(Today)
Issued at 354 AM CDT Mon Aug 11 2025

An overall nice early August day is in store across the Tennessee
Valley. Upper level ridging continues to persist overhead and as a
result, a mostly dry forecast is once again expected. The one
exception to this is in northeast AL where a low chance (20-30%)
of an afternoon shower or thunderstorms is possible. The good news
is that the coverage should remain quite low and no severe storms
are anticipated. Some weak moisture advection will raise dewpoints
back into the lower 70s and combined with afternoon highs upper
80s to lower 90s, heat indices will be in the mid to upper 90s.
The highest values will be in northwest AL.

(Monday night through Wednesday)
Issued at 1018 PM CDT Sun Aug 10 2025

The Tennessee Valley will remain sandwiched between a trough to
the north and west and a weak area of high pressure to the south
and east. Southerly flow aloft will promote a gradual moistening
of the atmosphere, with additional cloud cover and shower/storm
chances increasing to 60-70% for both Tuesday and Wednesday. Very
weak shear values will mean this activity will be poorly organized
and "pulse" like in nature. A few storms each afternoon could
become locally strong, with gusty winds and heavy downpours being
the main threat. Highs in the mid 80s to lower 90s will be common
both days, with temperatures trending a touch lower given the
higher cloud cover and rain chances.

.LONG TERM...
(Wednesday night through Sunday)
Issued at 1018 PM CDT Sun Aug 10 2025

A return to zonal flow aloft late this week into the weekend, with
an area of high pressure noted across Florida. Plenty of moisture
underneath that ridge will allow for medium (30-50%) chances for
showers and storms each day. However, the bigger story will be the
gradual warming trend as temperatures climb into the low to mid
90s during this timeframe, especially by the weekend. Combined
with dewpoints in the low to mid 70s, this will be push heat index
value near or above Advisory criteria, with heat index values
between 100-105 degrees being common and some locations climbing
above 105 degrees. Heat products may need to be considered for
parts of the area by Friday through Sunday.

Some low level stratus has developed early this morning east of
I-65 and is slowly spreading to the west. MVFR ceilings should
begin to mix out quickly after sunrise bringing a return to VFR
for the remainder of the TAF period.
