   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.
