| Area Forecast Discussion National Weather Service New Orleans LA 652pm CDT Tuesday May 30 2023 Long Term (Friday through Monday night) Issued at 222pm CDT Tuesday May 30 2023 The longer term will be characterized by persistent troughing present over the western Atlantic, and a general weakness across the local area. Details such as how far southwest the trough axis extends and how much moisture will remain or move into the local area continue to be a bit uncertain. Unfortunately these finer details will determine the actual sensible weather impacts across the local area. Currently it looks like the best rain chances will be late in the weekend and early next week as weak upper ridging breaks down and heigheights fall across the Gulf South allowing more diurnally forced storms to Probability of Precipitation up. However, even on the days with the best convective coverage, am still only carrying POPs generally in the 30-40% range. The latest Quantitative Precipitation Forecast guidance from WPC is similarly pessimistic on any widespread wetting rain with less than one quarter inch of rain for the majority of places over the course of the whole period. Marine Issued at 222pm CDT Tuesday May 30 2023 Predominantly calm weather pattern is forecast for the next week for the marine waters. Generally, easterly to northeasterly winds will prevail with moderate (<15 knots) wind speeds tonight through Thursday. Northeasterly to northeasterly and strong (15-20 kts) winds will dominate after the low moves through Thursday. Caution headlines may be needed for Thursday. Friday through Sunday, winds will calm back to moderate (<15 knots) and remain easterly to northeasterly. MSW NOAA New Orleans LA Office: Watches - Warnings - Advisories LA...None. GM...None.
