Still alot of details to figure out on this system. I really think we need to wait untill it crosses Florida, for us to start getting an accurate forecast on what to expect here in Acadiana.

What’s the difference between + and – lightning strikes on our radar maps? ⚡

When you see plus (+) and minus (–) signs on our radar images, they’re showing the type of lightning a storm is producing.

A thunderstorm is structured electrically like a battery. Positive charges on the top end and on the bottom end near the base of the cloud, it's mainly negative charges.

🔹 (–) Negative lightning is the most common. It usually comes from the lower parts of a thunderstorm cloud and is typically less powerful.

🔹 (+) Positive lightning is less common but more dangerous. It comes from the top of the storm, can travel farther, strike well away from the rain, and packs more energy—making it a bigger threat for fires and serious damage.

📍WHY IT MATTERS If you see a lot of positive strikes (+) on radar, it could signal a more intense storm with a higher risk for damaging wind, hail, or even tornadoes. As meteorologists we look for "polarity shifts" or changes in the amount of positive or negative strikes within a storm.

So next time you spot those symbols, you’ll know: a "+" might mean more than just lightning—it's a sign the storm is packing serious power. ⚠️

If you see any spaghetti models floating around yet, I definitely wouldn't put any faith in them. Yes its likely moisture will impact the Northern Gulf States, but still to early to try and narrow down the locations.

Sunday PM NHC update. Spot to watch remains at 20% chance to develop. 'X' now marked giving the idea where the low pressure center is. Details in the image. No invest yet so no spaghetti models. www.spaghettimodels.com

This will be something to watch towards the end of the week. I'm sure by now you are seeing some of the weather models on Facebook. There is still alot of uncertainty, and we may not have a good idea on what this will become untill Tuesday. The suspected low will still have to cross the Florida Pennisula, and then we will get a better idea on what it can become while in the Gulf. Right now, I would plan for higher rain chances towards the end of the week and into the weekend. As each day passes, the forecast will get better refined.
