.NEAR TERM...
(Rest of tonight and Sunday)
Issued at 1052 PM CDT Sat Jul 5 2025

Isolated later afternoon convection that impacted a few spots
across the Tennessee Valley have either faded or moved west of the
region. The area otherwise was between an upper low over the NE
Gulf of America, and a weakening upper ridge over the Mid South to
western Ohio Valley. At the NE end of the upper low was Tropical
Storm Chantal located about 80 miles ESE of Charleston SC. This
system should move ashore South Carolina in the overnight between
Charleston and Myrtle Beach. It should have no direct impact on
our sensible weather.

Local temperatures have cooled into the 70s to around 80 under
generally clear skies. The clear skies, along with increasing
relative humidity values as the temperature and dewpoint converge
should result in the formation of fog in the late night. Thus in
agreement with MOS guidance, have added fog to the forecast for
the late night. Think the fog will be more prevalent over NW to
north central Alabama, with lesser chances more to the east thanks
to slightly drier air filtering in. Low temperatures tonight
should range from the upper 60s east to lower 70s west.

Another very warm to hot day is in the forecast to start a new
week. Under generally sunny to party cloudy skies, high
temperatures Sunday afternoon should rise into the low/mid 90s.
This heat plus dewpoints around 70 will produce heat index values
from the mid 90s to 104 degrees. Will hold off on a Heat Advisory
at this time. This heat and resultant instability will produce
CAPE values in 1000-3000 J/kg, which could lead to isolated
showers and thunderstorms in the afternoon. Coverage should be
less than it was today.

.SHORT TERM...
(Sunday night through Tuesday)
Issued at 1052 PM CDT Sat Jul 5 2025

Another muggy night is forecast for the Valley. Any shower
activity should quickly fade after dusk Sunday night. An almost
carbon copy of tonight, with lows before daybreak Monday in the
upper 60s and lower 70s with light winds. Will add more late night
patchy fog. Monday should bring more very warm to hot conditions,
with highs in the low/mid 90s, and similar heat indices to Sunday.
The heat and available moisture will bring more isolated showers
and thunderstorms Mon afternoon and early evening. Monday night
lows should cool into upper 60s/lower 70s again.

Surface high pressure should be positioned east of the area Monday
and Tuesday. A southerly flow rounding the western periphery of
the high will return somewhat deeper moisture across the area.
This moisture will result in higher chances for showers and storms
on Tuesday.

.LONG TERM...
(Tuesday night through Saturday)
Issued at 1052 PM CDT Sat Jul 5 2025

A somewhat of a pattern change is expected for the midweek and
beyond, as a strong upper ridge develops over the Desert SW, and
more troughing over the eastern CONUS. With greater lower level
moisture from the Gulf moving northward, higher chances for
showers and thunderstorms is expected for the mid week into
Saturday.

Muggy conditions are expected Tue night, with lows in the lower
70s. With more clouds and higher rain chances, high temperatures
will be a tad cooler, ranging in the upper 80s to lower 90s for
the latter half of the work week. Rain chances should follow a
somewhat diurnal trend, higher in the afternoon and evening.
