...ISOLATED SHOWERS AND THUNDERSTORMS POSSIBLE THIS AFTERNOON AND SUNDAY...

.DISCUSSION...
A WEAK UPPER TROUGH WENT THROUGH THE REGION THIS MORNING WHICH HAS PUSHED
A MAJORITY OF THE INSTABILITY AND MOISTURE EAST OF THE FIRE LOCATION. BUT A
SMALL THREAT CONTINUES FOR THIS AFTERNOON. OTHERWISE ANOTHER WEAK TROUGH HANGS
ALONG THE WEST COAST. THE SOUTHERLY FLOW ASSOCIATED WITH THIS TROUGH WILL ONCE
AGAIN BEGIN TO INCREASE THE MOISTURE AGAIN AS EARLY AS SUNDAY BUT MORE ON MONDAY.
THIS BRINGS AN INCREASE THREAT AND COVERAGE OF STORMS TO THE AREA. WITH THIS WEAK
TROUGH OFF THE COAST...WINDS WILL TEND TO REMAIN SOUTHEAST TO SOUTHWEST
DIRECTION OVER THE FIRE AND GENERALLY TERRAIN DRIVEN FLOW AT THE SURFACE.
