Areas affected...southern and central Ohio...northern Kentucky...and
northern West Virginia.

Concerning...Tornado Watch 78...

Valid 022215Z - 022345Z

The severe weather threat for Tornado Watch 78 continues.

SUMMARY...A threat for all severe weather hazards will continue
through the evening.

DISCUSSION...Several supercells with a history of tornadoes are
moving into southwest Ohio. These supercells will continue to pose a
tornado threat as they move east across southern Ohio. Additional
development is ongoing ahead of this activity which may also pose a
tornado threat as storms mature. The 21Z ILN RAOB shows an uncapped,
moderately unstable atmosphere with low-level shear favorable for
tornadoes and some strong tornadoes. Expect a similar environment to
spread across much of eastern and central Ohio over the next few
hours as airmass recovery continues in the wake of earlier
convection. In addition, winds have backed across Ohio with strong
pressure falls in response to the rapidly deepening surface low near
southern Lake Michigan which will continue to support a tornado
threat. 

The greatest tornado threat is expected south of I-70 in Ohio where
dewpoints of 63 to 65F and greater instability will support a
greater tornado threat amid favorable low-level shear. 

Expansion of tornado watch 78 will be needed with an additional
tornado watch likely across much of southern, eastern, and
potentially northern Ohio.
