Temperatures plunged by as much as 60 degrees Fahrenheit across the Rockies and Plains early this week, and the unrelenting cold has remained entrenched across these areas all week.
"This is exceptional cold," AccuWeather.com Senior Meteorologist Henry Margusity said. "It's the coldest air we've seen in decades during November."
Snow piled up early for residents in the Midwest and High Plains early in the week as a blast of arctic air brought chilling, blustery and icy conditions.
On Monday, Nov. 10, Minnesota State Police responded to 475 crashes statewide and over 700 vehicles that spun out of control and off roadways.
By Thursday, the northwestern United States saw wintry weather blast across the region, causing havoc for motorists from Portland, Oregon, to Boise, Idaho. The 1-84 corridor was one of the most impacted areas.
