- A Heat Advisory has been issued for today for portions of Texas, Arkansas and Oklahoma.

DISCUSSION

Issued at 1235 AM CDT Sat Sep 5 2026

Changes to the forecast for today: I have elected to issue a Heat Advisory for portions of northeast Texas, all of our Arkansas counties and then McCurtain county. This will be in effect from late morning through this evening. Heat index values will climb to around 106 to 108 degrees this afternoon in the advisory areas. Some might be wondering why I didn't elect to issue further to the south of this point, and the reason for that is there are some increased rain chances for areas along and south of the I-20 corridor. Decent enough chances that WPC has painted a Marginal Risk for excessive rainfall across these areas for today. While widespread flooding is not anticipated, some storms could produce heavy rain and lead to some localized flooding. Today will be the last good chance for more widespread rainfall through next week. While we will still have some low chances each day, they will mainly be in the form of sea-breeze convection and diurnally drive convection.

Otherwise, the main story for the next week will be the relentless heat expected across the region. The upper-air pattern shows no sign of major changes over the next week, which will help keep temperatures elevated, and heat index values at dangerous levels through the next week, with some indication that these warm summertime temperatures will continue through the middle of the month. Granted, anything past 3-4 days is greatly subject to change, but that is currently what the models are showing. So for those ready to get Halloween decor out, you are either going to have to do it in the heat, or wait till much later in the month when things cool off, as for me and my house, we will choose the heat option. /33/

AVIATION

(06Z TAFS) Issued at 1235 AM CDT Sat Sep 5 2026

For the ArkLaTex terminals, light south wind or calm in many locales with fair skies with mid an high clouds SCTVBKN. Tropical airmass and a weakness moving westward will trigger decent coverage today over our Parishes and pushing NW into SW AR and E TX. during the late day. Winds will be gusty and variable around downpours, but generally continue to prevail from the SE with easterlies through the column aloft. This wave of moisture will move deeper into TX on Sunday w/ diminishing coverage of convection to only Isold Monday.
