UPDATE...
Beautiful night out tonight... some high CI is streaming in on 
the subtropical jet as temperatures continue to slide towards
morning lows. Clouds may make it a bit hard to observe the
Geminids meteor shower tonight. But we will still have another 
chance tomorrow evening. Tonight...looking for below freezing 
temps in the lakes region and acrs central Louisiana twrds 
sunrise. Mid 30s along the I-10 corridor and near 40s at the 
beaches.

Look for another dry front on Thursday morning. This is keep the
region on the cool side into the weekend when yep... another 
front comes down into the northwest gulf. The big key is that 
this front looks to bring showers back into the forecast late 
Saturday into Sunday with rains ending on Monday. But Sunday's 
high expected in the low 70s prior to the frontal passage.

Current zones are fine... no updates planned.

PREV DISCUSSION... /issued 254 PM CST Tue Dec 12 2017/ 

DISCUSSION...
Nice winter day across the region with temperatures in the low to
mid 60s with strong sun. Temperatures will cool rapidly overnight
with good radiational conditions setting up.

Gradual warming trend expected through Thursday when the next cold
front is expected to move through the area. There may be a few
showers in the coastal waters and in extreme SC Louisiana
Thursday/Thursday night. 

Deep trough still expected to gradually move east this weekend
into early next week. This will allow good moisture return to the
region along with a good chance of showers and thunderstorms.
There are still model differences on the start time
Saturday/Saturday night and especially on the ending sometime
early next week. May eventually need to add some POPs to the
daytime forecast Saturday, but choose to wait til model confidence
increases a bit. Front still looks to move through on
Sunday/Sunday night.
