Dramatic swing in Bay Area temperatures on the way

Warm weather in the Bay Area should continue throughout Wednesday before a cooling trend sends temperatures plunging 10 to 20 degrees throughout the region later this week, forecasters said Wednesday.

On Wednesday, hot weather seen earlier this week will continue with temperatures approaching 90 degrees in parts of the North Bay and inland East Bay, said Suzanne Sims, a meteorologist with the National Weather Service in Monterey.
