.SHORT TERM...
(Tonight through Wednesday Night)
Issued at 1101 PM CDT Mon Jul 14 2025

A summer like pattern has been set up over Middle TN and it looks
to stick around for awhile. We have weak zonal flow over the
northern US and this will keep much of the same weather for our
area. Patchy fog will be possible tonight especially for areas
that saw rainfall today. Then we will once again see scattered
showers and thunderstorms develop in the afternoon and continue
into the early evening. CAMs are showing activity a little less
widespread tomorrow with the better chances staying to our north
but still plan on hit and miss storms in the afternoon. It will be
a high CAPE low shear environment. The threat for severe storms
will be low but can`t rule out gusty winds with any of the
stronger updrafts. PWATs will remain high in the 1.60-2.0" range.
Given the slow storm motion and high PWATs localized flash
flooding will be possible with any of the strong longer lasting
cells. Highs will be in the low to mid 90s with dew points in the
mid 70s, this will push afternoon heat index values to around or
just above 100.

Mainly dry conditions Tuesday night with lows once again in the
low to mid 70s. Not a lot of change in the forecast for Wednesday.
We will once again see scattered afternoon and early evening
thunderstorms. Similar to Tuesday the severe threat will be low
but heavy rain and maybe some gusty winds with any of the stronger
cells. Highs in the low to mid 90s with afternoon heat index
values between 100 and 105.

.LONG TERM...
(Thursday through next Tuesday)
Issued at 1101 PM CDT Mon Jul 14 2025

As we head into the extended part of the forecast we will see very
little change. Summer like conditions remain in place. Daily
afternoon showers and thunderstorms will continue into the
weekend and next week. Weak troughing will develop over eastern
Canada over the weekend and that will help to bring some lower
heights and maybe knock a few degrees off of our highs, instead of
low to mid 90s we will see upper 80s to lower 90s.

.AVIATION...
(06Z TAFS)
Issued at 1152 PM CDT Mon Jul 14 2025

Patchy fog will be possible through 13z and will bring MVFR/IFR
conditions at times mainly for KCKV and KMQY. The fog could be
more dense over the Plateau and periods of IFR conditions will be
possible. BNA may see a brief period of MVFR conditions due to fog
between 10 and 12z. Scattered thunderstorms will be possible
after 17z, with them being hit and miss the chance of a storm
hitting the terminal is under 30% and it was left out of the TAF.
Light winds tonight becoming southwesterly tomorrow afternoon up
to 6 knots.
