Concerning...Tornado Watch 68...70...

Valid 282159Z - 282300Z

The severe weather threat for Tornado Watch 68, 70 continues.

SUMMARY...Tornado threat will shift east of WWs 68/69 over the next
few hours. New tornado watch may be warranted soon.

DISCUSSION...Latest NAM guidance suggests LLJ will strengthen across
the western TN Valley this evening as 500mb speed max increases in
excess of 100kt from AR into western KY over the next 03-06hr.
Earlier trends suggesting a QLCS might be evolving across AR now
favor a mix of discrete supercells and clusters. This may be in part
to expected strengthening wind fields. Over the next few hours,
ongoing corridor of supercells over eastern portions of ww68 should
approach, then spread east of the watch. This will necessitate a new
tornado watch soon.
