Latest surface analysis showed a deep 988mb low over southeast
nebraska with a strong to moderate flow across the plains and mid
mississippi valley. A light southeast flow was noted across
southeast louisiana and south mississippi. At times...vad wind
profile revealed southeast winds 30 knots just off the surface at
1kft. With the deep low over the plains...heating and strong warm air
advection...a good deal of these winds will mixed down to the
surface by 15z today and persist through 22z. A few areas may
experience winds up to 15 to 25 mph and gusty across north and
northwest zones...but do not expect sustained 25 mph today. Will
mention winds in hwo but no wind advisory for now. Regional radar
revealed isolated showers south of new orleans and extreme
southwest louisiana. Upper air analysis showed a west to southwest
flow over the plains and mississippi valley and main trough over
the rockies with several waves. The first wave will eject east
across the central plains today through the great lakes by monday
morning. As a result...the surface low will track northeast to the
great lakes dragging a boundary to just northwest of the forecast
area monday afternoon. Mid layer moisture pooling along the associated
trough axis will create a marginally unstable atm across the
northwest zones. Will insert convection over btr monday afternoon.
System will become stretched and surface boundary is expected to
drift north and dissipate going into tuesday. Tuesday through
thursday...the central gulf coast region will remain under a dirty
southwest flow. Gfs and ecmwf want to bring a frontal boundary
through the area next weekend. While both show the trough
position changing from west to the east...flow remains
progressive...westerly of the gulf region and cold air mass
pushing through the forecast area may not occur for day 6 and day
7...will remain slightly above mex numbers for now.

.aviation...
Water vapor imagery this morning clearly showing abundant moisture
fetch from the pacific ocean. Good low level moisture could bring
about mvfr cigs early in the morning with low clouds lifting some
during the day. Mid level and high clouds are expected to persist
through the day. Strong southeast flow is expected today resulting
in gusts near 25 kts by around noon. Gusts will die down after
sunset but winds will still stay elevated during the evening.

.marine...
Surface pressure gradient will continue to tighten today as lower
pressure from the nw approaches and high pressure slowly drifts
eastward. Winds will increase as the cold front approaches the area.
Far off shore may see gusts up to 30 kts but 15 to 25 will be norm.
For this reason...will keep small craft advisory through mon 12z.
Small craft exercise caution headliner issued for lakes pontchartrain
and maurepas as southeast winds of 15 to 20 kts are likely...but
should drop off after sunset. The aforementioned front will stall
over southern louisiana and mississippi on monday night before
moving north as a warm front on tuesday.

Early this morning there was a surface low over the western great
lakes with a cold front extending into central texas. Aloft there
was a trough over the northern plains/upper mississippi
valley...with southwest flow over the gulf coast. The trough will
stay well north of our area as it progresses to the east...so the
surface cold front will have a hard time making it into our area.
The front looks to move into portions of east-central louisiana
and south mississippi later today and be retreating north on
tuesday. Temps return to above average by wednesday...with
lingering slight chances for precip the following few days. The
next system is expected to develop in the desert southwest and
move rapidly into eastern great lakes by friday morning...with the
cold front approaching the lower mississippi valley and stalling
near/north of our area. Again the associated upper trough will
remain north of our area...limiting the southward progression of
the front. In addition...with the relatively warm/moist air
moving across the coastal waters...fog and stratus will pose a
threat each night/early morning. 25

.aviation...
Light showers have been progressing northward across the area with
the more prevalent activity near gpt. Low cigs and vis will be the
main concern this morning as areas of fog impact the
terminals...mainly gpt and mcb. Btr and msy shouldn/t have to deal
with much more than vis around 3sm. Lifr cloud decks will accompany
showers and likely linger at gpt and mcb through the morning. Low to
mid level clouds will persist throughout the day with generally mvfr
conditions at all sites. Fog will likely return late tonight.

Meffer

.marine...
Latest msas graphic has indicated that the surface pressure gradient
has begun to relax this morning. Winds have been gradually coming
down offshore and sea heights should follow suit. Only concern is
buoy 040 which still has seas around 10 feet...but still expecting
to drop below small craft criteria around sunrise. A cold front will
make its way into southeast la today but shouldn/t reach the gulf
waters before stalling. It proximity to the coast should result in
relatively light winds in the gulf waters. South winds will pick
back up as the front lifts back north on tuesday. 3 to 5 foot seas
will persist through the week. The next cold front late this week
may bring the return of small craft conditions. Will have to
continue to monitor this possibility.

