Pattern through December 1

Tomer’s Take: Snow is sneaking through the Western Ridge 11/23-11/24 with a larger pattern change after 11/25. Current Setup Two inches of new snow is reported at Jackson Hole this morning from the “sneaker low pressure”. This snow is headed for the Central and Northern Mountains of Colorado next. Infrared satellite shows the low pressure […]

Snow forecast next 8 days

Tomer’s Take: Northeast storm system 11/25-11/26 trending much weaker with possible 2nd storm system 11/27-11/28. Current Setup Infrared satellite shows two storm systems that degrade the high pressure ridge. The first low sneaks through 11/22-11/24. The 2nd low has a more a more profound effect across the West on/after 11/25. Northeast Storm System What a […]

Northeast uncertainty; Western Ridge breaks down

Tomer’s Take: Northeast storm system remains in question. Western ridge starts to weaken with moisture sneaking through on 11/22. Current Setup 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 […]

Northeast storm system; Thanksgiving Pattern

Tomer’s Take: This is an afternoon update with new numbers for the Northeast. It assumes a stronger storm system. Current Setup Infrared/visible satellite shows the storm track, Western high pressure ridge, and amplifying low pressure systems that will eventually displace the high. Afternoon Update: New Numbers for East This assumes a stronger East Coast storm […]

East/West see-saw through Thanksgiving

Tomer’s Take: Current Setup Infrared satellite shows the robust ridge over the PNW/BC/AK and ridge amplifiers to its West over the NPAC. This also creates the see-saw jet pattern with large trough over the East. Thanksgiving Pattern High pressure remains strong through 11/24 with jet axis bending far north into Canada. This leaves most of […]

Thanksgiving Pattern: East and West

Tomer’s Take: Current Setup Infrared satellite shows the storm track, fast N-S jet flow with cold front, and robust PNW high pressure ridge. Thanksgiving Pattern Forecast jet stream flow on Thanksgiving 11/24 shows the shifting pattern with the jet axis bending far to the north. Some moisture feeds into the PNW/BC/Banff. The trend is for […]

Snow forecast through Thanksgiving

Tomer’s Take: Current Setup Infrared satellite shows the storm track, robust Eastern Pacific high pressure ridge, and strong cold front racing through MT, WY, CO on a fast N-S jet. Thanksgiving Pattern Shift Forecast jet flow valid 11/18 shows the robust PNW high pressure ridge and fast N-S jet flow through MT, WY, CO. Forecast […]

Snow forecast next 8 days

Tomer’s Take: No big storm cycles for the West until on/after 11/21. Current pattern includes high pressure ridge over PNW/BC/CA through 11/20. This is an anomalously strong Eastern Pacific high pressure ridge. Fast N-S jet flow favors Banff, MT, WY, CO, NM for light snow accumulation with cold fronts. Next front races north to south […]

Pattern shift on/after 11-21

Tomer’s Take: PNW/Western BC/CA stay mostly dry through 11/20 with high pressure ridge. Then the pattern shifts on/after 11/21 as the high gets dislodged and lower pressures move into the PNW/BC with a powerful jet. Between 11/14-11/21 the Intermountain West stays active with fast-moving north to south cold fronts but only light snow accumulations. This […]

Who’s favored this week for best snow?

Tomer’s Take: There are no big storm cycles on the immediate horizon for the West. This week favors the Intermountain West including MT, WY, CO, NM. Total snowfall next 8 days is 10″ or less for all resorts in this grouping. Beyond 11/20, the PNW turns more active as high pressure slides east and a […]
