There seems to be an arctic blast rolling off of the arctic circle bringing extremely low temperatures, making this winter bitterly cold! The temperature changes will be coming in waves this week!
Temperatures this December are going to be below average all across the United States! Forecasters are predicting temperatures to be lower than 5 to 20 degrees! It is going to be a punishing blast of freezing cold air plunging into the northern half of the lower 48 in 5 to 7 days. Forecasters say that this will be most frigid air since 2014 or 2015. It is unlikely that the cold will be as intense as it was in January 2014. This is because the cold will be arriving later in the season than in 2014.
The bitter cold is expected to first arrive in the northern Rockies and northern plains on Sunday. It should reach Chicago on Tuesday and the northeastern United States by Wednesday and Thursday. Temperatures from Chicago to western Montana are expected to be 30 – 50 degrees colder than average.
An area from The Great Lakes through the Dakotas and into Wyoming and Montana are predicted to have low temperatures well below zero and even colder wind chills expected to be as low as minus 30 to minus 40 degrees. Although it is hard to pinpoint the exact locations of where the cold is expected to hit. There are highly technical computers used for this, but they do have their limitations.
