- How to protect your pet during the polar vortex
POLAR VORTEX PUTS MIDWEST - AND MAIL - ON ICE: A deadly arctic deep freeze enveloped the Midwest, forcing widespread closure of schools, offices and prompting the U.S. Postal Service to take the rare step of suspending mail delivery to a wide swath of the region because of the cold .... Many normal activities shut down and residents huddled inside as the National Weather Service (NWS) forecast plunging temperatures on Wednesday and Thursday from one of the coldest air masses in years. The bitter cold is the result of a split in the polar vortex that allowed temperatures to plunge much further south than normal.
The U.S. Postal Service said it would suspend mail delivery on Wednesday in parts or all of several Midwest states including North and South Dakota, Nebraska, Kansas, Minnesota, Wisconsin, Iowa and Illinois. The governors of Illinois, Wisconsin and Michigan all declared emergencies as the cold settled in. The NWS's forecast for Wednesday night called for temperatures in Chicago as low as minus 28, with wind chills to minus 50. The agency took to social media to stress how imperative it was to heed cold weather safety.
