...THERE IS AN ENHANCED RISK OF SEVERE THUNDERSTORMS FROM PARTS OF
THE OH VALLEY INTO THE LOWER MS VALLEY...
...SUMMARY...
Thunderstorms capable of damaging winds and a few tornadoes will
continue into late tonight from parts of the Ohio and Tennessee
Valleys into the lower Mississippi Valley.
...OH/TN Valleys into the lower MS Valley...
An extensive QLCS, with multiple embedded bowing segments, will
continue moving eastward into late tonight. The northern portion of
the QLCS (roughly from northern AL into the OH Valley) will be
moving into a less unstable environment with time, though the
well-defined rear-inflow jets noted on recent NQA and PAH VWPs may
allow the bowing segments to persist into late tonight before
instability wanes completely. Damaging wind gusts will be the
primary hazard with these bowing segments, though a brief tornado or
two remain possible with stronger embedded circulations.
Further south, from LA into MS and southwest AL, where there is a
more substantial reservoir of low-level moisture and instability,
some severe threat will likely persist into the overnight hours. The
primarily linear mode will result in a continued threat of
strong/damaging wind gusts and brief tornadoes associated with
embedded circulations. Discrete cells have thus far struggled to
intensify before becoming absorbed into the line, but low-level
shear will remain sufficient to support a conditional tornado threat
with any longer-lived supercell that can develop ahead of the main
QLCS.
