Northern Mississippi Weather Alert: Subzero Temp Risk Returns Jan. 15–21, Snow Returns

A strong turn toward winter is predicted in northern Mississippi beginning Thursday, when Arctic air drives temperatures well below normal, raising fears about icy roads and possibly snow through Wednesday.

The National Weather Service Climate Prediction Center predicts that northern Mississippi will have a persistent spell of below-normal temperatures from January 15 to 21, when a strong Arctic pattern sets across the Mid-South. While overall precipitation is predicted to be near seasonal levels, the colder air will cause even light snow or freezing moisture to produce hazardous travel conditions.

Counties around the region, including Lee, DeSoto, Lafayette, Pontotoc, and Alcorn, are expected to have some of the coldest temperatures of the season. Overnight lows may plunge into the teens, with wind chills significantly colder in the early morning hours. Prolonged cold may stress heating systems and increase the risk of frozen pipes, especially in homes with exposed plumbing.

Travel disruptions are anticipated if snow falls during the coldest period of the trend. Even slight accumulations could provide slick conditions on Interstate 22, US 45, and Highway 78, particularly during morning rush hours. Bridges and overpasses will be especially vulnerable to icing if temperatures remain below freezing for a lengthy period.

Farther west, communities like Tunica and Clarksdale may experience somewhat warmer temperatures, but they will still face a protracted period of exceptionally chilly weather. If sunshine is scarce, rural roads and low-traffic routes may remain frozen for an extended period of time.

Residents are encouraged to prepare now by inspecting heating systems, insulating exposed pipes, and stocking vehicles with winter emergency supplies. If icy conditions develop, non-essential travel may need to be limited overnight and early in the morning.

Cold-related warnings or winter weather alerts may be issued when confidence builds. Additional updates are planned as the Arctic pattern becomes more firmly established in northern Mississippi late next week.
