| Area Forecast Discussion National Weather Service New Orleans LA 656am CDT Monday Mar 16 2026 Issued at 519am CDT Monday Mar 16 2026 Had to increase Probability of Precipitation across northwest sections of the area for the next few hours, with isolated/scattered post frontal convection. Certainly won't be severe, but wouldn't be surprised to get one or two reports of graupel across southwest Mississippi as there's been video from local media in Alexandria within the last hour. The actual cold front is through our entire land area with the exception of lower Plaquemines Parish, and it will clear that area in the next hour or so. Temperatures have fallen 15-20 degrees in the last few hours with the frontal passage. Also updated CWF to eliminate the overnight Small Craft Advisory which was replaced by the Gale Warning. .SHORT TERM... (Today through Tuesday) Issued at 1224am CDT Monday Mar 16 2026 Upper trough extended from Iowa to east Texas, with ridging along the Pacific coast. A strong cold front was approaching McComb and Baton Rouge at midnight CDT. A broken line of strong to severe thunderstorms was just ahead of the front. Temperatures that were in the lower and middle 70s will drop through the 50s in the wake of the front overnight. The daytime hours today will be characterized by windy conditions, decreasing clouds and much cooler temperatures. High temperatures that were in the 80s on Sunday will not get out of the 50s today and Tuesday. Additionally, much drier air will be moving in and have lowered dew points from NBM deterministic values as they usually do not perform well in post-frontal situations. Relative humidity values combined with windy conditions justify the Red Flag Warning that was issued yesterday. For tonight, NBM continues to track well above the globals for overnight lows, and go a bit closer to NBM25 for the lows. Would note that the last cold spell, the globals ended up being too cool, so won't jump whole-heartedly onto the global numbers. Even the NBM forecast lows are near or below the records for March 17th and 18th. Won't change parameters of the Freeze Watch at this time, and assume that day shift will upgrade to a warning with the midday/afternoon package. For Tuesday, very dry air remains in place, but wind speeds will generally be below 10 mph, so don't anticipate needing Red Flag Warnings on Tuesday. Long Term (Tuesday night through Sunday) Issued at 1224am CDT Monday Mar 16 2026 Northwest upper flow continues through about Thursday before ridging builds in from the west. Surface high pressure will be over the Gulf for the 2nd half of the workweek through the weekend. Don't expect any significant precipitation through the weekend. Wednesday morning will still be chilly, and the Pearl and Pascagoula River drainage basins could hit pretty close to freezing again. Beyond that point, temperatures will moderate, returning to much above normal levels for the weekend, around 80 degrees. Marine Issued at 1224am CDT Monday Mar 16 2026 Cold front will move through most or all waters prior to sunrise. Will maintain the previously issued headlines with conditions gradually improving during the day on Tuesday. Beyond that point, don't see any wind/wave issues returning for the remainder of the forecast period. Fog doesn't appear to be much of a threat until perhaps next weekend.
