Jackson, Mississippi – A prolonged stretch of hot, humid weather is expected across Mississippi between July 23 and July 27, with above-normal temperatures combining with abundant Gulf moisture to fuel daily rounds of showers and thunderstorms. The pattern favors steamy afternoons followed by scattered to numerous thunderstorms capable of producing heavy rainfall, frequent lightning and localized flooding.
According to the National Oceanic and Atmospheric Administration’s Climate Prediction Center, in its 6-10 Day Outlook issued July 17, Mississippi is favored to experience above-normal temperatures during the July 23-27 period. The state is also included in an area favoring above-normal precipitation, increasing the likelihood of more widespread rainfall than is typical for late July.
In Jackson, afternoon temperatures are expected to climb above seasonal averages while high humidity drives heat index values significantly higher. Residents should prepare for dangerous heat during the first half of the day before daytime heating triggers scattered thunderstorms during the afternoon and evening. Some storms may produce torrential downpours that quickly overwhelm storm drains, resulting in ponding on roads and reduced visibility for motorists.
Along the Gulf Coast, Gulfport is forecast to experience a similar pattern as Gulf moisture and sea breeze boundaries fuel repeated rounds of thunderstorms. While temperatures will remain above average, cloud cover and storms may briefly cool conditions later in the day. Thunderstorms could produce gusty winds, dangerous cloud-to-ground lightning and localized flooding in low-lying neighborhoods and poor drainage areas.
The hot and unsettled pattern is expected to extend across the Magnolia State, including Hattiesburg, Meridian, Tupelo, Southaven, Biloxi, Vicksburg and Natchez. Agricultural areas may benefit from periods of rainfall, but repeated heavy downpours could temporarily slow field work. Outdoor events and recreational activities may also face interruptions as thunderstorms develop during the afternoon and evening hours.
Although the Climate Prediction Center outlook does not pinpoint the exact timing or location of individual storms, confidence continues to increase that Mississippi will remain in a warmer-than-normal and wetter-than-normal pattern through July 27. Residents should stay hydrated, limit strenuous outdoor activities during the hottest part of the day, and monitor National Weather Service forecasts for updated thunderstorm and localized flood advisories.
