.SHORT TERM...
(Today through Saturday night)
Issued at 508 AM CST Thu Dec 25 2025

Areas of dense fog will persist through mid morning today before
gradually lifting and mixing into broken low clouds. Do expect skies
to become partly sunny by the afternoon with very warm highs in the
upper 70`s areawide. A high pressure cell remains centered over the
northeast Gulf while mid and upper level ridging helps subsidence
warming near the surface under the established southerly flow.

Another round of patchy fog later becoming widespread areas of dense
fog likely to take place Christmas night into Friday morning. Those
using roadways during the overnight or early morning hours are
strongly encourage to take caution during commutes in heavy fog. A
fairly strong upper level ridge begins to shift east into the north
central Gulf while the Pacific Northwest seeing lowering of pressure
heights associated with the next system that will affect us in the
long range. Meanwhile highs will trend 15-20F above normal while
lows remain 12-18F above normal for late December both Friday and
Saturday. No precipitation in the forecast for the short range
outlook.

.LONG TERM...
(Sunday through Thursday)
Issued at 508 AM CST Thu Dec 25 2025

The long range outlook will show a noticeable shift in the pattern
back to cooler cooler weather through the start of the New Year. A
deeply amplified shortwave trough will expand across the Heartland
Sunday with an associated cold front moving through the local area
that night into early Monday. Highs will range broadly 50-60F
behind the front, as a strong pressure gradient develops
southward offshore leading to very windy/gusty offshore breezes.
Confidence is growing that at minimum, areas along or north LA
HWY 190 will have a decent shot at observing temperatures at or
below freezing Monday night. Combined with breezy north winds and
windchills may fall into the low 20`s for portions of CenLA. This
colder airmass will stick around through next Tuesday before
temperatures begin to moderate by the middle of the week as
surface high pressure broadens to the east.

.AVIATION...
(12Z TAFS)
Issued at 508 AM CST Thu Dec 25 2025

Widespread LIFR conditions due to VIS and CIGs are ongoing.
Conditions will slowly improve with sunrise, however, improvement
to VIS greater than 1 SM may not occur until after 16z due to the
thickness of standing marine/radiational fog layer.

Gradient will begin picking up today between developing low in the
cenUS and high pressure to the east. This will assist with mixing
out conditions from late morning to early evening. After sundown,
low ceilings and fog will develop once again. Probabilities for
widespread dense fog are lower into Friday morning simply due to
boundary layer winds staying up during the night. If those winds
are lower than anticipated, though, dense fog may set in quickly
after sundown, particularly for coastal terminals.
