Valid 230024Z - 230230Z The severe weather threat for Severe Thunderstorm Watch 290 continues. SUMMARY...A threat for wind damage and large hail will likely continue for a few more hours across parts of the Ark-La-Tex. DISCUSSION...Scattered strong to severe thunderstorms are ongoing from northeast Texas eastward into southwestern Arkansas and northern Louisiana. These storms are located on the northern edge of a strongly unstable airmass. Forecast soundings in the Ark-La-Tex from the RAP have MLCAPE near 3000 J/kg, with 0-6 km shear around 50 knots, and 700-500 mb lapse rates near 7.5 C/km. This should support supercell development, with a potential for large hail and wind damage. Damaging wind gusts will also be possible with the more intense line segments. This threat is expected to persist for a few more hours, but could become more isolated as instability begins to decrease across the Ark-La-Tex during the mid to late evening. ..Broyles.. 05/23/2024 ...Please see www.spc.noaa.gov for graphic product...
