.NEAR TERM...
(Tonight)
Issued at 156 PM CDT Sat Oct 19 2024

High pressure aloft and at the surface will maintain mostly clear
skies and light winds through the duration of the afternoon. Temps
will peak in the low to mid 70s before cooling off with sunset.

Tonight, clear and calm conditions will present a favorable set up
for radiational cooling with temps dropping down into the low 40s.
Low dew point depressions in association with the clear and calm
conditions will support patchy fog development. Chances for patchy
fog will be best along waterways and in protected valleys during
the early morning hours. Any fog that does develop will dissipate
shortly after sunrise.

.SHORT TERM...
(Sunday through Tuesday)
Issued at 156 PM CDT Sat Oct 19 2024

High pressure will remain the main impactful feature through the
duration of the short term forecast. This will support several
additional days of clear and calm conditions with a gradual
warming trend taking place through the start of the week. Daytime
highs will rise from the high 70s on Sunday to the low 80s by
Tuesday. Overnight lows will follow a similar trend rising from
the low to mid 40s tonight to the high 40s and low 50s by Tuesday
morning.

.LONG TERM...
(Tuesday night through Friday)
Issued at 306 AM CDT Sat Oct 19 2024

An upper level low currently residing in the southwest US is
forecast to continue northeast into the Great Lakes region and
expand into a shortwave trough, forcing the previously mentioned
ridge eastward and bringing a cold front into the Tennessee
Valley by late next week. Continued to stick with blended guidance
and a resultant dry forecast due to lack of moisture in the
extended period. Highs during this period are forecast to be in
the 70s to 80s with overnight lows in the 40s to 50s.

.AVIATION...
(18Z TAFS)
Issued at 1227 PM CDT Sat Oct 19 2024

High pressure at the surface and aloft will control the general
weather across the Tennessee Valley into Sunday, thus VFR flight
conditions should continue. Light east winds this afternoon are
forecast to become light/variable tonight. There is a risk of fog
developing before daybreak Sun. This was not included in the TAF
given low confidence of if/when it could form.
