After several days of sunny skies and record-breaking heat, rain is returning to California.

As a new system moves through the Golden State this week, it’s expected to bring isolated thunderstorms, mountain snow, gusty winds and cooler temperatures, according to the National Weather Service.

The latest forecasts show rain could spread across several parts of California, including Northern California, coastal areas and the Central Valley — with impacts expected in Sacramento, Modesto, Merced, Fresno and San Luis Obispo.

Here’s when rain is forecast to arrive:
