WEST CENTRAL TEXAS FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN ANGELO TX
323 PM CDT SUN MAY 26 2002

LARGE COMPLEX OF STORMS LAST NIGHT PRODUCED ENOUGH MIXING TO KEEP LOW
CLOUDS FROM DEVELOPING TODAY. WITH GOOD HEATING ALREADY REACHING
CONVECTIVE TEMPERATURE AT 19Z...AROUND 90 DEGREES. CAP WAS NEAR ZERO.
SATELLITE DERIVED CAPES WERE RUNNING AGAIN 3000 TO 5500 J/KG IN EASTERN
SECTIONS OF THE CWA...SO THREAT OF SEVERE WEATHER WILL EXIST AGAIN TODAY
JUST ABOUT ANYWHERE IN THE CWA.

TRIGGER AND FOCUS OF STORMS TODAY WILL BE LEFT OVER BOUNDARIES FROM
STORMS LAST NIGHT...AND STORMS DEVELOPING OFF HIGHER TERRAIN IN THE
SOUTHWEST MOUNTAINS...THAT MOVE NORTHEAST INTO WEST CENTRAL TEXAS. 700
MB WINDS STRONGER THAN YESTERDAY...EXCEPT FOR OVER NORTHWEST HILL
COUNTRY WHERE THEY ARE LIGHT...SO STORMS SHOULD MOVE FASTER AND REDUCE
THE THREAT OF HEAVY RAINFALL. PUT PARTLY CLOUDY SKIES IN ZONES...HOWEVER
IF ENOUGH CONVECTION DEVELOPS TO THE WEST MAY HAVE SOME CIRRUS OVERCAST
THIS EVENING.

AVN AND ETA MODELS SHOW A WEAK UPPER LOW IN THE 4 CORNERS AREA TONIGHT
MOVING INTO THE TEXAS PANHANDLE MONDAY NIGHT. THIS LOW THEN SLOWLY MOVES
OVER SOUTHERN OKLAHOMA/NORTHCENTRAL TEXAS WEDNESDAY...THEN INTO CENTRAL
TEXAS THURSDAY. THIS WILL PRODUCE A CONTINUING CHANCE OF STORMS THIS
WEEK. UPPER RIDGING GAINS CONTROL BY SATURDAY...SO KEPT SATURDAY AND
SUNDAY DRY.

PRELIMS...
