US and Canada Daily Snow

Cold Snap Underway, Snow Favors the Great Lakes

Summary

Arctic air has overspread Southern Canada and the Lower 48, which will result in the coldest temperatures of the season so far for most areas. The Mid-Atlantic and Southern New England will wake up to fresh snow on Monday, then the pattern will largely dry out for the East with snow favoring the Great Lakes. The West will also see a dry pattern aside from a late week shot of snow for the Rockies.

Short Term Forecast

7-Day Snow Forecast:

A storm impacted the East on Sunday-Sunday night, and the Mid-Atlantic and Southern New England will wake up to some nice snow totals on Monday AM as the arctic airmass takes hold.

The 7-day snowfall projection for the Mid-Atlantic and New England will largely account for Sunday's snowfall. However, lake-effect snow showers will bring significant snowfall to Michigan, Ontario, and Western New York throughout the week, with light snow for Northern New England.

The pattern will remain quiet across the West this week, with one storm arriving late in the week. This storm will slide into the Rockies from the northwest, and similar to recent storms, areas near and east of the Divide in the Northern and Central Rockies (especially Montana) will be favored for the highest snowfall totals.

Keep an eye on ski areas such as Showdown, Big Sky, Bridger Bowl, and Red Lodge in this pattern.

Forecast for Mon (Jan 20) to Tue (Jan 21):

In the West, a weak disturbance arriving from the northwest will bring some light snow showers to areas east of the Divide in Montana and Wyoming, and to a lesser extent, Colorado and New Mexico.

The West Coast will remain under a high pressure ridge, with storms tracking along the northern periphery of the ridge bringing snow to Alaska.

In the East, a rare deep south winter storm will bring snow and ice to the Gulf Coast and the Coastal Carolinas, but will mostly miss ski resorts in the East. However, the lake effect snow machine will crank up across Michigan, Ontario, and Western New York.

Forecast for Wed (Jan 22) to Thu (Jan 23):

A storm will move into Western Canada and the Northern U.S. Rockies on Thursday with light to moderate snow developing, favoring areas east of the Divide. The Washington Cascades will also see some light snow.

In the East, the coastal storm that will bring snow to the deep south on Tuesday will track offshore as it lifts northward adjacent to the Atlantic Coast on Wednesday. Coastal areas of New England could potentially see some snow, but ski resorts will most likely miss out unless there is a significant storm track shift.

Lake effect snow showers will continue, with ski resorts in Michigan seeing some of the deepest snowfall totals by this point in the week.

Forecast for Fri (Jan 24) to Sat (Jan 25):

In the West, light to moderate snow will fall across the Central Rockies from Montana to Colorado as a storm works its way southward. Areas east of the Divide will be favored for the highest totals. To the north, storms will continue to bring significant snowfall to Alaska.

In the East, another disturbance will track across the Great Lakes with more snow expected. We may also see a bit more snow shower activity extend into Northern New England with this round compared to prior days.

Extended Forecast

Outlook for Sun (Jan 26) to Thu (Jan 30):

A ridge of high pressure will rebuild over the West Coast, resulting in a drying trend for most of the West with the dominant storm track remaining further north in Alaska.

One exception is in the Southwest, where an area of low pressure may spin up, leading to some snow potential across the Four Corners region.

The cold snap will finally start to ease across most of North America, with cold air lingering in the East but moderating compared to prior days. An active pattern is expected across the East, however, with more snow likely.

Thanks so much for reading! Next update on Wednesday (January 22).
