A huge winter storm is about to plague the U.S., even as some areas see record highs

Only a narrow band of the continental U.S. is expected to stay within historical temperature norms this week, according to the National Weather Service's "Mean Max Temp Anomaly Forecast" map. (NOAA)

If you're traveling across the U.S. this week, you might feel summer in one spot and winter in another: The National Weather Service is predicting temperatures hitting record highs and lows, while a huge winter storm "will plague a large portion of the country."

Some areas will see both extremes. After warming up to nearly 80 degrees on Thursday, the Washington, D.C., region will fall below freezing late Friday, with snow and rain likely on Saturday, the NWS says. Many places also will see strong winds.
