Bundle up! Arctic blast is coming

Temps could reach 10- 20 degrees below norms across USA

Here it comes, ready or not. After a warm November, the coldest weather of the season so far is forecast to roar across almost all of the United States this week, bringing freezing temperatures as far south as Florida.

This won’t be normal December cold, either, as temperatures will be about 10 to 20 degrees lower than typical for this month. Also, once the arctic blast arrives, it will stick around well into the weekend and perhaps longer.

The cold air moves into Seattle and the Northwest on Monday and then into the northern Rockies and northern Plains by Tuesday. The East Coast and Southeast can expect lower temperatures by the end of the week.

The northern tier of the USA will see several rounds of light to moderate snow, but blizzard conditions are not expected. Snow fell Sunday in the upper Midwest, giving Chicago its first accumulation of the season.

Below- zero temperatures are likely in the early mornings Tuesday through Thursday from the Rockies to the northern Plains, according to the Weather Channel.

Not surprisingly, some of the coldest weather will be in the Dakotas. Minot, N. D., should see a high of 4 degrees Wednesday, and a low of minus 3 early Thursday, the National Weather Service said.

Howling winds will create dangerous wind chills dropping as low as minus 30 Tuesday night in the northern Plains, the weather service said.

Afternoon highs in Denver, Minneapolis, Chicago, Kansas City and St. Louis will drop to the 20s by mid- week, AccuWeather said.

By Friday and Saturday, high temperatures in the East Coast and Southeast will be in the 30s and 40s.

“For many places in the East, temperatures on Friday will be lower than at any point during last year’s unusually warm December,” AccuWeather meteorologist Brian Thompson said.

“This arctic air mass will mean an early cold snap for much of Florida, where high temperatures in Tampa and Orlando will not even reach 60 degrees on Friday,” Thompson said.

A freeze is possible in Orlando by next weekend, according to WeatherBell meteorologist Ryan Maue.
