.UPDATE...
FOR 00Z AVIATION DISCUSSION.

&&

.DISCUSSION...

Main severe weather threat right now is over our southern-most
counties, where a tornado warning remains in effect until 7 pm for
Lewis County, as well as parts of Maury and Hickman Counties.
Meanwhile, atmosphere over northwestern Middle has stabilized, and
have canceled four counties in our northwest from Severe Weather
Watch 089.

&&

.AVIATION...
00Z TAF DISCUSSION.

BNA/CKV/CSV...Initial line of storms is now affecting the
Cumberland Plateau with a second line of storms trailing from
Nashville southwestward into West Tennessee. Look for storms to
affect BNA & CKV through the early evening, and CSV through late
evening. Once these storms clear the mid state, we will be rain-
free during the overnight period through tomorrow. Look for low
ceilings to develop toward morning as wrap-around moisture enters
the mid state.

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