Jackson, Mississippi – Temperatures will surge into the mid-90s by Thursday afternoon, delivering a summerlike stretch of heat that will quickly dry out conditions across Mississippi heading into the weekend.
According to the National Weather Service and NOAA’s Climate Prediction Center, Mississippi is in an 80 to 90 percent probability zone for above-normal temperatures from April 16 through April 20. A strong heat dome will dominate the Deep South, limiting rainfall and allowing temperatures to climb well above seasonal averages.
In Jackson and across Hinds, Rankin, and Madison counties, highs are expected to reach 91 to 94°F between 1 p.m. and 6 p.m., with overnight lows holding in the upper 60s. Along the I-55 and I-20 corridors, dry air and persistent sunshine will rapidly dry vegetation, increasing wildfire risk in wooded and rural areas.
North Mississippi, including Tupelo and Southaven, will see highs in the upper 80s to near 92°F. Along the Gulf Coast, including Gulfport and Biloxi, temperatures will reach the upper 80s with slightly higher humidity, though rainfall will remain limited.
The precipitation outlook shows a 33 to 50 percent chance of below-normal rainfall statewide, reinforcing dry ground conditions and increasing the likelihood of fire starts. Burn restrictions could be considered if dry conditions persist.
Residents should avoid outdoor burning, stay hydrated, and limit activity during peak afternoon heat. Drivers should monitor vehicle temperatures and avoid parking on dry grass to reduce fire risk.
The most intense heat is expected April 18 through April 20, when a “much above normal” zone strengthens across Mississippi and the Deep South. Additional advisories are likely as hot, dry conditions continue into early next week.
