Wednesday - Thursday Storm:

The next storm is expected to bring some rain showers by later Wednesday afternoon, and then rain and snow with falling snow levels for Wednesday night into Thursday. Over a foot of snow is possible over the pass Wednesday night, so expect chain controls and slow travel.

Snow levels start up around 7000-7500 ft. and fall to around 4000-4500 ft. by Thursday morning, and then hover around 5000 ft. through the day on Thursday. Chain controls start over the top of the pass and then extend to around Blue Canyon to Truckee by Thursday morning.

The roads likely become wet on Thursday with any scattered snow showers. Watch for slick spots at night with the colder temperatures and scattered snow showers that could coat the roads Thursday night.

Friday - Saturday Storm:

Another storm is expected for Friday into Sunday. The storm is dropping south down the CA coast and will direct moisture at the Sierra Friday into Saturday, with scattered snow showers possible into Sunday.

Snow levels rise up to around 5000-5500 ft. on Friday and then drop to around 4000-4500 ft. Friday night. Then hover around 5000 ft. on Saturday before dropping below 4000 ft. Saturday night, and rising back up to around 6000 ft. on Sunday. 

That means chain controls are likely at some point on Friday and continuing into Saturday, and possibly into Sunday morning. The length will fluctuate as snow levels rise and fall throughout the weekend. Any lulls in the showers during the daytime hours each day could melt the roads enough for chain controls to drop, but any heavier showers could bring them back, especially at night.

Expect slower travel and slick roads at times through the weekend.

Long-Range:

A drier pattern is expected for the first few days of April. Then an unsettled pattern is possible again from the 4th - 8th. We'll keep an eye out for any storms that show up in the forecast for this period.
