Area Forecast Discussion
National Weather Service Lake Charles LA
1152 AM CST Wed Dec 11 2019

.DISCUSSION...
For 18z TAF issuance.

&&

.AVIATION...
A pretty straight forward forecast this morning, especially for
the first 18-20 hours as forecast soundings/time-height sections
indicate a fairly dry atmosphere...main issue through this
afternoon remains the elevated nrly flow with plentiful gusts
above 20 knots at the srn terminals. Thereafter, will begin to
see ceilings develop (albeit VFR at this time) as low-level flow
turns a bit more srly with high pressure moving east of the area
and mid-level flow also gains a srly component with the approach
of the next wave aloft. Some guidance is indicating the potential
for MVFR cigs late, especially for the Acadiana terminals, but
have kept them above 3K feet for now.

.PREV DISCUSSION... /issued 602 AM CST Wed Dec 11 2019/

AVIATION...All rains have now exited the forecast area. Gusty
northeast winds will continue into the afternoon before gradually
relaxing late. MVFR stratocu blankets the region but will be
clearing through the morning.

PREV DISCUSSION... /issued 542 AM CST Wed Dec 11 2019/

DISCUSSION...
The cold front that moved through yesterday morning has moved into
the central gulf this morning. Winds remain elevated across the
region as cold air advection continues to filter in from the
north. Yesterday at this time Lake Charles was reporting
temperatures near 71 degrees... this morning we are hovering in
the mid 40s. Alexandria currently is reporting 39 degrees.

Stlt images shows a low deck of clouds across the central and
southern tier of the state... across the northern tier... skies
have cleared and winds have become light. Clouds and the winds
have managed to hold up the morning temps into the mid 40s for
this region... while Ruston in northern Louisiana is reporting 30
degrees. Clouds will continue to erode with the southern tier of
the state clearing during the late morning hours.

Afternoon highs even with clearing skies will struggle to reach
the upper 50s on northerly winds.

The surface low and associated cold front in the gulf is expected
to lift back northward during the day tomorrow with clouds
returning and the chances for rains spreading back into south
central Louisiana. The area of high pressure to our north is
expected to move rapidly to the northeast and looks to be in the
New England states by sunrise on Thursday... but the high ridge
back down into Texas and Louisiana.

Friday afternoon and into the weekend looking at mostly clear
with morning lows in the 50s along the I-10 corridor and afternoon
highs into the 70s. Long range has another system moving through
on Monday into Tuesday.

Marine...Winds in the coastal waters are ranging from 20 to 30
knots with higher gusts... but winds have been dropping and the
Gale warning will be replaced by a Small Craft Advisory that will
go through midnight.
