EVENING PROGRESSES.
A FEW ADDITIONAL THUNDERSTORMS CANNOT BE RULED OUT AS THIS PROCESS
OCCURS. STRONG WESTERLY AND NORTHWESTERLY WINDS WILL ELEVATE THE
WILDFIRE POTENTIAL INTO THE EARLY EVENING HOURS. A FEW AREAS OF
BLOWING DUST WILL ALSO BE POSSIBLE ACROSS SOUTHWESTERN OKLAHOMA.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NORMAN OK
1006 PM CDT THU APR 14 2011

.UPDATE...EARLIER ROUND OF DAMAGING SUPERCELLS IN SOUTHEAST
OKLAHOMA HAD GIVEN WAY TO A BROKEN SQUALL LINE...AS INITIAL
PACIFIC FRONT OVERTAKES THE DRYLINE. THIS SHOULD MOVE OUT BY
MIDNIGHT OR SHORTLY THEREAFTER.

ATTENTION THEN TURNS TO THE BROAD AND DEEPENING CYCLONE OVERHEAD.
AFTER A QUICK GLANCE AT THE RUC...WE UPGRADED THE WIND WATCH TO A
HIGH WIND WARNING. CLOUD COVER IS NOT TOO MUCH OF A CONCERN FOR
LIMITING MIXING...BECAUSE THE GRADIENT ALONE WOULD SUPPORT A HIGH-
END ADVISORY...AND INDICATIONS ARE THAT CLOUD COVER WILL BE
SCATTERED OR BECOME SCATTERED DURING THE DAY FRIDAY. WE WOULD THEN
MIX INTO 0-1 KM MEAN WIND SPEEDS OF 35 TO NEAR 50 KNOTS. THE
RESULT WILL BE A POTENTIALLY DAMAGING GRADIENT WIND STORM. THOUGH
THE WARNING BEGINS AT 4 AM...WE MAY NEED TO RE-EVALUATE...AS LATE
EVENING OBSERVATIONS HAD BEGUN TO SHOW GUSTS OVER 40 MPH IN
WESTERN OKLAHOMA.

FIRE DANGER WILL ALSO BE IMPORTANT FRIDAY...ALTHOUGH PERHAPS THE
LACK OF FIRE STARTS TODAY IS SOMEWHAT INDICATIVE OF THE SPRING
GREEN-UP. ALSO...TEMPERATURES MAY BE A BIT COOLER THAN FORECAST
BASED ON CURRENT OBSERVATIONS IN WESTERN KANSAS...BUT IT WILL
STILL LIKELY BE DRY ENOUGH TO SUPPORT A RED FLAG WARNING...GIVEN
THE EXTREME NATURE OF THE WIND SPEEDS.

NATIONAL WEATHER SERVICE NORMAN OK
443 AM CDT FRI APR 15 2011

.DISCUSSION...
WIND WILL BE THE HEADLINER TODAY. GUSTS 40-55MPH/35-45KT NOW BECOMING
MORE FREQUENT OVER W OK AS INTENSE LOW OVER KS MOVES SLOWLY E. WE
WILL KEEP THE WIND HEADLINES AS IS WITH HIGH WIND WARNING W AND
WIND ADVISORY NCENTRAL/CENTRAL OK INTO N TX. FIRE WEATHER WATCH IS
UPGRADED TO A RED FLAG WARNING. MIN RH MAY NOT QUITE REACH 20PCT
CRITERION AROUND CADDO COUNTY BUT WE WILL LEAVE THE AREA INTACT...
AND IN FACT WILL ADD STEPHENS AND JEFFERSON COUNTIES IN S OK. LOW
POPS WILL BE KEPT IN FOR SOME WRAPAROUND SHOWERS INTO MAINLY
NCENTRAL OK. HIGHS HAVE BEEN LOWERED INTO THE LOW-MID 50S IN
NCENTRAL OK WHERE COLD ADVECTION AND CLOUD COVER ARE LIKELY TO
KEEP IT CHILLY. COLD NIGHT TONIGHT WITH MUCH OF THE AREA FALLING
INTO THE 30S. WINDS WILL DECREASE BUT THERE SHOULD BE ENOUGH WIND
AND SUFFICIENT LACK OF MOISTURE TO PREVENT ANY WIDESPREAD FROST OR
FREEZE CONDITIONS. FAIRLY QUICK WARMUP OVER THE WEEKEND AS
LONGWAVE PATTERN TRANSITIONS TO LOW-AMPLITUDE ZONAL FLOW... WHICH
ALSO WILL KEEP MOST OF THE AREA IN THE ALL-TOO-FAMILIAR DRY
REGIME FOR MUCH OF THE NEXT WEEK. BUT WE WILL RETAIN SOME LOW POPS
MAINLY FOR E PARTS OF THE AREA WITH LOW-AMPLITUDE SYSTEMS AROUND
MON NIGHT/TUE AND AGAIN IN ABOUT A WEEK. LONG-TERM CLIMATOLOGY
WOULD INDICATE INCREASING PRECIP CHANCES GOING INTO LATE APRIL AND
MAY... ESPECIALLY WITH INDICATIONS OF A SLOW-MOVING SURFACE FRONT
SOMEWHERE IN TX DURING MUCH OF THE LATTER HALF OF NEXT WEEK. BUT
IT STILL SEEMS PRUDENT TO KEEP THE POPS ON THE LOW SIDE UNTIL
THERE ARE STRONGER INDICATIONS OF A CHANGE TOWARD A WETTER
PATTERN.
