.MESOSCALE UPDATE...
Issued at 704 PM CDT Mon Sep 8 2025

Updated the forecast elements through tomorrow afternoon, but no
major adjustments were made. High pressure across the eastern
CONUS is still the prevailing influence, but an upper-level
disturbance interacting with an easterly surface wave will bring
a slight chance for showers and thunderstorms to the Gulf Coast
areas tomorrow. /NF/

.DISCUSSION...
Issued at 1244 PM CDT Mon Sep 8 2025

Tonight-Tuesday:

Clear skies with comfortable temperatures are expected over the next
couple of days. Trough pattern continues to move eastward, limiting
rain chances across majority of the area and keeping northerly winds
across the area. SE MS could see an isolated chance (15-20%) for
rain Tuesday afternoon as a weak disturbance moving over the area.
These rain chances will decrease shortly after sunset. Highs are
expected to reach the mid/upper 80s with lows in the upper 50s to
lower 60s.

Wednesday-next Sunday:

Persistent clear conditions are expected through the rest of the
period. Ridging pattern will migrate towards the southeast CONUS,
causing high temperatures to start in the upper 80s/near 90s,
reaching the mid/upper 90s by the end of the forecast period.
Overnight lows are expected to range in the 70s. Little (less than
5%) to no rain chances are expected for the remainder of the
period. /SW/

.AVIATION...
(06Z TAFS)
Issued at 1226 AM CDT Tue Sep 9 2025

VFR flight categories will overall prevail at area TAF sites over
the next 24 hours. Some patchy shallow ground fog can`t be ruled
out at sites towards day break. This could result in temporary
drops in visibilities, at sites where observed, to MVFR/IFR status
for a brief period of time. Such fog will quickly erode after
sunrise. A weak wave along the gulf coast could yield an isolated
shower or storm at namely KHBG or KPIB this afternoon, but overall
coverage is currently too low to include in this 06Z TAF package.
Winds overnight will be light from the northeast to calm. Winds
will increase to between 5-8 knots from the east southeast by late
morning. /19/
