Huge Temperature Swings, Heavy Snows Announce Arctic Front’s Arrival
As the old adage goes “what a difference a day makes.” But with Monday’s weather it’s more like “what a difference an hour makes.” Numerous weather reporting sites, across the Intermountian West and the Front Range, are reporting huge temperature swings in the span of just a could of hours.
Here are some the largest temperature swings we’ve found so far:
• Cheyenne, Wyo.: 32° in two hours
• Denver, Colo.: 28° in two hours
• Fort Collins, Colo: 19° in two hours
And massive temperature swings are only part of this system’s effect on the northern tier of the country. A wide swath of the region is dealing heavy snow as well.
Winter weather advisories and winter storm warnings run from western Wyoming to the U.P. of Michigan. And up to a foot of snow is possible for places like St. Cloud, Minn., Duluth, Minn. and Sault St. Marie, Mich. The Twin Cities could see upward of eight inches of snow.
After the snow, bitter cold will stay in place for days to come. Much of the northern part of the country will see temperatures in the single digits and teens Monday night. Limited amounts of warming are also expected on Tuesday, as highs will be hard pressed to rise of the teens from Denver, northward.
A reinforcing shot of cold air will plunge temperatures even further, on Wednesday night. Denver could be dealing with near-zero lows. Marking the coldest morning in the city since February 26th. Single digits could also spill as far south as Amarillo, Texas.
When will this cold snap end? Well, long-range forecast models are indicating the eastern two-thirds of the country will be dealing with the exceptionally cold air through at least the beginning of next week. Successive shots of cold air will keep many of us in the ice box.
