443 FXUS64 KLIX 121733AFDLIXArea Forecast DiscussionNational Weather Service New Orleans LA1233 PM CDT Fri Sep 12 2025...New SHORT TERM, LONG TERM, AVIATION, MARINE....SHORT TERM...(This afternoon through Sunday)Issued at 1233 PM CDT Fri Sep 12 2025High pressure will remain in control of the area weather throughthe weekend. This will keep things pretty quiet with above normaltemperatures and below normal rain chances. Expect lows in theupper 60s to lower 70s north and in the low to mid 70s south. With plenty of sunshine, afternoon temperatures will generally rise into the lower 90s in coastal areas and into the mid 90s for more interior areas. With dry air aloft mixing down in the afternoons, maximum heat index values should top out around 95 degrees each day. Subsidence aloft will suppress most convection, though a fewVERY isolated showers will still be possible during the late afternoon hours in response to daytime heating. Overall, rainchances will generally be 10% or lower at any given location, sono mention of precip will be carried in the forecasts. The only other thing to mention is that probabilistic tideforecasts continue to indicate potential for minor/nuisance coastal flooding as early as high tide tonight/tomorrow morning in some locations, peaking with Sunday night/Monday's high tide. This isn't our "typical" coastal flood set up as we don't really have a long period of sustained onshore flow. However, going intothe spring tide cycle, it doen't take a whole lot to push water levels up to the point of seeing minor impacts. Will hold off on any advisories for tonight as the conditions look very borderline,confidence in any impacts is low, and if impacts do occur the impacts would be very minor, only resulting in some minor pondingon some of the lowest lying roads and lots. However, if the trendcontinues, will likely need coastal flood advisory headlines for high tides beginning tomorrow night and continuing through thefirst part of next week.&&.LONG TERM...(Monday through Thursday)Issued at 1233 PM CDT Fri Sep 12 2025No significant changes to the overall forecast and thinkingthrough the long term given a pretty persistent upper patternthrough most of next week. High pressure over the central part ofthe country with troughing over the east coast will keep the localweather quiet.Generally looking at a persistence type forecast with lowscontinuing in the upper 60s to mid 70s depending on location, highs in the low to mid 90s, and no significant rain chances tospeak of.As previously mentioned above, there will be a continued threat of minor/nuisance type coastal flooding through the early part of the work week. With the spring tide cycle peaking Monday orTuesday, it currently looks as though advisories may be needed atleast in some areas for each high tide cycle through at least Tuesday night/Wednesday morning.&&.AVIATION...(18Z TAFS)Issued at 1233 PM CDT Fri Sep 12 2025VFR conditions will prevail through the period under the influenceof high pressure. Winds will generally be light (7kts or less) and outside of lake/sea breeze influences should maintain a generally northeast direction.&&.MARINE...Issued at 1233 PM CDT Fri Sep 12 2025Weak surface high pressure centered across the eastern UnitedStates will continue to result in generally easterly to northeasterly winds across the coastal waters through the weekendand into next week. Winds may become breezy at times in the 10-15kt range for Gulf waters, but will be lighter in protected waters. Waves and seas will generally be in the 1-2 ft fornearshore and protected waters with 2-4 ft in the outer waters.&&.PRELIMINARY POINT TEMPS/POPS...MCB 67 91 66 91 / 10 0 0 0 BTR 70 94 69 92 / 10 0 0 0 ASD 67 91 65 90 / 10 0 0 0 MSY 75 93 73 91 / 10 0 0 0 GPT 70 89 68 90 / 10 0 0 0 PQL 67 91 64 91 / 10 0 0 0 &&.LIX WATCHES/WARNINGS/ADVISORIES...LA...None.GM...None.MS...None.GM...None.&&$$SHORT TERM...DMLONG TERM....DMAVIATION...DMMARINE...DM
