Active early November pattern including California

Tomer’s Take:

• High pressure rebuilds for a few days (10/28-10/31) across the West.
• The next trough digs further south/west 11/1-11/5 and looks to include California.
• This could mean snow, colder temps, and very strong wind across the West.

Current Setup

Visible satellite shows additional low pressure systems lined-up in the north Pacific. They will help build and then potentially cuts-off a trough of low pressure over California on/around 11/3/2022.

11/1-11/5

A large trough develops, moves into California, and potentially cuts-off. Below is the forecast mid-atmosphere pressure anomalies valid 11/2-11/3.

Notice the big dip in the jet stream over California on 11/3. This pattern would generate very strong wind in CA, NM, and CO.

Forecast Timing

Forecast radar/satellite valid 10/27-10/31.

Forecast Snowfall

Forecast snow totals (inches) 11/1-11/5.
