Area Forecast Discussion
National Weather Service Nashville TN
228 PM CDT Mon Aug 10 2020

.DISCUSSION...

A wet weather pattern is expected for this week. Showers and
thunderstorms are showing up on the radar mainly east of 65. This
should fill in and back fill through the evening hours...but
still only expected scattered storms. PW values remain quite high
so storms are expected to be fairly heavy in nature...along with
the potential for gusty winds. There could also be some patchy fog
for the plateau tomorrow morning.

With weak upper level flow for the next few days don/t expect much
change to the current pattern. Due to this will go a few degrees
above guidance for afternoon high temperatures. So far today highs
have been a couple of degrees above what was expected. Models show
a weak front Wednesday/Thursday and at this time will go with the
highest pops...still only low end likely. Will also go closer to
guidance temperatures for Wednesday through the weekend...which
is slightly cooler than normal for this time of year. Don/t really
see anything significant in the extended forecast. CPC is showing
around normal for temps and above normal for precipitation in the
6-10 day timeframe.

WPC guidance seems to have backed off for rainfall totals. Storm
total QPF for tonight through Sunday night looks more in the range
of less than inch to 1.5" over the plateau.

.AVIATION...
18Z TAF DISCUSSION.

VCTS expected this afternoon mainly at BNA, MQY, and CSV. Could
experience periods of lower cig and vis if a t'storm moves
directly over a terminal. Expect clearing by 02Z to 03Z for all
terminals. Another round of VCTS expected after 07Z beginning
with CKV before moving southeastward to the remaining terminals
by 10Z. There is some inconsistency of when these t'storms will
reach the area, but tried to reflect the best periods of
opportunity in the AM in the TAFs. Winds will remain from the
south to southwest in the 5 to 10 knot range with the exception of
if a t'storm were to move directly over a terminal in which case
gusts could be higher.
