Winter isn’t done with us just yet. A powerful storm system is expected to produce severe weather for millions of Americans from coast to coast this week, bringing heavy rain and strong winds to California,

The Southern California area has one more day of sunny conditions before a set of storms will bring moderate to heavy rain and snow over the next couple of days, forecasters say. The National Weather Service said a slight chance of rain will develop overnight Monday as the first storm continues to make its way into the region.

Wednesday will end the stretch of sunny, spring-like weather for Northern California as heavy snow, rain and wind are expected.
