AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NORMAN OK
435 AM CDT THU MAY 8 2003

BUSY NIGHT HERE WITH PERSISTENT TORNADIC SUPERCELL MOVING ACROSS
SOUTHERN ZONES THIS MORNING. PRODUCTS WILL LIKELY BE DELAYED... BUT
SHOULD BE OUT BY AROUND 445 AM.

AS UPPER WAVE TRACKS NORTHEAST INTO CENTRAL PLAINS... THE SURFACE
LOW WILL BE DRAGGED NORTHEAST AND PULL DRYLINE EAST. THE WARM FRONT
IS CURRENTLY OVER NORTHERN OKLAHOMA AND CONVECTION IS NOT WIDESPREAD
ENOUGH TO HALT ITS ADVANCE. ETA MODEL FORECAST SOUNDINGS SHOW AN
UNCAPPED ATMOSPHERE DEVELOPING EVEN BY 18Z AHEAD OF THE DRYLINE SO
EXPECT THUNDERSTORMS TO REDEVELOP THIS AFTERNOON. THERE MAY BE A
BREAK IN THE ACTION ON THE BACKSIDE OF THE WAVE AFTER THIS EVENING.
DO NOT THINK DRYLINE WILL ADVANCE QUITE AS FAR AS MODELS ADVERTISE
TOMORROW WITHOUT A STRONG UPPER SYSTEM MOVING THROUGH... SO WILL
KEEP MOISTURE AND HIGHER POPS FARTHER WEST. WILL KEEP CHANCE OF
THUNDER THROUGH MOST AREAS THROUGH SATURDAY UNTIL THE MAIN UPPER
WAVE MOVES THROUGH THE AREA SATURDAY NIGHT. THEN WE MAY FINALLY SEE
A BRIEF BREAK IN THE THUNDERSTORM CHANCES.

HAZARDOUS WEATHER OUTLOOK
NATIONAL WEATHER SERVICE NORMAN OK
700 AM CDT THU MAY 8 2003

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 THROUGH TONIGHT
ACROSS PORTIONS OF OKLAHOMA AND WESTERN NORTH TEXAS.

LOCATION...
THE SLIGHT RISK AREA IS EAST OF A LINE FROM MEDFORD...TO BINGER...TO
GRANDFIELD... TO SEYMOUR TEXAS.

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

RECOMMENDED ACTIONS...
STORM SPOTTER GROUPS AND EMERGENCY MANAGEMENT PERSONNEL ACROSS THE
RISK AREA SHOULD PLAN FOR SEVERE WEATHER OPERATIONS FROM AROUND 3 PM
THROUGH THIS EVENING. SEVERE WEATHER OPERATIONS COULD CONTINUE PAST
MIDNIGHT IN PARTS OF CENTRAL AND EASTERN OKLAHOMA.

DISCUSSION...
EARLY THIS MORNING A WARM FRONT WAS LIFTING NORTH ACROSS EXTREME
NORTHERN OKLAHOMA. THE DRY LINE WAS LOCATED OVER WEST TEXAS... FROM
THE CENTRAL OKLAHOMA PANHANDLE SOUTH TO JUST EAST OF AMARILLO AND
LUBBOCK. A MODERATELY STRONG UPPER LEVEL DISTURBANCE WAS SWINGING
EAST FROM THE FOUR CORNERS AREA TOWARD THE CENTRAL PLAINS.

THE WARM FRONT WILL LIFT NORTH INTO KANSAS TODAY...ALLOWING WARM
MOIST AND UNSTABLE AIR TO OVERSPREAD THE ENTIRE AREA. AS THE UPPER
DISTURBANCE APPROACHES...THE DRY LINE WILL BEGIN MOVING EAST AND
SHOULD MOVE INTO FAR WESTERN OKLAHOMA BY NOON. IT CURRENTLY IS
EXPECTED TO REACH THE WESTERN EDGE OF THE SLIGHT RISK AREA AROUND
MID AFTERNOON. THE AIR AHEAD OF THE DRY LINE WILL DESTABILIZE
FURTHER THROUGHOUT THE DAY IN RESPONSE TO DAYTIME HEATING OF THE LOW
LEVELS. A CAP WILL BE PRESENT...WHICH WILL LIKELY DELAY THUNDERSTORM
DEVELOPMENT UNTIL MID AFTERNOON AT THE EARLIEST. BY THAT
TIME...EXTREMELY UNSTABLE CONDITIONS WILL EXIST ALONG AND AHEAD OF
THE DRY LINE...WITH CAPE VALUES LIKELY TO EXCEED 3000 OVER MUCH OF
CENTRAL AND EASTERN OKLAHOMA.

