SIOUX FALLS, S.D. - Today is the day of the year when the Earth gets closer to the sun than it does on any other day. But that doesn't make it any warmer.
In fact, the Arctic air being pushed down into the United States is expected to bring temperatures to around record-low levels in parts of the Midwest when it arrives tomorrow.
Forecasters are calling for readings as low as 25 below zero in Fargo, North Dakota, and 31 below in International Falls, Minnesota. Sunday's NFL playoff game in Green Bay, Wisconsin, could be one of the coldest ever played.
Schools have already been closed Monday across Minnesota -- the first statewide closing in 17 years -- because of the extreme low temperatures that are on the way.
When people in the St. Louis area head back to work Monday morning, they could be dealing with a wind chill of 25 below zero. And a forecaster says that's "dangerous." Scott Truett of the National Weather Service says someone who isn't properly dressed for that kind of severe cold could die.
Even places that are accustomed to mild winters will be affected next week. Tuesday's high temperature in Atlanta is expected to be in the mid-20s.
