While Bay Area residents are already feeling the cooler weather moving through the region, it's about to get even more chilly with a cold snap expected to send temperatures plunging to near freezing next week, forecasters said Friday.

The region should see temperatures in the upper 50s to mid 60s throughout the weekend before they drop Monday into the low 50s, said Brian Mejia, a forecaster with the National Weather Service.

Temperatures will continue to drop and by Wednesday morning many areas in the region will have temperatures dipping to the mid to upper 30s in the overnight to early-morning hours, Mejia said.

There’s also a slight chance of rain in the North Bay on Tuesday morning, he said.
