Areas affected...portions of central Kentucky into northern
Tennessee

Concerning...Tornado Watch 315...

Valid 261517Z - 261645Z

The severe weather threat for Tornado Watch 315 continues.

SUMMARY...The severe threat continues across Tornado Watch 315. A
bow echo will continue to progress eastward with a damaging wind
threat, and a few more QLCS tornadoes remain possible.

DISCUSSION...A well organized bow echo MCS, with a history of severe
wind gusts, wind damage, and occasional QLCS tornadoes, continues to
rapidly track eastward across portions of the TN Valley. At the
moment, the bow appears slightly less robust compared to earlier
stages, perhaps due to gradually waning instability with eastward
extent. Nonetheless, the Kentucky mesonet continues to show
widespread 45-55 mph wind gusts occurring with the bow, with
regional radars also depicting occasional, brief QLCS circulations
developing. With adequate vertical wind shear, over 2000 J/kg MLCAPE
and weakening MLCINH (given diurnal heating) preceding the bow,
damaging gusts (perhaps exceeding severe limits at times) should
continue across much of the rest of KY and northern TN. A couple of
additional QLCS tornado also cannot be ruled out.
