.UPDATE...
FOR EVENING DISCUSSION.

&&

.DISCUSSION...

Latest radar imagery shows a broken line of showers and
thunderstorms extends from our southwest corner to near Crossville
this evening. Despite strong deep layer shear and mid level lapse
rates over 7 C/km, storms have remained sub-severe due to minimal
instability in place, with only 205 J/Kg of MLCAPE on our 00Z
sounding. Expected the bulk of activity to exit the area by
midnight with the remaining showers out of the cwa by 09Z at the
latest. Have updated pops based on latest timing, and also tweaked
other grids with latest obs. No other significant changes were
made.

&&

.AVIATION...
18Z TAF DISCUSSION.

BNA/MQY/CKV/CSV...A cold front is marching across Middle Tennessee
early this evening, with showers lined up along the front and
scattered cells ahead. Wind shift across the surface boundary is
quite abrupt, and so we can expect much cooler, drier air to begin
advecting in rather quickly. Look for the showers to end with the
fropa, although ceilings will remain MVFR/IFR for a few more
hours. Conditions will become VFR by Thursday morning.

.OHX WATCHES/WARNINGS/ADVISORIES...
