.NEAR TERM...
(Tonight)
Issued at 235 PM CDT Thu Sep 19 2024

Daytime heating of available moisture has resulted in the
formation of fair weather cumulus across the greater Tennessee
Valley. Somewhat deeper moisture to our east, and the influence
of terrain has resulted in a few light showers popping up, mainly
over parts of eastern Tennessee, western North Carolina and
northern Georgia. We cannot totally rule out a brief showers over
some of our more eastern areas before the evening, but chances are
too low to include in the forecast. Area temperatures as of 2 PM
ranged in the mid/upper 80s with light/variable winds.

Clouds over the Valley should fade as we go into the evening. Lows
by daybreak Friday should cool into the low/mid 60s with nearly
calm conditions. Generally clear skies, light winds, and longer
nights are becoming more favorable for the formation of fog. MOS
output has been showing this potential the past few days, however
not much fog has formed. With the base criteria needed for fog
being met, will keep a mention in the forecast. We are also
getting into a more foggy prone time of year.

.SHORT TERM...
(Friday through Sunday)
Issued at 235 PM CDT Thu Sep 19 2024

Dry conditions, with a warming trend will continue as we go into
the upcoming weekend. As the general atmosphere stagnates and
upper level ridging builds in from the SW, daily high and low
temperatures should likewise rise. High temperatures on Friday
should warm to around 90 degrees, and into the lower 90s during
Saturday and Sunday. Lows in the period should range in the
mid/upper 60s. Heat index readings on Sat/Sun into the low/mid
90s are expected.

.LONG TERM...
(Sunday night through Wednesday)
Issued at 215 AM CDT Thu Sep 19 2024

A slightly more active pattern will begin next week and an
low pressure system pushes east across the CONUS. The shift will
be gradual as the low pressure and associated front drifts
towards the area. Through the long term rain chances will slowly
build each day from about 10%-30% by Wednesday in response to the
approaching front. In turn this will result in slightly more cloud
cover and a gradual decrease in temps from the low 90s on Monday
to the mid 80s on Wednesday. Models have yet to converge on exact
details of the frontal passage regarding higher rain chances, have
maintained blended guidance for now with subsequent forecast
packages likely having a better idea as this moves into the short
term.

.AVIATION...
(18Z TAFS)
Issued at 1245 PM CDT Thu Sep 19 2024

Surface high pressure over the region should continue producing
light winds at the terminals. Generally clear skies tonight along
with light winds could result in patchy fog forming in the
predawn. Confidence for fog is lower at KHSV than at KMSL. Any fog
that forms should dissipate shortly after sunrise Fri AM, with
VFR weather expected for the rest of the TAF.
