AREA FORECAST DISCUSSION...UPDATED NATIONAL WEATHER SERVICE FORT WORTH TX 1100 PM CDT THU APR 30 2009 .AVIATION... SEE UPDATE BELOW FOR AREA THUNDERSTORM PROGNOSIS. WILL NOT PUT TSTMS IN TAFS...BUT SITUATION NEEDS TO BE WATCHED CLOSELY TO SEE HOW FAR SOUTH THE STORMS WILL MOVE. OTHERWISE...PREVIOUS TAF PHILOSOPHY ON TRACK...STRATUS EXPECTED OVERNIGHT. 84 && .UPDATE... 953 PM OVERNIGHT FORECAST IS LARGELY ON TRACK...BUT WILL NEED TO BUMP LOWS UP A COUPLE DEGREES GIVEN THE CURRENT DEWPOINTS NEAR 70 DEGREES AT MOST LOCATIONS. THESE DEWPOINTS NEAR 70 DEGREES...COMBINED WITH HEATING TOMORROW WILL CREATE A VERY UNSTABLE ENVIRONMENT OVER NORTH TEXAS TOMORROW AFTERNOON. CAPES ALONG AND NORTH OF I-20 WILL APPROACH 4000 J/KG WITH WEAKENING CIN. AS COLD FRONT IN OKLAHOMA SAGS SOUTH...IT WILL LIKELY INITIATE STRONG/SEVERE STORMS IN SOUTHERN OKLAHOMA BY LATE AFTERNOON. EXPECT A CLUSTER OF THESE STORMS TO DEVELOP AND TRACK SOUTHEAST INTO THE RED RIVER VALLEY AND PERHAPS AS FAR SOUTH AS THE I-20 CORRIDOR DURING THE EVENING HOURS. THE 18Z NAM AND NOW THE NEW 0Z NAM IS MODELING THIS SCENARIO. THIS FITS WITH CLIMATOLOGY OF THE PATTERN WE ARE IN...AND IT SHOWS SIMILARITIES TO THE JUNE 1 2004 EVENT...JUST DISPLACED 100 MILES FARTHER NW. HAVE INCREASED POPS ALONG AND NORTH OF I-20 FOR FRIDAY EVENING AND ADDED A MENTION OF SEVERE/HEAVY RAINFALL. TR.92 && .PREV AVIATION... 611 PM VFR THROUGH MIDNIGHT...THEN STRATUS FLOWS BACK NORTH BRINGING MVFR CIGS WITH SOME IFR MIXED IN NEAR SUNRISE. SOME MVFR FOG/MIST ALSO EXPECTED BY MORNING. CIGS/VISBYS SHOULD BE BACK TO VFR BY LATE MORNING...AND SKIDS SHOULD CLEAR OUT LATE FRIDAY AFTERNOON. 84 && .PREV UPDATE... .UPDATE... SUBSIDENCE BEHIND LAST NIGHTS SHORTWAVE REMAINS IN CONTROL...AND THUS CAP WILL HOLD OVER NORTH TEXAS. THIS IS CONFIRMED BY LATEST ACARS TEMP PROFILE DATA. REMOVING LOW POPS...AND MAKING OTHER MINOR ADJUSTMENTS TO SKY/TEMP/DEWPOINT GRIDS. TR.92 && .PREV DISCUSSION... /ISSUED 342 PM CDT THU APR 30 2009/ SOME LIGHT REFLECTIVITIES ARE BEGINNING TO SHOW ON AREA RADARS ACROSS THE EASTERN HALF OF THE STATE. THUNDERSTORMS HAVE YET TO DEVELOP IN TEXAS AND THE CHANCE FOR SEVERE STORMS IN NORTH TEXAS APPEARS TO BE DECREASING. INSTABILITY STILL REMAINS HIGH BUT THE CAP IS STRONG. TEMPERATURES THIS PAST HOUR ARE STILL JUST BELOW CONVECTIVE TEMPERATURES /EXCEPT OUR WEST WHERE TEMPERATURES HAVE SOARED INTO THE UPPER 80S/ AND WILL NEED TO CONTINUE TO MONITOR THE RADAR IN CASE A STORM CAN BREAK THROUGH THE CAP. CANNOT IDENTIFY ANY OUTFLOW BOUNDARIES IN NORTH TEXAS AT THIS TIME AND LIFTING IS WEAK ACROSS THE AREA. THINK THAT A FEW STORMS MAY STILL FIRE ALONG THE DRYLINE IN THE NEXT FEW HOURS. HOWEVER...THESE STORMS WILL LIKELY BE SLOW MOVING AND MAY DIMINISH JUST AFTER SUNSET BEFORE REACHING NORTH TEXAS. WILL HOLD ONTO 20 POPS THROUGH MIDNIGHT ACROSS THE CWA. FRIDAY WILL BE DRY AND THEN THE NEXT RAIN EPISODE BEGINS FRIDAY NIGHT IN THE NORTHERN PORTIONS OF NORTH TEXAS. A COLD FRONT THAT IS CURRENTLY DRAPED ACROSS CENTRAL KANSAS AND INTO THE NORTHERN TEXAS PANHANDLE WILL SLOWLY SLIDE SOUTH FRIDAY AND STALL OVER OKLAHOMA. IT WILL SLOWLY ADVANCE SOUTH ON SATURDAY TO THE RED RIVER...FINALLY GETTING A PUSH SATURDAY NIGHT AND SUNDAY FROM AN APPROACHING UPPER LEVEL DISTURBANCE. THE FRONT IS EXPECTED TO MOVE THROUGH ALL OF NORTH TEXAS BY SUNDAY EVENING. DUE TO THE SLOW NATURE OF THE FRONT...FLOODING WILL AGAIN BE A LIKELY THREAT...ESPECIALLY ACROSS THE NORTHERN HALF OF NORTH TEXAS. WILL HOLD OFF ON ISSUING A FLOOD WATCH AT THIS TIME BUT ONE WILL LIKELY BE NEEDED BY FRIDAY NIGHT. SEVERE WEATHER /MAYBE A FEW ROUNDS OF IT/ WILL BE POSSIBLE THIS WEEKEND ALONG AND AHEAD OF THE FRONT. THE RAIN WILL COME TO AN END ON MONDAY AND WILL KEEP SLIGHT RAIN CHANCES TUESDAY NIGHT AND WEDNESDAY AS ANOTHER UPPER LEVEL DISTURBANCE MOVES THROUGH THE CENTRAL PLAINS. TEMPERATURES WILL COOL BEHIND THE FRONT BUT WILL WARM BACK UP NEXT WEEK. 82/JLD && .PRELIMINARY POINT TEMPS/POPS... DALLAS-FT.
