.SHORT TERM...
(Tonight through Friday night)

Wx map shows surface high pressure ridging across the Gulf, keeping
southerly winds 5 to 10 mph across the area. Further north, a
warm front across the ArkLaTex separates our warm humid airmass
across our area with the much colder temperatures north of the
boundary. Satellite imagery showing partly cloudy skies across the
area. Temperatures this afternoon continued to rise, having
reached near 80/lower 80s over most locations, which have already
broken or tied record highs here in Lake Charles, Lafayette, New
Iberia, and possibly Beaumont. This will be confirmed on the
evening climate product run after 4 PM.

For tonight, main issue will continue to be the areas of marine fog
expected to become more dense across the coastal waters and
spread inland over the coastal parishes and counties. The Dense
Fog Advisory continues for the inland lakes, bays, and coastal
waters through Noon Thursday, with the coastal parishes/counties
from Midnight through 9 AM Thursday.

The mid to upper level pattern expected to remain zonal across
the mid and northern U.S. with mid to upper level high pressure
extending across Mexico and the Gulf. This will keep much above
normal temperatures across the area. With little influence from
any shortwaves north of the region, not expecting any significant
precipitation. The main issues will be marine dense fog likely to
persist or reform during the evening and overnight hours. Early
signals shows the fog becoming more of a problem and spreading
further inland Thursday night into Friday morning.

.LONG TERM...
(Saturday through next Tuesday)

The mid to upper level pattern expected to slowly transition as a
deep layer trough digs further southward across the Southwest U.S.
by early next week. Warmer than normal temperatures will continue
through the weekend. A cold frontal boundary expected to move through
the area late Sunday into Monday morning, with temperatures falling
closer to slightly below normal. The frontal boundary, along with
increased moisture and lift, will increase the chances of showers
and a few thunderstorms across the area Monday and Tuesday.

(00Z TAFS)
Issued at 534 PM CST Wed Feb 5 2025

CIGs/VIS will begin to deteriorate across the I-10 terminals
through the next few hours, with most (if not all) of those sites
expected to tank to LIFR prior to midnight. Thereafter, guidance
is a bit spread on if CIGs/VIS will improve a bit (similarly to
last night) or remain IFR/LIFR. Regardless, at least some fog
will linger through sunrise tomorrow, with all sites expected to
be MVFR to LIFR from midnight through roughly noon tomorrow. Fog
should lift somewhat quickly with sunrise but ceilings will be
slower to improve. By tomorrow afternoon all sites will return to
VFR.

&&

.MARINE...

Dense marine fog expected to reform later this afternoon and
evening, with visibilities lowering to less than one nautical
mile across the nearshore waters, lakes and bays. The Dense Fog
Advisory continues through Noon Thursday. Otherwise, high
pressure over the Eastern Gulf will keep light onshore flow
through the period. Areas of dense fog may be possible once again
Thursday night into Friday morning.
