Yes, the winter loving, mischief-making Mr. Frost is back in business. And thanks to a lift from an arctic air mass, this time he's bringing bitter cold temperatures to the U.S. and Canada--the likes of which we haven't seen since the winter of 2010-2011.
On Tuesday, Lansdowne, Ontario, Canada started the day with a low temperature of -49°F (-45°C). Now that's some serious cold! And in case you're wondering, it's some record setting cold too--the coldest air temperature measured at any observing weather station in all of North America.
In the U.S., the Midwest and Northeast have taken the brunt of the punishment. States like Michigan, Ohio, Wisconsin, and New York aren't just battling unimaginable cold, but icy winds too. Earlier in the week, wind chill values touched the -40°F and -50°F mark in a number of cities. What's more, as the cold air blows across the Great Lakes--which just so happen to be unusually warm for this time of year--it triggers heavy lake effect snow. (Snowfall rates of several inches an hour and snow totals of several feet haven't been uncommon.)
