SHORT TERM
ISSUED AT 243 AM PDT TUE MAR 10 2026
(TODAY AND TONIGHT)
TODAY WILL BE THE COOLEST DAY THROUGH THE EXTENDED FORECAST. THE
EPAC RIDGE THAT WILL DOMINATE OUR PATTERN FOR THE NEXT WEEK AND
BEYOND WILL CONTINUE TO BUILD TODAY. HOWEVER, A BROAD TROUGH AXIS
EXTENDING FROM THE GREAT BASIN INTO NORCAL INTERACTING WITH THE
BUILDING RIDGE WILL PRODUCE GRADIENT FORCING FOR THE GUSTY NORTHWEST
WINDS ALONG THE COAST, ESPECIALLY FOR THE NORTH BAY AND BAY AREA
COASTLINES, ALONG WITH A TIGHT THERMAL H85 GRADIENT ACROSS
NORCAL. TEMPERATURES ALONG THE COAST WILL BE SLIGHTLY BELOW NORMAL
WITH GUSTY NORTHWEST WINDS THIS AFTERNOON. HIGH TEMPERATURES
INLAND WILL RUN ABOUT 5 DEGREES ABOVE NORMAL FOR MOST LOCATIONS
WITH OCCASIONALLY BREEZY NORTHWEST WINDS. WHILE SURFACE WINDS EASE
THIS EVENING, H85 FLOW WILL BEGIN TO INCREASE AND BECOME OFFSHORE
ONCE AGAIN. WITH LIGHT AND VARIABLE SURFACE WINDS TONIGHT INTO
WEDNESDAY MORNING, ALONG WITH THE DEVELOPING OFFSHORE BOUNDARY
LEVEL FLOW PRODUCING MOSTLY CLEAR SKIES, MORE EFFICIENT
RADIATIONAL COOLING WILL RESULT IN LOWS IN THE 40S AND EVEN UPPER
30S FOR HIGHER ELEVATIONS.
LONG TERM
ISSUED AT 243 AM PDT TUE MAR 10 2026
(WEDNESDAY THROUGH MONDAY)
BY WEDNESDAY AFTERNOON, THE WARMING TREND THROUGH THE REMAINDER OF
THE EXTENDED FORECAST WILL BE IN FULL SWING. HIGHS WILL BE IN THE
70S FOR A MAJORITY OF OUR AREA, SOME 60S ALONG THE COAST AND LOW 80S
IN THE SOUTHERN SALINAS VALLEY. WE'LL SEE MORE WIDESPREAD 80S FOR
THE REMAINDER OF THE WORK WEEK INTO THE WEEKEND WITH 90S IN THE
SOUTHERN SALINAS VALLEY BY SUNDAY, EXPANDING IN AREA BY THE
BEGINNING OF NEXT WEEK. WE'LL SEE WIDESPREAD MINOR HEATRISK SET IN
WEDNESDAY AND PERSIST THROUGH SATURDAY WITH INCREASING AREAS OF
MODERATE HEATRISK SUNDAY AND MONDAY. THE WARM TEMPERATURES WILL
PERSIST THROUGH MUCH OF NEXT WEEK. DETERMINISTIC GUIDANCE IS
BEGINNING TO PICK UP ON SOME OFFSHORE TROUGHING AS THE IMPRESSIVE
DOME OF HIGH PRESSURE MEANDERS EAST WELL BEYOND THE CURRENT FORECAST
RANGE.
