Area Forecast Discussion National Weather Service New Orleans LA 330am CDT Thu Mar 27 2025 Long Term (Friday night through Tuesday) Issued at 330am CDT Thu Mar 27 2025 The next system will be provided by a cold front with some contribution of disturbances moving out of the Rio Grande area as well. This occurs Sunday night into Monday. Storm Prediction Center is showing this as having a slight risk over a very large amount of real estate. The extra forcing would provide the higher risk level with this system in relation to the first with all severe weather modes possible. This front will stall along the coast or near it and then pivot as the next front tugs at it. The next front could impact the area by mid next week. But we will take these one at a time to focus on. Marine Issued at 330am CDT Thu Mar 27 2025 Light east winds will begin to shift to SE and rise to 15-20kt today. A disturbance will move through the coastal waters Friday night through Saturday with strong to severe storms which will cause rapid wind shifts and speeds. Overall wind directions outside storms will remain SE to S at 15-20kt through the weekend. A cold front will move to the coast and stall by Monday morning and there is the possibility that at least some of the coastal waters develop a north wind at 10-15kt Monday.
