Areas affected...Northeast AR to Western KY/TN

Concerning...Severe potential...Tornado Watch likely

Valid 242058Z - 242200Z

Probability of Watch Issuance...80 percent

SUMMARY...Tornado threat will increase across northeast AR into
western KY/TN into the early evening hours. Tornado watch will
likely be issued soon.

DISCUSSION...Surface low continues to track east-northeast across
northern AR along a slowly advancing warm front that currently is
draped from western KY into northern AR north of BVX. 20z sounding
from LZK exhibits a very moist and adequately buoyant sounding for
robust deep convection, with very strong shear, supportive of
supercells and organized line segments. This environment is
gradually spreading northeast and supercell/tornado threat should
increase toward the confluence of the MS/OH River region over the
next several hours. Tornado watch appears warranted for this
evolution and will likely be issued soon.
