.SHORT TERM...
(Tonight through Wednesday night)
Issued at 1159 PM CST Sun Dec 7 2025

The main prefrontal boundary has moved through and the bulk of
showers have been swept east of the Atchafalaya Basin. There are
some very low level thin post-wind shift showers streaming in from
the northwest, but these are very few and far between. Low clouds
and moisture will also continue streaming down into southeast Texas
and Louisiana keeping low clouds, thin drizzles and intermittent fog
in the forecast through morning.

Much cooler and drier air will fully filter into the area on strong
north winds through the morning hours. This will wash out all
remaining surface clouds and moisture into the early afternoon.

High pressure swiftly dives into the southeast US Tuesday with very
localized ridging setting up right overtop the forecast area. This
will result in clear, calm conditions and a mildly moderating
airmass into Tuesday. Sfc high shifts east on Wednesday allowing for
return flow to set up and temps to rise back into the 70s once again
by the midweek. Moisture returns as well, bringing back humid
conditions and cloud cover.

.LONG TERM...
(Thursday through next Sunday)
Issued at 1159 PM CST Sun Dec 7 2025

Guidance has largely settled into a single big picture scenario for
the longterm: sfc high pressure remains to the east of the region
through the end of the work week. Its influence will keep the
airmass moderated and in the lower 70s to finish the work week. This
would be beautiful weather if dewpoints wouldn`t settle into the 50s
and 60s as well.

The end of the forecast period does look rather chilly once again
with a strong progressive upper level pattern bringing another
robust cold front into the region to end the period.

.AVIATION...
(06Z TAFS)
Issued at 1159 PM CST Sun Dec 7 2025

Showery precipitation is exiting the region. However, dry air and
high pressure are lingering behind the main front. This will keep
very widely scattered drizzly showers, occasional low VIS and low
ceilings in the forecast through the early morning. Conditions
are set to start improving from mid morning through early
afternoon, from north to south, as high pressure slides south and
dry air takes over.

Although the improving airmass is hanging back, northerly winds are
still set to develop and strengthen from now until morning. Expect
strong northerly winds to prevail during daytime hours before
relaxing after 00z.

.MARINE...
Issued at 1159 PM CST Sun Dec 7 2025

Strong offshore winds sustained at 20 to 25 knots with gusts to
30 knots will persist until late Monday as the post-front gradient
relaxes. Winds quickly fall overnight into Tuesday with high
pressure developing overhead. This high moves east quickly into
Wednesday with a return to onshore flow

&&

.FIRE WEATHER...
Issued at 1159 PM CST Sun Dec 7 2025

Much cooler and drier conditions will develop with daytime
minimum RH values in the 50s and then 40s anticipated Monday and
Tuesday, respectively. Fire weather concerns are not overly
anticipated due to the improvement in ground moisture from recent
rains. Breezy northerly winds will develop overnight and will
prevail throughout the day before falling with sundown. High
pressure quickly develops and moves over the region on Tuesday
before settling to the east Wednesday with a return of gulf
moisture will begin its return late Tuesday into Wednesday as
well.
