.NEAR TERM...
(Tonight)
Issued at 145 PM CDT Fri Jul 8 2022
Convection over the central TN Valley has been a little slower to
develop this afternoon compared to the last couple of days. But,
some showers/tstms are trying to develop in some spots and with
the abundant latent heating in place, additional convection should
be able to form later this afternoon. This activity will again be
very pulse in nature given little/if any forcing/shear in place.
But, a few stronger storms certainly remain possible, with the
capability of gusty winds and brief heavy rainfall. Rain chances
though will continue thru tonight, as a weak frontal boundary
approaches from the north.
Otherwise, the upper ridge pattern which had been in place over
much of the region this week is beginning to shift a bit to the
west. Still, current temp trends have managed to climb into the
lower/mid 90s, with heat indices near/just above 105F in some
spots. These temps will likely go up a few more degrees before the
onset of the evening hrs. In any case, the Excessive Heat Warning
or Heat Advisory currently in place is set to expire at 7PM this
evening. Temps then look to fall into mainly the lower/mid 70s by
early Sat morning.

.SHORT TERM...
(Saturday through Monday)
Issued at 145 PM CDT Fri Jul 8 2022
The front will continue to gradually settle into the area during
the day Sat, as the upper ridge axis continues to retrograde to
the west. This should allow more of a NW flow regime to develop
over much of the region. Weak upper disturbances traversing SE
within the flow pattern, coupled with the weak convergence along
the sfc front in place, should allow showers/tstms to increase
thru the day. A few stronger storms are certainly possible, with
again gusty winds and locally heavy rainfall the main wx threats.
Afternoon highs Sat look to be more in the lower/mid 90s, with max
heat indices around 100-104F in some spots.
These showers/tstms will continue into the evening hrs Sat, before
rainfall begins to taper off some to the SW. With the front moving
a little more to the south, slightly cooler/drier air will filter
into the mid TN Valley, with highs Sun/Mon in the upper 80s/near
90F. Lows both Sat/Sun nights look to fall in the upper 60s/near
70F for most spots.

.LONG TERM...
(Monday night through Friday)
Issued at 145 PM CDT Fri Jul 8 2022
Isolated/scattered showers/tstms return to the forecast starting
Tue, as another weak frontal boundary approaches from the NW,
before settling into the area past mid week. A somewhat NW flow
regime remaining in place over much of the region will also allow
weak upper disturbances to again traverse across the central TN
Valley. Overall temps look to remain near seasonal levels for much
of the work week, with highs in the upper 80s/lower 90s and lows
in the lower 70s/near 70F.

(18Z TAFS)
Issued at 1140 AM CDT Fri Jul 8 2022
A few shra/tsra are beginning to develop south of the KHSV
terminal. Expect this activity to gradually increase in coverage
heading into the afternoon hrs this Fri. Confidence in timing of
any of this activity affecting one of the two main airports is
uncertain and a VCTS group has been maintained for this afternoon.
AMDs though may be needed if any of this convective activity nears
an airfield. Otherwise, mid/high clouds should maintain VFR conds
into the early morning period Sat. A PROB30 group was added late
in the forecast as a weak front approaches from the north.
