If the thought of frigid temperatures gives you the chills, then you may want to stay inside over the next few days because a bitter blast of cold air sweeping across the U.S. this week is threatening dozens of records.
If the frigid air wasn't enough, a fast-moving storm system known as a Manitoba Mauler brought snow to parts of the Upper Midwest and Great Lakes, including cities like Minneapolis, Chicago and Milwaukee.
Nearly 250 million Americans will feel below-average temperatures on Wednesday morning, with more than 210 million people feeling temperatures at least 10 degrees below average for Nov. 1.
Dozens of records in jeopardy
By Wednesday morning, numerous record-low temperatures are forecast to fall from Texas to Ohio, according to the FOX Forecast Center. This includes cities such as Dallas, Kansas City, St. Louis and Nashville, Tennessee.
More record lows will likely fall Thursday morning, this time across the Appalachians and mid-Atlantic, before temperatures warm a bit heading into the weekend.
A chilly Halloween
Leading the charge this week, some areas experienced the coldest Halloween on record.
Bismarck, North Dakota, had a forecast high temperature on Tuesday of a bone-chilling 25 degrees, which would break the old record of 27 degrees set on Halloween in 1919 – more than 100 years ago.