The primary concern this morning was the extent to which the cold
front and associated air mass had made it through our pcwa. The
models do indicate the frontal position okay...from southeastern
mississippi through new orleans to the mouth of the atchafalaya.
Unfortunately the front is very shallow and the mos guidance has
not picked up on the temperature falls behind the front. Temps
were in the mid 40s at btr and mcb at 3am...going down to the mid
to upper 30s toward hez and aex. Thus we will be undercutting
guidance for temps today and tonight...having highs from the upper
40s in the extreme northwest portion of our pcwa...to the mid 5os
near btr and mcb...mid 60s in extreme southeast louisiana...and
near 70 around coastal mississippi. This significantly undercuts
guidance behind the front...and it is possible that these temps
may still be a little too high at btr and mcb. Tonights lows will
hinge on the retreat of the front to the north/northwest. The next
system is expected to move from the desert southwest into the
plains states on thursday...and drop a cold front to near our area
by friday afternoon. However...the upper-level support will be
well to the north and the front will have a hard time progressing
into our pcwa. Over the weekend an upper trough will move across
the plains states into the ohio valley...and help push the frontal
boundary through our area. 25

.aviation...
Showers continue to move across southeast louisiana and southern
mississippi. Most of the activity is east of btr and mcb...leaving
msy and gpt to see periods of light rain. Pops will gradually
diminish through the day. Areas of moderate fog will persist through
the rest of early morning hours. Expect vis to drop as low as 1/4
mile with vlifr to lifr cigs. Conditions will improve some today
reaching low end mvfr cigs by afternoon. Similar br and fg problems
will return again tonight. Winds are expected to be light and
variable at btr and mcb today as a frontal boundary transitions
from stalled front to warm front and lifts north. With msy and gpt
south of this boundary...southerly winds will increase this
afternoon but should remain below 10 kts.

Meffer

.marine...
Moderate fog looks to be the only significant weather expected to
impact the coastal waters and tidal lakes this morning.
Visibilities may drop to 1/4 to 1/2 mile at times but should
improve after sunrise. Frontal boundary looks to have stopped its
forward progression...so winds will stay sewd. Weak surface
pressure pattern in place will keep southerly winds on the light
side for the next couple of days. Another round of reduced vis
will impact the near coastal waters and tidal lakes again wed
morning as abundant moisture and light winds as well as cool water
temps will provide a conducive environment for fog development.
Winds should increase late this week as a front passes to the
north of the area and causes the pressure gradient to tighten
bringing outer water seas to the 4 to 5 foot range. A possible
cold front late this weekend could bring small craft conditions to
all coastal waters.

THE FRONTAL BOUNDARY HAS RETREATED NORTHWEST OF A BATON ROUGE-
MCCOMB LINE. THE WARM...MOIST AIR IS EXPECTED TO REMAIN ACROSS THE
AREA INTO THE WEEKEND. THE DENSE FOG SHOULD LIGHTEN LATER THIS
MORNING. FOG IS EXPECTED AGAIN WEDNESDAY NIGHT/THURSDAY
MORNING...BUT IS NOT EXPECTED TO BE QUITE AS DENSE ACROSS THE
ENTIRE AREA. OTHERWISE...LITTLE CHANGE IS EXPECTED THROUGH
SATURDAY.

THE NEXT SYSTEM TO AFFECT OUR AREA WILL MOVE OUT OF THE DESERT
SOUTHWEST FRIDAY NIGHT...WITH THE SURFACE LOW MOVING INTO THE
OHIO/TENNESSEE VALLEY BY SUNDAY MORNING AND COLD FRONT MOVING
THROUGH THE LOWER MISSISSIPPI VALLEY LATER SUNDAY. THE UPPER-LEVEL
LOW ASSOCIATED WITH THIS SYSTEM IS EXPECTED TO MOVE FROM THE
NORTHERN PLAINS INTO THE GREAT LAKES...THEREFORE MOST OF THE
ENERGY WILL STAY TO THE NORTH OF OUR AREA. INSTABILITY ALSO LOOKS
TO BE LIMITED...DECREASING THE CHANCE FOR THUNDERSTORMS. 25

.AVIATION...
WIDESPREAD DENSE FOG CONTINUES TO IMPACT ALL SITES THIS MORNING AS
LIGHT WINDS COMBINED WITH ABUNDANT LOW LEVEL MOISTURE PROVIDE PRIME
CONDITIONS FOR FOG DEVELOPMENT. CIGS AND VIS HAVE BEEN BOUNCING BACK
AND FORTH BETWEEN VLIFR TO LIFR WITH MSY AND MCB HAVING THE MOST
DENSE FOG. LATEST GUIDANCE SUGGESTS CONDITIONS WILL BE SLOW TO
IMPROVE THIS MORNING...POSSIBLY NOT REACHING MVFR/VFR UNTIL NOON.
SOUTH WINDS TODAY WILL BE GENERALLY LIGHT AT AROUND 5 KTS. SCT TO
BKN LOW DECK WILL PERSIST THROUGH THE AFTERNOON AND AND EVENING
HOURS. AREAS OF LIGHT TO MODERATE FOG WILL BE POSSIBLE THURS MORN
BUT NOT EXPECTING TO BE QUITE AS DENSE AS THIS MORNING.

