Area forecast discussion, May 10, 7:14 PM CST, 11 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE FORT WORTH TX 814 PM CDT MON MAY 10 2010 .UPDATE... WIND SPEEDS WILL SLOWLY DECREASE THROUGH THE EVENING AS THE BOUNDARY LAYER DECOUPLES. THEREFORE...WILL LET THE WIND ADVISORY EXPIRE AT 8 PM. FWD SOUNDING SHOWS THAT THE CAP IS HOLDING STRONG BUT THAT IT IS VERY UNSTABLE ABOVE THE CAP. IT ALSO APPEARS THAT THE DRY LINE IS STALLING AS EXPECTED. WILL CONTINUE TO SEE A CHANCE FOR ELEVATED STRONG TO SEVERE STORMS WITH HAIL BEING THE PRIMARY THREAT. WILL UPDATE TO REMOVE THE WIND ADVISORY AND ADJUST THE WIND SPEEDS. && .AVIATION... WEAK THUNDERSTORMS NEAR POSSUM KINGDOM MOVING DUE EAST TOWARDS METROPLEX TAF SITES. CAP REMAINS IN PLACE ACROSS THE METROPLEX...AS SEEN IN FWD AND AIRCRAFT SOUNDINGS. HAVE TIMED STORMS INTO AREA AFTER 02Z (9 PM) AND HAVE AMENDED THE METROPLEX TAFS TO SHOW VCTS...AS WEAKENING STORMS MOVE INTO THE VICINITY. 84 && .PREV DISCUSSION... /ISSUED 341 PM CDT MON MAY 10 2010/ SURFACE DRYLINE CURRENTLY EXTENDS FROM EXTREME WESTERN OKLAHOMA TO NEAR VERNON TO NEAR BIG SPRING. CONVECTION HAS INITIATED IN NORTHERN OKLAHOMA WHERE THE CAP HAS BEEN MUCH WEAKER. SCATTERED CU HAVE DEVELOPED WEST OF THE CWA AND IS INDICATIVE OF FORCING AND THE UVVS WILL CONTINUE TO TRY TO BREAK THE CAP AS THE DRYLINE PROGRESSES EASTWARD. THE 18Z SPECIAL KFWD RAOB ACTUALLY INDICATED A STRONGER EML THAN THE 12Z SOUNDING AND CURRENT SOUNDINGS FROM AIRCRAFT DATA INDICATE THE CAP IS CONTINUING TO STRENGTHEN. GIVEN THE STRENGTH OF THE CAP...THINK MOST AREAS OF NORTH TEXAS SHOULD BE HARD PRESSED TO SEE ANY CONVECTION THIS EVENING. A FEW RUNS OF THE RUC AND OTHER HIGH RESOLUTION MODELS HAVE BROKEN THE CAP AND INDICATE ISOLATED CONVECTION. HOWEVER...THE MODELS HAVE BEEN TOO BULLISH ON THE MOISTURE RETURN SOUTH OF THE WARM FRONT AND HAVE BEEN WEAKENING THE CAP AS THE AFTERNOON PROGRESSES. OBVIOUSLY IF THE CU TO OUR WEST INITIATES INTO CONVECTION...THE ATMOSPHERE WILL BE MORE THAN ABLE TO SUPPORT SEVERE STORMS. SBCAPE VALUES ARE GREATER THAN 3000 J/KG WITH 0-6KM SHEAR GREATER THAN 50 KNOTS. STORMS THAT DEVELOP THEREFORE SHOULD QUICKLY BECOME SEVERE WITH LARGE HAIL AND DAMAGING WINDS THE MAIN THREATS...BUT CANT RULE OUT ISOLATED TORNADOES. THE MOST LIKELY AREAS TO SEE CONVECTION WILL BE IN THE NORTHWESTERN ZONES OR RED RIVER COUNTIES AND WOULD LIKELY BE CLIPPED BY STORMS MOVING TO THE NORTHEAST/EAST. WILL CARRY 20 POPS WITH SEVERE MENTIONED IN THE ZONES FOR AREAS NORTH OF AN EASTLAND TO SHERMAN LINE. WILL ALSO CARRY A 10 POP WITH WEATHER MENTIONED IN THE ZONES NORTH OF A GOLDTHWAITE TO DALLAS TO PARIS LINE LATE THIS EVENING WITH ALL POPS TRANSITIONING EAST OVERNIGHT. THE DRYLINE WILL RETREAT SLIGHTLY OVERNIGHT AND THEN WILL MOVE EAST AND APPROACH THE WESTERN ZONES OF NORTH TEXAS TOMORROW AFTERNOON. THERE WILL BE LITTLE IN THE WAY OF FORCING TOMORROW AFTERNOON AND WILL ONLY MENTION 10 POPS WITH ISOLATED THUNDER IN THE AFTERNOON AND EVENING. ONCE AGAIN...IF THUNDERSTORMS DO DEVELOP THEY WILL LIKELY BECOME SEVERE. RAIN CHANCES WILL END FOR A COUPLE OF DAYS BEFORE RETURNING AGAIN THURSDAY THROUGH SATURDAY. A COLD FRONT WILL APPROACH THE AREA THURSDAY AND THE BOUNDARY WILL THEN LINGER ACROSS THE AREA FOR A COUPLE OF DAYS. THIS WILL PROVIDE A FOCUS FOR SHOWERS AND THUNDERSTORMS AND WILL CONTINUE WITH THE CHANCE POPS ACROSS THE CWA. 85/NH && .PRELIMINARY POINT TEMPS/POPS... DALLAS-FT.
