Area Forecast Discussion
National Weather Service Lake Charles LA
724 PM CDT SAT MAY 21 2016

these latter prove correct, then additional updates will be
required to increase PoPs for the overnight hrs too.

.PREV DISCUSSION... /issued 645 PM CDT SAT MAY 21 2016/

AVIATION...Have opted to maintain VCTS or VCSH at our terminals
of BPT and LCH. Weak frontal boundary analyzed across coastal
south-central Louisiana, then arcing northwest through southwest
Louisiana into southeast Texas. Seeing decent moisture pooling
with this feature as weak disturbances ride in on a westerly flow
aloft. Will continue to monitor and may have to include some
mention of convection over Acadiana. Expecting VFR to hold at all
terminals through this TAF package with the exception of BPT where
some MVFR ceilings should come into play overnight.

PREV DISCUSSION... /issued 352 PM CDT SAT MAY 21 2016/

DISCUSSION...
Summer has arrived as temps around the region have climbed back
into the upper 80s with a few locations reporting mid 80s. Radar
has remain quiet across southeast Texas and southern Louisiana as
storms along the central Texas coast lift northeast and near this
region... but these storms are expected to end around sunset with
the loss of heating.

Tonight will be a bit muggy as temperatures fall back towards the
upper 60s to lower 70s. A few areas to see a bit of fog overnight
burning off around sunrise.

Tomorrow the front or what is left of the front will drift back
northward and into southeast Texas allowing the moisture profile
to deepen. Several weak shortwaves moving through the ridge will
support some storm activity in southeast Texas during the
afternoon hours. A few more storms on tap for Monday as the
boundary pulls further to the north and east opening up southwest
Louisiana to the gulf moisture.

The ridge aloft looks to begin to strengthen late Tuesday into
Wednesday this will shut down most of the precip and in doing will
allow for temps to climb a bit towards the end of the week.
