Areas affected...Far Southern Indiana...Kentucky...Southern
Ohio...Far Western West Virginia

Concerning...Tornado Watch 49...

Valid 150359Z - 150600Z

The severe weather threat for Tornado Watch 49 continues.

SUMMARY...A severe threat will likely continue for a couple more
hours across the Ohio Valley. Wind damage, isolated large hail, and
perhaps a brief spinup will be possible.

DISCUSSION...The latest mosaic radar imagery shows an mesoscale
convective system over the Ohio Valley, with several embedded
supercells and multiple short line segments. Weak instability is
currently located to the south of the MCS across much of Kentucky.
In spite of this, a 65 to 80 knot mid-level jet is analyzed over
northern Indiana and northern Ohio. The MCS is currently located
near the southern edge of the mid-level jet, where 0-6 km shear is
estimated to be near 50 knots, according to the RAP. In addition, a
40 knot low-level jet is analyzed over the Ohio Valley. The strong
shear suggests that severe storms will continue to be possible over
the next few hours. Wind damage, isolated large hail, and perhaps a
brief tornado will be possible. However, the severe threat is
expected to gradually decrease over time as the airmass gradually
stabilizes.
