Area Forecast Discussion
National Weather Service Nashville TN
912 PM CDT Tue Sep 1 2020

.UPDATE...
FOR EVENING DISCUSSION.

&&

.DISCUSSION...

Showers and storms have moved off to the east, with some areas
receiving up to around 2.5 inches of rainfall causing some
flooding south of Nashville. Additional shortwave trough looks to
bring some additional chances for showers and storms overnight,
mainly in the northwest. CAMs do show some additional convection
during the overnight hours, with some instability left over around
the area and decent deep layer shear. Main threat will be if any
showers travel over any saturated grounds from earlier rainfall,
and additional flooding potential arises. But, there may be some
strong storms that develop and can not completely rule it out.
Current CAM consensus does bring in some showers/storms in the
northwest around 11 pm or so, and carrying across the northwest
and north of I-40 through the overnight hours. Adjusted pops and
near term forecast to line up with current guidance. Rest of
forecast is on track.

&&

.AVIATION...
00Z TAF DISCUSSION.

BNA and MQY are slowly returning to VFR conditions after a strong
line of t'storms moved through. CSV can expect periods of VCTS due
to t'storms passing over the area by 00Z. Should a t'storm move
directly over the terminal, periods of IFR will be possible.
Expecting VFR conditions to prevail at all terminals by 02Z. VCSH
will return to CKV around 06Z before moving towards BNA/MQY by
08Z. Should see a break in VCSH/VCTS around 14Z before additional
VCTS in the afternoon around 22Z for BNA and MQY.

Winds will begin to shift from southerly to more southwesterly in
the early morning hours. By mid-morning, expect winds around 10kts with
gusts to 15kts at all TAF sites.
