Tupelo, Mississippi – A sharp turn toward winter is expected across northern Mississippi beginning Thursday, as Arctic air drives temperatures well below normal and raises concerns for icy roads and possible snow through the following Wednesday.
According to the National Weather Service Climate Prediction Center, northern Mississippi is expected to experience a sustained period of below-normal temperatures during the Jan. 15–21 timeframe as a strong Arctic pattern settles across the Mid-South. While overall precipitation is expected to remain near seasonal levels, the colder air will allow even light snow or freezing moisture to create hazardous travel conditions.
Counties across the region, including Lee, DeSoto, Lafayette, Pontotoc, and Alcorn, are likely to see some of the coldest readings of the season. Overnight lows may fall into the teens, with wind chills dropping even lower during the early morning hours. Prolonged cold could stress heating systems and increase the risk of frozen pipes, particularly in homes with exposed plumbing.
Travel impacts are possible if snow develops during the coldest part of the pattern. Even minor accumulations could lead to slick conditions along Interstate 22, U.S. 45, and Highway 78, especially during morning commute hours. Bridges and overpasses will be especially vulnerable to icing as temperatures remain below freezing for extended periods.
Farther west, areas near Tunica and Clarksdale may see slightly higher temperatures but will still contend with a prolonged stretch of unusually cold weather. Rural roads and low-traffic routes could remain icy longer if sunshine is limited.
Residents are urged to prepare now by checking heating systems, insulating exposed pipes, and keeping vehicles stocked with winter emergency supplies. Limiting non-essential travel overnight and early in the morning may be necessary if icy conditions develop.
Cold-related advisories or winter weather alerts may be issued as confidence increases. Additional updates are expected as the Arctic pattern becomes more firmly established across northern Mississippi late next week.
