The UVV field related to the MCV appears
well-timed to encounter the destabilizing warm sector across
northern PA today, along and south of the frontal zone, in support
of initial development, which then should expand/intensify to severe
levels as it moves rapidly eastward toward parts of southern NY, NJ
and New England. Whether the resulting convective wind event
qualifies as a derecho may be a semantic exercise; impacts could be
of that caliber in the area affected.
