CENTERVILLE — Potentially life threatening wind chills will be rolling through the area today (Sunday). The National Weather Service's wind chill warning began at 6 a.m. Sunday and will last through noon on Tuesday. For Appanoose County, wind chill values are expected to be around 20 degrees below zero throughout the day on Sunday before making the drop all the way to 40 below zero Monday morning.
Some schools throughout Iowa began announcing delays or cancelations on Saturday. More are expected Sunday and Monday morning. Stay tuned to dailyiowegian.com/closings for updated school cancelation and delay information for school districts in Appanoose and Wayne counties.
The weather service is also forecasting a 50 percent change of scattered flurries on Monday, ending around 1 p.m. with only minimal snow accumulation. Winds ranging from 17-20 mph, with gusts near 30 mph, could cause for some blowing and drifting snow with some drecreased visibilities throughout Sunday and Monday.
It hasn't been this cold for decades — 20 years in Washington, D.C., 18 years in Milwaukee, 15 in Missouri — even in the Midwest, where bundling up is second nature. Weather Bell meteorologist Ryan Maue said, "If you're under 40 (years old), you've not seen this stuff before."
Preceded by snow in much of the Midwest, the frigid air will begin Sunday and extend into early next week, funneled as far south as the Gulf Coast. Blame it on a "polar vortex," as one meteorologist calls it, a counterclockwise-rotating pool of cold, dense air.
"It's just a large area of very cold air that comes down, forms over the North Pole or polar regions ... usually stays in Canada, but this time it's going to come all the way into the eastern United States," said National Weather Service meteorologist Phillip Schumacher in Sioux Falls, S.D.
