NWS San Angelo, TX wrote its last area forecast discussion before the first event at Sep 24, 10:49 PM CST, 4 hours 1 minute earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE SAN ANGELO TX 1149 PM CDT FRI SEP 24 2010 .DISCUSSION... SEE 06Z AVIATION DISCUSSION BELOW. && .AVIATION... LIGHT TO MODERATE SHOWERS CONTINUE ACROSS THE BIG COUNTRY AND NORTHERN CONCHO VALLEY THIS EVENING BUT WILL CONTINUE TO WEAKEN WITH TIME. HOWEVER...SHOWERY ACTIVITY WILL BE AROUND ALL NIGHT. THE COLD FRONT TO THE NORTH WILL SHARPEN AS HIGH PRESSURE BUILDS INTO THE SOUTHERN PLAINS EARLY SATURDAY. THIS WILL PROVIDE A WIND SHIFT TO THE NORTHEAST DURING THE DAY. SHOWERS AND THUNDERSTORMS ARE EXPECTED TO REDEVELOP AND OVERSPREAD MUCH OF THE AREA THROUGH THE EARLY TO MID AFTERNOON HOURS BEFORE DRIER AIR ADVECTS INTO THE REGION BEHIND THE COLD FRONT. PREVAILING -RA AND CB REMARKS WERE INCLUDED DURING THE PEAK HEATING HOURS WITH PREVAILING MVFR CIGS. I WOULD NOT RULE OUT TEMPORARY IFR CIGS AND/OR MVFR VSBYS BUT THE FEELING IS THAT THIS WILL BE THE EXCEPTION RATHER THAN THE RULE. VFR CONDITIONS ARE EXPECTED AREAWIDE BY 00Z WITH LIGHT NORTH WINDS OVERNIGHT. JOHNSON && .PREV DISCUSSION... /ISSUED 1105 PM CDT FRI SEP 24 2010/ DISCUSSION... MOST OF THE PRECIP ACROSS THE AREA IS CURRENTLY DIMINISHING...AND HAVE ADJUSTED POPS TO REFLECT THE LATEST TRENDS...REDUCING OVERNIGHT POPS ACROSS THE NORTHERN BIG COUNTRY...AND MAINTAINING CHANCE TO LIKELY POPS ACROSS THE WESTERN BIG COUNTRY AND CONCHO VALLEY WHERE SHOWERS AND ISOLATED THUNDERSTORMS CONTINUE. WHILE WE ARE NEAR FORECAST OVERNIGHT LOWS IN SOME PLACES...VERY MOIST LOW LEVELS...AND CLOUD COVER OVERNIGHT WILL LIKELY KEEP TEMPERATURES FROM FALLING TOO MUCH MORE FROM CURRENT TEMPERATURES IN THOSE PLACES. HAVE MADE FEW CHANGES TO THE REMAINING GRIDS. 20 PREV DISCUSSION... /ISSUED 632 PM CDT FRI SEP 24 2010/ DISCUSSION... SEE THE 00Z AVIATION DISCUSSION BELOW. AVIATION... WIDESPREAD SHOWERS WITH A FEW THUNDERSTORMS WILL CONTINUE ACROSS THE BIG COUNTRY THIS EVENING AND HAVE TRENDED TO DEVELOP FARTHER SOUTH ACROSS THE CONCHO VALLEY OVER THE PAST 1-2 HOURS. THIS TREND WILL CONTINUE THROUGH THE EVENING BUT COVERAGE IS EXPECTED TO DIMINISH ONCE WE LOSE DAYTIME HEATING. THE COLD FRONT REMAINS TO THE NORTH OF THE CWA WITH NUMEROUS OUTFLOW BOUNDARIES SCATTERED ABOUT THE REGION. THE MOST PROMINENT BOUNDARY CURRENTLY EXTENDS FROM NEAR MERTZON...TO SAN ANGELO...TO BALLINGER. THIS WILL PLAY HAVOC WITH WINDS NEAR KSJT OVER THE NEXT 1-2 HOURS WITH NORTHEAST WINDS NORTH OF THE BOUNDARY AND SOUTHEAST WINDS TO THE SOUTH. WINDS WILL TAKE ON A GENERALLY EAST TO SOUTHEAST COMPONENT OVERNIGHT AT LESS THAN 10KTS BEFORE BACKING TO THE NORTHEAST ON SATURDAY AS THE MAIN COLD FRONT EVENTUALLY MOVES THROUGH THE AREA DURING THE DAY. SCATTERED SHOWERS WILL BE POSSIBLE THROUGHOUT THE NIGHT AT ALL SITES...FAVORING THE KABI/KSJT/KBBD. PRECIPITATION IS EXPECTED TO INCREASE IN COVERAGE AGAIN BY AROUND 15Z WITH POPS EVENTUALLY SHIFTING TO THE SOUTHERN ZONES BY THE AFTERNOON. LOW CIGS ARE EXPECTED TO DEVELOP AFTER 06Z BUT THE BOUNDARY LAYER MAY BE CONTAMINATED BY THE CONVECTION...KEEPING THE CIGS MORE TEMPORARY THAN