Areas affected...Ohio Valley

Concerning...Tornado Watch 198...199...

Valid 080626Z - 080830Z

The severe weather threat for Tornado Watch 198, 199 continues.

SUMMARY...A tornado, wind-damage and hail threat will likely
continue for several more hours across the Ohio Valley. Additional
weather watch issuance appears likely.

DISCUSSION...The latest mosaic radar imagery shows a multi-segmented
line of strong to severe storms located near the Ohio River from
southeast Missouri east-northeastward into southwestern
Pennsylvania. The RAP shows the strongest instability from southeast
Missouri to central Kentucky, where MLCAPE is estimated to be in the
2000 to 3500 J/kg range. Along this corridor, regional WSR-88D VWPs
and RAP forecast soundings have 0-6 km in the 45 to 55 knot range,
suggesting the supercells and bowing line segments will be possible
tonight. 0-3 km storm-relative helicities near 300 m2/s2 suggests
that an isolated tornado threat may accompany the strongest of
supercells. However, the greater threat should be for wind damage
associated with the more intense line segments. The threats are
expected to persist through much of the night, but should become
somewhat more isolated with time.
