Active storm track through Christmas across the West

Tomer’s Take

  • I’m forecasting 3-4 different storm systems through Christmas for California’s High Sierra from Shasta to Tahoe to Mammoth.
  • Two of the storm systems next week could have atmospheric river influence.
  • I’m forecasting three different storm systems through Christmas for the Pacific Northwest.
  • A storm system could hit the Intermountain West (ID, UT, WY, MT, CO) around Christmas (12/23-12/25).

Look at the active storm track over the Pacific Ocean.

Snow is falling across California’s High Sierra Thursday morning. Here’s the view at Mammoth Mountain.

If the atmospheric river (AR) does influence California’s storm systems next week then we could be looking at significant snow. The latest integrated vapor transport forecast does indicate weak to moderate AR intensity 12/20-12/22.

IVT forecast 12/16/2021.

Wind

Wednesday delivered severe wind to Colorado. Gusts ranged from 60-112mph+. Looking ahead, my wind gust forecast is more reasonable on Colorado’s 14ers.

    This is cool. I try to watch you in the mornings. I have a roofing company and I need to know what is going on with the weather. For the longest time when it comes to the weather. My brothers and I refer to the upcoming forecast as, “Tomer says. . .” Thank you.
