.SHORT TERM...
(Rest of today through Saturday)
Issued at 1125 AM CDT Thu Aug 6 2026

Yesterday's storms were focused along a low-level instability
gradient from Clay and Macon Counties down to Lawrence County.
Very heavy downpours created some localized spots of flash
flooding. We do not expect as much coverage today, but where
scattered storms occur, the threat for very heavy rainfall and
localized flooding will continue. A few spots could see 2 to 3
inches of rain while most of Middle Tennessee will get through the
day rain-free. Otherwise, typical August heat and humidity will
be in place with heat index values touching 100 for many areas
west of the Plateau.

The cutoff upper low that has lingered over our eastern counties
the past few days will continue to weaken today and eventually get
absorbed into prevailing winds north of our area Friday into
Saturday. Still, a band of deep moisture will linger as an impulse
comes our way from the west northwest. This will keep the
scattered shower and storm pattern going with lowest coverage west
and greater coverage east, especially Plateau. Probabilities for
rain and storms will peak Saturday, ranging from 30 percent west
to nearly 70 percent along the PLateau.

There will be enough instability for a few "strong" storms with
gusty winds of 40 or 50 mph, but we are not looking for widespread
or organized severe wx. The main concern will be heavy rain
leading to local flash flooding, like we saw in Lawrenceburg and
a few other spots yesterday when 2 to 3 inches of rain fell in a
short period.

The deep convection will continue to be mostly diurnal, with
showers and storms mostly ending with sunset. This will set the
stage for areas of late night fog, especially where rain falls.

&&

.LONG TERM...
(Saturday night through next Thursday)
Issued at 1125 AM CDT Thu Aug 6 2026

Strong high pressure systems will be centered off to our
southeast and out to our west. We will experience relatively weaker
ridging in between. This means a very warm and humid pattern with
daily chances for showers and storms. It is nearly impossible to
be precise about rain hitting any particular location. Sadly, many
spots will not get much rain at all through the next week while
a few spots get too much. In general, Sunday through Tuesday look
like the days with lowest rain coverage (10 to 30 percent) and
hottest conditions as the 2 high pressure centers bridge together
across the area. The ridge will weaken over our area mid to late
week, allowing daily storm chances to increase (30 to 60 percent).

Most days will bring heat index values over 100 for areas west of
the Plateau. The hottest days, Sunday through Tuesday, could see
heat index values topping 105 for some spots. This will push the
Heat Risk level to 3 out of 4 for many areas and advisories may
be considered.

.AVIATION...
(18Z TAFS)
Issued at 1225 PM CDT Thu Aug 6 2026

VFR to MVFR conditions are expected at all TAF sites this TAF
period. Could see some TSRA this afternoon, but it should be
confined to Plateau sites (CSV/SRB), though we could see a rogue
thunderstorm west of the Plateau. Winds will lessen tonight and
turn to be more southerly, before increasing between 5-10 knots in
the early morning hours and staying that way through the day
Friday.
