Heat continues locally with tropical forecast misinformation regionally: Southern MS/AL/LA Weather Forecast – 8/25/23

I’m not going to bury the lede here, “It will be hot.” And while, sure, there is a chance for a few storms, most of them will be modest rain producers and may even be mostly ‘dry thunderstorms’ with more lightning and thunder than actual rain.

I want to talk about the tropics for a second, too.

As I talked about in my video forecast last night ( check it out here ) the area of potential development near the Gulf shouldn’t be ignored simply because some model guidance shows it heading toward florida. And I want to point toward a very good reason why.

Below on the left is the current satellite imagery of the Gulf, Yucatan and NW Caribbean. on the right is the model guidance for what should be happening right now.

The satellite data shows no area of low pressure off the coast of Honduras. The model guidance say, resoundingly, “YES! IT’S THERE!”

And it has done this for the last handful of runs.

I feel like Mean Girls.

As you can imagine, this creates a problem. When the model guidance sees something that isn’t there at “Initialization Time” + 12 hours, it is difficult to trust what it says will be out there at “Initialization Time” + 120 hours.

Will this eventually be a thing? Sure. But for now, we are still waiting for something to happen in the lower levels. And until something happens in the lower levels, we can’t tell you what will happen down the line with any of this.

Could this be a Florida problem? Yes. Could this be a Louisiana problem? Also yes.

We just don’t know yet. And anyone showing you model guidance suggesting an outcome with any level of certainty is being disingenuous. They can’t know. And I’ve seen a lot of it. And I’ve even seen it from people who I thought would know better and paid closer attention to things.

To quote every parent, ever: “I’m not mad at those people, I’m just disappointed.”

What I do know is that we have about 48 hours of watching this thing like a hawk this weekend. Once something happens, I’ll let you guys know. Until then, maybe check those Hurricane Kits and make sure your plan is in place.

  1. May not be ANYTHING but, looking at the latest water vapor and visible radar loops, I ‘am’ seeing a flare-up in the region that is to the right of the Yucatan. Like I said, may not be anything, it is worth watching.
