Areas affected...portions of southern Indiana and northern Kentucky
Concerning...Tornado Watch 324...
Valid 270236Z - 270330Z
The severe weather threat for Tornado Watch 324 continues.
SUMMARY...A well-developed bow echo will approach the Louisville
metro in the next hour. Significant damaging winds (75+ mph) are
possible along with QLCS tornadoes.
DISCUSSION...The ongoing MCS over portions of the lower OH Valley
has continued to intensify this evening. The northern most segment
of the line has shown indications of a surging rear-inflow jet
across southwestern IN. Observed 70-80 kt velocities at 2-3km ARL on
the KVWX VAD lend high confidence to significant damaging wind
potential with the apex of this bow over the next 1-2 hours.
Experimental WOFS guidance also lends high confidence to strong
damaging wind potential with this feature. With an estimated forward
speed of 45-50 kt, damaging winds (some 75+ mph) will approach the
Louisville metro and southern IN within the next hour. QLCS
tornadoes are also possible given large low-level ESRH of 300-400
m2/s2.
