COMING IN AROUND 10 DEGREES WARMER THAN YESTERDAY...MAXIMUM
TEMPERATURES IN THE AVERAGE MIDDLE 70S INLAND/LOWER 70S ALONG THE

MORNING PRECIPITATION CHANCES. SCATTERED SHOWERS AND ISOLATED
THUNDERSTORMS MAY FORM ALONG AND AHEAD OF A THURSDAY MORNING COLD
FRONTAL BOUNDARY. THIS FRONT WILL TRAVEL ACROSS THE CWA DURING THE
EARLY MORNING HOURS AND BE OFF THE COAST BEFORE NOON. DUE TO THE VERY
PROGRESSIVE NATURE OF THE FROPA...LOW QPF OF NO MORE THAN A QUARTER
TO A HALF OF AN INCH. COOL AIR ADVECTION WILL DROP THURSDAY AFTERNOON
TEMPERATURES BACK DOWN INTO THE BELOW NORMAL MIDDLE 60S...JACKET

MARINE...
ONSHORE WINDS ALREADY 15-20KT OFFSHORE AND HAVE HOISTED THE CAUTION
