Tomer’s Take: A powerful low pressure and jet stream deliver feet of snow to the West 11/7-11/10. Forcing ingredients include a 150mph jet stream/streak, strong orographics, and weak atmospheric river (AR) contribution. Peak snowfall times by mountain range are listed below. Current Setup Infrared satellite shows the moisture channel, storm track, and low pressure systems […]

Tomer’s Take: Snow continues to fall across the Intermountain West with a WNW flow and powerful jet stream. This is associate with storm #2. Storm #3 is riding the heels of storm #2. Storm #3 delivers the best orographics and possible weak atmospheric river contributions to the Sierra and Interior Mountain West. Period of maximum […]

Tomer’s Take: Storm #2 is currently generating snow and strong wind in the PNW, ID, MT, WY, and UT. Storm #3 is riding the jet on the heels of storm #2. Overall, the atmospheric river (AR) intensity remains in question for the Sierra. It looks brief and weak. I decreased snow totals a notch in […]

Tomer’s Take: As storm #1 departs CO/NM, storm #2 and storm #3 are lined-up. Each could deliver brief atmospheric river (AR) contributions. Each could deliver proper orographics with big snow totals including the Sierra and interior Rockies. Current Setup Water vapor satellite shows the storm track and atmospheric river setup pointed directly at the PNW/BC. […]

Tomer’s Take: Three different storm systems likely through 11/10. Storm #1 is currently sliding through UT, AZ, NM, and CO. Storm #2 is part of an Atmospheric River (AR) that nails the PNW/BC then potentially the Sierra. Storm #3 follows a similar track to Storm #2 and delivers another round of heavy snow to the […]

Tomer’s Take: Three different storm systems are lined-up between 11/2-11/10. Storm #1 is currently sliding south through CA and will take a southern track benefitting the southern tier of the Rockies. Storm #2 takes a more central/north track favoring the Central and Northern Rockies. Storm #3 is similar to storm #2. Big snow totals are […]

Tomer’s Take: Now it looks like three storm systems are lined-up between 11/1-11/10. This includes a brief atmospheric river for the PNW between 11/3-11/4. Storm #1 drops south through CA and favors southern tier of the Rockies. Storm #2 stays further north but might drop far enough south to hit CA’s Sierra. Storm #3 takes […]

Tomer’s Take: Two storm systems are lined-up 11/1-11/8 for the West. Storm #1 takes a deep southern track 11/1-11/4 favoring southern tier of the Rockies. Storm #2 takes a northern track 11/5-11/8 favoring northern tier of the Rockies. I like the way this pattern looks at this time. Big snow totals are possible. Current Setup […]
