Cold Temperatures, Maybe Even Frost To Hit The Bay Area This Week

Bay Area residents might have to bundle up this week as a cold-weather front brought a change to colder temperatures Sunday night, a National Weather Service forecaster said.

A “fast-moving” low pressure system is developing over the Pacific Northwest and is heading south, forecaster Logan Johnson said today.

The front brings the possibility of the season’s first frost in North Bay valleys, where temperatures could drop into low to mid 30s Tuesday through Thursday nights, Johnson said.

Low temperatures in the San Francisco area are expected to be in the upper 40s, with highs in the upper 50s, according to the Weather Service.

“Unfortunately for us, there is not a lot a moisture associated with the system,” Johnson said.

High elevations in the South Bay have the highest chance of rain, he said.
