Baton Rouge, Louisiana – Temperatures will surge into the lower 90s by Thursday afternoon, delivering a summerlike stretch of heat that will quickly dry out conditions across Louisiana heading into the weekend.
According to the National Weather Service and NOAA’s Climate Prediction Center, Louisiana is in an 80 to 90 percent probability zone for above-normal temperatures from April 16 through April 20. A strong heat dome over the Gulf Coast and lower Mississippi Valley will suppress widespread rainfall and allow temperatures to climb well above seasonal averages.
In Baton Rouge and across East Baton Rouge, Ascension, and Livingston parishes, highs are expected to reach 90 to 93°F between 1 p.m. and 5 p.m., with overnight lows holding in the upper 60s to near 70°F. Along the I-10 and I-12 corridors, dry air and prolonged sunshine will accelerate vegetation drying, increasing wildfire risk in grassy and rural areas.
New Orleans and southeast Louisiana will see highs in the upper 80s to near 90°F with higher humidity, while Lafayette and Lake Charles could climb into the low 90s during peak heating. Northern areas including Shreveport and Monroe will also see highs in the upper 80s to near 91°F under mostly dry skies.
The precipitation outlook shows near-normal to slightly below-normal rainfall across much of the state early in this period. However, a more active pattern begins to develop between April 18 and April 22, bringing increasing chances for heavier rainfall, especially along and north of I-10.
Residents should avoid outdoor burning, stay hydrated, and limit strenuous 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 expands across Louisiana and the Gulf Coast. Additional advisories are likely as conditions begin to shift toward a more storm-active pattern early next week.
