Area Forecast Discussion
National Weather Service Lake Charles LA
412 AM CST Tue Feb 14 2017

.DISCUSSION...
Water vapor imagery shows the cutoff low moving out of the Four
Corners Region and into West Texas this morning with attendant
shortwave crossing the Rio Grande into Deep South Texas. Sfc
analysis shows an associated low developing near KBRO with another
noted near KPSN...with a warm frontal boundary slinking sewd into
the forecast area. Regional 88Ds show widespread rain with a few
embedded heavier showers ongoing over cntl/wrn Texas in
proximity to the upper support, while closer to home maybe a few
streamer showers are noted moving in off the Gulf in the warm air
behind the nwd retreating boundary. Otherwise a warm cloudy
morning is ongoing over the region.

Not many changes to the inherited grids/zones this morning as we
still expect a possible heavy rain/severe event beginning late
morning but mainly during the afternoon/early evening hours. The
mid/upper-level storm system will continue pushing ewd through
Texas today, with its sfc reflection following suit by moving
through sern Texas and cntl Louisiana by evening. Enhanced lift
from these features will work in concert with increasing deep
moisture and weak destabilization in the warm sector to produce
widespread convection later today, mainly along/near the attendant
cold front. Recent model runs have been trending slower on the
onset of convection...now looking more like the noon hour for our
extreme wrn areas with the storms eventually pushing towards the
Atchafalaya by early evening. Forecast soundings continue to
indicate sufficient CAPEs and decent lapse rates along with good
directional shear, especially over our swrn zones...for that,
severe wording has been maintained in the grids/zones through the
day as convection makes its ewd path across the forecast area. The
nwrn portion of the CWA has been included in WPC's slight risk
for excessive rainfall today with forecast mean QPFs well
exceeding an inch...although locally higher amounts are certainly
possible.

Precip should gradually end from west to east with the last
showers/storms crossing the Atchafalaya late this evening. Drier
and cooler air should be the rule for Wednesday and Thursday as
we lie under a nrly flow aloft and the next sfc high gradually
builds past. Medium range models are a little more aggressive
today with the next storm system dropping through nrn Mexico
before eventually moving into the wrn Gulf region for Friday and
Friday night, accompanied by scattered showers. With a rather
progressive pattern in place, another round of showers/storms
looks on tap for late in the weekend and into Monday.

&&

.MARINE...
A Small Craft Advisory has been hoisted for later today and on
into Wednesday for the outer coastal waters as increasing
wrly/nwrly flow develops behind the low/sfc front.

Hazardous Weather Outlook
National Weather Service Lake Charles LA
600 AM CST Mon Feb 13 2017

East Cameron-Tyler-Hardin-Jefferson-Orange-Northern Jasper-
Northern Newton-Southern Jasper-Southern Newton-
600 AM CST Mon Feb 13 2017

This Hazardous Weather Outlook is for portions of central
Louisiana, south central Louisiana, southwest Louisiana, west
central Louisiana, and southeast Texas.

.DAY ONE...Today and Tonight
A few showers associated with a passing cold front will be
possible mainly near the coast this morning...otherwise dry
weather will prevail through tonight as high pressure builds over
the region.

.DAYS TWO THROUGH SEVEN...Tuesday through Sunday
A storm system aloft developing over Mexico will gradually lift
eastward toward the western Gulf States through Tuesday. This
upper low will help induce low pressure to develop at the
surface over Southeast Texas, which is then expected to move
eastward across Central Louisiana Tuesday evening. The combination
of these low pressure areas with improving Gulf moisture will lead
to numerous to widespread showers and thunderstorms beginning late
morning across Southeast Texas, then spreading eastward across
Southwest Louisiana through the afternoon and early evening. A few
of the storms could reach severe limits, with the primary
concern being damaging wind gusts. However conditions appear such
that tornadoes cannot be ruled out. Heavy rainfall also looks
possible, especially across interior Southeast Texas and Central
Louisiana...with average rainfall amounts running up to 2 inches.

Dry weather is expected the remainder of the period once this
storm system passes the region.

.SPOTTER INFORMATION STATEMENT...
Spotter activation may be required.
