San Francisco, California – Northern California is entering a noticeable pattern shift as above-normal temperatures take hold during the February 7–20 period, offering a stretch of milder, more spring-like weather across much of the region.
According to the National Weather Service Climate Prediction Center, temperatures across Northern California are expected to trend above seasonal averages through mid-February. Coastal and bay-area communities, including San Francisco, Oakland, and San Jose, are likely to see mild daytime highs and comfortably cool nights, while inland areas such as the Sacramento Valley also experience a warming trend.
While temperatures turn milder, the pattern will remain active at times. Pacific systems are expected to move through intermittently, bringing periodic chances for rain across coastal areas and the Bay Area. These systems are not expected to stall, but brief rounds of rain could create slick roads, reduced visibility, and localized ponding during commute hours along Highway 101, Interstate 80, and Interstate 580.
Farther north and east, snow levels in the Sierra Nevada are expected to fluctuate higher during warmer periods, limiting snowfall to higher elevations while allowing rain at lower passes. This could affect travel through mountain corridors during precipitation events, especially where rain falls on existing snowpack.
The milder setup follows weeks of active winter weather across the western United States and signals a temporary break from colder patterns. Transportation officials advise drivers to remain alert during rain events, particularly in urban areas where drainage can be overwhelmed quickly.
Forecasters stress that while this pattern leans warmer and calmer, it does not signal the end of winter. Additional shifts remain possible later in the month. Residents are encouraged to monitor updates as precipitation timing becomes clearer during the February 7–20 period.
