Concerning...Tornado Watch 363...

Valid 160212Z - 160315Z

The severe weather threat for Tornado Watch 363 continues.

SUMMARY...Storms intermittently possessing supercell structure may
continue to yield a risk for isolated damaging gusts and perhaps a
tornado east of the tornado watch.  A watch extension-in-area may be
needed but dependent on convective trends.

DISCUSSION...Surface observations along the I-75 corridor from
Dayton to Cincinnati show temperatures near 70 degrees F with
dewpoints in the 66-68 F range.  KILN VAD shows an enlarged
low-level hodograph with 0-1km SRH around 350 m^2/s^2 when
accounting for observed storm motion.  A tornadic debris signature
was evident from KILN around 0150z in Wayne County, IN.  

Given the moist/marginally unstable airmass (250 J/kg MLCAPE per the
00z Wilmington, OH raob), a continuation of the severe storm risk
may extend beyond the current eastern edge of tornado watch 363 and
a local extension-in-area can be utilized if convective trends
warrant.
