Snow Throughout the Northwest and British Columbia

The storm train in atmospheric rivers is finally slowing down through the PNW and some areas in British Columbia. There has been a lot of precipitation associated with these ARs and colder air finally brought snow throughout the Cascades. Check out Big White Ski Resort in British Columbia with the snow piling up on Tuesday, November 7th.

The storm train will continue into British Columbia this week with some of the deepest totals thus far this season. Many areas will receive 2-3 feet with some of the highest terrain approaching 4 feet. Check out the 5-day snowfall forecast across Canada and the Northwest.

Forecast for Wed (Nov 8) to Thu (Nov 9):

The atmospheric river train will continue to bring heavy snow to Alaska and British Columbia. A few areas of light snow will swing into the PNW on Thursday evening and for some of Friday.

The Rockies will see the tail end of a weak storm system, with orographic uplift bringing moderate amounts of snow to Colorado.

A weak storm will lift through the Great Lakes and into New England. This will bring a wintry mix to many areas with light snow accumulations.

 

Forecast for Fri (Nov 10) to Sat (Nov 11):

The storm train will swing to the south in British Columbia, hammering areas with heavy snow and what might be the deepest totals of the season thus far. Some moisture will reach the Northern Rockies in the way of light snow accumulations. 

A weak disturbance moving up from Mexico will bring light snow accumulations through New Mexico.

The storm system in Eastern North America will lift to the north and bring cooler air that will develop a few lake effect snow showers around the Great Lakes and into New England. 

Forecast for Sun (Nov 12) to Mon (Nov 13):

The weather looks pretty quiet overall across the US. Moisture will swing through and clear British Columbia and the PNW adding to the growing bases to start this season.

Favorable wind directions could develop a few lake effect snow showers but cold air is hard to come by. 

Outlook for Tue (Nov 14) to Mon (Nov 18):

The forecast gets a lot more interesting in the extended outlook due to the growing model consensus of a large upper-level disturbance dipping from Alaska all the way to California. This dip, along with the strengthening of the jet stream and access to subtropical moisture, will bring precipitation to the Sierra.

There are still a lot of details that need to be figured out in ways of storm timing, strengthening, and the locations of the main precipitation bands. Either way, the hype train is all aboard and this round of atmospheric rivers is something to look forward to and watch!

Thanks so much for reading! Next update on Friday (Nov 10).