PREVAILING. OTHERWISE...FLIGHT RESTRICTIONS WILL BE LIMITED TO LOCATIONS IN AND AROUND THE HEAVIER CONVECTION. JOHNSON PREV DISCUSSION... /ISSUED 400 PM CDT FRI SEP 24 2010/ SHORT TERM... LATEST SATELLITE AND WSR-88D DATA INDICATE SHOWERS ARE CONTINUING TO DEVELOP THIS AFTERNOON...MAINLY ACROSS THE BIG COUNTRY. AT THE SURFACE ACROSS WEST CENTRAL TEXAS...TEMPERATURES ARE MAINLY IN THE MID TO UPPER 80S. A WEAK NEARLY STATIONARY SURFACE COLD FRONT EXTENDS FROM JUST NORTH OF LUBBOCK EAST ALONG AND JUST NORTH OF THE RED RIVER. THE NAM CONTINUES TO BRING THIS WEAK FRONT SOUTH TO NEAR OUR INTERSTATE 10 CORRIDOR BY 00Z THIS EVENING. THIS SOLUTION LOOKS WAY TOO AGGRESSIVE. I BELIEVE THE SHOWER AND THUNDERSTORM ACTIVITY WE ARE SEEING NOW WILL CONTINUE THIS EVENING AND PERHAPS OVERNIGHT. THE BEST RAIN CHANCES WILL BE ACROSS THE BIG COUNTRY TONIGHT...AND BEYOND 9 PM CDT THIS EVENING THE MAIN ACTIVITY WILL BE SHOWERS WITH ONLY ISOLATED THUNDERSTORMS IF ANY. WE DID DISCUSS A FLASH FLOOD WATCH FOR TONIGHT. HOWEVER...WE DECIDED TO CONTINUE WITH NO WATCH AT THIS TIME...MAINLY BECAUSE WE BELIEVE THE SOIL ACROSS WEST CENTRAL TEXAS WILL BE ABLE TO TAKE AN INCH OR TWO OVERNIGHT WITHOUT CAUSING MAJOR FLASH FLOODING. OF COURSE...WE WILL NEED TO WATCH ABILENE...SAN ANGELO...AND OTHER PROBLEM AREAS CLOSELY IF HIGH AMOUNTS OF RAINFALL OCCUR THERE. BUT...WE DO NOT BELIEVE WEST CENTRAL TEXAS IS CURRENTLY UNDER A THREAT OF WIDESPREAD FLASH FLOODING DURING THE NEXT 24 HOURS. FOR TOMORROW...THE NAM BRINGS THIS WEAK FRONT BACK INTO OUR CENTRAL COUNTIES DURING THE AFTERNOON. ALTHOUGH I STILL DO NOT LIKE THIS SOLUTION...I DECIDED TO GO WITH WIND GRIDS WHICH REFLECT A COMPROMISE BETWEEN THE NAM AND WHAT I BELIEVE WILL ACTUALLY OCCUR. AS THE FRONT SHIFTS SLOWLY SOUTH TOMORROW...THE BETTER RAIN CHANCES WILL SHIFT INTO OUR MIDDLE COUNTIES FROM THE BIG COUNTRY. HUBER LONG TERM... WITH AMPLIFICATION OF THE UPPER LEVEL FLOW PATTERN THIS WEEKEND... UPPER RIDGE WILL BE OVER THE WESTERN US...WHILE A CLOSED LOW WILL DEVELOP OVER THE MID-MISSISSIPPI VALLEY WITHIN AN UPPER TROUGH DIVING SOUTH INTO THE MIDWEST. HAVE A CHANCE FOR CONVECTION LINGERING ACROSS THE SOUTHERN HALF OF OUR AREA SATURDAY NIGHT...IN ASSOCIATION WITH WHAT IS LEFT OF AN OLD FRONTAL BOUNDARY. WITH THE DEVELOPMENTS IN THE UPPER LEVEL PATTERN...A STRONGER COLD FRONT WILL SURGE SOUTH ACROSS WEST CENTRAL TEXAS LATE SATURDAY NIGHT/SUNDAY MORNING. THIS WILL END THE RAIN CHANCES...BUT MODEL LOW-LEVEL MOISTURE FIELDS INDICATE SOME POST-FRONTAL CLOUDINESS BEFORE DRIER AIR INFILTRATES WITH CLEARING SKIES FROM THE NORTH SUNDAY AFTERNOON. A COOLER AND MUCH DRIER AIRMASS WILL THEN SETTLE OVER OUR AREA FOR THE EARLY PART OF NEXT WEEK. THIS WILL RESULT IN A LARGER DIURNAL TEMPERATURE RANGE THAN WE HAVE SEEN IN AWHILE. WITH SURFACE HIGH SETTLING SOUTH INTO WEST CENTRAL TEXAS AND WITH GOOD RADIATIONAL COOLING...WILL HAVE A FEW NIGHTS WITH LOWS IN THE 50S ACROSS OUR AREA. A FEW LOCATIONS MAY HAVE A NIGHT OR TWO WITH LOWS NEAR 50 DEGREES. TEMPERATURES WILL BE A FEW DEGREES WARMER FOR THE LATTER HALF OF NEXT WEEK...AS UPPER HIGH SHIFTS EAST INTO THE CENTRAL AND SOUTHERN PLAINS. 19 && .PRELIMINARY POINT TEMPS/POPS...
