Area forecast discussion, Jun 4, 10:41 AM CDT, 1 hour 25 minutes before
Area Forecast Discussion
National Weather Service Lake Charles LA
1041 AM CDT SAT JUN 4 2016

.UPDATE...
A line of showers and thunderstorms with very heavy rain is in
the early stages of moving ashore across southeast Texas and
southwest Louisiana. Behind the line...a broad area of rain
following on the heals of this line of thunderstorms will ensure
that most of Louisiana will also see increased probability of
rain for the rest of today. Updated pops areawide. Zone forecast
update has already been issued. The marine waters forecast was
also updated for increased pops.

Temperatures are in a stable to downward trend where the rain is
falling...while the rain free areas are inching up to their
forecast highs. Updated hourly temperature and dewpoint forecasts
to get more in line with current approaching rain shield.

Busy day ahead. Good luck all. Remember...Flash Flood Watch is in
effect. Stay safe on the road and avoid water covered roads of
unknown depth..turn around don't drown. One more thing if I may
add...please keep the kids away from the ditches and
streams...they can become dangerous when the flood rains hit.

&&

.PREV DISCUSSION... /issued 646 AM CDT SAT JUN 4 2016/

AVIATION...
Low ceilings arcoss the area outside of precip activity...but
with some heating ceilings expected to rise. Also acivity in
Jefferson county lifting to the northeast and towards BPT. This
will bring gusty winds... lightning... brief heavy rainfall...
along w/ lower ceilings. This type of activity to spread across
se Tx and srn La tdy.

PREV DISCUSSION... /issued 305 AM CDT SAT JUN 4 2016/

DISCUSSION...
Looks like one more day for heavy rain potential across the area
as upper low over Texas continues to drift south and becomes more
of an open trof. Showers and thunderstorms currently along the
southeast Texas coast will continue to expand east and northeast
along a coastal boundary.

Heaviest rain threat looks to be closer to I-10 today, however
some potential still exists up in the northern portions of the
area as well. Will maintain the flash flood watch through 7 PM.
Rain chances gradually diminish into early next week as high
pressure ridge takes over. With the diminishing cloud cover and
northerly low level flow, temperatures will begin to warm into the
90s next week.
