The first weekend of meteorological winter will feature record breaking warmth for parts of the southern Tier today before cooler air starts to work in from the north on Sunday. High temperatures will still be 10 to 20 degrees above the normal for this time of year, primarily from the Southeast to the southern Plains.

A robust area of high pressure situated across the southern half of the U.S. and a strong jet stream pushing southward through the central U.S. will result in another day of record warmth. Across the Southern Tier, temperatures in the 60s and 70s will be found from Georgia to Texas, with low 80s for highs in the Desert Southwest and far southern Texas.

Many places notched more maximum temperature records across the southern half of the nation on Friday. A record high temperature was set at Joplin, Mo., where the high temperature reached 74 degrees, breaking the previous record of 73 degrees set in 2017 and 2012. Meanwhile, a record high temperature of 80 degrees was set at Harrison, Ark., which broke the old record of 79 degrees set in 1956. Additionally, South Carolina and Georgia witnessed record-breakers as well, with Asheville reporting 76 degrees for their high temperature, surpassing the previous record of 72 degrees set in 1970. Charlotte, N.C., rose to 78 degrees in the afternoon, breaking their previous record of 75 degrees set in 1998. In Atlanta, a record high temperature of 77 degrees was set Friday, breaking the old record of 74 degrees set in 1982.

Though highs are forecast to remain above normal on Sunday from the southern Plains to Southeast and Carolinas, the magnitude of the warmest anomalies will be less as the jet stream continues to move southward. Cooler air will be filling in due to a developing storm system across the Northern Plains, which will send a strong cold front into the midsection of the nation. This will shunt the warmth southward, where it will remain confined to the extreme southwest U.S., southern Texas and Gulf Coast early next week.
