Large part of the subforum under a marginal risk today.
...Ohio Valley/central Appalachians...
Widely scattered thunderstorms are possible this afternoon, offering
sporadic wind damage, with isolated severe (50+ kt) gusts and
marginally severe hail possible. A narrow corridor of favorable
return-flow moisture should advect northeastward through the warm
sector just ahead of the front, with surface dew points in the mid
50s to low 60s F. This will offset modest midlevel lapse rates to
yield a field of 500-1000 J/kg MLCAPE for a few hours this
afternoon, with surface-based effective-inflow parcels at least
briefly possible as far northeast as western NY. Low-level and
deep-tropospheric speed shear should be favorable, though the
prefrontal flow will be nearly unidirectional in vertical profile.
