Tomer’s Take: This is a challenging period with mostly dry conditions across the Intermountain West and rain (again) in the Northeast. The main storm track impacts BC/WA/OR/CA, but very little of this moisture survives the trip into the Interior Rockies.
My forecast video:
Current Setup
Water vapor satellite shows an active Pacific storm track aiming at BC/West Coast. But, very little of this moisture survives the trip into the Interior Rockies.
Orange/red = drier air aloft.
Forecast Jet Stream
Trough of low pressure approaches the West Coast.
Cold air remains trapped in Canada with northern branch. Active subtropical jet delivers a storm system to the Intermountain Weather 1/3-1/5.
