Deep freeze envelops Midwest, even stops the mail
BISMARCK, N.D. — A deadly arctic deep freeze enveloped the Midwest with record-breaking temperatures Wednesday, triggering widespread closures of schools and businesses, and prompting the U.S. Postal Service to take the rare step of suspending mail delivery to a wide swath of the region.
Many normal activities shut down and residents huddled inside as the National Weather Service forecast plunging temperatures from one of the coldest air masses in years.
Officials throughout the region were focused on protecting vulnerable people from the cold , including the homeless, seniors and those living in substandard housing. Some buses were turned into mobile warming shelters to help the homeless in Chicago, where temperatures plunged to minus 19 degrees (negative 28 degrees Celsius) early Wednesday, breaking the previous record low for the day set in 1966.
