...New AVIATION...

.UPDATE...
Issued at 821 PM CDT Fri Jul 8 2022

Heat headlines have been cancelled. Temps have dropped off this
evening, especially in areas that have received rain and
thunderstorms.

A few marginally severe storms occurred this evening across the
Upper Cumberland with downed limbs and such, but most of the
storms have been sub-severe with heavy downpours, lightning, and
wind gusts around 35mph. Activity has been decreasing with
sunset, but we do expect things to pick up again through the
night. A weak boundary and low pressure wave will approach from
the northwest. Even in the late night hours, adequate instability
will remain for some "strong" storms, especially across the west
half which has not been worked over by storms. Abundant
atmospheric moisture will make heavy downpours likely.

&&

.SHORT TERM...
(This afternoon through Saturday Night)
Issued at 154 PM CDT Fri Jul 8 2022

A few showers and thunderstorms have started to pop up early this
afternoon ahead of the shortwave trough and cold front that will
move through later this evening. Plenty of moisture exists at the
surface, with afternoon dewpoints in the low to mid 70s across the
area. CAMs show isolated activity this afternoon and early evening
before a larger cluster of storms moves in during the mid evening
in the north and spreads to the southeast through the early
overnight hours. Models are still showing a bit of a difference in
timing, which is to be expected due to differences in the speed of
the front/evolution of the cold pool and outflow from the
convection this evening. Larger scale models show a decline in the
instability this evening into the overnight hours, while CAMs
still show decent CAPE in the 500 to 1500 J/kg range. Deep layer
shear does pick up slightly, but still on the weaker side, so with
any strong to severe storms the main threat will be damaging wind
gusts and some hail. All models show very high PWAT values in the
2.25 to 2.5 inch range, so any training of stronger showers and
storms or slower progression will provide an isolated flooding
threat as well. Showers and storms should be out of the mid state
before sunrise Saturday.

A deeper trough will try to move southeast on Saturday, and bring
a more pronounced front during the day. With northwest flow,
models want to place the better chances for showers and storms in
the south and east where diurnal support/frontal timing will be
better. Instability will be lingering around again ahead of the
front, so some strong to severe storms with damaging wind gusts
will not be out of the question. Chances for precip should move
out during the evening, and be drier overnight with most areas
finally seeing lows get into the 60s.

&&

.LONG TERM...
(Sunday through next Friday)
Issued at 154 PM CDT Fri Jul 8 2022

Sunday will see the upper trough move southeast overhead, with
some precip chances in the far southeast during the day. Rest of
the area should be dry, and a bit cooler, with highs in the low
80s to around 90. But, this cooler trend will be short lived as
the trough moves east and a strong Plains high slowly moves east
behind. High temps by Tuesday will be in the low to mid 90s. But
thankfully, another Midwest trough will move to the southeast
Tuesday night into the day Wednesday and provide some additional
relief from the heat but also bring chances for showers and
thunderstorms on Wednesday. Shortwave disturbances aloft to our
south may keep storm chances in the far south on Thursday, but
Friday looks to be dry with temperatures around seasonal normals.

&&

.AVIATION...
(06Z TAFS)
Issued at 1239 AM CDT Sat Jul 9 2022

A complex of storms is moving south out of Kentucky and is
expected to impact the terminal overnight. Vis could drop to IFR
while storms impact the terminals. More scattered showers and
storms are expected on Saturday as a cold front moves through the
area. WSW winds will shift to the NNW/N as the front passes the
terminals. Behind the front, MVFR cigs will move in for the rest
of the taf period.
