Area Forecast Discussion
National Weather Service Lake Charles LA
940 PM CDT Mon Mar 14 2022

.DISCUSSION...
Severe thunderstorm watch 45 was issued earlier this evening for
the interior southeast Texas counties where instability is
forecast to be more substantial than areas closer to the coast. So
far, stronger activity has remained just to the north of the
forecast area with just scattered light to moderate showers
pushing northeast across southeast Texas and southwest Louisiana.

A weak warm front presently analyzed from near Orange, TX to
Jasper will continue to lift northeast across the region through
the late night increasing temperatures and dewpoints. Meanwhile,
the 00Z KLCH RAOB observed a very robust 300 M2/S2 of 0-1km
helicity. The biggest limiting factor for strong to severe storms
will be the limited instability. A few stronger discreet storms
will remain possible within the warm sector over the next few
hours with a squall line expected to push through the region from
approximately 07Z through 13Z. Would not be surprised to see a new
severe thunderstorm watch issued later tonight to cover the
potential for severe wind within this squall line. The grid
package reflecting this was updated earlier this evening and is
already out.

DISCUSSION...
00Z TAFS

AVIATION...

Scattered shower activity is beginning to fire up across the
region this evening, mainly across SE TX at this time. Coverage
will continue to increase as we head into the overnight hours,
ahead of a squall line that will pass through the region overnight
around the 06-11Z time frame. Ahead of this line, scattered
showers and thunderstorms will persist, with some of these storms
potentially becoming severe. As this squall line moves through the
region, heavy downpours, lightning, and reduced VIS can all be
expected. CIGS will mainly be MVFR with the passage of the squall
line, with maybe a brief period of IFR possible. Conditions will
improve behind the squall line tomorrow morning, with clouds
scattering out through the day. Tomorrow afternoon, main concern
will be gusty northwest winds with gusts around 20kts expected.
Otherwise VFR conditions prevail through the day tomorrow.

PREV DISCUSSION... /issued 415 PM CDT Mon Mar 14 2022/

SHORT TERM [Tonight through Wednesday morning]...
Scattered showers fell across southeast Texas and southern
Louisiana today. The southerly winds are pushing a warm front
across southeast Texas and southern Louisiana attm. This will put
the region into the warm sector for tonight into tomorrow ahead
of the front and into a deeper pool for moisture. An upper lvl low
with a vort max swinging down into the region and with moisture
pooling in the warm slot this with support storm development with
the main threat from winds and large hail. An isolated tornado is
also possible ahead of the front. The front will begin to move
through during the early morning hours in southeast Texas and into
southern Louisiana after sunrise on Tuesday. Precip water is
expected to be around 1.40 inches and this will give around 1/2
inch to an inch of rainfall. As we remain on the dry side this is
expected to help the moisture profile for the farmers.

The front looks to exit south-central Louisiana around the noon
hour as rains draw to a close. This front is a Pacific front which
will be different from the recent fronts with temperatures for
morning lows only in the 40s to near 50 and daytime highs in the
70s behind the front. Mild dry weather is expected for Wednesday
morning with lows near 50 with clear skies.

Marine...
A Small Should Exercise Caution has been post tor tonight into
tomorrow afternoon. Winds and seas have increased as the gradient
has tighten ahead of the front with seas of four to six feet
on southerly winds. Winds swing around to the north tomorrow
morning and remain elevated into the afternoon hours.

19

LONG TERM [Thursday through Monday]...

A progressive flow regime will continue through the long term period
acrs the CONUS. Although a series of shortwaves will traverse the
region the first few days of the period, temperatures are not
expected to vary significantly, and should stay near or just abv
seasonal normals.

With sfc high pres east of the region, southerly low level flow will
become further established on Thursday as lower pres develops over
the southern plains, with moisture quickly increasing and deepening
over the region. Precip water is progged to climb from ~0.4-0.5
inches Thursday morning to between 1.2 and 1.4 inches late in the
day. Rain chcs should stay low through much of the day, but a few
warm advection streamer showers will be possible by late in the aftn
into the evening.

There remains some discrepancy among global models with respect to
the track of the sfc low Thursday into Thursday night, with the GFS
a more progressive and northerly outlier compared to the
ECMWF/CMC/UKMET that align along a more southerly track. This
produces some differences in the timing of the front and its
associated wind shift on Friday, however the NBM continues to show
good agreement with a consensus of models.

The disparity may be more impactful to the potential for severe
weather Thursday night into Friday, and this will continue to be
monitored over the next few days. Shear profiles are certainly
favorable for supporting rotation/storm strength, along with steep
midlevel lapse rates. But CAPE values remain elevated and rather
modest and there is still uncertainty regarding overall evolution.

Drier air will quickly overspread the region behind the front on
Friday, with rain chcs ending from west to east. High pres building
into the area will provide for dry and pleasant conditions for the
weekend. Temperatures in the wake of the front will be slightly
cooler Friday night through early Sunday, with lows in the middle
and upper 40s acrs much of the area Saturday and Sunday mornings,
and highs on Saturday around 70 degrees.

The sfc high will quickly shift east by Sunday, with southerly winds
returning to the region. A modest shortwave ridge will translate
acrs the area ahead of a more amplified trough developing over the
western CONUS. This system will continue to strengthen into early
next week, with more robust moisture return expected Monday in
advance of the developing sfc low over the S plains. Showers and
storms are expected to increase on Monday, and guidance continues to
hint at the possibility some strong to severe storms just beyond the
long term period.

MARINE...

A moderate to strong onshore flow is expected today as low
pressure approaches. Another cold front, much weaker this time,
is forecast to move through the coastal waters Tuesday, bringing
increased chances of showers and a few thunderstorms. Expect
elevated offshore flow in the wake of the cold front Tuesday,
with winds diminishing by midweek as high pressure builds over
the region.
