The episode as NWS HUN wrote it up.

(Rest of Today and Tonight)
Issued at 928 AM CDT Wed Aug 13 2025
The most immediate threat this morning is the increasing risk for
flash flooding across portions of the Tennessee Valley. Both radar
and rain gauges indicate that 2-2.5" have fallen this morning
across portions of southern middle TN with additional rain and
thunderstorms forecast this morning and afternoon. A Flash Flood
Watch has been issued for all counties north of the TN River plus
Marshall and DeKalb counties in NE AL. These storms are being
fueled by troughing over the MS River Valley and southern Plains
that will push east today as high pressure moves south over the
western Atlantic. Ahead of the increased convergence lies an
airmass with PWATs in the 2-2.2" range. This will make for
efficient rainfall producers throughout today and flooding will be
the main concern. Those traveling or spending time outdoors today
will need to pay close attention to the forecast/radar in case
travel becomes hazardous and lightning becomes a threat for those
outside.
With the increase in clouds and storm coverage, afternoon highs
will be limited to the mid to upper 80s across the area aside from
far NW AL where temps may climb to the 90 degree mark. The higher
humidity will support afternoon heat indices near 100 degrees,
especially over NW AL where better chances for clearing exist.
Rain chances will lower significantly overnight with a dry
forecast expected. Fog development is not expected currently with
dense cloud cover overnight, but saturated soils will support fog
if cloud cover is less than currently forecast. Lows will fall to
the lower 70s.

.SHORT TERM...
(Thursday through Friday)
Issued at 928 AM CDT Wed Aug 13 2025
We will begin a bit of a pattern shift during the short term
period as low pressure off the northern Atlantic coast is finally
pushed north and the upper trough over the eastern US becomes less
pronounced. At the same time, high pressure will build west over
the Gulf while another high shifts east through the central Plains
and into the Midwest. This will ultimately work to lower rain
chances each day while also increasing temps as we head into the
weekend. Although rain chances will be lower Thursday (capped at
40%) we will still have to monitor for flooding especially in
areas that receive heavy rainfall today. Rain chances lower to
20-30% on Friday as highs reach the low to mid 90s and heat
indices approach the 105 degree mark.

.LONG TERM...
(Friday night through Tuesday)
Issued at 1041 PM CDT Tue Aug 12 2025
A strong area of high pressure will remain the dominant weather
feature across the Tennessee Valley this weekend into early next
week. Subsidence from the ridge will largely suppress convection
and cloud cover. As a result, high temperatures will return to
the low to mid 90s each day, with a few locations potentially
reaching the upper 90s by Sunday/Monday. The combination of these
very warm temperatures and dewpoints in the low to mid 70s, will
create heat index values between 100-105 degrees across much of
the area, including several locations above 105 degrees. This will
create moderate to major heat impacts during this window. Heat
Advisory products may be needed for portions of the area during
this time frame, particularly in northwest/north central Alabama
and those with plans this weekend should keep heat safety tips on
their mind.

Low ceilings at or below 010agl (IFR) have developed. Also,
multiple clusters of +SHRA and a few TS have also developed and
should continue to expand this morning. Ceilings will climb
through the 010-020agl (MVFR) range by 15Z and above 030agl by 17Z
with a return to VFR. However, scattered to numerous SHRA and
TSRA will persist into the afternoon hours.
