A potent, winterlike storm is forecast to spread from the Northwest and across the Rockies this week and deliver widespread accumulating snowfall that will be a welcome sight for snow lovers and an early-season boon to ski resorts. Snowfall totals could be measured in feet rather than inches.
Some of the heaviest snowfall accumulations are expected to reside somewhere near Wyoming's Interstate 25 and U.S. Highway 26 corridors, where 1-2 feet of snow and an AccuWeather Local StormMax™ of 30 inches are possible.
It may turn into a race to see which of Colorado's ski resorts can open for the ski season first, as accumulating snow and temperatures low enough to start up the snow machines are expected. In recent years, Arapahoe Basin, Loveland and Keystone Ski Resorts are typically some of the first to open up to the public, and that could be the case again this year.
There will be adverse weather to deal with across the West prior to the arrival of the larger storm system. Mother Nature seemingly flipped a switch in the West, as parts of the region have gone from bone-dry for an extended stretch to enduring multiple storms within a week's time.
Daily chances for rain and mountain snow will occur across the West through the middle of the week. Las Vegas observed its first measurable rainfall since Sept. 12 on Friday morning, as did Fresno, California. Fresno's dry stretch of weather extended back to the Spring, as the rainfall on Friday was the first measurable rain there since April 25.
The unsettled weather shifted into the central Rockies on Saturday, bringing along more clouds than sunshine and rainy weather for places like Salt Lake City and Grand Junction, Colorado. A lack of cold air in place kept snow levels at or above 9,000 feet, well above the tree line on most mountains, leading to a picturesque contrast between the snow-covered mountain tops and the yellow aspen trees in some spots.
With the exception of a few lingering showers across southern Colorado and northern New Mexico, conditions will settle down across the Rockies during the day on Sunday, as the region will largely be in-between storms. The quiet weather will not last long though, as the next storm to target the western United States will begin to hone in on the Pacific Northwest.
Wet weather is likely in Seattle and Portland on Sunday as the next storm rolls in; however, the main event is likely to occur across interior portions of the West early this week.
The storm is expected to dive deep into the Four Corners region between this coming Monday and Tuesday, funneling cold air across the Rocky Mountains. The low pressure system will also be able to draw in moisture all the way from the Gulf of Mexico, creating a recipe for a strong winter storm.
Snow levels will likely be the lowest of the season thus far, potentially proving troublesome for travelers along mountain pass roads early this week. Some of the trickiest travel spots on Monday will likely be across portions of Idaho, southwestern Montana and northwest Wyoming. Travel along Interstate 15 and 90 will likely face wet conditions across the lower-lying valleys and snow-covered roads in the higher locales. Travel in and around Yellowstone National Park may also prove to be difficult.
Wintry weather will likely continue in many of these places into Tuesday as the storm expands in size. By Tuesday, Utah's Wasatch Range, the Colorado Rockies and the mountainous terrain of Wyoming will all be in line to see accumulating snowfall. It is not out of the question that many ski resorts in this general area could pick up 3-6 inches of snowfall or more between Tuesday and Wednesday.
AccuWeather meteorologists currently believe the heaviest snow will fall across Wyoming from this storm. Strong wind gusts occurring at the same time as the snowfall may also produce blizzard conditions at times Tuesday night into Wednesday. Travel along U.S. Highway 26 between Casper and Riverton, Wyoming, could be extremely difficult if not impossible.
Farther south, the first wet flakes of the season are possible in Fort Collins, Boulder and possibly the western suburbs of Denver Tuesday night. No meaningful accumulations are expected east of the Colorado Front Range Tuesday and Wednesday.
The storm is expected to begin clearing out of the interior Rockies by Wednesday, with wet snowflakes forecast for only a few locales along the Front Range. Snowy conditions along or east of the Front Range are expected to reside well north of the Denver metropolitan area, likely in Wyoming.
Although the snowy conditions will largely taper off, the wintry chill will continue in the wake of the storm across the West. This may give some ski resorts an additional chance to shake the rust off the snow machines and get them cranking in preparation for their respective opening days.
The incoming storm will not be the first snowfall of the season for parts of the region. On Saturday, multiple inches of snow had accumulated in parts of California, Utah. Wyoming, Nevada, Idaho, Colorado and Montana.
"While some areas in the northern Rockies have already seen snow this season, this is the first notable snowfall of the season for part of the central Rockies," AccuWeather Forecast Manager Bryan Sausman said.
In Davis County, Utah, a 50-mile ultra trail marathon was canceled five hours into the race due to the inclement weather. A search-and-rescue team had to be sent out to assist 87 runners who were left stranded on Francis Peak, KSL News Radio reports.
Blame Global Warming... Of course.
Yep. I hate global warming. 😀😃🤗🤗
I wonder if the new fake checkers climate change policy on FB will ban this. :)
Used to ski Arapahoe Basin, Loveland, Keystone, Copper Mountain, Breckenridge, and Vail a lot. Loveland was great when it was snowing, because a large portion was above the tree line, and it was downhill to Denver so you didn’t have to worry about the chain law.
-California, Arizona and Nevada need the water--(sarc)
Look at a calendar. It is October. For those in the northern hemi, that means winter is coming.
Only some worthless TWOT living in the rotting heart of some metropolis that has never even seen the milky way wouldn’t recognize the signs of WEATHER!
Every bloody year it gets cold. If you are not used to that by now get back in your Momma’s basement where you belong and quit bothering the adults with your angst — no one but another TWOT is impressed.
A little bit of in need of relaxation therapy it appears. Just remember to harvest the tomato plants and check the washer fluid in the car.
And a tornado outbreak in Oklahoma forecast for today:

Let’s Go Brandon!
1 to 2 feet doesn’t sound like a “blockbuster” to me, barely enough for a base.
It’s the time of year it shows here. We had our fist snow on the higher peaks the end of August - just like every year
Step on two foot of power snow and you get a couple of inches
Praying for 50 more storms like this. The Rockies are bone dry.
Apparently they are blaming some magical entity called Mother Nature.
Mother Nature seemingly flipped a switch in the West...
Is AccuWeather to be credited with being trustworthy and "Scientific" if they continue to attribute the weather to "Mother Nature"?
These so-called Scientists call Christians the flat earthers. They need to reexamine their own faith.
Global warming causes snow because when the temperature gets too hot, it wraps around and becomes cold again. That’s science.
