Two Winter Storms Deliver Accumulating Northern U.S. Snow

A plowable snow will occur from parts of the Pacific Northwest into the Upper Midwest for the start of the weekend. A yardstick will likely be needed to measure final storm totals in the tallest terrain.
A couple fast-moving areas of low pressure will be the culprits, one which will glide along the Rocky Front Range with the other darting across Nebraska and northern Missouri this evening and overnight. Plentiful moisture and cold temperatures will lead to accumulating snow, particularly in the Washington Cascades, northern Rocky Front Range, and from the Dakotas to Iowa and potentially northern Illinois.
Winter Storm Warnings and Winter Weather Advisories are in effect for the Washington Cascades, northern Rocky Front Range to Utah’s Wasatch Range and the Colorado Rockies as well as from southeastern South Dakota to northern and central Illinois. Chicago and Peoria, Ill., Des Moines, Ames, and Mason City, Iowa, Sioux Falls, S.D., Aspen, Colo., and Glasgow, Mont.
An additional 8 to 14 inches of snow will blanket places like Stephens Pass in the Cascades throughout today, while 1 to more than 2 feet will fall in the tallest peaks of the Park and Elkhead mountains in Colorado by Sunday morning. Farther east, widespread 2 to 8 inch totals will be commonplace from southeastern South Dakota to southern Wisconsin and northern Illinois by mid-morning on Sunday.
Paired with gusty winds, especially in the Pacific Northwest and Rocky Front Range, travel will be slow and dangerous between mountain passes. Roads will be snow-packed and often have significantly reduced visibility. Interstates 29, 35, 64, 80, and 94 will also be slippery and snow-packed, making travel quite difficult. If you cannot avoid traveling, make sure to leave plenty of distance between you and the motorist in front of you to arrive safely at your destination.
Impressive snowfall totals have been measured already for parts of the Rocky Front Range. A fluffy 24.7 inches fell at 10,153 feet near Centennial, Wyo., while Darkhorse Lake, Mont., at 8,500 feet has picked up 10 inches in the last couple days. Georgetown, Mont., and near Victor, Idaho, have seen 6 and 7 inches, respectively, in the past 24 hours.
It’s never too early to have a supply kit packed in case of inclement weather. A simple kit including a weather radio, water, blankets, batteries, and non-perishable food items will go a long way in the event of a power outage.
