Mississippi – Warm, humid air clings to Jackson this morning, with clouds thickening and the air feeling more like spring than January. That warmth is fueling a developing Weather threat that intensifies through the day, setting up a volatile transition before winter returns this weekend.
According to the National Weather Service in Jackson, showers and thunderstorms increase later today, with a strong to severe storm threat developing by afternoon and evening. Highs climb into the mid-70s, unusual for January 2026, adding energy to the system. Some storms may produce damaging wind gusts, frequent lightning, and heavy rain. Localized flooding is possible where storms repeat.
Rainfall totals between one and two inches are possible by the time storms exit. Roads like I-55, I-20, and Highway 49 may see ponding, reduced visibility, and sudden slowdowns during heavier downpours. Drivers should avoid flooded lanes and allow extra travel time, especially during the evening commute.
Storms linger into Friday night before cooler air arrives. Winds shift, clouds thin, and temperatures begin a steady slide. Saturday stays mild for January standards, but the change becomes more noticeable after sunset. Wet pavement may dry briefly, then refreeze in colder pockets as overnight lows dip into the upper 30s.
Sunday brings a clearer winter feel. Sunshine returns, yet highs struggle near 50, and brisk northwest winds add bite. By early next week, mornings turn crisp, with lows dropping into the 20s. Any lingering moisture could create isolated slick spots around daybreak.
Meteorologists continue tracking storm timing closely. Conditions may change quickly as storms approach. Keep weather alerts enabled and have multiple ways to receive warnings.
