Unsettled weather returns to Northern California as we "fall back" this weekend

Thursday evening weather forecast - Nov. 2, 2023

Changes are ahead through next week as our weather shifts from a mild pattern into a cooler and unsettled one. 

Through Friday, rain will focus mainly across northern portions of the Sacramento Valley into the Pacific Northwest. Most from Chico to the south will stay dry until this weekend.   

The end of the week will stay mild with partly cloudy skies and temperatures slightly above average across the region.   

We'll start noticing the changes as we get closer to Sunday, as rain is in the forecast with breezy winds. We'll have better rain and snow potential as we head into early next week, but a little precipitation will be expected this weekend.  

The Track 

Our track starts to shift further south by the time we get into Saturday. Rain begins to develop across areas north of I-80 late Saturday before tracking to the south heading into Sunday. 

This shift in the pattern will keep rain and cooler temperatures in the forecast through early next week. 

Rainfall Amounts

As far as rain amounts go, this weekend, we're not expecting anything major. Most from the Bay Area to the Sacramento Valley can expect up to a tenth of an inch.

The Sierra will pick up slightly more rain accumulations with a quarter to half an inch expected Saturday through Sunday evening. 

Looking ahead to next week, models are hinting at larger amounts across the Sierra as snow levels drop and more moisture arrives. 

Monday through early Wednesday is when we are tracking to receive more than an inch of snow to our passes, especially to those north of Highway 50. 

Snow Potential

Snow levels remain above 8,000 feet in elevation until temperatures drop on Sunday. 

As temperatures get colder, the rain will change over to snow quickly. The passes could be looking at slick roads, low visibility and chain controls, especially through Tuesday. 

As amounts go, models have not been in alignment yet as we are still five days out. But models hint at 2 to 5 inches of snow possible for the passes, especially across Highway 50 and I-80. 

We are calling Tuesday a First Alert Action Day. Stay with us as we track this over the weekend for any changes to snowfall amounts.
