| Area Forecast Discussion National Weather Service New Orleans LA 1204am CDT Thu April 2 2026 .SHORT TERM... (Tonight through Friday night) Issued at 1130pm CDT Wednesday April 1 2026 Minor changes in store for today and Fri. This will be mainly due to placement of storms and rainfall, which should be mainly over the western half of the area today and again Fri. The chances will be higher today than Fri though. The weakness that has been over the area is being pushed and pulled east and west giving most of the area some needed rainfall since the beginning of this week. Believe it or not, there are some locations that have not recieved any rainfall this week so far. But this will change by the weekend. Some of these storms today could become strong or low end severe with hail and winds being the main issues expected. Long Term (Saturday night through Wednesday night) Issued at 1130pm CDT Wednesday April 1 2026 Upstream on Saturday, eyes will shift to the approaching surface cold front to our northwest and rather robust parent upper level trough. Much of the upper level support and get dynamics will be displaced to our north, but there will be enough low level convergence and low level moisture maintenance for widespread showers and storms associated with the front late Saturday and Sunday. Ahead of the front, isolated to scattered showers and a few thunderstorms will be possible during the daytime Saturday. However, lacking the upper level support, modest lapse rates and meaningful shear, think the overall severe weather threat will be fairly limited along and ahead of the front. That said, brief heavy rainfall will be possible as PWATs (Precipitable Waters) climb into the 1.6-1.8" range respectively. As mentioned with yesterday morning's package, GFS (Global Forecast System) showed the front stalling right along the coast late Sunday and into Monday leading to more stratiform isentropic showers on Monday. The ECM has come around closer to that scenario, although it is drier with the front a bit further south (yet closer than the forecast guidance shown yesterday at this time). Regardless, by late Monday and early Tuesday, an H5 trough will grab the surface feature and finally force it downstream. With a slightly cooler and drier trend by early to midweek next week setting up under a dry northwesterly flow aloft. (Frye) Marine Issued at 1130pm CDT Wednesday April 1 2026 Nearly stationary high pressure will continue a persistent southeast wind around 15 knots and seas of 2 to 4 feet over the coastal waters through the next several days. There could be brief periods of winds approaching 20 knots. A cold frontal passage late Saturday or Sunday will turn winds northerly on Sunday. Small Craft Advisories may be necessary Sunday night into Monday behind the front. NOAA New Orleans LA Office: Watches - Warnings - Advisories LA...None. GM...None. MS...None. GM...None. |
