KEY MESSAGES

Issued at 1104 PM CDT Tue May 26 2026

- A line of showers and thunderstorms will impact much of East Texas through daybreak and continue east Wednesday morning.

- Slowly climbing temperatures and continued rain chances will remain the main focus for most of the forecast period.

DISCUSSION

Issued at 1104 PM CDT Tue May 26 2026

At the time of writing, a line of thunderstorms is moving through the Fort Worth CWA towards the Ark-La-Tx. Impacts to our East Texas counties is expected to begin soon after midnight tonight and continue eastward towards I-49 by daybreak tomorrow. There still is uncertainty on the intensity of the line as it enters our CWA tonight, especially with the southern half of the line that would mainly impact Deep East Texas. Hi- res models have been hinting at the line staying strong and organized until it reaches I-49, while other runs have the line weakening as it enters East Texas. One confidence booster is that there are no convective products currently issued for the line. This hopefully means that even with the better thermodynamics, the line is subsevere. This doesn't mean that these storms couldn't restrengthen, however. So make sure you have a way to receive warnings nearby tonight. Recent rainfall and high PWATs will also lead to a flash flooding risk with these showers, especially in urban environments. Motorists should take care during the Wednesday morning commute for any flooded spots.

This line will continue to move eastward post-sunrise tomorrow and be accompanied later by some more development in the afternoon. The upper-level ridging in place should keep these storms to the typical pop-ups from daytime heating, but that makes exact locations tough to pin down. Due to the uncertainty, I've pulled rain chances back regionwide tomorrow and Thursday. Any storms that do pop will have plenty of moisture to work with thanks to the southerly sfc flow. Expect temperatures to slowly climb along with the humidity going into the weekend. Current estimations have much of the region in the upper 80s by Friday, even with the continued scattered showers.

Long-range models have a blocking pattern taking hold of the CONUS early in the period and continuing into the early part of next week. If this verifies, much of the central CONUS would be under a ridge, us included. This will make broad forcing less likely, but lower-level features and daytime convection could still be enough to initiate scattered showers as we start the new work week.

AVIATION

(06Z TAFS) Issued at 1241 AM CDT Wed May 27 2026

For the 27/06Z TAF update, active weather will keep MVFR/IFR cigs in place through most of the period. This is due to the gradual development and progression of multiple rounds of -SHRA/-TSRA including the first round reaching KTYR as early as 27/08Z. Through 27/18Z, this round will proceed eastward across the airspace, reaching KMLU by 27/16Z. Isolated to scattered -TSRA will develop around the main cluster of activity before weakening to mostly VCSH by 28/03Z. /16/

SPOTTER INFORMATION STATEMENT

Issued at 1250 PM CDT Tue May 26 2026

Can't rule out the possibility of spotter activation becoming necessary late tonight during the predawn hours as a complex of strong storms moves our way from Central Texas, otherwise the severe weather threat will be isolated at best thru the day Wednesday.
