Southeast Louisiana and Mississippi brace for severe storms and strong winds late Sunday into Monday
The region is under a Level 1 and Level 2 severe weather risk from Sunday night through Monday morning.
SECURE YOUR TICKETS NOW, AS THEY ARE KNOWN TO SELL OUT QUICKLY. DEREK. ALL RIGHT. WE ENJOYED A BEAUTIFUL DAY ACROSS SOUTHEAST LOUISIANA AND SOUTH MISSISSIPPI TODAY. WARM AIR FLOWING IN FROM THE GULF PRECEDED A POTENT STORM SYSTEM CURRENTLY IMPACTING VARIOUS PARTS OF THE COUNTRY. A LIVE REGIONAL VIEW SHOWS THE DEVELOPING SITUATION. A STRONG LOW-PRESSURE area, mostly to our north, is bringing significant snow and icy conditions to the Midwestern United States. At the system’s trailing edge, a cold front is now delivering impactful weather to parts of the South. A severe weather threat is expected here tonight and also across the Eastern United States. Once the system progresses, a substantial severe weather threat could develop for the Mid-Atlantic states by tomorrow. However, for us in Southeast Louisiana, the period ahead of the system has been relatively calm, featuring few clouds and very warm temperatures. These temperatures, though, are expected to drop as we move into the evening and tonight. And there you see, just after midnight, we anticipate the arrival of showers and thunderstorms. So let’s examine the timing of these showers and storms in more detail on the Futurecast. You’ll notice by 9 P.M. tonight, cloudier conditions will begin to move in, with a chance of isolated showers or thunderstorms. But the main line of thunderstorms is expected to move through just after midnight. You’ll see it impacting South Mississippi and much of Southeast Louisiana. And there you see that cold front also advancing eastward. I believe by 4:00 in the morning, our severe weather threat from this system will have passed, as the cold front will have moved through by that point. Afterward, we’ll be left with some cloud cover, and isolated showers are still possible, but none of these showers are expected to be severe by any means. However, you’ll see this lingering into tomorrow morning, potentially until noon tomorrow. We then expect drier air to begin moving across much of the area, helping to clear some of the remaining cloud cover, leaving us with partly cloudy conditions for the remainder of your day on Monday. This will continue into tomorrow night and early Tuesday as well, and I believe the rest of Tuesday is shaping up to be a pleasant day. We’re looking at abundant sunshine, and it will be significantly colder. We’ll get to those temperatures in a moment. The highest severe weather threat remains primarily focused north of us. You see a Level 3 Enhanced Risk with this system, again mainly positioned to our north. However, we here in Southeast Louisiana and all of South Mississippi are currently under a Level 2 Slight Risk of severe weather. This means isolated to scattered severe thunderstorms are expected with this system. I still think the primary threat will be damaging wind gusts. Currently, I have that as a medium threat, but there’s still a low-end threat of tornadoes and hail. Flooding is not a major concern; in fact, I don’t anticipate much of that at all because this will be a fast-moving line of thunderstorms passing through. Behind the front, our winds will shift out of the north, blowing between 25 to 30 miles an hour, with occasional gusts up to 45 miles an hour also possible before calming down as we transition into tomorrow night and early Tuesday. That’s why wind advisories are in effect for tomorrow in Southeast Louisiana, and also a Red Flag Warning for much of us, due to the combination of drier and windy conditions that will create critical fire weather conditions. So, no outdoor burning. Temperatures currently range from the upper 70s to low 80s. Lows tonight will drop into the 40s. And you see our highs tomorrow will only reach the mid to upper 50s, a trend that will continue into Tuesday. Then you see that next warm-up heading our way later next week. So, as we look ahead to the broader picture, you see overall cooler conditions at the beginning of next week. Then we start to warm up, I think more significantly by Thursday and continuing into Friday, as well as into the weekend. Weather conditions will continue to stay quiet. So our next best chance
