Wider weather episode

An arctic air mass surged into southern Mississippi behind a strong cold front on January 25'26, 2026, resulting in dangerously cold temperatures and wind chills across the region. Strong cold air advection, driven by a 1040+ mb surface high building southward into Texas and Louisiana, combined with persistent north winds of 10 to 15 mph to produce hazardous conditions. By the morning of January 27th, air temperatures had fallen into the teens and 20s across southern Mississippi. When combined with strong northerly winds, wind chills dropped into the single digits across southwest Mississippi and values generally ranging from 10 to 15 degrees along the Mississippi Gulf Coast. These conditions persisted for several hours during the early morning, prompting an Extreme Cold Warning for the entire area.
