Jackson, Mississippi – Mississippians should prepare for a week of sweltering heat and daily rain chances as oppressive humidity and temperatures in the 90s continue through June 19.
According to the National Weather Service in Jackson, a persistent weather pattern is funneling deep tropical moisture into the state, driving daily storm chances of 45% to 75% in cities like Jackson, Greenwood, and Hattiesburg. Meanwhile, heat index values are expected to climb above 100°F daily, peaking as high as 105°F in central and southern areas.
Cities like Vicksburg, Meridian, and Natchez are forecast to face both drenching downpours and extreme heat stress, increasing the risk of flash flooding and heat-related illness. Outdoor workers and vulnerable populations should take extra precautions: drink water frequently, avoid midday exposure, and ensure access to air conditioning.
Localized heavy rain could lead to ponding on roads and brief travel slowdowns, especially during afternoon and evening hours. Emergency officials urge residents to check in on elderly neighbors and monitor alerts for any severe thunderstorm or excessive heat warnings.
The threat remains in place through Thursday, with high rain chances and dangerous heat lingering into late next week.
