..DISCUSSION FROM SFOFWFMTR
NEAR TO SLIGHTLY BELOW NORMAL TEMPERATURES AND DRY CONDITIONS ARE
EXPECTED THROUGH THE WEEKEND. A COMPRESSED MARINE LAYER WILL
CONTINUE TO SUPPORT POOR MINIMUM DAYTIME RELATIVE HUMIDITY IN THE
AFTERNOONS ACROSS THE INTERIOR WITH LITTLE TO NO RECOVERY AT NIGHT
IN THE HIGHER TERRAIN. RELATIVELY SPEAKING, THE BAY AREA WILL
REMAIN COOLER WITH A DEEPER MARINE LAYER AND THE CENTRAL COAST WILL
REMAIN HOTTER WITH A SHALLOWER MARINE LAYER. DIURNAL SEA BREEZE IS
EXPECTED IN THE AFTERNOONS AND EVENINGS.
..DISCUSSION FROM SFOFWFEKA
MARINE INFLUENCE HAS JUST STARTED TO INCREASE ACROSS THE AREA AND
WILL CONTINUE TO INCREASE THROUGH THE END OF THE WEEK. HIGH CLOUDS
FRIDAY WILL AID IN THE WARMEST INTERIOR TEMPERATURES PULLING BACK
CLOSER TO 90 WITH RH CLOSER TO 25 PERCENT. MID AND UPPER SLOPE
RECOVERIES WILL ALSO IMPROVE THOUGH REMAIN POOR ON HIGHER PEAKS.
WINDS WILL REMAIN GENTLE AND FROM THE WEST. TROPICAL MOISTURE MOVING
OVERHEAD FRIDAY WILL BRING A VERY SLIGHT (5%) CHANCE OF ISOLATED,
DRY THUNDERSTORMS FRIDAY MORNING AND THROUGH THE AFTERNOON, BUT
SIMPLE HIGH LEVEL CLOUDS AND VIRGA ARE THE MOST LIKELY OUTCOME.
WARMER, NEAR AVERAGE CONDITIONS WILL RETURN SUNDAY AND INTO EARLY
NEXT WEEK.
