Valid 152233Z - 160000Z The severe weather threat for Tornado Watch 309 continues. SUMMARY...Additional storm development/intensification is likely through the remainder of the afternoon into this evening with organizing supercells. Tornadoes, large to giant hail and damaging winds remain possible. DISCUSSION...Across portions of central and North TX, strong to severe storms were observed maturing east of a dryline. Additional development/intensification into the evening appears likely owing to extreme buoyancy (5000 J/kg of MLCAPE) aided by an abnormally strong EML and mid to upper 70s F dewpoints. 60 kt of effective shear observed from area VADs will continue to support a predominately supercell mode with the primary threat of large to giant hail. While initially weak, especially with southern extent, low-level shear should intensify this evening as the low-level jet increases. This may also aid in some upscale growth of ongoing storms, and some expansion of additional storms moving south across the Red River from OK. Should this occur, a locally greater risk for damaging winds may develop, especially across the northeastern portions of WW309 toward the DFW metroplex later this evening. ...Lyons.. 06/15/2023 ....Please see https://urldefense.com/v3/__http://www.spc.noaa.gov__;!!DZ3fj= g!_ETZjWuSVs920E7nS5kXgkXmjkHszBAAlvgbyaMu_hKZYN8811iTXrMHYnrpSYnENhWMYccq6= esuHhNf5huDjwMcQE4$ for graphic product...
