Area Forecast Discussion
National Weather Service Lake Charles LA
1206 AM CDT TUE MAY 24 2016

.DISCUSSION...
For 06z TAF issuance.

&&

.AVIATION...
Current satellite imagery shows plenty of blowoff cirrus from
upstream convection overspreading the forecast area ATTM...
otherwise just a few lingering stratocu from daytime heating.
Forecast time-height sections/soundings indicate good low-level
moisture pooling beneath the nocturnal inversion...thus expect low
ceilings to develop later. Main story tomorrow will likely be the
elevated srly winds...although MVFR cigs could stick around longer
at KBPT...as the gradient tightens a little with low pressure
deepening over the Plains and some stronger winds aloft mix down.

.PREV DISCUSSION... /issued 1042 PM CDT MON MAY 23 2016/

DISCUSSION...Forecast on target. No update coming.

PREV DISCUSSION... /issued 326 PM CDT MON MAY 23 2016/

DISCUSSION...A ridge of high pressure remains to the east of the
region this afternoon while ridging is also occurring aloft. This
pattern will remain in place through Wednesday keeping the SE flow
in place and rain chances minimal. What few showers and storms do
develop will be mainly diurnal in nature. By Wednesday only one
or two storms may occur as the ridge is at its strongest. Early
summer temps can also be expected with upper 80s to low 90s
forecast.

Past mid week the ridge aloft will shift slightly east while a trof
moves into the SW states. A surface low will also develop along
the lee of the Rockies serving to increase the onshore flow. The
upper low will move across Rockies Thursday and Friday with pops
increasing locally as disturbances move by the base of the larger
trof.

Late in the weekend ridging through the column will redevelop
ending the elevated pops.

MARINE...A light to moderate onshore flow is expected through the
period. Winds will increase somewhat into the 15 to 20 knot range by
Friday as low pressure moves across the plains.
