.SHORT TERM...
(Today to Sunday Night) 
Issued at 323 AM CDT Fri Oct 7 2022

Outside of fog, we have a quiet start to the day with temperatures
in the mid 50s to low 60s under clear skies. Winds are calm with
dewpoints falling a few degrees below or matching air temps. 
Patchy to dense fog can be seen this morning across the coastal 
Counties of SETX, Calcasieu Parish, and Cameron Parish. 
Visibilities under a mile are noted, so please travel with 
caution early this morning. Fog will be quick to burn off after 
sunrise. There is an Air Quality Alert, from 7 AM to 7 PM CDT 
today for the Golden Triangle Counties. That will begin to clear 
out as the front starts to drop down into the area. Other than 
those things, nothing new and noteworthy to mention.

The cold front will bring slightly cooler and drier air into the
region, however no rain. We are pretty dry so the front will not 
have much in the way of moisture to work with. At the most we will
see mid to upper level clouds shortly before frontal passage with
clouds quick to clear out tomorrow morning to afternoon. The 
front will do little to the afternoon temps, however it will help 
in cooling us down more at night. Temps today (pre front) will be 
in the 90s, while this weekend (post front) they will be in the 
mid to upper 80s. Tonight's lows will be in the mid to upper 60s, 
with some low 70s along the immediate coast. That will be brought 
down to the mid to upper 50s after fropa. 66 Stigger

.LONG TERM...
(Monday through Friday) 
Issued at 323 AM CDT Fri Oct 7 2022

The upper air pattern Monday through Wednesday becomes more zonal
with the cool surface high slowly sliding eastward. The easterly 
winds will gradually become southeast, gradually increasing the 
dewpoints and humidity across the area. Overnight lows a little 
higher in the mid 50s to lower 60s Tuesday morning, upper 50s to 
mid 60s Wednesday, and mid 60s to near 70 on Thursday morning. 
Highs in the mid to upper 80s Monday through Wednesday. Chances of
showers and a few thunderstorms expected to return on Wednesday 
with increased moisture from the Gulf, 20-30% range north of I-10,
and 30- 40% south of the interstate to the coast, and 40-50% 
across the coastal waters. 

By Thursday and Friday, a large longwave trough expected to dig 
southward across the Central and Eastern U.S. This will bring 
another cold front across the area late Thursday night. The 
approaching front and lingering Gulf moisture will keep chances of 
showers and thunderstorms around 30-40% during the day Thursday, 
with highs in the mid to upper 80s. Behind the front, cooler and 
drier air expected to return to the region on Friday.
