, Issued at 136 PM PST Mon Jan 26 2026 (This evening through Tuesday)
Mostly clear skies across the board today under a building ridge of high pressure. Many locations running about 4-6 degrees warmer than 24 hours ago, largely in part to the lack of cloud cover today. Winds remain light and variable with the exception of breezy offshore winds in the vicinity of the Delta. A weakening shortwave trough approaches the West Coast late Tuesday, bringing increased cloudiness ahead of rain chances overnight.

Rain chances overnight Tuesday do exist, but very limited on who will actually get measurable precip. With the system weakening and lifting toward the NE, most rain will likely only fall in the North Bay (0.05" to 0.25"), with lighter or even trace amounts across the SF Peninsula and immediate SF Bay region. Interior East Bay, South Bay, and areas south of Watsonville will likely only see drizzle at best. This all comes to an end by the middle of Wednesday morning, then ridging builds back in aloft promoting dry weather and temps near to slightly above average. The next mention of rain looks to be around the Sunday timeframe, but uncertainty is still high at this point.
