Payam Javan: The National Weather Service in San Francisco said the region had light sprinkles Friday morning, and the unrest is anticipated to worsen in the coming days with additional light rain, sporadic thunderstorms, high-elevation snow, and abnormally cold temperatures.
On Sunday, the weather will change as a cold front passes into Northern California, bringing cooler temperatures and the possibility of rain. Highs in the afternoon are expected to be in the upper 50s to mid-60s. The North Bay has the highest chance of rain.
A bitterly cold late-season trough is anticipated to hit the region on Monday and Tuesday, bringing temperatures considerably below normal. The weather service noted that while not all regions will see rain, “everyone will notice the chilly daytime highs and cool to cold overnight lows.”
The trough will pass directly over the Bay Area on Tuesday, bringing more rain than the systems that passed through on Friday and Sunday.
