| Area Forecast Discussion National Weather Service New Orleans LA 231pm CDT Wednesday Mar 11 2026 .SHORT TERM... (This evening through Thursday night) Issued at 1201pm CDT Wednesday Mar 11 2026 The highlight of the short term is the frontal passage we are expecting this evening to overnight. General timing is enter the area about 5pm and depart around 5am. Prior to the front we expect scattered showers to develop and in fact they are beginning to form just to our west. Associated with the front itself will be sufficient lift and shear to support isolated severe storms with strong wind gusts and a few tornadoes up to EF-2 strength. Widespread rain amounts will be in the 1" range with isolated pockets up to 2-ish inches. This will be enough rain to make ponding of water likely and could result in roads becoming impassable. As always stay tuned for details as the weather evolves and have a way to receive watches and warnings. Long Term (Friday through Tuesday night) Issued at 1201pm CDT Wednesday Mar 11 2026 Behind theNear Term - Rest Of Today Through Tonight tal system, we expect a period of clear, but cool weather more typical of the late winter or early spring. Then, into the weekend warming brings well-above normal temperatures and humidities. By late Sunday night another upper level trough sweeps out of the plains bringing more chances of rain and stormy weather followed by a brief cool-down. Marine Issued at 1201pm CDT Wednesday Mar 11 2026 Onshore winds around 10kt prevail ahead of the frontal passage forecasted for this evening and tonight. Showers will occur ahead of the front transitioning to stronger convection as the front nears and passes with an increase in wind speed to around 15kt. Convection will be accompanied by localized strong, gusty winds and can't rule out waterspouts. When the front passes winds will shift to out of the north and increase to 20-25kt which has prompted a Small Craft Advisory. As the impacts of the passing front decrease, wind speeds drop below 10kt and turn easterly through the weekend. Another system very late in the weekend is likely to produce another round of hazardous marine conditions. NOAA New Orleans LA Office: Watches - Warnings - Advisories LA...None.
