Concerning...Severe Thunderstorm Watch 108...

Valid 150134Z - 150300Z

The severe weather threat for Severe Thunderstorm Watch 108
continues.

SUMMARY...A threat for isolated hail and damaging wind continues,
but should gradually diminish with time later tonight.

DISCUSSION...A persistent storm cluster continues to backbuild
across far eastern OH into western PA this evening, aided by a feed
of modest low-level moisture beneath steep midlevel lapse rates (as
noted on regional 00Z soundings). Deep-layer flow/shear remains
sufficient for organized convection, and a couple of transient
supercells have been noted this evening within the broader storm
cluster. Large hail will continue to be a threat with the stronger
cells near the western edge of the storm cluster, where a somewhat
more discrete mode can be maintained. Rather strong low-level flow
within a remnant well-mixed boundary layer will also continue to
support a threat of isolated damaging gusts.=20

With time, nocturnal cooling/stabilization will result in storms
becoming increasingly elevated, with continued convection tending to
deplete remaining MUCAPE (as has already occurred farther east).
However, in the short term, some severe threat will spread
southeastward in conjunction with the primary outflow boundary.
Continued redevelopment of convection is also possible into
northeast OH, where steep midlevel lapse rates could support an
isolated hail threat into late evening.
