11/2 Mountain Weather Update; Teton snow inbound

Tomer’s Take: Three different storm systems loaded with Atmospheric River (AR) moisture hit the PNW/BC through 11/10 with overrunning snow in Banff, MT, and WY. The Tetons are in good position for heavy snow accumulation.

My forecast video:

Current Setup

Water vapor satellite shows all three areas of low pressure lined up.

Atmospheric River

Forecast atmospheric precipitable water shows a dragon’s breath of moisture stretching all the way back past Hawaii. This is the River.

Forecast Jet Stream

A powerful west to east oriented jet acts like a conveyor belt for moisture transport.
