.SHORT TERM...
(Rest of today through Friday Night)
Issued at 1130 AM CDT Wed Jul 16 2025

Not a ton going on at forecast time, however we do have some
showers and storms moving across our northern half this morning.
These should be fairly unimpactful other than to say when these
clear out of any given area, the skies will clear out and the heat
and humidity will start to crank up. Additional storm development
is expected this afternoon, much like we`ve seen the last couple
of weeks -- diurnally driven activity that will die out by the
early evening hours. Of course, any of these storms will run the
risk of lightning, gusty winds and heavy rainfall.

Over the next couple of days, much of our weather influences will be
driven by a tropical wave that is moving east to west along the
northern Gulf of America and a weak shortwave just to the north of
Middle TN. The combination of the two are expected to do two things:
increase PoPs chances for our northern half and decrease them for
our southern half as weak subsidence is experienced south of I-40.
This subsidence will also drive up temperatures/dew points a few
more degrees. For this reason, I`m going to go ahead and issue a
Heat Advisory for Thursday afternoon as the coverage of 105-110 Heat
Index values are looking more likely west of the Cumberland Plateau.
This potential will exist on Friday as well, but I think we`ll take
the issuance of Heat Advisories one day at a time.

.LONG TERM...
(Saturday through next Wednesday)
Issued at 1130 AM CDT Wed Jul 16 2025

Scattered storm chances will persist right through the upcoming
weekend. It is summer, after all. Heat Index values should relax
back below 105 degrees each afternoon, however there are some
indications that by the start of next week, upper ridging will
amplify across the deep south and up into the TN/OH Valleys. While
scattered diurnal storm chances likely will not end, Heat Index
values will probably climb back into at least advisory territory.

In the end, we don`t have any organized severe weather threats over
the next 7 days, but if you have outdoor plans, keep an eye on the
sky each afternoon and stay hydrated!

.AVIATION...
(18Z TAFS)
Issued at 1252 PM CDT Wed Jul 16 2025

A combination of TSRA and SHRA is currently impacting BNA & MQY,
as well as the eastern terminals (SRB and CSV), due to a boundary
moving through Middle TN. VCTS and TEMPOs have been utilized in
various fashions for the next few hours, though it seems the worst
is over for BNA & MQY. Winds are favoring a S to SW direction at
5-8 kts unless influenced by TS activity.

Conditions once again calm this evening with light/variable winds
and perhaps some patchy fog near SRB and CSV. Tomorrow`s weather
will be similar to today, and we`ll need to see how convective
activity begins late tomorrow morning to address TAF mentioning
for TS.
