A strong storm moves in later Wednesday night into Thursday night. Another storm moves in Saturday lasting into Monday. Quieter weather is possible starting Tuesday, at least for a few days.
Wednesday will be dry with no weather-related travel issues expected.
Wed Night - Thursday Storm:
The next storm moves into the Sierra around 12-2 AM Thursday and possibly lasts into Thursday night before clearing Friday. Snow levels look to start below pass level around 5000-5500 ft. and fall below 2000 ft. Thursday night. This storm could bring 1-2+ feet of snow to the northern Sierra.
Be prepared for chain controls and slow driving starting Thursday morning and lasting into Friday morning before conditions start to improve, briefly. Chain controls could start around Blue Canyon to Truckee, and then lower quite a bit Thursday night, maybe down below Colfax all the way to the NV state line. Gusty winds could create white-out conditions at times.
Friday we should see clearing and the roads improving through the day, but likely starting the day with slow travel and chain controls until the roads start melting off.
Saturday - Monday Storm:
Saturday we could see snow from the next storm move in by afternoon and it may continue all the way into Monday night before clearing by Tuesday. Snow levels could start out back up between 5000-6000 ft. into Sunday and then fall to around 4000-5000 ft. Sunday night.
Be prepared for another round of winter driving, slow travel, and chain controls if you plan to travel through the Sierra from Saturday through Monday. The roads should start to clear off on Tuesday.
We could see a break in the storms Tuesday through next Thursday the 8th. The next storm isn't forecast to move into CA until around the 9th, but that could change.
