KEY MESSAGES

Issued at 102 AM CDT Wed Mar 11 2026

- The first round of showers and thunderstorms will remain mostly along and north I-30 overnight.

- A more widespread round of showers and thunderstorms (some severe with large hail and damaging winds) will arrive across the Four State Region through the day on

- Near-normal conditions return through the weekend into next week.

DISCUSSION

Issued at 102 AM CDT Wed Mar 11 2026

Active weather conditions will continue with severe thunderstorms likely through the next 24-36 hours. Aloft, the main driver of convection is closed troughing across West Texas, projected to shift eastward and gradually close off as it swiftly shifts eastward across the Four State Region later today. As it does so, short-range computer model guidance suggests a trajectory of the center of circulation at or just south of the I-20 corridor, promoting higher amounts of wind shear and enhancing updraft separation. Storm modes are most likely to hold multi With a favorable environment for updraft development and separation, more severe weather threats are on the table, including but not limited to the following: large hail, damaging winds, and isolated tornadoes.

Post-frontal conditions will return temperatures back to near- normal by the end of this week (lower 70s/upper 40s) after a week of warmer temperatures. This reprieve continues into next week as a fairly uneventful frontal passage on Sunday delivers a reinforcing shot of colder air (Monday night temperatures likely near freezing north of I-30). Long-range guidance suggests that the rollercoaster ride will continue with another warming trend (temperature maximums approaching the lower 80s again) by the middle of next week. /16/

AVIATION

(06Z TAFS) Issued at 1108 PM CDT Tue Mar 10 2026

Very busy Aviation TAF period as a longwave trough will eject out into Southern Plains and Lower Miss Valley bringing with it scattered to numerous showers and thunderstorms with some of these storms likely severe. Currently watching a broken line of convection across N TX/S OK that will be moving into our northwest airspace over the next 3-4 hours or so. Have accounted for this at the TYR/TYR/GGG/SHV and ELD airports through sunrise this morning. As we transition into the late morning and afternoon hours, a new line of convection is forecast to develop across the I-20 Corridor of NE TX and rapidly expand east and northeast, encompassing the eastern half and southern half of our airspace through the late evening hours before all convection moves east of our airspace. Have accounted for this for all terminals. Prefrontal pressure gradient is very strong this morning through the afternoon outside of convection of course and post frontal pressure gradient is very strong as well with winds quickly shifting around to the north with sustained wind speeds near 15kts with gusts upwards of 30kts this evening across our entire airspace.
