Atmospheric River might return

Tomer’s Take: Three storm systems are lined-up for the West through 3/14. Plus, a weak to moderate intensity atmospheric river (AR) is possible 3/10-3/12 with heavy snow accumulation. My snow bullseyes are the Sierra and Wasatch.

Kirkwood is reporting 15″ in the last 24 hours.

Mammoth Mountain is reporting 12-14″ in the last 24 hours.

Alta, UT is reporting 26″ in the last 24 hours. Season total is now 619″!

My mountain weather forecast video 3/5:

Forecast Pattern

Forecast jet stream valid 3/11. Notice the powerful jet stream slamming into the Sierra. This is a possible atmospheric river setup.