THUNDERSTORMS ARE EXPECTED TO DEVELOP INITIALLY ALONG...AND POSSIBLY
AHEAD OF...THE DRY LINE AROUND 3 OR 4 PM AS THE UPPER DISTURBANCE
ARRIVES TO PROVIDE MID-LEVEL LIFT. RAPID DEVELOPMENT...AND
STRENGTHENING TO SEVERE LEVELS...IS LIKELY DUE TO THE EXPECTED HIGH
INSTABILITY AND THE CONTINUED PRESENCE OF STRONG VERTICAL WIND SHEAR
OVER THE AREA. A FEW STORMS MAY EVOLVE INTO SUPERCELLS...WITH AN
ATTENDANT RISK OF VERY LARGE HAIL ALONG WITH A FEW TORNADOES. SEVERE
WEATHER POTENTIAL MAY CONTINUE WELL INTO THE EVENING NEAR AND EAST
OF THE DRY LINE...WHICH IS EXPECTED TO SET UP NEAR THE I-44 CORRIDOR
THIS EVENING.

IF THE DRY LINE MOVES FASTER OR SLOWER THAN CURRENTLY EXPECTED...THE
EDGE OF THE RISK AREA MAY HAVE TO BE ADJUSTED ACCORDINGLY. BUT IN
ANY CASE...THE RISK OF SEVERE WEATHER IN ANY GIVEN AREA WILL END
ONCE SURFACE WINDS TURN TO THE SOUTHWEST AND DEWPOINTS FALL OFF.

PARTS OF THE SLIGHT RISK AREA...MOST IN NORTH CENTRAL AND POSSIBLY
CENTRAL OKLAHOMA....COULD BE UPGRADED IN LATER OUTLOOKS.

PROBABILITY TABLE...
VALID THROUGH 700 AM CDT FRIDAY MAY 9.
PROBABILITY OF THUNDERSTORMS OCCURRING IN THE
NWS NORMAN COUNTY WARNING AREA...70 PERCENT.
PROBABILITY OF SEVERE STORMS IF STORMS OCCUR...90 PERCENT.

OTHER HAZARDOUS WEATHER...
ASIDE FROM THE SEVERE WEATHER DANGER...NO OTHER HAZARDOUS WEATHER IS
EXPECTED THROUGH TONIGHT.

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

THUNDERSTORM OUTLOOK...
THE GREATEST SEVERE WEATHER POTENTIAL MAY SHIFT NORTH OF THE AREA ON
FRIDAY...BUT THERE WILL BE SOME CHANCE OF SEVERE WEATHER AGAIN AT
LEAST ACROSS NORTHERN OKLAHOMA. A RISK OF SEVERE WEATHER WILL
CONTINUE IN EASTERN PARTS OF THE AREA ON SATURDAY. THUNDERSTORM
CHANCES WILL RETURN TO THE AREA MONDAY THROUGH WEDNESDAY.

OTHER HAZARDOUS WEATHER...
NONE IS EXPECTED.

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

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NORMAN OK
1035 AM CDT THU MAY 8 2003

IN GENERAL... THINGS ARE GOING AS PLANNED. WE MAY NEED TO MAKE SOME
ADJUSTMENTS TO WIND SPEEDS FOR THIS AFTERNOON IF MODEL FORECASTS
TURN OUT TO BE CORRECT. THIS IS MAINLY A CONCERN IN NORTHWEST
OKLAHOMA... WHERE SPEEDS MAY TURN OUT TO BE STRONGER THAN CURRENTLY
FORECAST. SO FAR... PROFILERS SUGGEST THAT SPEEDS WILL NOT GET
QUITE THAT STRONG. SIMILARLY... IN THAT SAME AREA TEMPERATURES ARE
RUNNING A LITTLE WARMER THAN THE GOING FORECAST. HOWEVER...
SOMEWHAT COOLER AIR UPSTREAM SHOULD BRING THE ACTUAL READINGS AND
THE FORECAST BACK TOGETHER WITHIN AN HOUR OR TWO.

WILL WATCH TRENDS AND MAKE ADJUSTMENTS AS NEEDED.

1135 AM CDT THU MAY 8 2003

.NOW...
AT 1130 AM... A DRYLINE ACROSS NORTHWEST OKLAHOMA INTO THE SOUTHERN
TEXAS PANHANDLE EXTENDED FROM NEAR FREEDOM... TO CHEYENNE... TO JUST
WEST OF CHILDRESS. TO THE EAST OF THE DRYLINE... VERY UNSTABLE AIR
WAS LOCATED ACROSS MUCH OF WESTERN AND CENTRAL OKLAHOMA... AND THE
WESTERN PART OF NORTH TEXAS. ALTHOUGH LOW CLOUDS PERSISTED ACROSS
CENTRAL OKLAHOMA... SKIES WERE CLEARING OVER WESTERN OKLAHOMA AND
NORTH TEXAS... ALLOWING TEMPERATURES TO WARM INTO THE MIDDLE 80S.

