.UPDATE...
FOR 06Z AVIATION DISCUSSION.

&&

.DISCUSSION...

Area of storms and showers continues to push east and slightly
southward. We have seen the southwestern tail weaken over the last
hour, but some pockets of strong winds are still possible for
areas east of I-65. After midnight additional storms may push into
the mid-state from the west as a mid level trough moves closer
and provides some overnight lift. This activity should be slightly
weaker with less coverage than we saw this evening. However, with
some instability still available overnight and models indicating a
slight uptick in bulk shear, strong wind gusts and a few
organized strong or severe storms will remain a possibility. So
keep the weather radios on and phones nearby just in case. Updated
pops and weather grids to reflect the continued overnight storms.
Will gradually remove counties from the Severe Thunderstorm Watch
as storms push east.

&&

.AVIATION...
06Z TAF DISCUSSION.

Expect a very active TAF with amendments for VIS and CIGS at all
sites as showers and thunderstorms continue to move through
tomorrow. Spotty TSRA early will give way to a complex of storms
tracking across the southern portions of the mid-state. BNA and
MQY have best chance of seeing impacts in the 08Z to 14Z time
frame, with lesser chances at CKV and CSV. After 18Z, models
indicate a gradual clearing from west to east with light/variable
winds late.
