Forecast remains on track with temperatures Wednesday peaking around 10-20 degrees above normal across our area. A high amplitude trough well offshore will slowly make progress toward the California coastline through the remainder of the work week into the weekend. We'll see subtle midlevel height falls with slight decreases in thickness values leading to a gradual cooling trend Thursday through Saturday back down toward seasonally average temperatures. A slight chance for light rain enters the forecast Sunday evening with little to no impacts expected area wide. However there will be a number of outdoor events occurring Sunday, people should be prepared for cooler temperatures from increasing cloud cover and a slight chance of shortlived light rain.

High pressure remains firmly in control of the synoptic pattern over the Western United States today. This has resulted in mostly clear skies throughout the majority of the San Francisco and Monterey Bay regions. Lingering Tule Fog is evident on GOES-West imagery this early afternoon, confined to portions of far interior Contra Costa County along the Delta. Most communities will wrap the day up with about 2 to 5 deg F of warming compared to Monday. Exception to this will be the interior East Bay. For Wednesday, several locations will be within a few degrees of daily records for February 4. Official forecast for San Jose Airport tomorrow is 74 deg F (record is 76 deg F), Salinas Airport 79 deg F (record of 80 deg F), and Monterey Airport 77 deg F (record of 77 deg F).

Pleasant and dry conditions will continue through the work week before the West Coast ridge gets undercut by a weak upper-level low off SoCal and Baja California. This will promote the beginning of a cooling trend around Friday that will last into the weekend.
By late weekend and into next week, ensemble guidance advertises the arrival of a progressive longwave trough to the West Coast, introducing something we haven't seen in a several weeks: rain. There has been a gradual delay with onset of rain chances. Previous forecast packages have noted arrival of rain as soon as early Sunday morning for coastal Sonoma and evening for the Central Coast. The NBM has continued this onset delay with the slight chance of rain now scheduled to arrive to the North Bay closer to mid-day Sunday and the Central Coast late evening Sunday (i.e., pushed back by ~6 hours). Still, the total rainfall amounts appear to remain very light at this time. Some breezy winds may be associated with this system on Monday.
(06z TAFS) Issued at 931 PM PST Tue Feb 3 2026
VFR conditions prevail across the region barring some haze at LVK and a thin layer of radiational fog at STS. Through the night, Tule Fog impacts should develop in the far interior East Bay, with a low possibility for impacts to APC. Meanwhile, radiational fog and stratus may develop in the southern side of San Francisco Bay, but impacts to the main terminals are very low confidence. High resolution modeling is suggesting that the stratus at STS might linger longer than the current TAF forecast, resulting in low confidence in the clearing time Wednesday morning. Winds will remain in a generally offshore pattern, with gusty winds possible in the interior terminals Wednesday afternoon as a light onshore breeze develops at the immediate coastal regions.
Vicinity of SFO, Some high resolution guidance is developing stratus in the southern end of San Francisco Bay early Wednesday morning, but confidence in impacts to the terminal is low and the TAF remains VFR throughout. If stratus does form, greatest chance for impacts is around 14-18Z. Light southeast winds continue overnight through Wednesday morning before a light onshore breeze resumes in the afternoon.
SFO Bridge Approach, Similar to SFO.
Monterey Bay Terminals, VFR through the TAF period. Drainage winds overnight with a moderate breeze at SNS, with light onshore flow developing Wednesday afternoon.
(tonight through next Monday) Issued at 850 PM PST Tue Feb 3 2026
Light winds and seas continue through Wednesday with stable high pressure over the region. Moderate northwest breezes and building seas will cause a return of rough seas late Thursday through Saturday. Northwest winds will increase on Sunday ahead of an incoming cold front dropping down from the Pacific Northwest.
