Areas affected...Southern OH...Eastern KY...Western WV

Concerning...Severe Thunderstorm Watch 277...

Valid 280007Z - 280130Z

The severe weather threat for Severe Thunderstorm Watch 277
continues.

SUMMARY...The severe threat continues across WW 277, but a continued
diminishing trend is expected across all but the far southern
portion of the watch.

DISCUSSION...At 00Z, strong to locally severe thunderstorms are
scattered throughout and just north of WW 277. A recent diminishing
trend has been noted across the central and northern portion of the
watch. With diurnal cooling now underway and generally weak midlevel
flow/effective shear across northeast KY, western WV, and southern
OH, a continued diminishing trend is expected, though isolated
instances of hail and damaging wind remain possible in the short
term.

Meanwhile, for the southwest portion of the watch across southeast
KY, more intense thunderstorm activity is ongoing on the northeast
fringe of a large and intense thunderstorm complex covering much of
KY and northern TN. A more substantial risk of severe hail and wind
exists in the short term across this area. Recent radar trends
suggest that a developing bow echo may clip portions of southeast
KY, which would result in a locally enhanced damaging wind threat in
the next 1-2 hours.
