Area Forecast Discussion
National Weather Service Lake Charles LA
343 PM CDT Fri Oct 15 2021

.SHORT TERM [Tonight through Sunday]...

Much advertised CDFNT currently stretches NE to SW across eastern
and southern TX, and is very near College Station. Pre-frontal
convergent bands are yielding scattered showers and an isolated
thunderstorm or two, with convection having a similar character
along the front itself. Veered winds ahead of the front and
limited upper level support are resulting in relatively weak
lift, so expect convection to remain largely status quo as the
front pushes through the area tonight. Boundary is expected to
enter Tyler County around 7 PM give or take, and is forecast to
have cleared St. Mary Parish by 3 AM if not sooner. Brisk and
gusty north winds will follow the frontal passage, along with an
intrusion of much cooler and drier air, with lows SAT morning in
the mid 50s NW to the lower/mid 60s SE.

North winds will remain elevated into SAT, with latest short range
guidance flirting with wind advisory conditions, especially along
and south of the I-10 corridor. Will hold off for now and let the
next couple of shifts further evaluate. Amid ongoing CAA and
despite ample sun, temperatures SAT afternoon will struggle to
reach the mid 70s. Winds will subside SAT night as high pressure
at the SFC and aloft settles into TX, though they are not expected
to be completely calm. Still, with the bone dry airmass in place
(PWATs progged to be near the minimum moving average for this time
of year) underneath a clear sky, good radiational cooling is
expected, and lows SUN morning are forecast to be the coolest of
this forecast period and the Fall season thus far, ranging from
the mid to upper 40s north to around 50 along the I-10 corridor.

Quiet and cool weather will continue on SUN as the high pressure
to the west slides east into the region, with highs again perhaps
reaching the middle 70s. Some increase in mainly mid/high level
cloud cover is expected SUN afternoon and night ahead of an
approaching shortwave trof, which along with some slight airmass
moderation, will help hold temperatures SUN night/MON morning a
little higher, ranging from the upper 40s to lower 50s.

.LONG TERM [Monday through Saturday]...

At the start of the long term period the forecast area will remain
under the influence of high pressure both at the surface and aloft.
Aloft, ridging extending from the Northern Plains to the Gulf Coast
will remain in control through the mid-week, while gradually sliding
east. At the surface, a high pressure ridge over the SE US will
gradually slide eastward through the mid-week as well. The slow
departure of the surface high will result in a return of east to
southeasterly winds by Tuesday as well as a slow warming trend. Highs
in the mid 70s on Monday will rebound back into the low to mid 80s
by Wednesday. East to southeasterly flow will be slow to bring
moisture back into the region, so rain chances will remain near zero
through the first half of the week, while humidity will be slow to
return as well.

Moving into the second half of the week, the pattern begins to
change as the long term models continue to signal to another frontal
passage. A weak upper level low will move across the Plains and into
the Midwest late Wednesday into Thursday, which should send a cold
front through the CWA sometime around the Thursday/early Friday
timeframe. Biggest question at this point is the strength of this
front, as the models have not been in agreement this far out.
Currently, it doesn't look like this front will be as strong as the
one moving through tonight, but it should still be able to bring an
end to next week's warming trend.

.MARINE...
A light onshore flow will continue through early evening, with
winds veering to the north and becoming strong and gusty behind a
cold front expected to push through the coastal waters tonight.
Have hoisted a gale warning for the Gulf waters and a SCY for the
coastal lakes and bays from mid evening tonight through noon
Saturday, but additional hazards will likely be needed as north
winds will remain elevated and gusty through the afternoon,
before starting to subside tomorrow night as high pressure settles
into the region. Winds are expected to gradually shift to the
southeast by midweek as the high moves off to the east.
