.NEAR TERM...
(Tonight)
Issued at 800 PM CDT Sun Jul 13 2025

Clusters of thunderstorms east of I-65 will gradually diminish
with time after sunset. Temperatures have cooled into the 70s
where the rain has fallen. These will also be areas that have a
tendency for fog to develop overnight. Will monitor those trends
late this evening, but for now, expect patchy to areas of fog once
the sky clears.

.SHORT TERM...
(Monday through Wednesday Night)
Issued at 800 PM CDT Sun Jul 13 2025

The models continue to forecast the mid and upper level high
center over the central Gulf Coast area will narrow and lift just
a bit further north through Tuesday as a wave along the trough
from southern MO into southwest TX lifts northeast into the mid MS
Valley and eastern Corn Belt Tuesday and Wednesday. The very
warm, moist and unstable environment will remain present during
this period over the TN valley, with mainly afternoon and evening
thunderstorm chances continuing. On Wednesday, the trough moving
west across the FL peninsula will enter the northeastern Gulf,
with a northward trough/convergence axis moving northwest through
GA into eastern AL. This may enhance the thunderstorm chances in
our eastern counties on Wednesday afternoon and evening. During
this time, gusty outflow winds and frequent lightning will be the
main storm hazards. Temperatures will nearly be a persistence
forecast with highs in the lower to perhaps middle 90s dependent
on afternoon thunderstorms and outflows, with lows in the upper
60s to lower 70s tonight, and lower to middle 70s the next several
nights.

.LONG TERM...
(Thursday through Sunday)
Issued at 800 PM CDT Sun Jul 13 2025

The models forecast the track of the Gulf Trough/low into the
lower MS valley from Thursday into Friday, while a weak west-
east ridge axis remains at 5h from OK through the TN valley. This
will keep a similar weather forecast late this week into next
weekend. By next weekend, MCS (ridge riders) may trickle into
KY and TN as well. So expect more diurnally driven convection,
along with watching potential outflow boundaries from any MCS that
does approach our area from the north/northwest. High temperatures
will remain very persistent in the upper 80s to lower 90s, with
lows mainly in the lower 70s during this period.

(00Z TAFS)
Issued at 537 PM CDT Sun Jul 13 2025

Small clusters of SHRA and TSRA will dissipate quickly early this
evening. VFR conditions are expected for most of the night, until
patchy BR and FG develops. Confidence is too low to include at
either KHSV or KMSL at this time, but amendments may be needed as
trends dictate. Isolated to scattered TSRA are again expected
after 18Z/14, but again, will leave out until confidence increases
and timing at KHSV and KMSL are better defined.