BY MID AFTERNOON... THE DRYLINE IS EXPECTED TO MOVE TO NEAR A
CHEROKEE... TO FREDERICK... TO JUST WEST OF WICHITA FALLS LINE.
ALTHOUGH WARM TEMPERATURES ALOFT WILL TEND TO SUPPRESS THUNDERSTORM
DEVELOPMENT THROUGH EARLY AFTERNOON... INCREASING CONVERGENCE ALONG
THE DRYLINE AND ADDITIONAL HEATING SHOULD ERODE THE CAPPING
INVERSION SUFFICIENTLY FOR THUNDERSTORMS TO DEVELOP. THUS SCATTERED
THUNDERSTORMS ARE EXPECTED TO FORM ALONG AND A LITTLE AHEAD OF THE
DRYLINE... MAINLY FROM MID AFTERNOON INTO THE EVENING HOURS.

DUE TO THE HIGH INSTABILITY ACROSS THE AREA... ONCE STORMS FORM...
THEY WILL QUICKLY BECOME SEVERE.

MEANWHILE... STRONG NORTHWEST WINDS ARE EXPECTED TO DEVELOP BEHIND
THE DRYLINE IN NORTHWEST OKLAHOMA LATER THIS AFTERNOON.

219 PM CDT THUS MAY 8 2003

...POTENTIAL FOR A SIGNIFICANT SEVERE WEATHER OUTBREAK INCLUDING
SUPERCELLS AND TORNADOES ACROSS THE CENTRAL THIRD OF OKLAHOMA DURING
THE NEXT 3-9 HOURS...

MID/UPPER LEVEL TROF AND SFC LOW CONT TO RAPIDLY DEEPEN OVER WRN
KS/ERN CO EARLY THIS AFTERNOON.. AND THERE IS SUBTLE EVIDENCE OF A
SECONDARY IMPULSE PUSHING EWD ACROSS NEW MEXICO. 18Z OUN SOUNDING
INDICATES THAT CAPPING IS MUCH WEAKER THAN PREVIOUSLY EXPECTED ALONG
DRYLINE ACROSS MOST OF OKLAHOMA. POTENT THERMODYNAMIC PROFILE IS
EVIDENT WITH VERY HIGH BOUNDARY LAYER MOISTURE CONTENT.. LOW LCL
HGHTS AND STEEP MID LEVEL LAPSE RATES. IN ADDITION..THE HODOGRAPH
SHOWS SIGNIFICANT LOW LEVEL AND DEEP LAYER SHEAR IN PLACE.. HILITED
BY A DISTINCT KINK IN THE HODOGRAPH AT ABOUT 1.5 KM AGL. THIS TYPE
OF LOW LEVEL SHEAR PROFILE IN COMBINATION WITH ABOVE MENTIONED
THERMODYNAMICS HAS OFTEN BEEN ASSOCIATED WITH ENVIRONMENTS
SUPPORTIVE OF LONG LIVED STRONG/VIOLENT TORNADOES. EXPECT
INITIATION INVOF THE DRYLINE WITHIN THE NEXT COUPLE HOURS WITH
SUPERCELL DEVELOPMENT LIKELY. SVR THREAT WILL LIKELY CONTINUE WELL
INTO THE NITE AS STRONG UVVS CONT ALONG DRYLINE UNTIL AT LEAST 06Z
ACROSS MUCH OF OKLAHOMA. LIKELY TO SEE DEVELOPMENT SWD INTO TEXAS
LATER THIS AFT/EVE.

INSTABILITY AXIS WILL RELOAD FRIDAY OVER THE SE ZONES.. AND THEN
EXPAND NWWD INTO REDEVELOPING WARM FRONTAL ZONE FRIDAY NITE. HAVE
READJUSTED POPS TO ACCOUNT FOR THIS THINKING. NEXT WAVE WILL EJECT
ONTO THE PLAINS SATURDAY.. BUT MAIN FOCUS FOR ACTIVITY WITH THIS
WAVE LOOKS TO BE NORTHEAST OF THE OUN CWA ATTM. HOWEVER..STILL
LIKELY TO SEE AT LEAST A FEW STORMS ALONG/SE OF I44 CORRIDOR AHEAD
OF DRYLINE/FRONT. IT APPEARS THAT LOW LEVEL RIDGING WILL FINALLY
BUILD SWD FAR ENUF SUNDAY INTO MONDAY TO ALLOW FOR A BRIEF RESPITE
FROM STORMS..BUT TROPICAL BOUNDARY LAYER AIR WILL BE LURKING CLOSE
BY AND SHUD MOVE BACK NWD MONDAY/TUES AS LONG WAVE TROF RELOADS OVER
THE WRN CONUS. WE WILL BRING SLGT CHC POPS BACK INTO THE SW ZONES
MONDAY AFTERNOON WITH ONSET OF MOISTURE RETURN.. AND THEN
EXPAND/INCREASE POPS ACROSS THE REST OF THE AREA THRU MID WEEK.
MORE BOUTS OF SVR STORMS SEEM LIKELY AS SIGNIFICANT INSTABILITY AXIS
REMAINS SUPERIMPOSED UNDERNEATH STRONG MID LEVEL FLOW.
