MD 0172 CONCERNING TORNADO WATCH 27… FOR SOUTHERN INDIANA…SOUTHWEST OHIO…NORTHERN KENTUCKY
Mesoscale Discussion 0172
NWS Storm Prediction Center Norman OK
0201 AM CST Wed Feb 28 2024
Areas affected…Southern Indiana…Southwest Ohio…Northern
Kentucky
Concerning…Tornado Watch 27…
Valid 280801Z – 281000Z
The severe weather threat for Tornado Watch 27 continues.
SUMMARY…A tornado threat is expected to continue across WW 27 for
a few more hours. Isolated large hail and wind damage will also be
possible.
DISCUSSION…The latest high-resolution radar imagery shows a couple
strong to severe short line segments over southern Indiana. This
convection is located along a corridor of instability, where the RAP
is estimating MLCAPE in the 500 to 1000 J/kg range. Water vapor
imagery and 500 mb analysis from the RAP have a shortwave trough and
fast moving vorticity max located in southwest Indiana. This feature
will continue to enhance lift and provide support for continued
strong thunderstorm development early this morning. The latest
WSR-88D VWP from Indianapolis has 0-6 km shear near 55 knots
suggesting that supercells with large hail and wind damage will be
possible. In addition, a 60 to 70 knot jet is analyzed at 850 mb
centered over far northern Kentucky which will continue to provide
strong low-level shear sufficient for an isolated tornado threat.
Furthermore, an increase in the severe threat could occur over the
next few hours in northern Kentucky as cells increase in coverage
within and just to the south of WW 27.
