Jackson, Mississippi – Dangerous heat will grip Mississippi through next week, with heat index values expected to soar as high as 113°F in cities like Jackson, Vicksburg, and Greenville by Wednesday. Residents across the state should brace for oppressive humidity and hazardous outdoor conditions each afternoon.
According to the National Weather Service in Jackson, heat index values will approach or exceed 105°F in much of the state Friday through Thursday, with the highest risks centered on Vicksburg, Jackson, and the Delta region. Fatigue and heat exhaustion are possible with any prolonged outdoor activity, and even brief exposure can lead to heat-related illness.
Travelers on I-20, US-61, and US-49 should use extra caution as the heat intensifies. City services and schools in areas like Greenwood, Starkville, and Brookhaven may adjust outdoor schedules to keep people safe. The Mississippi Department of Health urges everyone to limit time outside, drink plenty of water, wear light clothing, and never leave people or pets in vehicles.
With temperatures this high, working outdoors should be limited to early morning or late evening hours. Use sunscreen and check on vulnerable neighbors. This is the region’s most intense heat stretch so far this summer, similar to the 2021 heat wave that set local records.
Warnings remain in effect through at least Friday, July 18. More advisories could be issued if conditions worsen—stay tuned to local updates.
