The daily routine of morning heat and humidity followed by afternoon showers and thunderstorms will continue through the weekend. Another run of significant heat is probable for the end of next week and the following weekend.
Steam First: highs to the mid-90s, feels-like 105 – 110 degrees through Tuesday
Storms Second: isolated to scattered activity, mainly afternoons
Big Heat Back: alert levels possible late next week, next weekend
Tonight & This Weekend: As showers diminish shortly after sunset, expect clearing skies and a muggy night with low temperatures heading into the mid 70s. For the weekend and early next week, the weather pattern will hold in a standard summer groove. A channel of moisture will be streaming into the atmosphere over the central Gulf Coast. This moisture will spark isolated to scattered afternoon showers and thunderstorms each day. Assessing the expected rain coverage across the 13 Parish, 2 County Forecast Area each day, expect 30% for Saturday, 40% on Sunday, and 50% on Monday. Daytime highs will consistently hit the low to mid 90s, with morning lows in the mid 70s.
Up Next: By Tuesday and Wednesday, a transition to fewer showers, and therefore more heat, will begin. The Climate Prediction Center has highlighted all of southeast Louisiana and southwest Mississippi for the potential of very hot and humid conditions from Friday, August 14 through Monday, August 17.
A strong high-pressure ridge over the region will cause hot temperatures, combined with humid air from the Gulf, to bring peak heat index values between 105 and 110 degrees, or higher, during this period. As is typical in exceptionally hot weather, showers and thunderstorms will become harder to find.
