Area forecast discussion, Jun 26, 9:05 PM CDT, 7 hours 3 minutes before
WEST CENTRAL TEXAS FORECAST DISCUSSION NATIONAL WEATHER SERVICE SAN ANGELO TX 905 PM CDT WED JUN 26 2002 WAS TEMPTED TO CUT POPS FOR TONIGHT...BUT MCS STILL HAS PRETTY COLD CLOUD TOPS...HAS SHOWN SIGNS OR WARMING (ALA SUNSET)...BUT LEADING EDGE IS ONLY 100 MILES FROM THE BIG COUNTRY...SO WILL NOT MAKE ANY CHANGES TO THE CURRENT FORECAST. AFTERNOON DISCUSSION SCATTERED THUNDERSTORMS CONTINUE TO DEVELOP IN THE TROPICAL AIR MASS ACROSS CENTRAL AND EAST TEXAS. LIFT BEING PROVIDED BY DAYTIME HEATING AND A WEAK UPPER LOW ACROSS NORTHEAST TEXAS. NOT MUCH GOING ON ACROSS WEST CENTRAL TEXAS...AS WEAK SUBSIDENCE ON THE WEST OF THE UPPER LOW HAS SO FAR BEEN STRONG ENOUGH TO KEEP CONVECTION FROM DEVELOPING. MOISTURE NOT A PROBLEM...WITH SURFACE DEWPOINTS HOLDING IN THE 60S AND 850 MB DEWPOINTS IN THE MID TEENS. ALOFT...WEST CENTRAL TEXAS STILL SANDWICHED BETWEEN A LARGE UPPER HIGH OFF TO THE WEST AND THE LOW OFF TO THE EAST...PROVIDING NORTHERLY FLOW ALOFT. DESPITE THE SUBSIDENCE...STILL THINK A FEW SHOWERS AND THUNDERSTORMS WILL EVENTUALLY DEVELOP THIS EVENING ACROSS THE AREA. WILL SEE MORE CONCENTRATED ACTIVITY DEVELOP FARTHER NORTH ALONG AN MCV AS IT DROPS INTO OKLAHOMA. BIGGEST QUESTION IS WITH RELATIVELY WEAK LOW AND MID LEVEL FLOW...HOW FAR SOUTH WILL THE MORE CONCENTRATED ACTIVITY MOVE BEFORE STARTING TO WEAKEN AND DISSIPATE. THINK AT LEAST SOME REMNANT MID LEVEL SHOWERS WILL SURVIVE AND WILL LET CURRENT CHANCE POPS CONTINUE FOR LATE TONIGHT AND THURSDAY MORNING. AIR MASS REALLY DOESNT CHANGE MUCH THROUGH THE WEEKEND...AND HIGH DOESNT LOOK LIKE IT WILL BUILD IN STRONG ENOUGH TO COMPLETELY CAP THINGS OFF FOR A FEW MORE DAYS...SO WILL CONTINUE WITH AT LEAST ISOLATED SHOWERS AND STORMS THROUGH SUNDAY. PRELIM NUMBERS... ABI 070/093/071/093 4322 SJT 070/095/071/094 3322 JCT 071/093/071/093 2322 .SJT...NONE.
