.NEAR TERM...

(Today)
Issued at 215 AM CDT Thu Sep 19 2024

Fog, once again, will be the main focus of the near term forecast.
Satellite observations show slightly moister air in place with
mostly clear skies. With winds calming over the next several
hours, fog is very likely as dew point depressions are already in
the 0-2 degree range. While patchy fog will be possible
everywhere, best chances of locally dense fog will be along and
west of I-65, especially along the TN River. Any fog that does
form will dissipate a few hours after sunrise.

The remainder of the day will be rinse and repeat from the
previous days as high pressure remains the dominating feature.
Highs will be a few degrees warmer than yesterday in the mid to
high 80s. Subsidence will greatly suppress any other impact with
with skies mostly clear and very light wind through the remainder
of the day.

(Tonight through Sunday)
Issued at 215 AM CDT Thu Sep 19 2024

Through the short term forecast mid level ridging will build in
from the SW maintaining high pressure as the dominating weather
feature. This will support a gradual warming trend through the
weekend with highs building from the low 90s on Friday to the low
to mid 90s Saturday and Sunday. Continued subsidence from high
pressure will promote mostly clear skies and calm winds making
for a nice, if a little warm, weekend.

(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.

(06Z TAFS)
Issued at 1240 AM CDT Thu Sep 19 2024

Fog will be the main threat to VFR conditions through sunrise. MSL
will be most susceptible for fog thus went lower with the
visibilities. Will continue to monitor HSV should lower
visibilities than forecast warrant an amendment. Fog should mix
out within a couple hours of sunrise with VFR conditions
prevailing through the remainder of the TAF period.
