.NEAR TERM...
(Rest of tonight and Wednesday)
Issued at 905 PM CDT Tue Aug 5 2025

A low stratus deck continues to slowly recede to the east leaving
portions of northwest AL under clear skies whereas further east
the clouds remain entrenched. Based on observational trends, our
eastern forecast zones should remain under cloud cover through the
night. Where the skies do clear, some patchy fog is possible,
especially in our typical fog prone areas. Otherwise, a tranquil
evening is in store with lows dropping down into the upper 60s
across the Tennessee Valley.

On Wednesday, the upper level trough axis shifts slightly east as
a ridge amplifies to our west. As a result, most of the Tennessee
Valley will remain dry tomorrow with the exception of a low
(10-20%) in far northeast AL. However, that may be generous given
how the precip has remained south and east of our forecast area
the last few days. Expect another day of abundant cloud cover,
except across northwest AL. This will hold temperatures below
normal for this time of year with highs in the low to mid 80s east
of I-65 and upper 80s west of I-65.

.SHORT TERM...
(Wednesday night through Friday Night)
Issued at 905 PM CDT Tue Aug 5 2025

The upper level ridge attempts to nudge its way into our western
forecast zones by the second half of the workweek. This moderates
temperatures close to climatological normals for this time of year
with afternoon highs in the upper 80s to lower 90s and overnight
lows in the upper 60s to lower 70s. A series of shortwaves will
move northeastward from the FL panhandle into the Carolinas. While
this will keep the majority of moisture east of our local forecast
area, daily low chances (20-40%) for showers and thunderstorms
may creep into northeast AL. These will be primarily diurnally
driven and are not expected to be severe.

.LONG TERM...
(Saturday through Tuesday)
Issued at 905 PM CDT Tue Aug 5 2025

Not much change in the sensible weather pattern as we head into
the weekend. The upper level trough remains nearly stationary
across the eastern CONUS. This will once again bring diurnally
driven showers and storms both Saturday and Sunday with the
greatest chances in our eastern zones. The upper level ridge
across the Mississippi River Valley is able to finally kick the
upper level trough off the East Coast by the start of next week.
This will allow for some better moisture advection resulting in
not only diurnal thunderstorms, but dewpoints will also increase
back into the lower 70s. As a result, heat index values will top
out in the low triple digits Monday and Tuesday afternoon.

.AVIATION...
(00Z TAFS)
Issued at 555 PM CDT Tue Aug 5 2025

Low-end VFR conditions this evening will gradually transition to
MVFR conditions after Midnight as low stratus builds back in and
some light fog potentially forms right before daybreak. BKN/OVC
MVFR ceilings will linger into the morning hours on Wednesday,
before lifting and scattering out during the afternoon hours --
prompting a return to VFR conditions later in the day.
