Areas affected...portions of southern IN and western/Northern
Kentucky

Concerning...Tornado Watch 126...127...129...

Valid 052005Z - 052130Z

The severe weather threat for Tornado Watch 126, 127, 129 continues.

SUMMARY...Damaging gusts and isolated QLCS tornadoes will remain
possible this afternoon across portions southern IN and northern KY.

DISCUSSION...As of 2000 UTC, regional radar analysis showed a
well-developed QLCS located near the Ohio River across portions of
southern IN and northwestern KY. Several bowing segments within the
QLCS have recently produced measured severe gusts at Evansville, IN
and Henderson, KY. Area VAD/VWPs show relatively elongated low-level
hodographs with 0-3 km shear orthogonal to the line at around 35-40
kt. Despite strong veering of surface winds, the strong low-level
shear remains supportive of damaging wind gusts and QLCS tornadoes.
Surface analysis and observational trends suggest this QLCS segment
will remain within the favorable environment for the next 1-2 hours
as it tracks east northeast toward the Louisville metro area.
