A SW FLOW ALOFT BRING A DRIER AIR MASS INTO CENTRAL CALIFORNIA.
MEANWHILE A SHORT WAVE TROUGH NEAR THE BAY AREA WILL MOVE N

MARINE LAYER AND MODERATE ONSHORE FLOW INTO THE INTERIOR. THUS
EXPECT COOL AND NEAR PERSISTENT TEMPERATURES IN THE VALLEY WHILE
HIGHER MOUNTAIN LOCALES COULD SEE A BIT OF WARMING. GUSTY WINDS

FRIDAY TO A SOUTHERLY DIRECTION ON SATURDAY AND FINALLY TO A
SOUTHEASTERLY DIRECTION ON SUNDAY. THIS SOUTHEASTERLY FLOW WILL

SLIGHT CHANCE FOR THUNDERSTORMS ALONG THE SIERRA CREST SUNDAY INTO
THE FIRST PART OF NEXT WEEK. EXACT TIMING OF THESE THUNDERSTORMS
