Several storms have moved across the West recently with nice totals adding up from British Columbia to New Mexico. The Central and Southern Rockies in particular have done well in this pattern while an early week storm brought heavy snow to Tahoe as well. Check out the 5-day snow reports (updated each morning) across the West for the period ending Tuesday morning, December 15th.

A Nor'easter will impact the East on Wednesday and Thursday with heavy snow developing across the mountains of West Virginia, Virginia, and Maryland on Wednesday before spreading north into Pennsylvania, New York, and Southern New England on Wednesday night and Thursday.
The West will see another storm during this period as well. Snow will favor Coastal British Columbia on Wednesday initially, then will become more widespread across the Northern Rockies, Cascades, and Sierras on Thursday.

Extended Forecast
Outlook for Tue, Dec 22 – Sat, Dec 26
Additional snow will be possible across the Northern Rockies on the 22nd, then the pattern will take a break in the West as a ridge of high pressure builds and the storm track shifts way up north into Northern BC and Alaska. Meanwhile, a more active pattern will develop across the East late in this period with the potential for ski areas in the Mid-Atlantic and Northeast to pick up some new snow around Christmas.
