January could be warmer than average in the Northeast and Southwest.
A mild start to the month is expected in many areas of the U.S.
The forecast grows increasingly uncertain later in the month because of several factors.
Above average temperatures could be common in the Northeast and Southwest as we head into the first month of 2021, according to the latest outlook from The Weather Company, an IBM Business.
January’s forecast shows that much above average temperatures are possible across a large portion of the Northeast. Above average temperatures are also expected in parts of the Great Lakes, mid-Atlantic and Southwest.
Most other areas of the U.S. should see temperatures that are near or close to average as well.
Since January is the coldest time of year for much of the U.S., it is important to keep in mind that an above-average forecast still means it will be cold at times.
There are several competing factors that make January’s temperature forecast uncertain.
A mild start to the month is one of the reasons January might be warmer than average in many areas. However, the door might swing open for arctic air to invade the central U.S. later in the month.
“While we expect the first 10 days of the month to be generally devoid of true arctic air, we expect the back half of the month to be much more interesting as arctic air finally loads into western Canada and dumps into parts of the central U.S.,” said Dr. Todd Crawford, chief meteorologist with The Weather Company.
