346 FXUS64 KLIX 082319 AAA AFDLIX Area Forecast Discussion...UPDATED National Weather Service New Orleans LA 619 PM CDT Fri Aug 8 2025 ...NEW AVIATION... .SHORT TERM... (This evening through Saturday night) Issued at 1239 PM CDT Fri Aug 8 2025 We continue to be subjected to the influence of upper level high pressure to our west and east with a subtle trough (really only 3 to 4 mb lower) and a weak, nearly stalled surface front drifting north and south over the CWA and just offshore. The front is really more of a subtle difference in moisture content of the air mass. This is all adding up to some thunderstorms building in the southern CWA this afternoon. Direct impacts are gusty, variable winds in the area of any given storm. Indirectly, we may also see additional storms developing on any outflow boundaries that are generated by the existing convection. Afternoon high temps should stay in the low 90s with feels-like just over 100. Storms will die out later in the evening with the loss of daytime heating and overnight lows should be in the mid 70s. The same conditions are expected through tomorrow night. && .LONG TERM... (Sunday through Thursday night) Issued at 1239 PM CDT Fri Aug 8 2025 Conditions remain kind of stagnant into the extended period, although some slightly stronger troughing moves into the northern Gulf, providing a focus for increased PoPs ranging from 50 north to 70 south. Thus, we can expect a rainy workweek. Temperatures will remain status quo. && .AVIATION... (00Z TAFS) Issued at 617 PM CDT Fri Aug 8 2025 Convection remains low in coverage this evening. This is forecast to continue through the overnight allowing for mostly VFR conditions for the local terminals. More convection will be possible on Saturday during the daytime hours with GPT, ASD, NEW, and MSY having the best potential for brief reduced VIS/CIGs. (Frye) && .MARINE... Issued at 1239 PM CDT Fri Aug 8 2025 Winds will be in the 10-12 kt range for several days and settle to 5-10 kt for the second half of the forecast period, ranging from southerly to easterly. Seas should be no more than 2 ft. Convective activity will create variability in these values with higher winds and seas and variable wind directions in the vicinity of any thunderstorms. && .PRELIMINARY POINT TEMPS/POPS...
