How much rain is headed to Sacramento this week?

Sacramento’s sunny weekend will end with a drizzle, according to the National Weather Service.

A weak system is moving into the region Sunday afternoon, dropping some light rain on the city overnight and lingering into Monday morning. NWS meteorologist Cory Mueller said to expect less than a quarter inch.

The coastal mountain range and the northern part of the state will see the biggest snow impact, but Interstate 80 and Donner Summit should see 1 or 2 inches, Mueller said.

After things dry out Monday afternoon, Tuesday is expected to stay clear.

“Our next system moves in on Wednesday,” Mueller said. “That one looks a little heavier.”

Most of the rain will hit Wednesday, depositing anywhere from a half-inch to an inch of rain on Sacramento. Some showers may continue into Thursday, he said.

Donner Summit could see up to a foot of snow and higher elevations could get more than that.

“So a little more snow and a little more rain is expected with the second system,” Mueller said.
