Jackson, MS – Drivers in central Mississippi should prepare for sweltering conditions on Sunday, with highs near 94°F and heat index values climbing higher. Interstate corridors such as I-55 and I-20 could face heat-related pavement stress, raising risks for long-haul drivers and during periods of heavy traffic.
According to the National Weather Service in Jackson, Sunday will remain mostly sunny, but humidity will make conditions increasingly uncomfortable. Winds will stay light, yet the combination of high temperatures and moisture could strain outdoor workers and travelers on the road. Officials advise limiting midday activity, staying hydrated, and checking on vulnerable neighbors.
Sunday night brings little relief, with lows only dipping to around 70°F under mostly clear skies. Heat holds firm into Monday, with highs near 93°F. Conditions begin to shift Tuesday, when a slight chance of afternoon and evening thunderstorms enters the forecast, with rainfall chances around 20 percent.
These storms could bring brief heavy downpours, slick roads, and lightning risks for commuters along U.S. 49 and other highways. The storm chance lingers into late week, while temperatures moderate slightly, hovering in the mid-80s through Thursday.
The key message: oppressive heat dominates Sunday and Monday, followed by a midweek storm threat that could complicate travel across central Mississippi. Drivers should remain weather-aware, particularly during peak afternoon hours.
