.DISCUSSION...

Latest radar imagery shows widespread light to moderate rain with
a few embedded thunderstorms continues to spread eastward across
Middle Tennessee, now entering the Upper Cumberland. Regional
radar imagery shows activity still extends westward into Arkansas,
so off and on rain with some lightning and thunder will continue
through the night before ending from west to east after sunrise
Tuesday morning. Have raised pops this evening and tonight in
line with latest HRRR model runs. Surface observations show
frontal boundary has sagged southward to just south of the
Alabama border, with all of Middle Tennessee now in the stable
cool surface layer north of the front. Temperatures will therefore
remain steady or only drop slightly the rest of the night. OOZ
OHX sounding shows elevated instability up to 250 J/Kg is present
north of the front along with deep layer shear up to 55 knots, so
cannot rule out an isolated strong storm or two with small hail
overnight - mainly across southern counties closer to the surface
front.

.AVIATION...
00Z TAF DISCUSSION.

A boundary is situated across Southern TN and a low will ride
along this boundary tonight and tomorrow. This will give the
possibility for thunderstorms tonight area wide...with a few
strong storms possible across the south. The main threat will be
hail and wind.

With the boundary in place all TAF sites will see mainly IFR
conditions. It might even be LIFR around 12Z and in and around
thunderstorms. Hopefully visibilities will improve after 18Z and
ceilings will improve to MVFR around 00Z Wednesday.

.OHX WATCHES/WARNINGS/ADVISORIES...
