Marine Weather and Tide Forecast for New Orleans, LA

LONG TERM
(Monday through Friday)
Issued at 1219 PM CDT Sat Jun 14 2025

With the weak troughing/break between ridges remaining in place to start the week, Monday through Wednesday will generally be repeats of the weekend, with relatively high rain chances and near to warmer than normal temperatures.

The upper pattern will flatten out by midweek, with weak ridging building in to end the week. This should result in a return to more typical summertime POPs by Thursday/Friday, which is lower than what the NBM is indicating at the present time. Have made some adjustments to trend a bit lower than the NBM POPs Thurs/Fri given the recent high bias of the NBM in the extended and the fact that with upper ridging building in, we really should see a decrease in convective coverage.

AVIATION
(18Z TAFS)
Issued at 1219 PM CDT Sat Jun 14 2025

Outside of convection, VFR conditions will generally prevail through the period. Scattered to numerous showers and storms in the area will lead to brief periods of lower cigs and vsbys this afternoon and have included TEMPO or PROB30 groups at each terminal during the time of most likely impacts. Have generally kept these mentions to MVFR conditions. While some of the heavier showers and storms could lead to IFR or even LIFR conditions, probability of these conditions occurring at any given site/time are too low to mention in the TAFs at this time and will need to be handled with short term amendments. The only other impact will be patchy fog overnight, with the most likely location of impact being MCB. A general repeat of today's weather is expected tomorrow, and future TAF packages will likely need to introduce afternoon convective impacts which are currently beyond the end of the TAF period except at MSY.
