Damaging gusts will be the main hazard with this activity. A severe thunderstorm watch may be needed soon. DISCUSSION...A cluster of strong to severe thunderstorms ongoing near the TX/LA border at midday may persist southeast through the afternoon along a surface boundary. A very moist (mid 70s to near 80 F dewpoints) boundary-layer exists across the area beneath very steep midlevel lapse rates (8 C/km) and strong vertical shear (40+ kt effective shear). While this cluster of storms is less intense compared to early in the morning, the downstream environment remains favorable for organized severe. A severe thunderstorm watch may be needed soon if current trends persist/intensify. ...Leitman/Hart.. 05/28/2024 ....Please see https://urldefense.com/v3/__http://www.spc.noaa.gov__;!!DZ3fj= g!7_q_OcrrH66U3ogsb52ja1VT3VCwAEwtDqU6IAst9B1UIsVDB_tJoxez8GV9EZJJOclZpBtef= 9a7K_6trRdYPQ7YqbQ$ for graphic product...
