DISCUSSION

Issued at 135 AM CDT Sat May 23 2026

The warm front and associated sfc low that brought us rain on Thursday has moved north of the region. However, isolated to scattered thunderstorms developed yesterday evening across East Texas and North Louisiana along a convergence zone near the I-20 corridor. Some of those storms were strong enough to prompt severe thunderstorm warnings, as well as flash flood warnings due to their slow movement. That convection has diminished, but additional isolated showers and thunderstorms continue to develop at this hour across North Louisiana from remnant outflow boundaries from the earlier convection. Short-term progs continue this through the overnight period, before a complex of storms move into our area this morning in association with a strong short- wave disturbance moving along the established southwest flow upper pattern in place. Models are bringing the complex across our East Texas zones along and north of I-20 around daybreak. But, additional convection is expected during the late morning and afternoon hours as the short-wave trough moves into the region. Locally heavy rainfall and localized flooding will be possible with these storms, especially since we have saturated soils in place from recent rainfall. A Flood Watch is already in effect for most of our East Texas and Louisiana zones south of I-20, but I wouldn't be surprised if we need to extend it northward, as those areas have received decent rainfall over the past few days.

From Sunday through all of next week, a couple of upper-level troughs will move into the Southern Plains, resulting in daily multiple rounds of showers and thunderstorms. The current Flood Watch will remain in effect through at least Monday evening, but could be extended through next week, as the elevated flood risk is likely to remain. The threat for organize severe weather will still remain low, but an isolated strong to severe thunderstorm can't be ruled out during this period. /20/

AVIATION

(06Z TAFS) Issued at 1225 AM CDT Sat May 23 2026

Sites are currently VFR, but will lower through the night as low cigs begin to return over the next several hours. Most sites should come down to IFR/LIFR conditions. Some patchy fog can't be ruled out, especially in areas where there's less cloud cover and calm winds. Showers and thunderstorms are expected to initiate as soon as 23/12z, but the scattered nature of these showers will make exact locations hard to pin down. These will continue through much of the day and into the overnight hours until the line is able to move through the region. Once this line pushes through, conditions should return to VFR quickly with light and variable winds. /57/

SPOTTER INFORMATION STATEMENT

Issued at 135 AM CDT Sat May 23 2026

Although spotter activation is not expected over the next 24 hours, moderate to heavy rainfall could lead to flash flooding. Also, an isolated strong to severe thunderstorm can't be ruled out. /20/
