Jackson, MS – Drivers in central Mississippi should brace for sweltering conditions Sunday, with highs climbing near 94°F and heat index values pushing higher. I-55 and I-20 could see heat-related pavement stress, making road travel more dangerous for long hauls or heavy traffic delays.
According to the National Weather Service in Jackson, Sunday stays mostly sunny, but a humid air mass will keep conditions uncomfortable. Winds remain light, but the combination of high temperatures and humidity could strain those working outdoors or traveling for extended periods. Residents should limit midday activity, hydrate frequently, and check on vulnerable neighbors.
Sunday night offers little relief, with lows dipping only to 70°F under mostly clear skies. By Monday, the heat holds steady with highs near 93°F. Conditions shift Tuesday, when a slight chance of thunderstorms enters the forecast during the afternoon and evening, with rainfall probabilities rising to 20 percent.
Storms could bring brief downpours, slick roads, and lightning risks for commuters on U.S. 49 and local highways. The chance for storms lingers into late week, though temperatures moderate slightly, holding in the mid-80s through Thursday.
The key message: Sunday and Monday bring oppressive heat, while midweek introduces storm threats that may complicate travel across central Mississippi. Stay weather-aware, especially if driving in or around Jackson during peak afternoon hours.
