.DISCUSSION...

Late this morning, some fairly strong thunderstorms had developed
across Giles County and surrounding areas. The storms had formed
in an area of 30-35KT low level bulk shear with 500-1000 J/kg
cape. As the low pressure and cold front continue to move east,
it looks like the best combination of cape reaching 1000 and 35KT
bulk shear will shift east northeast through the next couple of
hours. So, we will have to watch areas around Shelbyville,
Manchester, Woodbury, and possibly up to Murfreesboro for some
strong storms and perhaps a couple of marginally severe storms
with wind gust and hail potential. That axis will move on up to
Cookeville and Crossville by mid afternoon.

&&

.AVIATION...
18Z TAF DISCUSSION.

Cigs and visibilities are expected to continue bouncing between
MVFR and IFR this afternoon as precip moves through the area.
Storm have pushed past I-65, so mainly showers expected for CKV,
MQY, and BNA this afternoon and evening. CSV could still see some
strong storms this afternoon with heavy rainfall and gusty winds.
Storm potential should decrease by 00z at CSV. Showers will taper
off from west to east overnight leaving behind some light fog as
winds calm. Sunday should be much nicer with mostly clear skies
in the forecast.

.OHX WATCHES/WARNINGS/ADVISORIES...
NONE.
