SACRAMENTO (CBS13) – Thunder and lightning may be in the cards for parts of the valley on Wednesday as an offshore weather system makes its way through the region, a National Weather Service forecaster said.

A storm passed through the Stockton-Manteca-Modesto area around 8 a.m. Wednesday, CBS13 meteorologist Laura Skirde said. CBS viewers reported rain and hail in Modesto and Stockton.

More storm activity off the coast is making its way inland, and other parts of the valley could see thunderstorms and light showers throughout the day.

A red flag warning indicating high fire danger has been issued for much of Northern California from 5 p.m. until 11 a.m. Thursday. Dry conditions, gusty winds and considerable lightning strikes with very little rain associated with them could ignite more wildfires, the National Weather Service warned.

Despite the September sprinkles, temperatures will still heat up, with Sacramento expected to reach the low 90s.
