Valid 260554Z - 260730Z The severe weather threat for Severe Thunderstorm Watch 388 continues. SUMMARY...Local extension of Severe Thunderstorm Watch 388 as the threat for damaging gusts expands into more of eastern TN. DISCUSSION...An organized convective line continues to push southeastward across northern middle and eastern TN, with recent storm motion estimated at 37 kt. Strong to severe gusts have been reported within this line over the past hour, including a 51 kt gust at EKQ. The downstream air mass is characterized by ample low-level moisture, steep mid-level lapse rates, and 40 to 50 kt of 0-6 km bulk shear. Bulk shear vector is also north-northwesterly, which is orientated favorably for downstream propagation of the east-west line. This factors suggest some severe potential will continue with this line for at least the next hour or two. Current storm motion takes the ongoing line to the edge of the watch around 0630Z, and local extension may be warranted to cover the anticipated severe threat into more of eastern TN. ...Mosier.. 06/26/2023 ....Please see https://urldefense.com/v3/__http://www.spc.noaa.gov__;!!DZ3fj= g!5UVTBNOrva723tZZ5gAaRjjaF2cV2uydzdMCogRhRTrMShDyeUiBBCELUWSanMjAEOSbq9gIe= s3GGaBk20BHYOBjZd8$ for graphic product...
