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

.SHORT TERM...
(This afternoon through Friday Night)
Issued at 156 PM CDT Thu Jul 28 2022

Isolated showers and storms have developed this afternoon and will
continue to do so through the afternoon. Enough instability and
deep layer shear are in place for some strong to severe storms
capable of producing damaging wind gusts as well. The main threat
remains heavy rain and flooding potential with high PWAT values of
2 inches or higher now into the weekend. A cold front to our north
will continue to move southward, and CAMs have activity ahead of
the front moving in later this evening and overnight. Mean wind
is generally 15 knots or greater, so the storms should move fast
enough to not pose a flooding threat themselves, but, with near
easterly storm motion nearly parallel to the orientation of the
front, its the training of multiple showers and storms that will
pose the flooding threat. This is especially true tonight and
through the day Friday as the front continues southward. Soundings
show high freezing levels around 16kft and continued instability
overnight, allowing for the potential to see strong updrafts and
efficient heavy rain producing storms putting down 1 to 3 inches
of rain per hour rainfall rates. Any location that sees multiple
rounds of heavy rain from stronger storms passing through will be
at a higher risk for flooding from this afternoon through the day
Friday.

Tonight and into the morning hours Friday CAMs really focus on
the northern half of the mid state, and have activity develop
southward just ahead of the front during the day Friday. As long
as the front continues to move southward during the day, the
training of storms should be more isolated, but if the front
stalls a bit, the training and flooding risk will increase. Will
definitely have to keep an eye on CAM trends and where the front
sets up tonight for flooding potential.

.LONG TERM...
(Saturday through next Thursday)
Issued at 156 PM CDT Thu Jul 28 2022

On Saturday another shortwave will approach the area and increase
precip chances during the day. The cold front from tonight and
Friday's system should move further south, but if it stalls near
our area, parts of the southern mid state may see additional
rainfall. Sunday is showing a similar story with a shortwave
moving in from the northwest, and yet another wave keeping in high
precip chances for Monday. When its all said and done, we are
still looking at an additional 1 to 3 inches of rain across the
area, with some locations possibly seeing up to 5 inches if
multiple rounds of heavier rain fall over isolated areas.
Lingering precip chances hold on Tuesday, but high pressure tries
to win out for the remainder of the long term and unfortunately
bring the warmer temps back. Currently have highs in the mid 90s
returning Wednesday and Thursday with some drier weather making
its return as well.

.AVIATION...
(18Z TAFS)
Issued at 1210 PM CDT Thu Jul 28 2022

Scattered cells are popping rapidly across Middle Tennessee, so
we've included TEMPO showers for the next few hours to handle the
increase in convective activity. Overnight, a more organized line
of showers and thunderstorms looks to sweep through the mid state.
Showers may even extend into the morning hours with some lingering
MVFR ceilings.
