Areas affected...Portions of western/southern Indiana

Concerning...Tornado Watch 10...

Valid 192326Z - 200100Z

The severe weather threat for Tornado Watch 10 continues.

SUMMARY...Tornado Watch #10 continues until 0200 UTC. A supercell
thunderstorm currently tracking across northern portions of the
watch in far western/southern Indiana is the primary focus for
severe activity in the short term, and has a history of rotation and
brief tornadoes.

DISCUSSION...The supercell thunderstorm tracking across the northern
portions of Tornado Watch #10 is the primary concern for severe
weather in the next 1-2 hours, with a history of rotation and
tornado production. While further north in the cooler air, VWP
profiles from KIND show strong curvature of the hodograph in the
lowest levels which will help support continued mesocyclone and
tornado development, with values in the 0-500m layer 120 m2/s2. Even
further south away from the frontal boundary, profiles from KLVX
still show strong support for low-topped supercell longevity.
However, some uncertainty exists in how far eastward current
convection will be maintained given only modest dewpoints in the
low-to-mid 50s F. In spite of this, the cooler temperatures aloft
and buoyancy evident in proximity sounding profiles, combined with 
the strong kinematics discussed and history of tornado production,
the expectation is that severe convection should continue eastward
into central Indiana for at least the next two hours. This supercell
will continue to be capable of all hazards, including a strong
tornado.
