AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE SAN ANGELO TX 410 PM CDT SAT JUN 18 2011 .UPDATE... WITH THUNDERSTORMS NOW DEVELOPING ALONG THE DRYLINE...WE DECIDED TO ISSUE A SEVERE THUNDERSTORM WATCH FOR MUCH OF THE BIG COUNTRY. THUS...I UPDATED THE ZONE PRODUCT TO HEADLINE THE WATCH AND TO ADD WORDING FOR THE POTENTIAL OF SEVERE THUNDERSTORMS TO THE FIRST PERIOD WORDING. OTHERWISE...NO OTHER CHANGES. HUBER && .PREV DISCUSSION... /ISSUED 350 PM CDT SAT JUN 18 2011/ SHORT TERM... LATEST SATELLITE IMAGERY INDICATE A LINE OF CUMULUS DEVELOPING ALONG A SURFACE DRYLINE EXTENDING FROM FORT STOCKTON TO SWEETWATER TO THROCKMORTON. SOUTH AND EAST OF THIS BOUNDARY...DEWPOINT TEMPERATURES ACROSS WEST CENTRAL TEXAS RANGE FROM AROUND 50 TO THE MID 50S. NORTHWEST OF THE DRYLINE...DEWPOINTS ARE IN THE 30S. ALSO...SURFACE ANALYSIS PLACES A WEAK COLD FRONT ACROSS THE SOUTHERN TEXAS PANHANDLE JUST SOUTH OF LUBBOCK. SHOWERS AND THUNDERSTORMS MAY DEVELOP NEAR THE INTERSECTION OF THIS WEAK FRONT AND THE DRYLINE DURING THE NEXT SEVERAL HOURS. THUS...I DECIDED TO CONTINUE SLIGHT CHANCE POPS FOR MOST OF OUR BIG COUNTRY COUNTIES THIS EVENING. FOR THE REMAINDER OF THE SHORT TERM...HOT AND DRY CONDITIONS WILL CONTINUE TO DOMINATE WEST CENTRAL TEXAS. FORECAST TEMPERATURE DATA FROM THE MEX MOS PRODUCT CONTINUE TO UNDER FORECAST AFTERNOON HIGHS AND CONTINUES A DOWNWARD TREND FOR AFTERNOON HIGHS INTO THE MIDDLE OF NEXT WEEK. WITH THE UPPER-LEVEL FLOW PATTERN BECOMING MORE SOUTHWEST ACROSS TEXAS DURING THE NEXT COUPLE DAY...SEE NO REASON FOR THE 850 THERMAL RIDGE TO NOT EXPAND INTO WEST CENTRAL TEXAS DURING THE AFTERNOON HOURS TOMORROW AND MONDAY. SLIGHTLY MORE CLOUD COVER MAY DECREASE SUNSHINE SOMEWHAT. HOWEVER...TRIPLE DIGIT HIGHS FOR MOST OF WEST CENTRAL TEXAS FOR THE SHORT TERM LOOK BEST. LONG TERM... RAIN CHANCES STILL LOOK SOMEWHAT PROMISING FOR MID TO LATE WEEK. THE GFS STILL BRINGS A WEAK FRONTAL BOUNDARY INTO THE BIG COUNTRY MID WEEK. GIVEN FAVORABLE UPPER-LEVEL SOUTHWEST FLOW...WEST CENTRAL TEXAS MAY FINALLY SEE SOME RELIEF FROM THIS PESKY DRY SPELL.
