Given the spatially and temporally confined nature of the damaging gust threat, a WW issuance remains unlikely. DISCUSSION...An organized cluster of thunderstorms with a history of damaging gusts (and at least one measured 50+ kt gust) has developed over far northeastern OH. This cluster is slowly propagating northeast as convective outflow spreads to the southeast, overturning the ambient airmass in the process. Weak deep-layer west-southwesterly flow pivoting around the Mid-Atlantic anticyclone suggests that the ongoing cluster, should it persist, will continue moving east-northeast. As such, the northeast flank of the ongoing cluster may not gust out and undercut convection for at least a few more hours. In this time-frame, 3000+ J/kg MLCAPE will support stronger storm cores capable of producing a focused corridor locally damaging gusts. However, the damaging gusts should be contained within a small area, and convection may become outflow dominant and undercut sooner than expected. A WW issuance remains unlikely in the short-term, but convective trends will continue to be monitored for the possibility of greater upscale growth and subsequent damaging wind potential. ...Squitieri/Gleason.. 06/18/2024 ....Please see https://urldefense.com/v3/__http://www.spc.noaa.gov__;!!DZ3fj= g!6W6thoyLC6PZ5rJ4k32oLbYEb4_fquAe0bWdkvm8Kw4Vdocf7eNKxWuDj89FMTWl67f9IVGrR= MLTcmvPKn9u29PK4AQ$ for graphic product...
