NWS Fort Worth, TX wrote its last area forecast discussion before the first event at Sep 17, 1:52 PM CST, 1 hour 33 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE FORT WORTH TX 252 PM CDT FRI SEP 17 2010 .DISCUSSION... 12Z UPPER AIR ANALYSIS DEPICTED BROAD UPPER LVL RIDGING OVER THE SOUTHERN CONUS. WHILE THE AIRMASS OVER DFW WAS RELATIVELY DRY THIS MORNING THERE WAS EVIDENCE AT THE MID LVLS OF MOISTURE MOVING INTO THE SOUTHERN CWA DUE TO SOUTHEASTERLY FLOW ALOFT. 18Z WATER VAPOR IMAGERY INDICATED A WEAK SHORTWAVE TROUGH MOVING EAST OUT OF WEST TX. OUT AHEAD OF THIS TROUGH WEAK LARGE SCALE FORCING FOR ASCENT COMBINED WITH BETTER TROPOSPHERIC MOISTURE HAS ALLOWED FOR SOME ISOLATED RAIN SHOWER AND THUNDERSTORM ACTIVITY TO DEVELOP ACROSS THE SOUTHERN CWA THIS AFTERNOON. WITH DEEP LAYER SHEAR VALUES REMAINING VERY WEAK AND ONLY MARGINAL INSTABILITY PRESENT...DO NOT THINK TSTM ACTIVITY WILL HAVE MUCH OF A CHANCE TO BECOME ORGANIZED OR SEVERE THIS AFTERNOON. BRIEF HEAVY RAINFALL AND GUSTY WINDS ARE THE MOST LIKELY TSTM HAZARDS. EXPECT TSTM ACTIVITY TO DIMINISH QUICKLY AFTER SUNSET AS THE WEAK FORCING FOR ASCENT AND THE LACK OF ENVIRONMENTAL SHEAR BOTH POINT TO TSTM ACTIVITY BEING DIURNALLY DRIVEN. THIS WEEKEND...UPPER LVL RIDGING LOOKS TO REMAIN CENTERED OVER THE SOUTHERN PLAINS THIS WEEKEND. THIS WILL KEEP THE LATE SUMMER HEAT IN PLACE OVER NORTH TX AS WELL AS KEEPING THE FORECAST DRY FOR MUCH OF THE REGION. AT THIS TIME DO NOT HAVE ANY POPS IN THE FORECAST FOR THIS WEEKEND ACRS THE ENTIRE CWA. IF ANY ISOLATED SHOWER OR STORM WERE TO DEVELOP IT WOULD LIKELY BE SOUTH OF WACO WHERE DEEPER GULF MOISTURE IS EXPECTED TO RESIDE. HIGHS WILL REMAIN IN THE MID 90S FOR MOST LOCATIONS WITH LIGHT SOUTHEASTERLY WINDS. MONDAY THRU FRIDAY...THE UPPER LVL RIDGE OVER THE SOUTHERN PLAINS BEGINS TO BREAK DOWN ON MONDAY AS A STRONG SHORTWAVE TROUGH PUSHES THRU THE NORTHERN PLAINS. THIS WILL NOT RESULT IN A FRONTAL PASSAGE THRU THE SOUTHERN PLAINS...BUT WITH THE RIDGE MOVING OFF TO THE EAST...CAN EXPECT SOME DAILY PEAK HEATING ISOLATED TSTM ACTIVITY TO DEVELOP. FOR TUESDAY AND WEDNESDAY THE BEST CHANCE FOR SOME ISOLATED TSTMS WILL LIKELY HOLD SOUTH OF INTERSTATE 20 IN THE DEEPER GULF MOISTURE. BY THURSDAY PERSISTENT SOUTHERLY FLOW IS EXPECTED TO BRING DEEPER GULF MOISTURE THRU ALL OF NORTH TX AND THEREFORE EXPANDED THE SLIGHT CHANCE POPS TO COVER THE ENTIRE FORECAST AREA. THRU THE ENTIRE FORECAST PERIOD H500 FLOW LOOKS TO REMAIN AT OR BELOW 15 KTS...SO ANTICIPATE TSTM ACTIVITY WILL BE LARGELY UNORGANIZED WITH ONLY LOW END/PULSE TYPE SEVERE CHANCES. EXPECT TEMPERATURES TO REMAIN ABOVE NORMAL WITH HIGHS CONTINUING TO TOP OUT ABOVE 90 DEGREES FOR MOST LOCATIONS THRU THE UPCOMING WEEK. NEXT WEEKEND...THE ECMWF INDICATED THE PASSAGE OF A COLD FRONT THRU THE SOUTHERN PLAINS SATURDAY NIGHT INTO SUNDAY. IF THIS PANS OUT SHOULD SEE AT LEAST A BRIEF RETURN TO NORMAL TEMPERATURES AND BETTER TSTM CHANCES. IF THE FRONT HOLDS OFF TO THE NORTH...THE ABOVE NORMAL TEMPERATURES WILL CONTINUE.
