Lake Charles, Louisiana – A stretch of steamy afternoons and scattered thunderstorms continues across Southeast Texas and Southwest Louisiana through Sunday, with heat indices peaking near 105°F and storms threatening flash downpours each afternoon.
According to the National Weather Service in Lake Charles, a surge of Gulf moisture is fueling daily chances for thunderstorms—mainly after 1 p.m.—through the weekend. Rain chances range from 20% to 70%, with the highest likelihood on Sunday. Storms may bring torrential rainfall, frequent lightning, and localized street flooding.
In Beaumont, Lake Charles, Lafayette, and New Iberia, heat index values will regularly top 100°F, especially between noon and 4 p.m. Most locations will see highs in the lower to mid-90s with muggy overnight lows around 75°F. Although nighttime storms are less likely, daytime heating will prime the atmosphere for convection by early afternoon.
Residents should limit outdoor activity during peak heat, stay hydrated, and avoid driving across flooded roadways. If thunder roars, go indoors—cloud-to-ground lightning will be a daily hazard.
Storm coverage dips slightly midweek but returns stronger by Saturday. More updates and advisories may follow as storm clusters organize.
