(Tonight)
Issued at 100 PM CDT Mon Sep 16 2024

Dry air is finally working its way into the area this afternoon
and is helping to dissipate cloud cover across the region, making
for a pleasant rest of the day. Winds will decouple overnight and
the combination of these very light winds and the clear sky will
allow for good radiational cooling as temperatures fall back into
the upper 50s to lower 60s. Additionally, moist boundary layer
conditions from the recent rainfall may allow for some patchy fog
development in sheltered river valleys and across the Bankhead
National Forest.

The Tennessee Valley will remain wedged between a building ridge
to the west that will attempt to push into the area by midweek and
the remnant potential tropical system meandering over the
Carolinas. The end result will be a continued dry forecast, with a
gradual warming trend taking shape by Wednesday/Thursday as highs
climb back into the mid to upper 80s. Continued clear/calm
conditions and saturated soils due to recent rainfall (especially
in northwest Alabama), patchy fog will likely remain in the
forecast each night during this timeframe.

.LONG TERM...
(Thursday night through Sunday)
Issued at 250 AM CDT Mon Sep 16 2024

The upper ridge will shift even farther east by Friday, and will
result in temps nearing 90 degrees as we head into the weekend.
At the sfc, high pressure will sink southeast through the Ohio
Valley and will further enforce a dry forecast through Sunday.
The next feature to watch will be an upper low that will shift
west into SC and GA by the end of the weekend, and could result
in an increase in clouds. Low level northeasterly flow will also
result in slightly cooler temperatures on Sunday, topping out in
the low to mid 80s. Overnight lows will range from the low to mid
60s each night.

.AVIATION...
(00Z TAFS)
Issued at 656 PM CDT Mon Sep 16 2024

Light and variable winds and clear skies at the terminals are
expected tonight. This will likely allow for VSBY restrictions due
to fog at both terminals. Drier air moving into the area may keep
it patchy and only MVFR. However, KMSL may see a bit thicker fog
if dewpoints stay higher there. A tempo group for MVFR VSBYS was
included from 08Z to 12Z at both terminals for now. Winds should
pick up to between 5 and 10 knots after 15Z.
