New Orleans, Louisiana – Above-average temperatures are expected across Louisiana from August 5–9, bringing an extended stretch of summer heat while precipitation remains close to seasonal averages. Rather than a widespread wet or dry pattern, the Pelican State is expected to experience the typical isolated to scattered afternoon and evening thunderstorms common during early August, with rainfall totals varying considerably from one community to another.
According to the Climate Prediction Center’s 6–10 Day Outlook issued July 30, Louisiana is favored to experience above-normal temperatures, while near-normal precipitation is expected across the state. The outlook supports persistent warmth and high humidity with periodic thunderstorm chances but no strong signal for widespread excessive rainfall.
New Orleans and Baton Rouge are expected to see temperatures climb above early August averages, while communities including Shreveport, Lafayette, Lake Charles, Monroe, Alexandria, Houma, and Slidell should experience hot afternoons with only isolated to scattered thunderstorm development. Rainfall will likely be uneven, with some communities receiving brief downpours while nearby locations remain dry. Drivers should remain alert for changing conditions along Interstates 10, 12, 20, 49, 55, and U.S. Highway 90, where heavier showers could briefly reduce visibility and create ponding on roadways.
The combination of above-average temperatures and Gulf Coast humidity will create oppressive conditions across much of Louisiana, increasing the risk of heat-related illnesses for anyone spending extended periods outdoors. Residents should stay hydrated, limit strenuous activities during the hottest part of the afternoon, and monitor local forecasts for isolated thunderstorms that could briefly interrupt outdoor work, recreation, or travel.
The overall pattern favors continued above-average warmth through August 9, with precipitation generally remaining near climatological averages across Louisiana. Additional outlooks from the National Weather Service will provide greater detail on the timing and location of isolated thunderstorm chances as the period approaches.
