WHAT A CONTRAST FROM YESTERDAY TO TODAY. WALL TO WALL SUNSHINE
BLANKETS THE BAY AREA AND CENTRAL COAST THIS AFTERNOON. STRONGER

24 HOUR TRENDS ACROSS THE NORTH BAY WITH MANY SONOMA CO SITES
10-20 DEGREES WARMER THAN YESTERDAY.
FOR TONIGHT AND INTO THURSDAY...STRATUS WAY OFFSHORE WILL INCH
CLOSER WITH ADDITIONAL STRATUS DEVELOPING ALONG THE COAST. NOT
EXPECTING A FULL ON MARINE LAYER PUSH, BUT PATCHY STRATUS. MOST

REGION. FOR THURSDAY, AM CLOUDS WILL FADE QUICKLY LEADING TO
ANOTHER SUNNY DAY ACROSS THE REGION. TEMPERATURES WILL NUDGE

THURSDAY NIGHT INTO FRIDAY AS A LITTLE BIT OF RINSE AND REPEAT
WITH SOME PATCHY COASTAL MARINE LAYER CLOUDS AND AFTERNOON
SUNSHINE. TEMPERATURES WILL BE SIMILAR TO THURSDAY: 60S TO NEAR
80 COAST/BAYS AND 80S TO MID 90S INLAND.
STILL LOOKING AT A NOTABLE PATTERN CHANGE OVER THE WEEKEND WITH
REGARDS TO TEMPERATURES. AN UPPER LEVEL LOW/TROUGH CURRENTLY IN
THE GULF OF AK WILL MOVE THROUGH THAT PACNW AND ULTIMATELY CA.
LOWER 500MB HEIGHTS, DEEPER MARINE LAYER, COLDER 850MB TEMPS WILL
YIELD A DROP IN TEMPERATURES ACROSS THE BOARD - ROUGHLY 5-10 DEG
FROM FRIDAY TO SATURDAY. A MORE SUBTLE COOLING TREND WILL CONTINUE
INTO EARLY NEXT WEEK. THE TROUGH WILL ALSO BRING MORE WIDESPREAD
NIGHT/MORNING CLOUDS WITH COASTAL DRIZZLE POSSIBLE. LONGER RANGE
ENSEMBLE GUIDANCE CONTINUES TO SUGGEST A FEW SHOWERS AROUND THE
REGION MONDAY INTO TUESDAY, BUT CONFIDENCE IS GENERALLY LESS THAN
20% AT THIS POINT. IF IT DOES HAPPEN IT WON'T BE MUCH IN THE WAY
OF PRECIP.
