A strong low-pressure system forecast to form over Colorado and Kansas on Monday will pull moist air northward from the Gulf of Mexico, combining it with extremely cold air from the polar regions in Canada, AccuWeather meteorologist Thomas Geiger explained.
" A major snowstorm is in the cards from Colorado to Minnesota into midweek," he said.
The worst of the storm could hit late Tuesday into Wednesday, with snowfall rates as high as several inches per hour in some locations. Wind gusts could reach 60 mph, Geiger said.
"Blizzard conditions possible (for) portions of northeast Colorado late Monday night - Tuesday night," the weather service's Boulder officer tweeted. "Significant travel impacts, whiteouts, road closures & harsh livestock conditions will be possible."
Snow will continue to push eastward as the storm strengthens. Parts of Minnesota could see snow with an icy mix at times. Geiger warned that a 10th of an inch of ice can hazardous.
"Across much of central and southern Minnesota, a heavy glaze of ice may be more impactful than the snow," Geiger said. Some areas of North and South Dakota that see only snow could see 2 feet of it, he said.
The storm could last all week, AccuWeather Meteorologist Lauren Hyde said. Still unclear: The impact it will have on the Northeast at week's end. But heavy snow and ice could be on the way, forecasters said.
