...New SHORT TERM, LONG TERM...

.SHORT TERM...
(This afternoon through Monday Night)
Issued at 204 PM CDT Sun Jul 2 2023

Showers and thunderstorms are beginning to increase in coverage
and intensity this afternoon across North Alabama and Southern
Middle Tennessee. This area will be Round #1 for severe weather
this afternoon with damaging winds and hail up to the size of
quarters being the main threat as there's plenty of instability to
utilize. Areas along I-40 and north will likely have to wait
until Round #2 coming down from Kentucky with possible convection
developing out ahead of this line for late this afternoon/evening.
The Round #2 of storms will push through all of Middle Tennessee
and exit the area after midnight.

All in all, it's going to be a fairly active weather day and
night across Middle Tennessee so be sure to monitor a reliable
weather source and radar before venturing out or partaking in any
outdoor activities. We should be used to this drill since this
marks Day 3 of 3 for these kind of storms.

With storms exiting the area after midnight, Monday will finally
be met with what we can call a typical summertime weather pattern
with afternoon and evening pop up showers and thunderstorms
possible...with the best chances across Southern Middle TN. With
the upper trough and focus off to the east, we welcome the
disorganization of pop-up storms for once. Highs will be in the
mid 80s to 90F. Honestly, this is the day to enjoy outside as rain
chances are significantly lower and temperatures are "not as
bad". Any storms that develop will quickly die off Monday evening
with Lows in the mid 60s to 70F expected Monday Night.

&&

.LONG TERM...
(Tuesday through next Sunday)
Issued at 204 PM CDT Sun Jul 2 2023

More of the typical summertime pop-up thunderstorms can be
expected on the 4th and Wednesday although think a lot of Middle
Tennessee will skirt out the holiday and day after as mostly dry.
Best chances will be across Southern Middle Tennessee on both
days. Highs in the mid 80s to lower 90s can be expected.

Once again, Thursday advertises that typical summertime pattern,
but it looks as though what was once promised as a potentially
nice Friday and weekend has the area in Northwest flow pattern
again. So have increased rain chances for Friday and the weekend
as medium range models and ensembles are setting up the area for
potential complex after complex late next week. Here's hoping that
it changed once, so maybe it can change again since this pattern
is a difficult one to forecast in the summer. Typically, it's
incredibly difficult to get timing and location exact, and most
of the time, impacts will likely be in the form of damaging winds.
Stay tuned.

.AVIATION...
(18Z TAFS)
Issued at 1226 PM CDT Sun Jul 2 2023

Scattered storms are expected to develop over the next couple of
hours and could impact the terminals. Exact timing and positioning
of the storms is uncertain at this point so only included tempo
groups at this time and will amend as necessary. If a terminal is
impacted, visibilities could drop to IFR/LIFR and winds could
gusts as high as 40-50 kts. Showers and storms are expected to
decrease in coverage prior to midnight. MVFR cigs could develop at
SRB/CSV in the morning with only sct Cu further west.
