SHORT TERM
ISSUED AT 121 PM PST SAT JAN 24 2026
(THIS EVENING THROUGH SUNDAY)
GENERALLY FAIR WEATHER ACROSS THE BOARD TODAY. TEMPERATURES
THIS AFTERNOON ARE ABOUT 10-20 DEGREES WARMER THAN 24 HOURS AGO
THANKS TO TODAY'S LACK OF TULE FOG AND STRATUS. IN FACT, THE ONLY
CLOUD COVER VISIBLE ON SATELLITE IS A BIT OF STRATUS OFF THE COAST
OF BODEGA BAY AND SOME PATCH TERRAIN-INDUCED CU ALONG THE BIG SUR
COAST. TEMPERATURES ARE EXPECTED TO BE A BIT CHILLIER TONIGHT DUE
TO THE LACK OF CLOUD COVER. SUNDAY MORNING LOWS WILL RANGE FROM
THE MID-30S (INTERIOR) TO LOW 40S (COASTAL). THE ONLY OTHER
NOTABLE MENTION IN THE SHORT TERM IS THAT WE'LL HAVE ONE MORE
NIGHT OF BREEZY OFFSHORE WINDS ALONG INTERIOR RIDGETOPS BEFORE THE
LOW PRESSURE SYSTEM RESPONSIBLE (PART THE SAME ONE WREAKING HAVOC
ON THE CENTRAL AND EASTERN US CURRENTLY) MOVES OUT AND IS REPLACED
LARGELY BY ZONAL FLOW ALOFT. THIS WILL RELAX SURFACE PRESSURE
GRADIENTS AND CAUSE ANY OFFSHORE WINDS TO DIMINISH AND BECOME
LIGHT, OR EVEN LIGHT ONSHORE IN SOME LOCATIONS BY SUNDAY
AFTERNOON.
LONG TERM
ISSUED AT 121 PM PST SAT JAN 24 2026
(SUNDAY NIGHT THROUGH NEXT FRIDAY)
WITH MOSTLY BENIGN CONDITIONS THROUGH THE EARLY WEEK, WE'LL JUMP
TO SUNDAY WHEN A WEAK UPPER LEVEL SHORT WAVE TROUGH IS PROGGED TO
MOVE OVER THE REGION. THIS WILL BRING A SLIGHT CHANCE OF RAIN TO
THE AREA. HOWEVER, BASED ON THE MOST RECENT FORECAST UPDATES IT
SEEMS LIKE THIS MAY BE LIMITED TO COASTAL RANGES AS WELL AS THE
NORTH BAY. AMOUNTS ARE VERY SLIM AT A FEW HUNDREDTHS OF AN INCH
FOR MOST AND UP TO A TENTH OR TWO FROM THE GOLDEN GATE NORTHWARD.
BY NEXT FRIDAY, SOME MODEL GUIDANCE IS ADVERTISING ANOTHER CHANCE
FOR RAIN, BUT THERE IS CONSIDERABLE UNCERTAINTY AT THIS POINT TO
TALK ABOUT ANYTHING SPECIFIC.
