The East has been the favored region for snow this week, as a storm brought significant snowfall from the Southern Appalachians to New England on Monday and Tuesday, and some ski resorts are poised to open up for the season this week. 

Northwest flow disturbances and below-average temperatures will favor frequent snow showers across New England and Quebec over the next several days, which will add up nicely over time. The forecast snowfall map below also includes snow that fell on Tuesday. 

Forecast for Wed (Nov 12):

In the West, a storm will impact British Columbia, but warm air will lead to high snow levels, with rain approaching the summits of even the highest ski resorts.

In the Northeast, another disturbance will move through from the northwest with snow showers favoring New York and Vermont.  

Forecast for Thu (Nov 13):

A storm will continue to impact Western Canada, with snow levels coming down just a touch on Thursday night, though heavy accumulations will still be confined to higher elevations with rain falling at low to mid elevations.

This storm will also impact the West Coast of the U.S., but warm air will lead to high snow levels across the Cascades and the Sierra. Rain is expected even across the higher elevation resorts around Tahoe and Mammoth, with heavy snow accumulations largely confined to areas near and above ski resort summits. 

In the Northeast, a cold northwest flow pattern will continue with snow showers favoring Quebec, New England, and New York. 

Forecast for Fri (Nov 14):

A storm will continue to impact the West with snow levels dropping low enough in the Northwest for snow accumulations at mid-mountain of many ski resorts, but lower terrain will still see mostly rain.

Rain and high snow level issues will also continue across the Sierra Nevada Range and Tahoe, with snow levels only dropping slightly from Thursday. 

In the Northeast, it will be more of the same with northwest flow snow showers across New England, New York, and Quebec.

Forecast for Sat (Nov 15):

Light snow and rain showers can be expected across the Northern Rockies as the previous storm departs. The next storm will reach the Northwest and Canada later on Saturday, but snow levels will rise once again as a warm front moves through.

In the East, a break in the action is expected during the day, then the next storm will arrive on Saturday night. Warmer air will be arriving with this storm, so New York and New England will likely see a changeover to rain or mixed precipitation. 

Forecast for Sun (Nov 16):

Yet another warm storm will impact the Northwest and Western Canada, but snow levels will remain on the higher side, with deep totals confined to higher elevation terrain in British Columbia. 

To the south, a cut-off low is expected to move into the Southwest with some snow possible for the Sierra (pending snow levels) as well as the Central and Southern Rockies. This pattern may favor the San Juan Range in Colorado, but this is subject to change depending on the track of the wobbly cut-off low. 

In the Northeast, a cold front will move through with rain/mixed precipitation changing back over to snow across Upstate New York, New England, and Quebec. 

Outlook for Mon (Nov 17) to Fri (Nov 21):

Next week's pattern is highly uncertain across the West as medium-range weather models are in poor agreement. At the very least, a trend toward colder temperatures is expected, which is good news since that means lower snow levels (with any storms) and better snowmaking conditions.

There are some signs that we could see a split flow storm track continue with the highest likelihood of storms over the Northwest and in the Southwest/Four Corners region. But this is subject to change moving forward.

In the East, a colder pattern will persist over New England for much of the week, with additional snow showers possible as disturbances sneak in from the northwest. 

Thanks so much for reading! Next update on Friday (November 14).
