.KEY MESSAGES...

- Dry air moving in overhead will limit rainfall potential today and
Sunday. Best chances for light rainfall will be Lower Acadiana.

- High pressure moving east of the region brings moisture and warmth
back to the region into Sunday before a sharp cold front moves
through into Monday.

- Dry and cool conditions expected through the midweek as a
  stronger high pressure area and cool/dry airmass moves into the
  region.

.SHORT TERM...
(Today through Monday night)
Issued at 1200 AM CST Sat Dec 6 2025

Analysis indicates sfc high is located just over cenMS with frontal
boundary now fully clear of Louisiana. It was a very cool day today.
As such, dry air is leaking in overhead (see improvements to PWATs
from 12 and 00z RAOBs), but with surface influence largely
characterized as deeply cool and moist, cloud cover is going
nowhere fast.

Upper trof remains in its position, oriented southwest to northeast
from the Baja Peninsula to Minnesota, with jet influence
overspreading everywhere east of its axis. Over the following days,
this trof begins slowly edging east. Surface troughiness begins to
form and the jet maxima descends towards the surface. This will
throw a few more drizzly, piddly showers over portions of the area
today and perhaps Sunday due to right entrance region passing
overhead. Within any showers that develop, not anticipating any
acute rain banding as the airmass continues losing that deep
moisture supportive of very efficient rainfall.

Sfc high shifts off to the east today, goaded on by aforementioned
troughiness. This will result in quick return flow and airmass
modification today and Sunday. As a result, much warmer, near
normal, temps are anticipated today with temps in the 70s Sunday.

Upper patterns become more meridional into the start of next work
week, signaling the progression of the weather pattern. A sharp cold
front will move through the region late Sunday/early Monday bringing
about a ROLLERCOASTER of temperatures no one bought a ticket for.
Highs in the 70s Sunday will give way to 50s by Monday with brisk
offshore winds and dry conditions.

.LONG TERM...
(Tuesday through Saturday)
Issued at 1200 AM CST Sat Dec 6 2025

The progressive pattern swiftly moves things along by Tuesday. High
pressure slides quickly east of the region bringing about return
Gulf flow. Combined with ridging (rising heights) developing
overhead, very warm, above normal, temps and humid conditions will
develop to the end of the work week.

.AVIATION...
(06Z TAFS)
Issued at 1200 AM CST Sat Dec 6 2025

Very light showers may impact all terminals overnight, but best
chances are at ARA and LFT, the furthest terminals from high
pressure moving north of the region.

Periods of light rain will be possible today once again along and
south of I-10 with low CIGs to match. However, as dry air leaks in
overhead, cloud conditions should be improving throughout the
period. Think 900 to 1500 feet rather than 500 feet.

Winds shift to the south behind passing high to the east of the
region today. This return of moisture and calming conditions should
result in crashing ceilings and fog late in the period.

11/Calhoun

.MARINE...
Issued at 1200 AM CST Sat Dec 6 2025

Offshore flow should again exacerbate low tide cycles today and low
water conditions are expected on Sabine and Calcasieu Bays during
daytime hours. Thus, a Low Water Advisory has been issued until 6 PM
today.

Showery rainfall can be expected until late Sunday/early Monday when
a sharp cold front moves through. Very strong offshore winds will
quickly develop Monday morning and a Small Craft Advisory will be
needed.

&&

.FIRE WEATHER...
Issued at 1200 AM CST Sat Dec 6 2025

High pressure moves off to the east today allowing return flow to
resume late in the day. This will bring about much warmer and more
humid conditions today and Sunday before a sharp cold front moves
through late Sunday/Monday.

Early next week dry air will reduce the chance of rain to zero with
gusty north winds and minimum RH values in the 40 to 50 percent
range through the midweek.
