Arctic cold front to bring winter storm, heavy snow to parts of US

Over the next few days, temperatures will be 20 to 30 degrees below average across the nation’s northern tier. More than 70% of Americans in the Lower 48 will experience temperatures below the freezing mark. Along with the cold, heavy snow will also bring a reminder that winter is not over yet.

After much of the nation enjoyed a mild weekend, frigid weather is on the way for a large chunk of the U.S. through the upcoming week, forecasters said, warning of “dangerously cold wind chills” over portions of the central U.S. 

Over the next few days, temperatures will be 20 to 30 degrees below average across the nation’s northern tier, the National Weather Service said. Several locations could see record-breaking cold. 

For example, Rapid City, South Dakota will dip from a high of 53 degrees Sunday to 1 degree for a high on Tuesday, the Weather Service said.

Across Nebraska, wind chills Tuesday will dip to as low as 40 degrees below zero, which can cause frostbite to exposed skin “in as little as 10 minutes,” the Weather Service said. “Carry a winter weather survival kit if traveling in rural areas,” the Weather Service in North Platte, Nebraska, warned.

The cold air will also invade the southern Plains. By Wednesday morning, Amarillo, Texas, will see below-zero wind chill temperatures, the Weather Service predicted. This compares to Monday’s forecast high of a balmy 72 degrees. 

CNN reported that over the next week, more than 70% of Americans in the Lower 48 will experience temperatures below the freezing mark, while more than 15 million will endure temperatures below zero.

Snow in the forecast; ‘near blizzard’ in the Dakotas 

Along with the cold, heavy snow will also bring a reminder that winter is not over yet. “A swath of plowable snow is expected from Wyoming and Colorado through northern Nebraska and the Dakotas to Minnesota, Wisconsin and northern Michigan,”  AccuWeather meteorologist Renee Duff said.

On Monday, the Weather Service warned that “increasing wind may lead to significant blowing and drifting of snow. Near-blizzard conditions are possible over parts of North and South Dakota. Travel is discouraged.

“Total snowfall amounts will likely exceed 6 inches from the Dakotas into the Upper Great Lakes. More than 12 inches are possible in some areas over the two days,” the Weather Service said.

South facing threat of severe weather, possible flooding, tornadoes 

Severe thunderstorms and potentially flooding rains are also in the forecast over the next few days across portions of the southeastern U.S. “The hazards associated with these thunderstorms are frequent lightning, severe thunderstorm wind gusts, hail and a few tornadoes,” the Weather Service said.

The Weather Service office in Nashville warned that “confidence is increasing that a multiday rainfall event will bring concerns of flooding.” 

The associated heavy rain will create numerous areas of flash flooding across the South, the Weather Service said. “Furthermore, many streams may flood, potentially affecting larger rivers from Tuesday into Wednesday morning.”
