(Tonight)
Issued at 839 PM CDT Thu Sep 19 2024

High pressure promoting mostly clear and calm conditions overnight
across the Tennessee Valley. Once again, this is a good setup for
radiational cooling as temperatures fall back into the low to mid
60s in most locations. Late tonight into early Friday morning,
patchy fog may also develop -- especially in sheltered river
valleys around sunrise. Only minor tweaks were made to the
forecast based on the latest obs/trends as everything remains on
track.

.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...
(00Z TAFS)
Issued at 705 PM CDT Thu Sep 19 2024

VFR conditions this evening may give way to MVFR to perhaps
localized IFR conditions due to patchy fog at both terminals
between 09-12z. After sunrise, any fog that does develop will
dissipate and a return to VFR conditions will occur through the
period.
