...NO SVR TSTM AREAS FORECAST...

...SUMMARY...
ISOLATED TO WIDELY SCATTERED THUNDERSTORMS WILL BE POSSIBLE ACROSS
COASTAL AREAS OF CENTRAL AND SOUTHERN CALIFORNIA ON SUNDAY...AND
FROM PARTS OF EAST TEXAS INTO NORTHWESTERN LOUISIANA AND SOUTHERN
ARKANSAS. ISOLATED THUNDERSTORMS MAY ALSO DEVELOP ACROSS CENTRAL AND
SOUTHERN FLORIDA SUNDAY AFTERNOON.

...DISCUSSION...
AN UPPER-LEVEL LOW WILL MOVE SLOWLY SEWD ALONG THE COAST OF CNTRL CA
ON SUNDAY. THUNDERSTORM DEVELOPMENT WILL BE POSSIBLE FROM SOUTHEAST
OF SAN FRANCISCO SEWD TO AROUND LOS ANGELES SUNDAY BENEATH THE
UPPER-LEVEL LOW DUE TO LARGE-SCALE ASCENT AND COLD TEMPS ALOFT.
FURTHER EAST...WESTERLY MID-LEVEL FLOW WILL BE IN PLACE ACROSS THE
CNTRL AND ERN STATES ON SUNDAY. ISOLATED THUNDERSTORM ACTIVITY MAY
DEVELOP FROM EAST TX NEWD INTO NW LA AND SRN AR ALONG A SFC TROUGH
AND GRADIENT OF LOW-LEVEL MOISTURE. THESE STORMS WILL PRIMARILY BE
ELEVATED DUE TO A RELATIVELY COOL BOUNDARY LAYER. A POTENTIAL FOR
ISOLATED THUNDERSTORM DEVELOPMENT MAY ALSO DEVELOP ACROSS THE CNTRL
AND NRN FL PENINSULA AS SFC TEMPS WARM DURING THE DAY. INSTABILITY
SHOULD BE TOO WEAK FOR THE DEVELOPMENT OF SEVERE STORMS ACROSS THE
CONUS ON SUNDAY OR SUNDAY NIGHT.
