Jackson, Miss. – Mississippians are in for a sweltering and soggy stretch as dangerous heat combines with near-daily rain chances through at least Wednesday, June 19. Heat index values could soar above 105°F in cities like Greenwood, Vicksburg, and Jackson, while several rounds of thunderstorms could dump up to 4 inches of rain.
According to the National Weather Service in Jackson, a persistent upper-level pattern and deep tropical moisture are fueling widespread afternoon storms and elevated humidity across the region. Rain chances remain above 60% daily in Greenville, Hattiesburg, and Starkville through early next week, with peak rainfall totals topping 3 inches in some areas.
The compounded heat and humidity are raising health concerns. Jackson is forecast to reach 106°F in heat index values, while Vicksburg could feel as hot as 107°F.
