Fog still looks to be the main impact on holiday travel plans locally… things get a little more interesting by the weekend with the potential for cooling, gusty wind and showers, stay tuned 11/23/2025

Also into fog-chilled day time highs season...inland East Bay and North Bay valleys are prone to this as fog lingers into the afternoon. Low 50s Napa, across inland Contra Costa County approaching 3pm. This pattern will likely stick around through Thanksgiving #CAwx 11/23/2025

While not officially into Winter quite yet, our winter mode for fog is underway. Recent rain, clearing skies, light wind are perfect for Central Valley fog and we’ll see dense fog advisories to wrap up the weekend. Things could take a chilly turn toward the end of next week, stay tuned. 11/22/2025

Sideways rain with strong wind at our StormRanger San Bruno Mtn site, as a strong cold front (NCFR) moves through the region. Widespread rain should be mostly east before sunrise but lingering roadway impacts are likely, due to runoff from high rain rates per hour overnight. #CAwx 11/17/2025

11:30 PM radar update: special marine warnings continue, although taking on a bit more of an NCFR look, with radar detected rotation, not quite as strong as before (offshore Marin Co) peak, wind and rain with the line now through 2 AM. #CAwx 11/16/2025

10:30 PM radar update… stronger cells approaching the coast, those curvatures are usually indication of stronger wind gusts. Some special marine warnings might be possible as this moves onshore. #CAwx 11/16/2025

8pm radar update: rain approaching the coast with some lightning at times. Still expecting peak rain rates and strong wind around midnight, followed by scattered showers and a chance of isolated thunder into Monday. 11/16/2025 #CAwx

November rain (🎸) vs. average: true, it is supposed to rain in November (one of the top 4 rain months) but we're running ahead of average and these numbers will certainly leap even more > average this week, thanks in large part to tonight's storm #CAwx 11/16/2025

So far and next: Not your typical rainfall distribution from Saturday into early Sunday morning with top rain totals near San Jose and the South Bay. That area of low pressure near SoCal is lifting east, next storm bringing an intense cold front our way by midnight. 11/16/2025

60-day precipitation departure from normal. Most all states, with a few notable exceptions, are quite dry.

Plan on a stormy finish to the weekend 🚨 increasing wind and rain late evening and overnight as a fast moving but intense cold front moves through. We will likely see some localized runoff issues overnight w/ lingering impacts possible into the Monday morning commute. 11/16/2025

Saturday showers will be followed up by a Sunday night storm. The best rain chances have been across the southern portion of the area as low pressure lifts inland to our south. This will change Sunday night as our next storm and cold front arrives, bringing a boost to wind and rain into early Monday

We’ve talked about it for a few days and now our midweek storm is just around the corner. We’ll see increasing wind late Wednesday with some rain possible at times, more so by evening. But the main wind and rain event will be Wednesday night into Thursday morning. @nbcbayarea.com 11/11/2025
