...NO SVR TSTM AREAS FORECAST...

...SUMMARY...
SHOWERS AND THUNDERSTORMS ARE EXPECTED FROM SOUTHERN TEXAS THROUGH
THE CENTRAL GULF COAST STATES SUNDAY.

...TEXAS THROUGH THE CENTRAL GULF COAST AREA...

SOUTHERN-STREAM CUTOFF UPPER LOW WILL BEGIN TO ACCELERATE THROUGH
NORTHERN MEXICO LATER SUNDAY APPROACHING SOUTH TEXAS LATE SUNDAY
NIGHT IN RESPONSE TO AMPLIFICATION OF AN UPSTREAM TROUGH OVER THE
NORTHERN ROCKIES. A FRONT WILL PERSIST FROM SOUTH TEXAS THROUGH THE
GULF COAST AREA. THE FRONT WILL MOVE SOUTHWARD THROUGH DEEP SOUTH
TEXAS SUNDAY AS CYCLOGENESIS COMMENCES OVER THE WESTERN GULF IN
RESPONSE TO FORCING FOR ASCENT ATTENDING THE SOUTHERN-STREAM
SHORTWAVE TROUGH. THE EASTERN EXTENSION OF THIS BOUNDARY WILL REMAIN
QUASI-STATIONARY ALONG THE GULF COAST AREA. WIDESPREAD ELEVATED
SHOWERS AND THUNDERSTORMS WILL PERSIST WITHIN A BROAD ZONE OF
ISENTROPIC ASCENT ALONG AND NORTH OF THE FRONTAL ZONE FROM SOUTH
TEXAS THROUGH A PORTION OF THE GULF COAST STATES. A SMALL WARM
SECTOR MAY MOVE INLAND ACROSS SOUTHERN LOUISIANA. HOWEVER...SEVERE
THREAT SHOULD REMAIN LIMITED DUE TO TENDENCY FOR THE LOW-LEVEL JET
TO SHIFT NEWD AWAY FROM THIS REGION DURING THE DAY IN RESPONSE TO A
PROGRESSIVE SHORTWAVE TROUGH MOVING THROUGH THE OH VALLEY.
