586 FXUS64 KLIX 230923 AFDLIX Area Forecast Discussion National Weather Service New Orleans LA 323 AM CST Sun Feb 23 2025 ...New SHORT TERM, LONG TERM, AVIATION, MARINE... .SHORT TERM... (Today through Monday) Issued at 314 AM CST Sun Feb 23 2025 The sfc low over the NW gulf will move along the coast today with plenty of showers moving through well in advance of the low. The threat of lightning is still valid but also still low around 20% around and south of Lake Pontchartrain building to 30% at the coast. The best timing of these probs will be from around noon through 6p today. Bascially, south shore areas will have the highest probability out of the entire CWA and isolated lightning is not out of the question. A steady light to moderate rain will move through the whole day today. The heaviest activity should end around or just after 10p tonight. But there will be some lingering light rain/mist/fog hanging around into Monday morning. Even this should get pushed out by late Monday morning. Most areas should see rainfall tallies of 1 to 2 inches and higher toward the coast. No severe wx with this one, but it will be on the cool side with temps not moving much through the day today. As this moves out Monday, conditions should improve but this will set the area up for the possibility of dense fog Monday night/Tue morning. && .LONG TERM... (Monday night through Saturday) Issued at 314 AM CST Sun Feb 23 2025 A warming trend will be in full swing Monday finally reaching the mid 70s by Wed. Another cold front may move through Thu with some cloudy skies and at best maybe a sprinkle or two but mainly cooling us back into the 60s for highs. No real arctic blast with this one. Fri through the weekend look to fairly typical late winter conditions for this area which is quite nice with highs in the 70s and lows in the 40s and 50s. No rain expected over the weekend either. && .AVIATION... (12Z TAFS) Issued at 314 AM CST Sun Feb 23 2025 Cigs will start off in MVFR for most sites but will slowly fall into IFR levels starting around sunrise today. All terminals should be in IFR by late morning or noon. Prevailing conditions will remain SHRA BR with a low probability of IFR vis with the heaviest showers. The highest probs for lightning will be BTR, MSY, NEW but only isolated and will not be enough of a probability to show in any taf set. && .MARINE... Issued at 314 AM CST Sun Feb 23 2025 Winds will remain out of the E today as a sfc low moves through the northern gulf. As the low moves through the outer coastal waters, winds will shift all around the compass late today into tonight. The low will move SE tonight bringing the sh/ts with it away from the northern gulf by Mon. Winds will remain 20 to 25kt with gusts to 30kt. There will be some gusts greater than gale force but this will mainly be associated with numerous storms. NE winds around 20kt will move in as the low moves SE tonight and remain through much of Monday before easing late Monday and Tuesday. High pressure will move into the area causing winds to become light and variable late Tue into Wed. && .PRELIMINARY POINT TEMPS/POPS...
