Snow Later Wednesday into Thursday Morning...

Summary

Dry weather on Tuesday. Showers are possible by Wednesday afternoon. Snow for Wednesday night into Thursday morning. The next storm moves later Saturday into Saturday night. A longer and stronger storm is possible for later Sunday night through Tuesday - Wednesday. Then quieter weather is possible later next week.

Update

Dry Pattern Monday - Tuesday:

Dry weather is expected into Wednesday morning.

Wednesday - Thursday Storm:

Snow showers could reach the pass Wednesday afternoon, but steadier snow is expected from the evening into Thursday morning, and then clearing by Thursday afternoon. Snow levels may start around 6300-6800 ft., and fall below 5000 ft. by early Thursday morning.

That means snow over the pass through the storm. We could see chain controls set up by Wednesday evening from around Kingvale to Donner Lake. They could extend to Blue Canyon through Truckee by Thursday morning. Carry chains and expect some snow and slow travel Wednesday night through Thursday morning. Conditions should improve through Thursday afternoon.

Saturday Storm:

The next storm is expected to reach the Sierra by Saturday afternoon and continue into Sunday morning before clearing out during the day on Sunday. Snow levels could start out around 6500-7000 ft. with snow over the top of the pass through Saturday evening, and then snow levels falling overnight down to around 5000-5500 ft. by Sunday morning.

Expect chain controls to set up by Saturday evening and overnight into Sunday morning. Likely from around Soda Springs to Donner Lake, and possibly a bit longer and lower later Saturday night into Sunday morning. Travel will likely be snowy and slow over the pass until conditions improve on Sunday.

Monday - Wednesday Storm:

Sunday will be a break between storms. Then later Sunday night through Wednesday we could see a longer and wetter storm that could bring significant snowfall to the Sierra. This storm could bring chain controls from Kingvale to Truckee later Sunday night through Wednesday and could cause long delays in return travel from the 3-day weekend.

We'll continue to fine-tune the details all week.

Long-Range:

The active pattern could diminish later next week through the 24th but could become more active again during the last 4-5 days of February.
