| Area Forecast Discussion National Weather Service New Orleans LA 1027am CST Fri Feb 20 2026 .SHORT TERM... (This afternoon through Saturday) Issued at 1017am CST Fri Feb 20 2026 Tonight into Saturday morning, some patchy dense fog will be possible, looking at the models. The model probabilities of fog overnight are generally low (10-20%), and the fog looks to be greater than 1-2 SM, so a dense fog advisory was not issued. A weak frontal system pushes through the area late Saturday into Sunday. Looking at the models, the system is fairly weak overall in recent trends. Severe weather is not expected for our area, but we could see some strong storms as it moves through with gusty winds (30-40mph) and lightning, especially east of I-55. In terms of the rainfall, we are generally expecting less than an inch of rainfall for the system as it pushes through late Saturday into Sunday. MSW Long Term (Saturday night through Thursday) Issued at 1017am CST Fri Feb 20 2026 On the backside of the frontal system, cold air advection will bring cold temperatures and drier conditions into the area. Low temperatures on Monday will be in the mid to upper 30s with highs in the mid 50s. Some locations in southwest MS could be approaching freezing. Currently, low temperatures on Tuesday will be in the upper 20s and low 30s with some locations forecast to see temperatures below freezing, mainly for areas north of I-10/12. After Tuesday, we start to see a warming trend next week with near-normal temperatures returning to the area. Little to no rainfall is expected next week through at least Thursday. MSW Marine Issued at 1017am CST Fri Feb 20 2026 Moderate onshore flow of 10 to 15 knots will persist with patchy dense fog each night/morning through Saturday. A strong cold front will move through the coastal waters Saturday night into Sunday morning with high pressure building in again behind it. The combination of a tight pressure gradient and cold air advection will cause winds to strengthen and turn offshore again Saturday evening. Once hazardous conditions set in Saturday evening, Gale conditions are expected. A Gale Watch is in effect for Sunday morning through Sunday afternoon. A Small Craft Advisory is in effect from Sunday afternoon through Monday afternoon. NOAA New Orleans LA Office: Watches - Warnings - Advisories LA...None.
