Chance of rain Friday; stronger system to arrive Saturday

The Sacramento area saw cloudy skies but no measurable rainfall Thursday, as precipitation from a weak storm system stayed largely to the north.

Areas north of Marysville saw rain, and traces of rain were reported around Vacaville, said Johnnie Powell, a forecaster with the National Weather Service.

Yuba City had recorded 0.11 inches as of 5 p.m. and Oroville, 0.19 inches.

A 40 percent chance of showers was forecast Friday for the Sacramento area, increasing to 80 percent Friday night. But the main body of a stronger storm system expected this weekend won’t arrive until Saturday, Powell said.

The weather service projects a parade of storms next week. The strong system Saturday is expected to bring heavy rain and gusty winds. Showers and possible thunderstorms are forecast for Sunday.

A high temperature of 69 degrees is expected Friday with a high around 65 degrees on Saturday before dropping to around 56 degrees Sunday.

A winter storm watch for the Truckee and Lake Tahoe areas is in effect from Saturday evening through Monday morning. A mix of rain and snow is expected Saturday, turning to all snow late Saturday night and into Sunday morning with another round of snow likely Sunday night. Snow accumulations of 1 to 3 feet are expected above 7,000 feet, with 6 to 12 inches between 6,000 and 7,000 feet.

The National Weather Service warns that snow levels are likely to fall rapidly with roads quickly becoming covered with snow, resulting in slow travel and chain controls. High temperatures in the Truckee and Lake Tahoe areas are expected to be in the mid-50s Friday and Saturday, and around 38 degrees Sunday.
