The Northeast could see two storm systems. My mountain weather forecast video 3/11: Current Setup Water vapor satellite shows the Pineapple Express in full swing. Forecast […]

Snow forecast through 3/19

Tomer’s Take: The current atmospheric river (AR) continues through 3/11 then fades. The 2nd moderate to strong intensity AR surge occurs 3/13-3/15. Beyond 3/15 there is one additional storm systems but it’s not AR related. Current Setup Water vapor satellite shows the Pineapple Express.

Pineapple Express, High Snow Levels, Deep Totals

Tomer’s Take: Two atmospheric river surges will push the rain/snow line to 7,000-8,500ft in the Sierra. The biggest snow totals occur above this level. Heavy overrun snowfall occurs in UT, CO, WY.
