Wind Chill Warnings and Advisories have been issued for most areas across the Northeast in early February 2023
New England is preparing for some of the coldest air it's seen in five years as a "dangerous" polar vortex quickly moves into the Upper Midwest and Northeast, bringing sub-zero wind chills and plunging temperatures, FOX Weather reports.
Places like Chicago and Des Moines, Iowa, will be the first to experience the bitter cold Friday morning as morning temperatures are forecast to be in the negative single digits. Other areas in the Midwest, like Northern Minnesota, could even see temps in the negative 20s or 30s.
The highs across the Midwest will struggle to make it out of the single digits Friday afternoon.
Wind chills are expected to be even worse, with feels-like temperatures dropping all the way to negative 50 in some areas. FOX Weather reports frostbite and hypothermia can form on exposed skin in as little as 10 minutes in this type of "dangerous cold."
The overnight wintry blast left a light dusting of snow across the Victorian Alps including at Mount Hotham.
Chamber of Commerce president Steve Belli said while it was an incredible sight, it was not too unusual for snow to fall in February.
"[The weather] is a little bit unpredictable these days. You never know what's going to happen ... but it's Mother Nature, you've just got to work in with it," he said.
