National Weather Service Nashville TN
1258 PM CDT WED AUG 3 2016

.UPDATE...
FOR 18Z AVIATION DISCUSSION.

&&

.DISCUSSION...

No significant changes needed to this morning's forecast package.
Will only make a few minor tweaks to very short term temps and dew
points. Still don't expect TOO many storms this afternoon but most
of what does develop will probably be across the west half of the
mid state. In fact, a few showers and a thunderstorm were already
creeping southeastward across the Tennessee River at 1630Z.

&&

.AVIATION...
18Z TAF DISCUSSION.

Scattered showers and storms moving into western middle TN and
through western KY early this afternoon will drift southeastward
next few hours...so added VCTS to KCKV. Only isolated TSRA
elsewhere across the region this afternoon and evening. Had
noticeable fog this morning and kept brief mention of light fog
again for a few hours near sunrise Thursday. Could cause a moment
or two of MVFR.  Isolated to scattered storms are possible early
Thursday as weak upper disturbance drops toward the region from
the northwest. Included VCTS at KCKV in the morning but left out
of KBNA/KCSV forecasts for now.

&&

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