Tomer’s Take: Northeast storm system remains in question. Western ridge starts to weaken with moisture sneaking through on 11/22.
- Intensity and track of potential Northeast storm system remains uncertain with inconsistent data.
- Moisture breaks through Western ridge on 11/22.
- Larger pattern change 11/24-12/1 with trough replacing ridge and higher chances for snow.
Infrared satellite shows the Western ridge and next low pressure that will push moisture through the ridge into the PNW/BC.
Northeast Storm System?
Forecast jet stream valid 11/25 continues to show a large dip in the jet stream. What happens after this is still in question.
Snowfall forecast contrast: Yesterday (11/20) afternoon versus today (11/21). Talk about inconsistent data. Pull the slider back and forth:
Western Ridge Breaks Down
Forecast jet stream valid 11/29. The high pressure ridge is gone and replaced by a large trough. This would support colder air and widespread snow across CA, UT, CO, WY, ID MT, PNW, BC.
Forecast radar/satellite valid 11/21-11/26.
Forecast snow totals (inches) valid 11/21-11/23.
Forecast snow totals (inches) valid 11/24-11/29.
