FXUS64 KLIX 271129 AAA AFDLIX Area Forecast Discussion...UPDATED National Weather Service New Orleans LA 629 AM CDT Mon Oct 27 2025 ...NEW AVIATION... .KEY MESSAGES... Updated at 1150 PM CDT Sun Oct 26 2025 - Areas of fog are expected tonight into tomorrow morning, with locally dense fog possible. Those with travel plans during the early morning hours should be prepared for sudden changes in visibility. Allow extra commuting time. - Cooler and drier conditions are expected through the work week, with a substantial cooldown coming for the second half of the week behind a reinforcing cold front. - Hazardous marine conditions is forecast to return midweek after the passage of a reinforcing cold front late Tuesday. && .SHORT TERM... (Tonight through Tuesday night) Issued at 1150 PM CDT Sun Oct 26 2025 With the cold front to our east, most of the showers and storms have exited the area. There is a very thin line of showers that is trailing on the edge of the cold front but that should lose whatever little steam it has left pretty soon. Biggest short term concern is the potential for fog overnight into tomorrow morning. With widespread 1-3+ inches of areal rainfall from earlier today, there's plenty of moisture to work with and it'll likely get stuck by the overnight inversion along with light winds. Current thinking is the fog overall it won't be widespread and dense enough to necessitate a dense fog advisory, but there is definitely potential for locally dense fog at times. Otherwise it'll generally be near normal with lows in the 60s and highs in the upper 70s/near 80. && .LONG TERM... (Wednesday through Sunday night) Issued at 1150 PM CDT Sun Oct 26 2025 Next big front forecast to move through the area will be late Tuesday night into Wednesday. This front is going to be associated with a deep closed upper level low system. While this front is stronger in terms of how much cooler air it'll bring the in the area, the potential for heavy rainfall and severe doesn't seem to be too good right now. There's an okay amount of PW (around the to slightly above the current average for this time of year) and shear but the instability is almost nonexistent (<250 J/kg). Expecting mostly showers and any storms to be progressive so while the chances of rain are decent (50-70%), the overall amounts will likely be less than an inch. In the wake of this reinforcing cold front, temperatures will take a dive to more fall like temperatures with lows in the 40s and highs in the 60s. && .AVIATION... (12Z TAFS) Issued at 628 AM CDT Mon Oct 27 2025 Visibilities this morning have been tricky with fog and low stratus developing and dissipating and redeveloping over local terminals. Went a bit more optimistic with fog low and stratus for the rest of the morning as shortly after sunrise any VIS/CIG issues will quickly resolve. VFR conditions are then expected through the day and into the evening. More VIS issues will be possible for BTR, MCB, and possibly HUM...ASD...and HDC Tuesday morning. Was a bit conservative, but winds will be lighter and residual moisture from recent heavy rains may help localized fog develop. Winds will continue to be northerly and light. (Frye) && .MARINE... Issued at 1150 PM CDT Sun Oct 26 2025 With the departure of a cold front from the area, winds should begin to relax a bit and begin to turn to offshore flow through Tuesday. Another stronger reinforcing cold front is then forecast to move through the coastal waters late Tuesday into early Wednesday. Tightening pressure gradient will bring hazardous conditions to the coastal waters mid week. Small craft advisories will be likely needed and cannot rule out the potential for gale warnings as well. Conditions should begin to improve by Friday. && .PRELIMINARY POINT TEMPS/POPS...
