Winter is officially starting this Wednesday in the United States and the cold will be arriving in full force.
Temperatures will drop this week, and even Florida won’t be spared, thanks to a strong high-pressure system moving south from Canada.
“Very cold air from the Arctic will blanket the central and eastern half of the country over a two-week period, including the busy holiday travel season,” the Climate Prediction Center said.
From Idaho to Minnesota, temperatures will be 10 to 30 degrees below average through this Sunday. By this Tuesday, that bitter cold will spread from Washington to Wisconsin and through Texas, becoming more extreme, reaching 45 degrees below normal in some areas.
“High temperatures will only reach single digits (Fahrenheit) across the northern plains, while lows will be in subzero territory and below 10 near the Canadian border,” the Weather Prediction Center said. “Strong winds will feel even colder throughout northern Montana, where wind chills are in effect with wind chills expected at minus 30 to 45 degrees.”
At that temperature, hypothermia can begin in less than 10 minutes, but in areas like South Dakota it can occur in as little as five minutes.
The National Weather Service office in Rapid City, South Dakota, said the air temperature could drop into the low 50s to 60s on Wednesday night.
To make matters worse, a wind chill advisory is in effect through Thursday. Five full days of freezing temperatures to kick off the winter season, and it’s not just for Montana.
