An active pattern is setting up across the West for the holiday season with heavy snow for the Northwest in particular. Utah & Colorado will see frequent shots of light to moderate snow, while California and Oregon resorts will see both rain and snow with warmer air creeping in. The East will see a quiet pattern with a gradual warming trend, then colder air will arrive after the New Year.

Happy Christmas Eve! Santa is leaving the Sierra ahead of schedule. 5-10 inches fell over the Sierra Range on Tuesday. A potent storm is headed for the BC coast and will slam the PNW with several feet of snow, strong winds, and rising snow levels on Wednesday/Thursday. There are many red flags. The Rockies grab heavier snow from Friday to Sunday!

Whistler is reporting deep snow totals on Tue AM and snow will continue through the day across Southern BC. The next storm will arrive on Wed-Thu with lower snow levels and heavy snow for Whistler & the North Shore resorts, while the Interior will see moderate snow. New storms will continue to arrive on a daily basis from Friday to Monday (Dec 27-30).

Thanks for reading this summer! For the rest of this week, a cold front moving across the Central Rockies will bring showers & t-storms to WY, CO, & NM Wed-Thu while the West Coast states will see a late-season heat wave. Next week, isolated to scattered showers & t-storms develop across the West with continued mild temps. Heading into mid-month, the PNW will trend wetter and cooler.
