AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE NORMAN OK 227 PM CDT TUE APR 6 2004 .DISCUSSION... MAIN UPPER LEVEL LOW CENTER STILL MEANDERING SLOWLY TO THE EAST EARLY THIS AFTERNOON..NOW CROSSING THE NM/TX BORDER TO THE WEST OF LBB. A RATHER STRONG LOBE CONTINUES TO ROTATE NWD FROM THE NRN TX PANHANDLE AND NRN OK ALONG THE NE PERIPHERY OF THE MAIN CIRCULATION CENTER. BAND OF RAIN ACROSS NRN OK SHUD CONT TO ROTATE NWWD AND SLOWLY DISSIPATE BY THIS EVENING. MEANWHILE..INITIAL DEVELOPMENT OF SMALL DEEP CONVECTIVE ELEMENTS HAS BEEN NOTED ACROSS MUCH OF WEST TX DURING THE PAST HOUR WHERE DAYTIME HEATING OF LINGERING LOW LEVEL MOIST AXIS HAS OCCURRED UNDERNEATH COLD CORE ALOFT. AS UPPER LOW MOVES SLOWLY EASTWARD THROUGH WEDNESDAY..EXPECT CONVECTION TO CONTINUE TO EXPAND INTO THIS EVENING ACROSS SW OK/NTEX WHERE BEST LOW LEVEL MASS CONVERGENCE WILL REMAIN. INSTABILITY WILL BE A LIMITING FACTOR..BUT DEEP LAYER SHEAR WILL BE SUFFICIENT FOR AT LEAST MARGINALLY ORGANIZED STORMS. SVR THREAT LIKELY LIMITED TO HAIL AND MAYBE SOME WIND..BUT SHUD END BY SHORTLY AFTER SUNSET. EXPECT ANOTHER LOBE OF PRECIP TO EVOLVE FROM THIS ACTIVITY AND MIGRATE NEWD ACROSS MUCH OF THE OUN CWA OVERNITE. UPPER LOW WILL DEAMPLIFY AND MOVE EAST OF THE CWA BY LATE TOMORROW..WITH ONLY SMALL PRECIP CHANCES LINGERING BY LATE WED. BRIEF PERIOD OF LOW LEVEL RIDGING WILL HELP TO STRENGTHEN LOW LEVEL BAROCLINIC ZONE JUST TO OUR SOUTHWEST THUR INTO THUR NITE..WHILE NEXT UPPER SYSTEM ENCROACHES ON THE SRN PLAINS FROM THE SRN ROCKIES THUR NITE. LATEST MODEL DATA IS CONSISTENT IN DEVELOPING A VERY NICE NOCTURNAL MCS SIGNAL MOVING FROM WEST TO EAST ACROSS OK LATE THURS NITE INTO FRIDAY. UNLIKE MANY SEEMINGLY SPURIOUS MODEL QPF SIGNALS.. A MODERATE TO STRONG LOW LEVEL WAA PATTERN IS EVIDENT..ALONG WITH A 40 KT LLJ BY 12Z FRI MORNING. WITH THIS IN MIND THERE IS AT LEAST ENUF DATA TO SUPPORT INTRODUCTION OF CHC POPS FOR THIS TIME PERIOD. TIMING OF STRONGER COLD FRONT STILL A BIT IN QUESTION..BUT WILL NOT DEVIATE TOO MUCH FROM GOING FORECAST WHICH BRINGS FRONT INTO NW OK FRI AFTERNOON AND THRU THE REST OF THE CWA BY SAT MORNING. DEEP LAYER SHEAR WILL BE INCREASING..AND EXPECT SOME SVR THREAT FRI NITE ROUGHLY ALONG/SE OF I44 CORRIDOR. COLDER AIRMASS TO SETTLE SWD INTO THE SRN PLAINS OVER THE WEEKEND.. WITH NEAR FREEZING TEMPS POSSIBLE PARTS OF NRN/NW OK. HOWEVER..THIS IS WELL WITHIN THE CLIMATOLOGICAL LAST FREEZE PERIOD FOR THIS PART OF OUR CWA. WARMING TREND SHUD COMMENCE OUT WEST LATE MON AND ACROSS THE REST OF OK/NTEX TUE/WED. && .PRELIMINARY POINT TEMPS/POPS...

NATIONAL WEATHER SERVICE NORMAN OK
1200 PM CDT TUE APR 6 2004
OKZ004>048-050>052-TXZ083>090-071200-
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 THROUGH MID EVENING
ACROSS WESTERN NORTH TEXAS AND PORTIONS OF SOUTHERN OKLAHOMA.
LOCATION...
THE SLIGHT RISK AREA IS SOUTH OF A LINE FROM HOLLIS TO DURANT...
INCLUDING ALL OF WESTERN NORTH TEXAS.
TIMING...
THE MOST LIKELY TIME FOR SEVERE THUNDERSTORMS WILL BE FROM MID
AFTERNOON THROUGH THIS EVENING.
IMPACTS...
LARGE HAIL WILL BE THE PRIMARY SEVERE WEATHER THREAT AND MAY CAUSE
DAMAGE TO AUTOMOBILES AND TENDER VEGETATION.
RECOMMENDED ACTIONS...
STORM SPOTTER GROUPS AND EMERGENCY MANAGEMENT PERSONNEL ACROSS THE
RISK AREA SHOULD BE PREPARED FOR SEVERE WEATHER OPERATIONS FROM MID
AFTERNOON INTO THIS EVENING.
DISCUSSION...
AN UPPER LEVEL LOW PRESSURE SYSTEM LOCATED OVER WEST TEXAS AT MIDDAY
WILL MOVE SLOWLY NORTHEAST THROUGH THE NIGHT. AS IT DOES SO...
TEMPERATURES ALOFT WILL GRADUALLY COOL. MEANWHILE... HEATING OVER
PORTIONS OF WESTERN NORTH TEXAS AND SOUTHERN OKLAHOMA THIS
AFTERNOON... COMBINED WITH THE COOLING ALOFT... WILL RESULT IN THE
AIRMASS ACROSS THE AREA BECOMING MORE UNSTABLE.
SCATTERED THUNDERSTORMS ARE EXPECTED TO DEVELOP DURING THE MID TO
LATE AFTERNOON HOURS OVER WESTERN NORTH TEXAS AND SOUTHERN OKLAHOMA.
A FEW OF THE STORMS COULD BECOME SEVERE... PRODUCING LARGE HAIL UP
TO THE SIZE OF HALF DOLLARS. A LIMITING FACTOR FOR THE DEVELOPMENT
OF MORE WIDESPREAD OR STRONGLY SEVERE THUNDERSTORMS WILL BE THE
PRESENCE OF MARGINAL LOW LEVEL MOISTURE RESULTING IN REDUCED
INSTABILITIES. THE RISK FOR SEVERE THUNDERSTORMS WILL DIMINISH BY
LATE EVENING AS SURFACE TEMPERATURES COOL AND INSTABILITIES DECREASE.
