Here's what our weather team says you can expect:

Valley rain

This weekend's weather system has arrived and rain will be steady into Saturday evening in the Valley. The region should see a break in the rain by Sunday mid-morning.

The California Internation Marathon from Folsom to Sacramento on Sunday morning looks cool in the mid-40s, with possible rain showers at the start of the race.

But on Sunday there should be some longer sunny day breaks compared to Saturday. There is a chance for thunderstorms on Sunday afternoon around 4 p.m.

Sierra snow

Snow levels will remain high at or above 7,000 feet in the Sierra on Saturday and lower to 4,500 later in the night.

The Sierra saw a mix of rain and snow in some areas, which caused some traffic delays in some areas earlier Saturday.

As we get into Sunday morning, colder air moves in. Snow levels will drop below 5,000 feet in the morning to about 3,800 feet by Monday morning.
