A widespread Arctic blast will encompass almost the entire U.S. this week, ushering in a potentially disruptive snowstorm for the South and East by the weekend.
The National Weather Service warned some of the most unusual cold is expected across the eastern U.S. (GSM pattern).
Early Wednesday and Thursday, the mercury is forecast to drop below freezing in portions of all 50 states, even in normally mild Florida and Hawaii.
Overall, temperatures will be some 6C to 16C below average for much of the week, according to the latest GFS 2-meter Temp Anomaly run (below).
By week’s end, cities such as Minneapolis and Chicago will only see high temperatures of -4C to -10C.

On top of the teeth-chattering cold, a disruptive storm system “is expected to bring a widespread wintry mess of snow, sleet and freezing rain through parts of the nation’s southern tier and possibly the East Coast late this week into next weekend,” the Weather Channel warned.
Meteorologist Ryan Maue elaborates, “a weather system will develop and gain strength from Texas into the Southeast U.S. heading into the weekend.
“This southern track means the cold air to the north will allow for frozen precipitation, including snow.”
How the storm performs and the areas worst affected is anyone’s guess at this point, meteorologists will have a better sense come Thursday — but this does have the chance to be one truly brutal wintry event.
Stay tuned for updates.
