Mardi Gras Weekend

5-Day Forecast

Dense Fog Advisory in effect for southeast Louisiana and southern Mississippi, including coastal waters. Visibilities may fall below one-quarter mile overnight through Tuesday morning.

Mardi Gras weekend may turn more active 🌦️⚡️ Forecast guidance is starting to trend toward a stronger system moving in late Friday night into Saturday night, which could bring periods of showers and thunderstorms to the area. With this setup, there’s also the potential for locally heavy rain and a few stronger/severe storms—but it’s still too early to nail down exact timing or specific threats. If you’ve got parade plans, this is a good time to: ✅ keep checking the forecast each day this week ✅ have a backup plan for outdoor events ✅ make sure you can receive weather alerts We’ll keep you posted as confidence increases. 🎭☔️

Warm week ahead! 🌡️☀️ High pressure will keep things very warm and mostly dry through much of the week, with afternoon highs running above normal and a few spots possibly topping 80°. A weak disturbance may bring a few showers Wednesday, but overall rain chances stay low. One more thing to watch: morning fog is likely the next few mornings 🌫️ — allow extra travel time, use low beams, and be cautious on bridges and low-lying areas. Looking ahead to this weekend (heading into Mardi Gras) 🎭⛈️ — confidence is growing that a potent system will move through, increasing the chance for showers and storms. This setup could support locally heavy rain and a few strong/severe storms, but timing and exact impacts are still uncertain this far out. ✅ Check back for forecast updates daily ✅ Have a weather plan for outdoor events ✅ Make sure alerts are enabled
