Warmer temperatures have settled across the Eastern U.S. throughout the second half of January, but changes are coming as we get into February. Colder temperatures are forecast for most of the East during the month as a whole. Before this, one last intrusion of warm air associated with a ridge will move in before the first of many shots of cold air plow into the atmosphere on Thursday.
On Tuesday, the East Coast will actually be cooler than normal due to the passage of a cold front, while the Central U.S. will bake–relative to average of course–with temperatures as much as 35 degrees above average from the Dakotas through Texas. Actual temperatures will range from the 30’s, 40’s, and 50’s in the Northern Plains to the 50’s, 60’s, and even 70’s in the Central and Southern Plains. The Midwest will be around average with highs in the 20’s and the 30’s. Now to the East where temperatures will actually be as much as 20 degrees below normal. High temperatures will range from the teens, 20’s, and 30’s in the Great Lakes and Northeast, to the 30’s, 40’s, and 50’s in the Southeast. Winds will make it feel even worse with widespread wind chills Tuesday morning between 0 and 30 degrees for millions.
The heat won’t be as intense compared to average on Wednesday, but it will still be up to 30 degrees above average in the Southern Plains, while the warmer air slowly approaches the East Coast. Highs will be in the teens, 20’s, and 30’s, while the Central and Southern Plains are much milder into the 40’s, 50’s, and 60’s. The 70’s are also possible in portions of Texas and Oklahoma. To the east, temperatures will be in the 20’s, 30’s, and 40’s in the Midwest and Great Lakes. Highs will reach the teens, 20’s, and 30’s across the Northeast, which is as much as 10 degrees below average. To the south, highs will be in the 40’s and 50’s in the Mid-Atlantic. Temperatures will range from 50 to 70 degrees in the Southeast.
Now while the South and East finally all warm up on Thursday, the Northern and Central Plains will begin to experience the cool as Arctic air oozes in from Canada. Highs in this region will be up to 25 degrees above average, which corresponds to temperatures below zero, in the single-digits, or the teens. In the South where temperatures are still warmer than normal–but not for long–highs will mainly be in 50’s, 60’s, and 70’s. South Texas in the Brownsville area may even top off into the low 80’s! In the Northeast, temperatures will peak into the 30’s and 40’s while the Mid-Atlantic experiences temperatures in the 50’s and 60’s.
By Friday, most of the East, including all of the East Coast, will feel the Arctic blast. The cooler than normal temperatures will likely dominate the weather this February across the Northern Tier while the South and Central Plains experience rounds of warm and cold.
