Weekend Storm Recap

A storm impacted the Central and Northern Rockies over the weekend, bringing mountain snow and colder temperatures. 

Some of the heaviest snowfall occurred on the east side of the Continental Divide in Wyoming and Southern Montana, but the Wasatch in Utah was also hit with several inches of snow.

This storm system also produced record rainfall in Salt Lake City. On Saturday, the Salt Lake City Airport had its wettest day on record with 2.47 inches of rain.

The Next Storm

Most areas will see a break in the pattern this week with beautiful fall weather. However, another storm system looms for the Rockies this weekend.

Before dropping south into the U.S., this storm will favor the Canadian Rockies, including Lake Louise, Banff Sunshine, and Marmot Basin.

Check out our forecast snowfall range for Lake Louise, with most models projecting 4-10 inches of snow this weekend.

The forecast snow level range chart also highlights the change to the weather pattern coming this weekend, with snow levels near the summit of Lake Louise at the onset of the storm on Friday, before quickly dropping below the base area this weekend.

These forecast range charts are currently available to subscribers for any location as a "free preview" and will be moved to a higher-tiered premium plan later this fall.

Forecast for Mon (Oct 6) to Tue (Oct 7):

This will be a relatively quiet start to the week with a trend toward milder and drier weather across most of the West.

However, there are a few areas where more unsettled weather will persist, including some light snow showers for the higher elevations. This includes the Northern Colorado Rockies on Monday and the Canadian Rockies on Tuesday. 

Also, snow showers are expected across Southeast Alaska, mainly above 3,000 to 4,000 feet.

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

Rain showers will impact the Southwest and the Cascades, but snow levels will be high (above ski resort summits in most areas) with a warmer airmass in place.

The higher elevations of the Canadian Rockies and BC Coast Range could see some more light snow showers.

Further north, snow will also fall over the higher terrain in Southeast Alaska, but snow levels will rise quite a bit as milder air arrives. 

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

The pattern will turn more active by the end of the week as a storm approaches. Snow levels will be high across most of the Western U.S. initially on Saturday, while a cold front will reach Canada with falling snow levels and heavier snowfall over the Canadian Rockies.  

The Southwest could also see more rain this weekend and possibly some flooding risks thanks to moisture from a tropical system in the Eastern Pacific.

Forecast for Sun (Oct 12) to Thu (Oct 16):

The end of the weekend and into early next week looks active across the West with moisture favoring the Northwest, Rockies, and Southwest. Colder air will also arrive, increasing the potential for mountain snow across the Rockies and the Cascades. 

Thanks so much for reading! Next update on Wednesday (October 8).
