...Lower/Middle Ohio Valley to Cumberland Plateau...
Cold mid-level temperatures (low to mid -30s C at 500mb) associated
with the Midwest-centered cyclone will overspread the region through
tonight. Relatively cloud-free skies over the Lower/Middle Ohio
Valley and Cumberland Plateau will contribute to a further
steepening of low/mid-level lapse rates this afternoon. Even while
mixing/low-level drying will tend to occur, a warming boundary layer
with scant moisture/buoyancy may be sufficient for a few low-topped
thunderstorms this afternoon.
