| Area Forecast Discussion National Weather Service New Orleans LA 544am CDT Fri August 7 2026 .SHORT TERM... (Now through Monday) Issued at 1221am CDT Fri August 7 2026 A persistence forecast is the name of the game as we move through the weekend and into early next week. In the upper levels, the area will remain positioned on the western periphery of a broad ridge axis extending westward from Florida and the western Atlantic. A weak upper level vort lobe and some deeper tropical moisture riding up from the Gulf on Sunday and Monday will help push PWATs (Precipitable Waters) slightly above average at 2.1 to 2.2 inches. The main impact from this increase in upper level vorticity and moisture will be increased convective coverage during peak heating hours on Saturday and Sunday afternoon. Probability of Precipitation will increase from near average of 30 to 40 percent today to tomorrow to 40 to 60 percent on Sunday and Monday. Even with the increase in convective activity, daytime highs will continue to peak out in the low to mid 90s each day before convective initiation occurs. Heat index values will peak around 105 degrees each afternoon before any rains move through to briefly cool temperatures. Storm motion will be around 5 mph today and tomorrow, so a few spots could pick up a quick 2 to 3 inches of rain in an hour or two from the strongest storms that form. By Sunday and Monday, storm motion should increase to around 10 mph, and this will help to limit the overall flooding threat. However, a few spots could still pick up a quick 1 to 2 inches in an hour from the strongest storms. Some localized flooding will occur in poorly drained and low lying areas. Long Term (Monday night through Thursday) Issued at 1221am CDT Fri August 7 2026 Can't get more summer-like than next week. Southerly winds will remain through the extended keeping surface moisture available but mid level dry air will help keep PW values (Precipitable Water values) in the 50th to 75th percentile range, which means isolated to scattered afternoon convection looks to be the consistent trend for much of next week. In the absence of sh/ts, temps will climb into the 90s each day and heat index readings should also be flirting with advisory numbers next week, mainly by mid next week. Wind speeds should be just enough to keep ventilation raised but it won't be much longer before even the winds weaken to the point that it can barely be felt, which is common for August. Marine Issued at 1221am CDT Fri August 7 2026 Through the weekend and into early next week, a prevailing south- southeast flow of around 10 knots will keep seas of 1 to 2 feet in place across all of the waters. Scattered showers and thunderstorms will fire up each day in the early morning hours before moving inland by the afternoon hours. These storms will produce lightning strikes, heavy downpours, a few waterspouts, and locally higher winds and waves. Overall, a very typical pattern will be in place for early August.
