Areas affected...Parts of eastern WV...western/central VA...and
northern NC

Concerning...Severe potential...Watch likely=20

Valid 301706Z - 301900Z

Probability of Watch Issuance...80 percent

SUMMARY...The severe risk will increase with eastward extent through
mid/late afternoon. Damaging wind gusts and a few tornadoes will be
possible. A watch is likely for parts of the area, especially across
Virginia into North Carolina.

DISCUSSION...A mix of semi-discrete, marginal supercell structures
and line segments are advancing eastward across far southwestern WV
and far southwestern VA -- ahead of a surface low and cold front. In
the near-term, this activity is in an environment characterized by
weak buoyancy and strong/favorable low-level shear/SRH. As a result,
these storms will pose some tornado risk, though the limited
buoyancy casts uncertainty on the overall risk. Farther east,
continued diurnal heating of upper 50s/lower 60s dewpoints will
contribute to stronger buoyancy along/south of a quasi-warm front
extending from the surface low eastward to the Mid-Atlantic. While
low-level SRH may not be quite as high with eastward extent,=20 clockwise-curved hodographs and sufficient instability ahead of the
surface low will support damaging winds and a few tornadoes -- given
an expected cellular mode. A watch is likely for parts of the area,
with less confidence in the overall risk with westward extent.
