AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE SAN ANGELO TX
714 PM CDT THU MAY 13 2004

.UPDATE...
UPDATING THE FORECAST FOR NEWLY ISSUED SEVERE THUNDERSTORM WATCH...
WHICH COVERS 5 OF OUR SOUTHERN COUNTIES UNTIL MIDNIGHT. SEVERE
THREAT SHIFTING SOUTHWARD. COLD FRONT ADFANCING SSE TOWARD OUR
SOUTHEASTERN COUNTIES. COULD SEE SOME POST-FRONTAL DEVELOPMENT
TONIGHT...ESPECIALLY IN OUR EASTERN COUNTIES. SO CARRYING AN EAST TO
WEST POP GRADIENT.

&&

.PREV DISCUSSION...
NOT MUCH TIME DUE TO SEVERE WEATHER...STORMS DEVELOPED ALONG COLD
FRONT ACROSS THE BIG COUNTRY...AND ALSO OVER THE HEARTLAND AND
EASTERN CONCHO VALLEY IN RESPONSE TO A WESTWARD MOVING OUTFLOW
BOUNDARY FROM EARLIER ACTIVITY IN CENTRAL TEXAS. OUR THINKING IS THAT
STORMS ALONG FRONT WILL CONTINUE TONIGHT AS THE FRONT SAGS SOUTHWARD.
DRY LINE CURRENTLY NEAR SAN ANGELO...BUT BELIEVE IT WILL REMAIN
STATIONARY OR POSSIBLY MOVE BACK WEST A BIT UNTIL UPPER LEVEL SYSTEM
OUT WEST GETS CLOSER. &&

.SJT WATCHES/WARNINGS/ADVISORIES...
SEVERE THUNDERSTORM WATCH UNTIL MIDNIGHT FOR SCHLEICHER...SUTTON...
