DISCUSSION

Issued at 112 PM CDT Sun Aug 23 2026

Aside from a few very spotty showers in east Texas, this morning's rainfall has diminished, and the afternoon looks to remain mostly dry areawide. Short range CAMs continue to show some isolated showers and storms across our southernmost zones near the Toledo Bend Country this evening, with a few potentially becoming strong, but confidence in location of impacts is still limited at this writing. Any storms that do develop should diminish quickly after sunset.

The remainder of the night should remain dry areawide, with the next rainfall chances arriving tomorrow morning and remaining confined to our northeasternmost zones, from Hope along the I-30 corridor of Arkansas into north central Louisiana, including Monroe and Jena. These rainfall chances will continue through the day and into the evening and overnight hours. The SPC is highlighting an increased chance of strong to severe storms producing damaging wind gusts, with the highest risk largely southeast of the ArkLaTex, as these storms track down the lower Mississippi Valley.

The impacts of this anticipated rainfall and the associated cloud cover on the temperature forecast has prompted an adjustment to our heat headlines. For Union, Nevada, Howard, Columbia and Hempstead counties, the Heat Advisory will be allowed to expire this evening. Elsewhere, the Advisory has been extended through tomorrow evening for heat indices up to 109 degrees.

Beyond tomorrow night, our conditionally unstable pattern remains in play, with periodic rounds of showers and storms primarily across our north and east, but timing and coverage specifics will be driven by the position, extent and strength of the high over the desert southwest, and as such are very much in flux. As of this writing, a few storms are possible overnight Monday into Tuesday, followed by dry conditions Tuesday and returning rain north and east Wednesday into Thursday. Showers and storms across our south will be possible Friday with a warm and dry weekend to follow. This heat wave will continue through the middle of the week, with long range guidance giving us a bit of a "cool down" in the form of more highs in the 90s than in the triple digits by the end of this extended forecast period.

AVIATION

(18Z TAFS) Issued at 1241 PM CDT Sun Aug 23 2026

VFR conditions are expected to continue through much of the period with light cloud cover and southerly winds. There may be some convection development this afternoon, especially around KLFK and KTYR but confidence was too low to include in this package. Winds should be light and variable overnight until becoming southwesterly by midday, occasionally gusting up near 15 kts around western sites. Shower development looks more likely beginning around 24/12z from the northeast. This will mainly bring VCTS to KELD, KMLU, and possibly KTXK. The main hazards of any showers that develop will likely be visibility reductions and gusty winds. /57/

SPOTTER INFORMATION STATEMENT

Issued at 112 PM CDT Sun Aug 23 2026

Spotter activation may be needed this afternoon and evening for isolated strong storms that may produce locally gusty winds across portions of East Texas and North Louisiana south of I-20. /15/
