Discussion...
the subtropical jet continues to stream moisture in from the
eastern Pacific as the warm front has push inland over the region.
This can be seen in the wide range in temperatures this morning
with lower 50s in the lakes region of southeast Texas with lower
60s down along the coast from Orange into Morgan City in south
central Louisiana. Areas of dense fog across a wide area of
southern Louisiana including the coastal waters. Areas of dense
fog have also spread into southeast Texas around Orange with fog
noted in Jasper. This is expected to become denser over the next
several hours. Showers are also continuing over south central
Louisiana and the adjacent coastal waters. In short it's a mess
out there.

Conditions will improve through the late morning hours but the
chances for showers and isolated thunderstorms will increase
through the day with daytime heating. Look for areas of fog to
return this evening first along the coast then inland. The threat
for storms will also linger into the evening and overnight hours.
This weather pattern will continue into Tuesday ahead of a cold
front that will move through on Wednesday morning. The weather
will improve through the day on Wednesday as fog and showers exit
off to the east and northeast. At this time the heaviest rains
look to fall across northern Louisiana and Arkansas.

We are going to get a short break but rains return on Thursday
afternoon and continue into Friday morning ahead of a stronger
cold front that will push through. That front is expected to drive
temperatures back into the 30s by Sunday morning. In addition the
threat for rains will also linger over the weekend and into
Christmas.
