The eastern U.S. is forecast to see “several rounds of Arctic cold” through early February, according to meteorologists.
While the western U.S. is forecast to stay warm and dry, the National Weather Service (NWS) forecasts at least a 50 percent chance the Northeast and Great Plains will see frigid winter weather starting from Feb. 3 to 7.
The most northern reaches of Wisconsin and Minnesota, of course, have an 80 percent chance of below normal weather, which is not exactly great news given those areas are already well-below freezing.
