KEY MESSAGES

Issued at 1229 AM CDT Mon Sep 7 2026

- Heat Advisory has been expanded to cover the entire region for today with more widespread heat expected.

- Increased shower and thunderstorm chances for today, although they should remain isolated in nature.

- There is some indication that we could see a pattern change towards the end of the week.

DISCUSSION

Issued at 1229 AM CDT Mon Sep 7 2026

As we have mentioned or some time now, it is hot and going to remain hot. We have expanded our Heat Advisory for today and it now encompasses the entire region, every single part of it. Why is it hot? A stubborn ridge aloft is settling in, sitting right on top of us, and actively shifting its ridge axis further southwest. This ridging will continue over the next few days, which means the heat will remain in place for much of the week. To add to this heavily ridged injury, a remarkably slow-moving, lethargic frontal boundary is drifting across the mid-south and should reach our area today. This will produce some lovely compressional heating - literally squeezing the air to make it hotter, which will maximize and expand our heat threat. I did increase temperatures some across our northern zones to account for this.

Alright, how about a discussion about precipitation, moisture, or whatever you want to call it. The short and sweet of it is that we will see daily, diurnal chances for afternoon showers and thunderstorms. Underneath our giant atmospheric dome, we have some quasi-zonal flow that will continue to steer disturbances westward. Combined with weaker atmospheric subsidence we should see some convection. That being said, we will most likely not see a widespread soaking but rather a localized, hit and miss, and highly selective set-up.

There is some light at the end of the thermometer. Medium and long range guidance is suggesting a pattern change by the end of the week. Another wave of westward propagating vorticity will induce better rain chances, and the massive ridge keeping us roasting will finally break down...potentially anyways. It will be beautifully bifurcated by troughing and an attendant frontal boundary next weekend. As always, continue to monitor the forecast as this could change. Otherwise, stay safe, hydrate redundantly today, and have a wonderful and happy Labor Day! /33/

AVIATION

(12Z TAFS) Issued at 640 AM CDT Mon Sep 7 2026

For the ArkLaTex terminals, light and variable wind or calm in many locales under fair skies. Otherwise, NE-SE winds prevail at 5-10KT for another hot Summer day and some convection along and west of I-49 as the hot & dry doldrums resume. A weak boundary will allow for a light NE wind for areas east of I-49. The best chance for rainfall this afternoon will work slowly westward late day from mid afternoon along I-49, moving into E TX by early evening and largely ending with sunset. /24/
