US and Canada Daily Snow

Big storm for the Northwest & Northern/Central Rockies
Summary
A storm earlier this week brought heavy snow to the Cascades and Tetons, while another strong storm will bring more snow to a larger region across the Northwest and into the Rockies on Friday and Saturday. The storm track will retreat west off the Pacific Coast early next week, while much colder temperatures and light snow return to New England.
Short Term Forecast
Heavy Snow in the Cascades and Tetons this Week
A storm earlier this week dumped 1-2 feet of snow in the Washington Cascades (based on limited reports) and favored the Tetons as it moved inland with two-day snow totals of 26 inches at Jackson Hole and 24 inches at Grand Targhee. Check out the webcam image from Grand Targhee on the day after the storm (late Thursday afternoon), where tracks were spotted from skiers/riders who hiked for turns.
Forecast for Fri, Nov 13 – Sat, Nov 14
A multi-day storm will bring heavy snow to much of Western North America on Friday and Saturday. The Coast Range and Cascades will see some of the heaviest totals from this storm, especially on Friday, while the British Columbia Interior, Idaho, Utah, and Western Wyoming pick up heavy amounts as well. Tahoe and Colorado will also see moderate snowfall totals from this storm.
Forecast for Sun, Nov 15 – Mon, Nov 16
The storm track begins to retreat to the northwest on Sunday, while more snow falls across the Northwest and Northern Rockies. However, warm subtropical air associated with an Atmospheric River will lead to rising snow levels from south to north over this region, especially on Monday. Meanwhile, a welcome shot of colder air will arrive in the Northeast on Monday along with some light snow (heavier in Quebec).
Forecast for Tue, Nov 17
Snow will fall across the higher elevations in British Columbia on Tuesday, but snow levels are likely to remain high for much of the day with most areas seeing rain up to mid-mountain elevations (and higher for some areas). A cool and unsettled pattern will remain in place across the Northeast with additional light snow along with favorable snowmaking conditions.
Extended Forecast
Outlook for Wed, Nov 18 – Sun, Nov 22
During the early part of this period, the storm track will continue to favor the Pacific Northwest and British Columbia, and colder air with lower snow levels can also be expected. By late in the period, we may see a weak/moderate storm move across California and into the Central Rockies, but there is a lot of uncertainty at this time.
In the Northeast, a colder pattern will remain in place through most of this period with additional chances for light snow and continued favorable snowmaking conditions.
Thanks so much for reading, and check back for my next post on Monday, November 16th.
