An approaching upper level system helped a large area of showers and thunderstorms to develop and move southeast across north Texas. The slow moving area of rain produced mainly nuisance flooding problems, but water did cover one roadway in Young County where several inches of rain fell.

NWS Fort Worth, TX wrote its last area forecast discussion before the first event at Sep 25, 5:56 AM CST, 2 hours 6 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE FORT WORTH TX 656 AM CDT SAT SEP 25 2010 .AVIATION... CHALLENGING FORECAST THIS MORNING WITH ONGOING CONVECTION COMPLICATING THE SHORT TERM CEILING AND WEATHER TRENDS. CLUSTER OF CONVECTION NEAR AND JUST SOUTHEAST OF DALLAS LOVE FIELD /KDAL/ WAS ONLY MOVING VERY SLOWLY TO THE EAST. ANOTHER MORE SUBSTANTIAL MCS WAS LOCATED TO THE WEST ACROSS PARKER AND WISE COUNTIES AND WAS MOVING SLOWLY EAST. EVEN THOUGH A DIMINISHING TREND IS FORECAST LATER THIS MORNING AND EARLY THIS AFTERNOON...THE CURRENT COVERAGE ARGUES FOR A CONTINUED MENTION OF CB AND SHRA GROUP WITH MVFR CIGS AND VSBYS IN THE METRO TAFS UNTIL 2200 UTC (500 PM CDT). AT KACT...EXPECT ISOLATED SHOWER/THUNDERSTORM ACTIVITY TO DEVELOP THIS AFTERNOON WITH AID OF DAYTIME HEATING AND NEARBY SURFACE BOUNDARY. CONDITIONS WILL IMPROVE AT ALL SITES THIS EVENING AS ATMOSPHERE DRIES OUT AND STRONGER SURFACE FRONT PUSHES IN FROM THE NORTH. 09 && .PREV DISCUSSION... /ISSUED 439 AM CDT SAT SEP 25 2010/ 00Z UPPER AIR ANALYSIS INDICATES A STRONG SHORTWAVE TROUGH OVER THE GREAT LAKES REGION...AND A SECONDARY STRONG TROUGH DIGGING SOUTH THRU THE NORTHERN PLAINS. IN THE MID LEVELS A WEAK DEFORMATION ZONE WAS LOCATED ROUGHLY FROM EASTERN OK SOUTHWEST INTO FAR WEST TX. H250 ANALYSIS INDICATED THE PRESENCE OF A JET STREAK OVER NORTHERN NEW MEXICO WHICH WAS ASSOCIATED WITH AN UPPER LVL SHEAR AXIS. FOR TODAY...WITHIN THE MID LVL DEFORMATION ZONE AND JUST EAST OF THE UPPER LVL SHEAR AXIS THE NAM INDICATES PWAT VALUES HAVE CLIMBED INTO THE 2 TO 2.25 INCH RANGE EARLY THIS MORNING. IN NORTH TX THIS COVERS AREAS ALONG AND JUST NORTH OF THE INTERSTATE 20 CORRIDOR. WITHIN THE DEFORMATION ZONE EXPECT THAT SOME WEAK FRONTOGENETIC FORCING COMBINED WITH THE WEAK LARGE SCALE FORCING FOR ASCENT ASSOCIATED WITH THE APPROACHING UPPER LVL SHEAR AXIS IS RESPONSIBLE FOR THE LINE OF HEAVY RAIN SHOWERS AND TSTMS CURRENTLY IN PLACE OVER WEST CENTRAL AND NORTH TX. 09Z REGIONAL RADAR DATA INDICATED THAT CELLS WITHIN THIS LINE WERE VERY SLOW MOVING AND EXHIBITED LOW ECHO CENTROID CORES. THESE FACTORS COMBINE TO INDICATE THE PRESENCE OF SOME WARM RAIN PROCESSES...VERY EFFICIENT RAINFALL PRODUCTION AND FLASH FLOODING POTENTIAL. EXPECT THE PRIMARY HEAVY RAIN/FLOODING POTENTIAL IS GOING TO BE PRIMARILY RELEGATED TO THE MORNING HRS AS THE UPPER LVL SHEAR AXIS PUSHES SOUTHEAST TOWARDS NORTH TX. BY THIS AFTERNOON THE UPPER SHEAR AXIS IS PROGGED TO BE JUST SOUTH OF THE RED RIVER WHICH SHOULD BRING SOME FORCING FOR SUBSIDENCE INTO THE AREA. IN THE FORECAST TRACKED THIS UPPER SHEAR AXIS IN TERMS OF POPS FOR TODAY. HAVE LIKELY POPS IN THE MORNING ALONG THE INTERSTATE 20 CORRIDOR...AND THEN FOCUS POPS OVER THE SOUTHERN HALF OF THE CWA FOR THIS AFTERNOON. WITH CLOUDY SKIES AND WIDESPREAD HEAVY RAINFALL...EXPECT TEMPERATURES WILL ONLY CLIMB 10 TO 15 DEGREES TODAY...KEEPING HIGHS IN THE MID 80S FOR MOST LOCATIONS. TONIGHT...THE UPPER SHEAR AXIS IS EXPECTED TO CLEAR THE CWA AFTER MIDNIGHT. AFTER THE AXIS OF POSITIVE POTENTIAL VORTICITY ADVECTION MOVES SOUTH OF THE CWA THINK THAT FORCING FOR SUBSIDENCE WILL PREVENT ADDITIONAL RAIN SHOWER ACTIVITY FROM DEVELOPING. SHOULD SEE SKIES CLEAR LATE TONIGHT FROM NORTH TO SOUTH AS FORCING FOR SUBSIDENCE MOVES INTO THE AREA. SUNDAY...THE SECONDARY STRONG SHORTWAVE TROUGH WILL USHER IN A FAIRLY STRONG COLD FRONT SUNDAY MORNING. DUE TO THE SUBSIDENCE OVER THE CWA BEHIND THE PASSAGE OF THE SHEAR AXIS OVERNIGHT...THINK THAT MID LVLS WILL BE TOO DRY FOR ANY RAIN SHOWER ACTIVITY TO DEVELOP ALONG THE COLD FRONT. STRONG COLD AIR ADVECTION BEHIND THE FRONT WILL KEEP TEMPERATURES IN THE UPPER 70S FOR HIGHS FOR MANY LOCATIONS. BEHIND THE FRONT NORTHERLY WINDS LOOK TO PICK UP TO 15 TO 20 MPH WITH GUSTS TO 30 MPH. THIS FRONT WILL ALSO BRING IN A VERY DRY LOW LEVEL AIRMASS WITH DEW POINTS FALLING INTO THE LOWER 50S. SUNDAY NIGHT THRU FRIDAY...IN GENERAL THE PERIOD LOOKS TO REMAIN DRY WITH MODELS KEEPING LOW LEVEL NORTHERLY FLOW IN PLACE OVER THE SOUTHERN PLAINS THRU THE PERIOD. TEMPERATURES WILL SLOWLY CLIMB THROUGHOUT THE WEEK AS PERSISTENT CLEAR SKIES WILL ALLOW FOR PLENTIFUL SUNSHINE THRU THE PERIOD. CAVANAUGH && .PRELIMINARY POINT TEMPS/POPS... DALLAS-FT.
