Area Forecast Discussion
National Weather Service Lake Charles LA
935 PM CST Wed Dec 28 2016

.DISCUSSION...
Dense fog mainly holding just south of I-10, with intermittent
dense fog or very low ceilings as the case in BPT when the winds
picked up around 10 kts. Believe the winds will diminish ahead of
the front overnight, with the cloud layer lowering to the ground
further inland, producing dense fog along and south of the I-10
corridor. Thus, no changes to the dense fog advisory at this time,
as well as the remainder of the forecast.

DML

&&

.PREV DISCUSSION... /issued 519 PM CST Wed Dec 28 2016/

DISCUSSION...
Dense fog advecting northward from the coast across SE Texas & SW
Louisiana, literally watching the fog bank move northward across
the LCH airport. Thus, had to advance the dense fog advisory a
few hours in time, but made no changes to areal extent of the
advisory. May have to expand the dense fog advisory northward for
the evening update if this fog bank continues to move northward.

DML

AVIATION...
As mentioned above, dense fog advecting northward from the coast
across SE Texas & SW Louisiana which will yield LIFR visibilities
and ceilings for BPT/LCH/LFT/ARA. Then the strong cold front
expected to move through between 10-12z Thursday morning, with
strong northerly winds ~20-22 kts with gusts near or over 30 kts
by 14-15z Thursday.

DML

PREV DISCUSSION... /issued 447 PM CST Wed Dec 28 2016/

DISCUSSION...Another very mild day ongoing. Yesterday evenings
cool front that slipped into the area and produced a few showers
and thunderstorms has rapidly retreated north. Low level moisture
will continue to advect into the area with the potential for yet
another round of dense fog overnight, particularly over the
southern half of the forecast area. Have issued a dense fog
advisory accordingly.

Cold front progged to sweep across the area late tonight and
early Thursday morning. Moisture availability with front will be
limited and carrying no more than chance pops at this time with
feature. Front and sharply drier air following will bring an end
to the persistent fog threat as well as dropping temperatures back
to more seasonal norms. Do expect to see a rapid post-frontal
clearing Thursday but strong cold air advection will limit any
significant warmup through the day.

Friday looking dry with a north to northwest flow through the
column between an exiting east coast trof and a modest plains
ridge. A deep southerly flow then develops for Saturday
accompanied by a low level jet of 40 to 50 knots latching on to
extensive gulf moisture. Mid and upper levels trend southwest
picking up high end Pacific moisture. Bottom line looking at a
near saturated sounding developing through the day with record or
near record precipitable water values. Beginning of the weekend
looking wet. Rain chances then lessen going into the new week as
available moisture gradually diminishes.

MARINE...Dense fog will continue overnight over the near coastal
waters. A strong cold front will advance across the northwest
gulf Thursday morning. This feature will clear any existing fog
and shut down any fog potential for a few days. Strong and gusty
northerlies will follow the boundary and advisories or watches
have been issued.
