Another round of storms with eyes on the Gulf: Southern MS/AL/LA Weather Forecast – 7/11/22

Another day of afternoon storms across the region as a diffuse boundary continues to be the focal point for afternoon storms. Things shouldn’t be as robust as two days ago, but we will still see a handful of storms develop in the afternoon heat.

And there will be plenty of heat!

Afternoon highs will be back into the lower 90s with Heat Index values up around 105F this afternoon. Not quite as hot as the last few days, but plenty hot for anyone without AC or folks having to work outside.

The storms this afternoon will help to cool some folks down, but it doesn’t look like coverage with be overly robust, so not everyone will get some help from Mother Nature today.

Beyond the handful of afternoon storms today and tomorrow, there may be something brewing in the Gulf. Recall, back in May, I mentioned that this year was likely to be a “watch storms develop close to home” kind of year. And so far, that’s been the story.

The National Hurricane Center gives a little cluster of storms a 30-percent chance for tropical development during the next five days in the Gulf. These storms will start out over land and drift out into the Gulf. That is why the “X” above is on land and then the outlined area of potential development is over water.

You can almost think of this like those African waves. The cluster of storms drift off the African coast and have the potential to spin up into a tropical system. Same goes here. This one is “built” a bit differently, and is just much closer to home, but the general concept applies.

Model guidance shows this would be more of a rainmaker than a wind producer, but it is still rather early and will need to be monitored closely. Most folks probably remember Hurricane Barry from a few years ago doing a very similar thing.

You’ll notice below that the day-to-day forecast isn’t going to include the specifics of this tropical potential. So far, it is still too early to nail down anything on this, so I’m going to leave the forecast a bit more ‘general’ after about Day 3.
