KEY MESSAGES

Updated at 121 PM PST Sat Jan 24 2026

- Clear today and tonight with cool overnight temps in the mid-30s inland

- Offshore winds weaken by Sunday morning; light winds then prevail into mid-week

- Slight chance of rain showers late Tuesday/Wednesday AM along coastal ranges and the North Bay. Amounts generally less than 0.1"

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.

AVIATION

(18Z TAFS) Issued at 943 AM PST Sat Jan 24 2026

Satellite imagery this morning is drastically different compared to yesterday, as many areas have clear skies. Stratus and fog lingers in some North Bay Valleys and across the interior Central Coast, with the North Bay clearing in a couple of hours. South, the stratus looks bit thicker so it may take a little while longer to clear, though once it does VFR conditions should prevail across the region. Opted to go a bit more pessimistic for KSTS and have IFR conditions return. LIFR is possible, but opted to not go from VFR to LIFR in the TAF cycle since only the MOS and some hi- res guidance supports this. These models also show some reduced vis in KAPC tonight; however, offshore winds should be stronger there and keep fog at bay.

Vicinity of SFO...Stratus has cleared, leaving SFO with VFR conditions for the TAF cycle. Winds should switch to the north- northeast by late morning or early afternoon, and then become offshore overnight.

SFO Bridge Approach...Similar to SFO.

Monterey Bay Terminals...Clear skies and VFR conditions will prevail. Winds of around 5-10kt will eventually become onshore today for a brief period, with offshore winds returning tonight.

MARINE

(Today through Thursday) Issued at 326 AM PST Sat Jan 24 2026

Moderate to fresh northerly breezes today and tonight. Wave heights continue to subside today. Improving wind and sea conditions will persist through the weekend to mid next week.
