A significant winter weather event impacted the Mid-South from January 23rd through January 25th, 2026, driven by a classic southern-stream cyclone interacting with entrenched Arctic air across the region. A broad, positively tilted trough extending from the Central Plains into the Desert Southwest emerged on January 23rd.

The episode as NWS MEG wrote it up.
A significant winter weather event impacted the Mid-South from January 23rd through January 25th, 2026, driven by a classic southern-stream cyclone interacting with entrenched Arctic air across the region. A broad, positively tilted trough extending from the Central Plains into the Desert Southwest emerged on January 23rd. Downstream, strong surface high pressure was centered over the Midwest and Ohio Valley, promoting persistent cold air advection into the Lower Mississippi Valley and reinforcing a shallow subfreezing airmass.
Isentropic ascent intensified across the Mid-South beginning late January 23rd, as warm, moist air overran the shallow Arctic dome. This resulted in widespread precipitation developing from southwest to northeast across the Missouri Bootheel.
Thermal profiles across the Missouri Bootheel favored predominantly snow, however, with the development of the surface low, a shallow warm nose aloft overspread the area, causing a changeover to sleet. Poor road conditions continued for nearly two weeks after the storm, causing difficult travel and widespread school cancellations.
