WEST CENTRAL TEXAS FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN ANGELO TX
317 PM CDT SAT MAY 26 2001

THUNDERSTORM COMPLEX WHICH MOVED THROUGH EASTERN COUNTIES OF THE FORECAST
AREA LATE LAST NIGHT IS NOW LOCATED OVER SOUTHEAST TEXAS.  AN OUTFLOW
BOUNDARY FROM THESE EARLIER STORMS APPEARS TO BE LOCATED FROM JUST WEST OF
JUNCTION TO NEAR SAN ANGELO.  SATELLITE SHOWING CUMULUS STARTING TO FORM
NEAR THE BOUNDARY...WITH LAPS ANALYSIS SHOWING CAPES OF NEAR 3000 OVER
EASTERN COUNTIES. WITH FURTHER HEATING OVER THE NEXT FEW HOURS...WE MAY SEE
A FEW STORMS DEVELOP NEAR THE BOUNDARY...WITH ISOLATED SEVERE POSSIBLE PER
DAY 1 OUTLOOK FROM SPC.

THE SLIGHTLY BETTER CHANCE FOR THUNDERSTORM DEVELOPMENT THIS EVENING WILL BE
OVER NORTHWEST TEXAS IN THE VICINITY OF A COLD FRONT/DRYLINE AS A WEAK UPPER
SHORTWAVE MOVES DOWN INTO NORTHWEST TEXAS. THESE STORMS SHOULD MOVE
SOUTHEASTWARD AND CONTINUE INTO THE NIGHT WITH A STRONG LOW LEVEL JET...AND
MAY CLIP THE BIG COUNTRY COUNTIES LATE TONIGHT.  WILL KEEP SLIGHT CHANCE OF
PRECIP OVER NORTHERN AREAS THROUGH THE NIGHT BASED ON THIS SCENARIO.

FOR TOMORROW...WEAK RIDGE MOVING A LITTLE FURTHER EASTWARD ACROSS THE AREA
WILL HELP STRENGTHEN THE CAP...KEEPING STORMS FROM DEVELOPING SUNDAY
AFTERNOON/EVENING.  WILL SEE WARM AND DRY CONDITIONS CONTINUE TROUGH
MEMORIAL DAY.

IN THE EXTENDED...THE UPPER LOW OVER THE GREAT LAKES FINALLY PUSHES OFF TO
THE NORTHEAST...WITH A TROUGH DEVELOPING OVER THE SOUTHWEST.  THIS TROUGH
APPROACHES WEST TEXAS BY THE MIDDLE OF NEXT WEEK WITH A WEAK COLD FRONT
PUSHING THROUGH ON WEDNESDAY.  WILL SEE A SLIGHT CHANCE OF PRECIP THROUGH
FRIDAY WITH DRY CONDITIONS 4RETURNING ON SATURDAY.
