Weak storm Monday, strong storm to end the week in Northern California

Minimal impacts are expected with the Monday storm but the second system, set to move in on Thursday, will bring major impacts to the Sierra.

SACRAMENTO, Calif —

The persistent pattern of wet weather will continue this week with two separate storm systems bringing more rain and snow to the region. 

Northern Californians were treated to a warm, spring-like weekend before temperatures drop back below normal by Monday. 

Sacramento reached 70 degrees on Saturday for the first time this February. Temperatures on Sunday will be in the upper 60s, well above the average high of 64 degrees for late February. This month has been slightly above average in temperature, clocking in at 0.9 degrees above average as of February 25.

The pattern change back towards cooler, wetter weather will kick off with a weak system of low pressure on Monday.

This system has continued to trend down in how much rain and snow Northern California can expect. Rain chances will be highest in the foothills and San Joaquin Valley but scattered showers are expected throughout the region from early Monday morning through the evening.

Less than a tenth of an inch is expected for most valley locations with many areas likely missing out on any measurable rain. 

Snow levels will begin around 5,500-6,500 feet, lowering to 4,500-5,000 feet by Monday night and totals will be on the lighter side with 4-10 inches expected. 

A Winter Weather Advisory is in effect through 4 a.m. Tuesday. 

The main weather story this week will be the introduction of a strong trough of low pressure dropping down from the Gulf of Alaska. 

Although some uncertainty remains in rain and snow totals, this storm has the potential to be the biggest snow producer yet this winter. Several feet of snow are expected through Sunday, along with a high chance of foothill snow. 

Snow levels are currently forecast to get as low as 2,000 feet by Saturday night.
