More heat and humidity, with a few afternoon storms: Southern MS/AL/LA Weather Forecast – 7/12/24

It’s going to be a bit warmer and more humid today. This morning, we saw some clouds moving in from the southwest, but they won’t stop temperatures from reaching the mid-90s in most areas. That will push the “Experienced Temperatures” (when we factor in sun intensity, wind, and humidity to let you know what your body will think it feels like walking around) to around 110F today.

With the added moisture and daytime heat, expect isolated to scattered showers and thunderstorms this afternoon, mainly along and south of I-20. The northern fringes of the area should stay dry.

While the AI-assisted weather maps keep most of the area dry, I tend to think we will see storms. This is one place I think the humans still have the computers beat. These storms may linger into the early evening before fading. Tonight’s lows will be in the mid 70s, slightly warmer than normal, but nothing too terrible.

This weekend, expect temperatures and humidity to rise as high pressure builds in. Temperatures will reach the upper 90s. A heat advisory will likely be needed, with heat index values (how hot it feels) between 105-110 degrees.

Early next week, Gulf moisture will move northward, raising humidity levels even more. Heat index values could exceed 110 degrees for some spots. This means we’ll likely need excessive heat warnings. There will be more chances for afternoon showers and thunderstorms, but it will still be very hot before any rain starts.

And I have some question about just how much Gulf moisture we will see to spark off extra storms. I tend to think we will be sitting on the periphery of the influence of the ridging. That means the push of air from teh south may be enough to make it more humid, but not enough to give us a meaningful boost to offer extra afternoon storms.

By late next week, a weather pattern shift may bring some “less hot” weather, but it is July, so “less hot” is still plenty warm.