MEFFER

.MARINE...
WIDESPREAD DENSE FOG WILL IMPACT THE NEAR WATERS THROUGH MUCH OF
THIS MORNING. CONDITIONS WILL STRUGGLE TO IMPROVE SIGNIFICANTLY
UNTIL AROUND NOON. SURFACE HIGH PRESSURE WILL REMAIN ANCHORED IN THE
SOUTHEASTERN CONUS THROUGH THIS WEEK. WINDS WILL STILL BE RELATIVELY
LIGHT AT NEAR 10 KTS TODAY KEEPING SEAS AT AROUND 2 FEET IN OUT
WATERS AND LESS ALONG THE COAST TODAY. EXPECT SOUTH TO SOUTHEAST
WINDS 10-15 KTS AND 2-4 FOOT SEAS FOR THE REMAINDER OF THE WEEK. A
COLD FRONT WILL PUSH THROUGH THE AREA THIS WEEKEND. UNCERTAINTY
STILL SOMEWHAT OF A PROBLEM AS MODELS KEEP CHANGING FROPA FROM RUN
TO RUN. SMALL CRAFT CONDITIONS APPEAR TO BE LIKELY BEHIND THIS
BOUNDARY.

The frontal boundary continues to linger to the northwest of a
baton rouge-mccomb line early this morning. Warm...moist marine
air continues to move onshore. This will keep the sea fog in the
area again this morning. Friday morning will see stronger boundary
layer winds as a low pressure system moves from the central plains
into the ohio valley. This added mixing should help to mitigate
the fog a little bit...possibly keeping the fog just above
advisory criteria. Otherwise...this front is not expected to push
through our area...giving only a small chance for rain in the
northern portions on friday. The next system will be more
vigorous. The surface low is expected to move from the central
plains on saturday into the eastern great lakes by sunday
morning...dragging a cold front into the lower mississippi valley.
The gfs may be a bit too fast pushing the front through our area
on sunday morning since the better push will be to the west where
the ridge will be digging and the east closer to the surface low.
Behind this front the temps are expected to drop into the 30s
across most of the area monday morning...with small craft
advisories likely. 25

.aviation...
/06z taf issuance/
dense fog and low ceilings are currently affecting all taf sites.
Lifr conditions are expected to last through the remainder of the
night and into thursday morning as a warm and moist airmass
continues to slide over cooler waters along the coast and in the
tidal lakes. Fog is expected to begin lifting after 13z as daytime
heating begins to kick in. By thursday afternoon...the low level
inversion should be completely eroded...and stronger boundary layer
winds are expected to develop. These conditions should allow for
mvfr or vfr conditions after 18z. 95/dm

.short term...
One more unseasonably warm day is in store before a canadian cold
front sweeps through the area overnight. Cold front is currently
moving south-southeast at 28 mph across the high plains with the
leading edge in central kansas. These arctic type fronts of late
have been undercutting strong southwesterly flow aloft and this
one is no different. Nohrsc snow cover image indicates a solid
snow cover from canadian border to the southern kansas state
line...so air mass modification of the cold air will be minimal to
non-existent until reaching the gulf coast sunday morning. Went
higher than guidance today by a few degrees due in part to
compressional heating and starting from warm overnight
temperatures...closer to persistence of friday`s highs. Went
pretty close to gfs guidance for tonight which best matches
expected frontal passage timing...off the coast by 12z. Cold air
advection during the day sunday will only muster about a 5 degree
spread in min/max...followed by a freeze sunday night away from
tidal lakes and coastal influences. Will also maintain pre-frontal
showers tonight and early sunday but drying things out before
noon. 24

.long term...
Modifying arctic airmass moves east monday with onshore baroclinic
return likely to onset monday night. This will allow overnight
lows to only drop a couple of degrees from daytime highs and
possibly warm overnight due to nocturnal warm air advection. Gfs
shows a pacific type cold front moving across the area wednesday
evening with a swath of rain that may hang up across the region
christmas day. Will show a 30 percent chance of showers thursday
but with unseasonably mild temperatures. Another cold front
approaches the area next weekend. 24

&&

.aviation...
/preliminary 12z taf issuance/
low clouds are the reason for mvfr and ifr condtions at all
terminals this morning. As winds increase through 3kft and very
weak disturbances move through...these conditions should persist.
As the inversion stregnthens a bit this morning...there will
remain a possibility for the low level ceilings to drop and
quickly cause fog to set in once again mainly around sunrise.
Ceiling and vis conditions will improve to mvfr around 15z today.

&&

.marine...
Dense fog still to be a problem through 9am this morning. Once the
current dense fog advisory expires...we should not see problems with
fog wed night into thu.

A strong cold front is expected to move through the coastal waters
sunday morning. Winds and seas are expected to reach small craft
conditions with gusts to gale force as a strong ridge of high
pressure builds into the area sunday into sunday night. Return flow
around the high will bring a lengthy period of southeast winds
around 15 to 20 knots for tuesday through midweek.
