Area Forecast Discussion
National Weather Service Lake Charles LA
1241 PM CDT SUN MAY 29 2016

.AVIATION...Limited moisture available across the forecast area
so will be maintaining a dry forecast. VFR will prevail with the
exception of the potential for late night fog with visibilities
possibly dropping down to within MVFR.

.PREV DISCUSSION... /issued 1015 AM CDT SUN MAY 29 2016/

UPDATE...
The patchy fog has lifted, therefore updated the zones to remove
fog wording for the remainder of the day. No other changes needed
at this time. 29/12z KLCH upper air sounding shows dry air in the
mid levels that will keep convection very limited during max
heating this afternoon.

PREV DISCUSSION... /issued 603 AM CDT SUN MAY 29 2016/

AVIATION...Patchy fog is affecting some terminals this morning,
however the fog will burn off quickly after sunrise. After the fog
burns off vfr conditions are expected, by high clouds will remain
in place through much of the day. light south to se winds are
expected today.

PREV DISCUSSION... /issued 445 AM CDT SUN MAY 29 2016/

DISCUSSION...
Light winds and a moist near surface layer has resulted in patchy
fog formation across the region overnight. This fog should erode
quickly after sunrise. Otherwise, just seeing some high cirrus
blowing overhead from convection over central TX.

Deep layer ridging, albeit somewhat flat aloft, is expected to prevail
for the next few days, yielding minimal and mainly diurnally
driven convection with temperatures near or just above seasonal
normals.

The ridge is progged to begin eroding Tuesday as an upper low
currently near southern CA ejects eastward. Global models are
having difficulty resolving how entangled/phased this feature will
be with the northern stream, but generally agree that it will be
left behind by an initial shortwave trof, then subsequently
dig/deepen over eastern TX toward the end of the week. This
solution differs from last nights model runs which had the trof
east of the area by late Friday and depicted a mostly dry weekend.
Should this morning`s scenario come to pass, several days of
active/rainy weather would be on tap for the Day 4 to 8 time
period.

MARINE...
High pressure at the surface will continue to ridge across the
northern Gulf of Mexico. This will allow a light to occasionally
moderate onshore flow to prevail for the remainder of the holiday
weekend and into early next week.
