.SHORT TERM...
(Tonight through Tuesday night)
Issued at 1225 PM CDT Sun Sep 7 2025
Surface analysis shows a cold front draped along the northern Gulf
Coast, while high pressure is over the Midwest/MS Valley region.
Behind the front, a very pleasant start to our Sunday is ongoing
across SE TX and south LA, with temperature currently in the mid to
upper 70s. While cooler air has definitely arrived, drier air is
still on its way. Dewpoints currently sit in the mid to upper 60s,
while RH values range from the mid 60s to upper 70s across the CWA
at this time. Still, a very nice afternoon is on the way as cloud
cover has largely cleared out overhead, which should allow
temperatures to warm into the mid 80s.
Tonight, drier air finally arrives with dewpoints falling into the
low to mid 50s by sunrise. This should allow overnight lows to cool
into the upper 50s to mid 60s. Tomorrow, clear skies along with
cooler and drier air will make it feel like a very pleasant early
fall day. After a full day of dry air advection, Mon night/Tues
morning brings the coldest lows of the forecast period, with NBM
showing mid/upper 50s across our northern zones, with lows in the
low 60s elsewhere. Moisture begins to return just slightly on
Tuesday, particularly across Acadiana, as weak troughing overhead
starts to slowly dissipate. Still, should be a rather nice day with
no rain and sunny skies on tap. Highs warm into the mid 80s to near
90, while overnight lows fall into the mid 60s to low 70s.

.LONG TERM...
(Wednesday through next Saturday)
Issued at 1225 PM CDT Sun Sep 7 2025
Enjoy this taste of fall while its here, because the second half of
the week brings a warming trend along with a slow return of moisture
as troughing overhead dissipates and gets replaced by ridging over
the Plains. While moisture returns aloft, a series of surface highs
moving across the Great Lakes/Appalachia will keep a NE to E flow in
place at the surface, which will help to slow moisture return to an
extent, especially for inland areas. Along and south of I-10,
dewpoints will largely range from the upper 60s to low 70s
throughout the second half of the week, while further inland some
dips into the mid 60s are expected. Temperature wise, highs return
to the low to mid 90s on Wednesday and remain there through the end
of the period, while overnight lows generally range from the upper
60s to low 70s. On the bright side, rain chances remain near zero
through the weekend.

.AVIATION...
(18Z TAFS)
Issued at 1225 PM CDT Sun Sep 7 2025
BKN/OVC cloud deck has cleared out over the last few hours, except
at BPT. Cloud cover should largely clear out of BPT through the
afternoon however, some SCT cloud cover may linger as moisture
remains elevated over to our west. Otherwise, northeasterly flow
near 5-10 kts and clear skies are expected area-wide throughout
the forecast period.
&&
.MARINE...
Issued at 1225 PM CDT Sun Sep 7 2025
A modest offshore flow will remain in place through Wednesday
behind the front that is currently in the coastal waters. Winds
and seas will increase a bit this evening/tonight as high pressure
builds down from the Midwest and briefly tightens the pressure
gradient overhead. Small craft should exercise caution through
this period. By the mid week winds/gusts will ease and gain more
easterly components.
&&
.FIRE WEATHER...
Issued at 1221 PM CDT Sun Sep 7 2025
Moisture will continue to decrease today, and more so tonight, behind
a cold front that is currently offshore. Afternoon minimum
relative humidity will generally range 45-55 percent today and
further decreasing toward 30-45% on Monday. Moisture will slowly
return through the mid/late week, mainly along and south of I-10
however, dry conditions continue with little to no rainfall
expected through the end of the forecast period.
