.KEY MESSAGES...

- No rain expected across the region today as drier air in the mid
levels will prevent storm development.

- Scattered showers and thunderstorms return this weekend as
moisture pools ahead of a cold front that will push through the
region early Sunday.

- Slightly below normal temperatures and noticeably drier air is
  expected in the wake of the front early next week.

.SHORT TERM...
(Today through Sunday night)
Issued at 1140 AM CDT Fri Sep 5 2025

Dry mid level air continues to stream into the region
on northwesterly flow aloft which will prevent any convection from
developing this afternoon. Unfortunately, southerly flow at the
surface and in the low levels will keep afternoon dewpoints in the
mid 70s making it feel more uncomfortable compared to recent days.
Heat indices will range from 100-105 this afternoon.

Mid level moisture will begin to pool along the gulf coast Saturday
ahead of an upper level trof and frontal boundary. The increasing
moisture will combine with diurnal heating to produce scattered
showers and thunderstorms Saturday afternoon. The increased cloud
cover and storm coverage will limit afternoon highs to around 90.
The aforementioned frontal boundary will push through the area
Sunday morning with a few showers or thunderstorms possibly
developing in its vicinity, but this will not be the kind of sharp
front that creates a qlcs. Winds will turn northerly behind the
front with some dry air beginning to advect into the region.
However, the biggest drops in dewpoint are not expected until Sunday
evening into Sunday night.

.LONG TERM...
(Monday through Friday)
Issued at 1140 AM CDT Fri Sep 5 2025

Significantly drier and slightly cooler air will
continue to advect into the region early next week with dewpoints
falling into the 50`s Monday and Tuesday. This will allow overnight
lows to come down as well. Tuesday morning will be the coolest with
lows around 60 degrees across central Louisiana and interior
Southeast Texas and mid 60s closer to the coast. Afternoon highs
will still climb to near 90, but the drier air will make those temps
more comfortable. The drier air will remain in place through nearly
all of next week both at the surface and aloft. As a result, no
precipitation is expected inland from Sunday through the end of next
week.

.AVIATION...
(18Z TAFS)
Issued at 1215 PM CDT Fri Sep 5 2025

VFR conditions will prevail through the afternoon with SCT to BKN
fair weather CU streaming across the region. No precipitation is
expected at any of the terminals today. Some light, patchy ground
fog will be possible at AEX early Saturday morning. Additionally,
increasing low level moisture and the approach of a frontal
boundary will result in scattered showers moving into the vicinity
of AEX early Saturday morning with activity gradually developing
toward the coastal terminals Saturday afternoon.

Light, southerly winds will prevail this afternoon, becoming
variable overnight before turning out of the north to northeast
Saturday morning.

.MARINE...
Issued at 1140 AM CDT Fri Sep 5 2025

Weak high pressure across the northern Gulf will result in
light southerly winds and low seas. A cold front will move into the
coastal waters Sunday accompanied by scattered showers and
thunderstorms. Offshore winds will develop and increase behind the
front late Sunday into Monday although these will be relatively
short lived and shouldn`t have a significant effect on wave heights
which will remain in the 1-3 feet range. Winds will alternate

.FIRE WEATHER...
Issued at 1140 AM CDT Fri Sep 5 2025

Dry mid level air over the region today will prevent
any shower or thunderstorm development. Light southerly winds will
persist at the surface that will keep minimum afternoon relative
humidity values near or above 50 percent. Moisture will increase on
Saturday ahead of a cold front that will bring a chance for showers
and thunderstorms. The front will push through the area Sunday
turning winds out of the north to northeast through much of next
week.
