A deep freeze is forecast to hit the U.S. Midwest this week, with snow, brutally cold temperatures and potentially life-threatening wind chill across northern IL and northwest IN by midweek, the National Weather Service said. With a polar vortex hitting the Midwest, wind chills could dip to 55 degrees below zero in northern IL.
The warning states: "A band of rain will arrive across Wales, northern and western England through the middle of Tuesday, then move eastwards through Tuesday afternoon and evening". However, most of the lower Hudson Valley will change to all rain during the day as temperatures warm to around 40 degrees.
In Indiana, a Wind Chill Watch goes into effect Tuesday night and lasts through Thursday.
Some states could suffer the coldest air in a generation, the National Weather Service said.
In its forecast discussion for the region, the Weather Service wrote that the danger of the predicted temperatures "can't be overstated", noting they will be 30 to 40°F (17 to 22°C) below normal. On Tuesday morning through Thursday morning, parts of western and central Minnesota could experience unsafe windchills as low as 65 degrees below zero.
Places as far south as Jackson, Mississippi; Birmingham, Alabama; and Chattanooga, Tennessee, may see upwards of an inch of snow. "Many accidents can be avoided by taking extra time and being respectful of other motorists", said OEMC First Deputy, Rich Guidice. A brutal blast of Arctic cold is on its way to the Midwest U.S. this week, and it will likely drop temperatures in some cities to record-setting levels. The high on Thusday in Chicago is not expected to top -14 degrees. The high temperature forecast at O'Hare on Wednesday is negative 14 degrees, which would break a record set on January 18, 1994.
Minneapolis received about four inches of snow overnight Sunday into Monday, according to WCCO, and parts of central Minnesota received as much as six inches.
Even snowplow drivers are having trouble keeping up with conditions Monday. More than 200 flights at Chicago's Midway International Airport were canceled, but only about seven flights were delayed. And once the snowstorm is over, forecasters say record cold is expected to settle into the region. In eastern North Dakota, officials have issued travel alerts because of blowing snow. Milwaukee County courts and nonessential county services will be closed Monday.
