Watch issuance appears unlikely at this time. DISCUSSION...Regional radar imagery depicts a developing band of thunderstorms across the middle Tennessee River Valley as of 1710 UTC, with recent radar imagery from KHTX sampling velocities approaching 50 kts at 500 ft AGL within a portion of this band. Aided by forcing for ascent and modestly enhanced mid-level flow along the southern/southeastern periphery of a remnant mid-level MCV, expectation is for this activity to progress east-southeastward amid a hot, humid, and destabilizing air mass. While weak effective shear (generally 25 kts or less per latest mesoanalysis) is likely to limit overall organization and should temper the severity of this convection, steepening low-level lapse rates will likely foster some increase in the risk for at least isolated damaging wind gusts over the next 1-2 hours. Trends will continue to be monitored, but watch issuance appears unlikely at this time. ..Chalmers/Smith.. 07/10/2026 ...Please see www.spc.noaa.gov for graphic product...
