Warm up on the way to provide relief from the bitter cold air
Temperatures are expected to rebound from 40 degrees below average to 15-20 degrees above average by late January. The warmup will be welcome for millions facing record lows this week, but it will bring a wet weather pattern across a large area of the United States.
As almost the entire country faces the invasion of cold air, the end of the cold weather is already in sight, as temperatures next week could return to 10-20 degrees above average.
According to the FOX Forecast Center, a ridge of high pressure is expected to center off the central Atlantic Ocean, allowing it to flow southward and bringing warmer weather.
The first signs of a warm-up could begin to appear in large parts of the country on Monday but intensify during the work week.
The warm air will mean that communities that typically only have high temperatures in the 20s could reach the 30s, and those that normally see the 30s could peak in the 40s to near 50 degrees.
The winter warmup will mean much of the freezing precipitation stops east of the Mississippi River, where temperatures will not be adequate to support widespread snowfall and ice threats.

“We'll have our own natural heater next week, thankfully,” said FOX Weather meteorologist Jane Minnaar. “Across the country, the entire Low 48 is expected to be above average in areas that were much lower.”
The warm-up appears similar to the weather pattern that dominated most of December, as an active subtropical jet brought a storm surge along the Gulf Coast.
Early indications are that the air mass will not reach a record high, but it will still be very noticeable and, for many, represents a big change from the blizzard conditions that swept through the regions mid-month.
For daily high temperatures to set a record in a city like Duluth, Minnesota, temperatures would have to reach around 50 degrees to enter the history books. Again, that doesn't seem likely with a lot of temperatures expected during the work week in the 30s, which is 10 to 20 degrees above average.

There is still considerable debate about how long the next warm streak will last, as some climate models expect the warm pattern to continue through the remaining winter days, while some global models show a less pronounced warm spell, with average temperatures returning with the onset of winter. February.
Forecasters at the National Oceanic and Atmospheric Administration (NOAA) noted the changing model at play in discussing recent climate forecasts.
“The building of a mid-level ridge in northwestern North America could herald a renewed outbreak of cold air over much of CONUS after the second-week period, but there is too much uncertainty due to diverging model solutions at the end of this period,” the US Climate Prediction Center said. To the National Meteorological Authority.
The coldest period of winter in the country is usually during the third week of January, but some areas of the Midwest and Great Lakes do not reach their typical coldest stage until around February.
