Jackson, Mississippi – Mississippi is sweltering under a rare Extreme Heat Warning, with heat index values soaring as high as 120° through 8 p.m. Thursday, creating hazardous conditions across much of the state.
According to the National Weather Service in Jackson, this prolonged heat wave stretches from southeast Arkansas and northeast Louisiana into every corner of Mississippi, impacting major cities including Jackson, Hattiesburg, Greenville, and Meridian. Emergency officials are urging residents to limit outdoor activity, stay hydrated, and seek air conditioning. Local agencies warn that roads, schools, and utility systems could be stressed as temperatures remain dangerously high for the next 24 hours.
Cities like Jackson, Vicksburg, and Brookhaven may see midday heat index readings above 115°, while Delta counties and rural areas face elevated risks for heat-related illnesses. Medical centers in Hattiesburg and Greenwood report an uptick in heat exhaustion cases. Jackson Public Schools and area summer programs are canceling outdoor events, and some power companies are bracing for possible outages due to high demand.
Residents should avoid strenuous activity between 11 a.m. and 7 p.m., check on vulnerable neighbors, and never leave children or pets in cars—even for a few minutes. Light, loose clothing and frequent water breaks are crucial.
Extreme heat conditions will persist into Thursday evening, with more advisories possible if the heat lingers.
