It’s going to look a lot like winter the first week of the New Year.
The National Weather Service said the north state is experiencing a cold start to the week as a weather system from the Arctic lowers temperatures. The NWS expects temperatures overnight into the 30s in Sacramento.
Significant snow could fall Monday and Tuesday, perhaps into the foothills. The Interstate 5 corridor through Shasta County could peak at two feet of new snow above 1,000 feet by Tuesday. There could be a dusting of snow in Redding.
A light dusting of snow could occur around 1,000 feet on Tuesday in the foothills around Sacramento. However, the bulk of snow -- perhaps up to 18 inches -- will be above 3,000 feet elevation in the Sierra Nevada.
Every day in the upcoming week’s forecast has the chance for some precipitation in Sacramento, according to the NWS.
Weather service meteorologists, however, say that details about the week could change. Initial indications are that about a half-inch to an inch of rain could fall in the Sacramento Valley on Wednesday.
December’s rainfall total ended at 3.77 inches, which is about a inch over normal for the month. The total rainfall for the season stands at 9.51 inches, which is 137 percent of normal to Dec. 31.
