Area Forecast Discussion
National Weather Service Lake Charles LA
1040 AM CDT Mon Apr 19 2021

.DISCUSSION...
Other than nudging up temps a degree or so based on latest
readings from around the region and updated guidance, few changes
to inherited grids/zones were made this morning as all appeared
to be in line based on going trends.

.PREV DISCUSSION... /issued 636 AM CDT Mon Apr 19 2021/

DISCUSSION...
12Z TAFS

AVIATION...
VFR conditions will prevail through the period. Surface high
pressure will continue to build into the area today from the west
resulting in light northeasterly winds. Modest upper level
moisture will result in SCT high clouds traversing the region
within the westerly flow aloft with this cloud cover becoming more
dense overnight.

PREV DISCUSSION... /issued 245 AM CDT Mon Apr 19 2021/

DISCUSSION...
Wx map shows 1020 mb sfc high over East Texas with light northerly
flow to calm winds over the inland locations, still around 10-15
kts from the coast into the coastal waters. Satellite imagery
still showing Ct/bkn cirrus roughly along and south of the I-10
corridor into the Gulf. Temperatures range from the mid to upper
40s north of I-10 with mostly clear skies and calm winds to the
lower/mid 50s along the I-10 corridor of SE TX/S LA.

Clouds expected to thin out a bit more, leaving mostly sunny
skies for today and highs in the lower 70s expected. Clouds will
be on the increase later overnight into Tuesday ahead of the next
cold front, which is expected late Tuesday night into early
Wednesday morning. For a change, no precipitation is expected with
this frontal passage, but will see even cooler air filter across
the region Wednesday into Thursday morning, where temperatures are
expected to average around 10-12 degrees below normal for morning
lows and daytime highs.

By Thursday afternoon, the surface high will slide east of the
region, with east to southeast winds returning by Thursday
evening into Friday as the front lifts back northward. The wind
pattern aloft, mainly zonal for most of this week, will feature a
significant shortwave to move west to east by Friday into Saturday
across the region. With this, along with the retreating warm
front, ArkLaTex surface low, and Gulf moisture, will come high
precipitation chances by Friday afternoon into roughly early
Saturday morning. Little too early to determine specifics, such as
possibility of severe weather. However, with the quick movement,
the multiple day rain event like last week seems unlikely at this
time. Expect diminishing chances of precipitation and slightly
cooler air behind the front by Saturday afternoon into Sunday.

DML

MARINE...
Light to modest offshore winds are expected to continue through
mid week with the passage of another cold front late Tuesday into
Wednesday. Onshore flow is expected by late Thursday into Friday
as the front moves back north, along with increased chances of
showers and thunderstorms by Friday afternoon and evening.
