SACRAMENTO, Calif. (KTXL) — Widespread, steady rain moved through the Valley Thursday morning as a quick storm pushes through the area.

Some commuters hitting the road in the early morning hours saw heavy downpours.

Some chain controls were in effect as moderate to heavy snow fell over the Sierra.

Chains were required on almost all vehicles on eastbound Interstate 80 from Baxter to the Donner Lake Interchange and westbound from Donner Lake Interchange to Whitmore, Caltrans reported.

Drivers were advised to exercise caution and drive slower to avoid crashes, spinouts and road closures.

“If people do not drive slowly for the weather conditions and drive safely, then there may be incidents that cause the road to temporarily close while we get the road cleared,” said Raquel Borrayo with Caltrans District 3.

Snow in the Sierra is expected to continue falling into Thursday afternoon, but by 5 p.m. FOX40’s Weather Team expects to be done with the current weather system.

Up to 6 inches (15 cm) of snow was reported early Wednesday at Homewood Mountain, Palisades Tahoe and Mount Rose on the southwest edge of Reno, with 5 inches (13 cm) at Heavenly on Tahoe’s south shore and 3 inches (8 cm) at Incline Village on the north shore. About an inch (2.5 cm) was reported in Sun Valley on the north edge of Reno and a half-inch (1 cm) in Carson City.

A Frost Advisory has been issued in the Central Valley for late Thursday night into Friday morning, National Weather Service Sacramento reported.

Temperatures are expected to range from 30 to 35 degrees, with some areas dropping to 28 to 30 degrees early Friday.

“Widespread frost is expected, especially in outlying areas. Protect frost sensitive vegetation,” NWS Sacramento tweeted.

The area will remain dry until Sunday when a significant storm moves in, bringing rain and snow to the area into Tuesday. FOX40’s Weather Team says people should start preparing now for the wet weather, which may mean dedicating the upcoming days off to cleaning leaves out of gutters and storm drains to avoid flooding.
