.DISCUSSION...
Issued at 1208 PM CST Sat Jan 24 2026

Well... it`s here. While there is still time to do preparations,
time is starting to run out to do so while you can still feel your
fingers. A drastic change in temperatures (72F at 0640 AM down to
52F within 25 minutes) has settled in across South Texas. Since
the frontal passage, most locations have seen steady temperatures
in the upper 30s to 40s. Additionally, the rain/thunderstorms
associated with the front brought many inland locations have
brought wet surfaces throughout the area. At the same time, winds
behind the front have been gusting 20-30 mph out of the north.
This is helping dry up some of the surfaces already, which will be
of great benefit this evening with a light freeze in store.
Tonight, an additional bout of precipitation chances will bring
the low-to-moderate chances of freezing rain for locations within
the Winter Storm Warning (and more so north of Hwy 59); CAMs such
as the latest runs of the HRRR continue to keep the bulk of the
showers associated with freezing rain moving through Victoria
after 10Z, but quickly wrapping up after 13Z, so the period of ice
accumulation will be a short one. Storm total ice accumulations
did not change much from the previous package and the Winter Storm
Warning is still advertising up to a tenth of an inch of ice
accumulation for Goliad/Victoria Counties. Then we are done with
the the threat of ice falling from the sky and quickly shift focus
to any freezing of wet surfaces, but Sunday morning duration of
temperatures below 32F will be limited to under 2 hours south of
the Corpus Christi area, with longer durations N of Hwy 77
(approaching 8-12hrs).

For this reason, no additional changes were made to the hazards
that were issued with forecast package issued before this one (I
have included the well-written discussion below for your quick
reference). While no decision was made to any expansion of the
Extreme Cold/Freeze warnings beyond Monday afternoon, it is
expected that these will be considered/issued overnight (once the
frozen precipitation threat falling from the sky moves away from
South Texas).

.DISCUSSION...
Issued at 1247 AM CST Sat Jan 24 2026

The strong arctic front has now plunged south of San Antonio and
east of Eagle Pass on the swinging backside, trending faster than
previous model runs. The front will likely reach our northern
counties from La Salle to Victoria in just a couple hours, then
continue to rush southward extending passed Baffin Bay by 9 AM
this morning. We`ll maintain a medium to high chance for showers
and a lower chance for thunderstorms through this morning, before
we get weaker coverage of overrunning showers in the afternoon.
High temperatures today have dropped to account for the faster
progression. Honestly, the highs in the climate for today are
likely occurring right now.

Another wave of showers and a few thunderstorms will pass over
tonight into Sunday morning as the mid-level trough drapes across
Texas. During this time, PWATs will continue to run above-normal
(75-90th percentile) at 1.25-1.5" while CAA cause temperatures to
lower. While model guidance was in fairly good agreement with
freezing temperatures and periods of freezing rain where the
Winter Storm Warning is in effect, there was less agreement south.
Primarily, models varied on how far south freezing temperatures
extend but generally agreed with precipitation lingering through
Sunday mid-morning.

Considering that temperatures are colder than recent runs looking
upstream throughout the past several hours and FROPA keeps
speeding up, I am more concerned we are underestimating just how
far south freezing temperatures will make it. Therefore, a Winter
Weather Advisory has been issued for the rest of South Texas with
the exception of the islands. It`s definitely not out of the
question for temperatures to reach freezing across the region, and
if it does, roads will likely be wet from rain during the day.
These wet roads can freeze, especially on bridges and overpasses,
creating black ice and dangerous conditions. Black ice and the
brief window of light freezing rain early Sunday morning warrants
a Winter Weather Advisory mention.

Early morning lows Monday and Tuesday look to be extreme and
likely record breaking, dropping into the teens inland and to the
low-mid 20s along the coast and Rio Grande. An Extreme Cold
Warning applies everywhere Monday morning with wind chills
dropping in the single digits over the inland Victoria Crossroads
and the low to mid teens elsewhere.

Temperatures warm back into the 50s and 60s mid-late next week but
another cold front will likely swing across Wednesday to Thursday,
bringing near freezing conditions again. However, moisture will
struggle to return and therefore have no precipitation chances
mentioned.

.AVIATION...
(18Z TAFS)
Issued at 1208 PM CST Sat Jan 24 2026

The strong arctic front moved through the region, bringing with
it widespread MVFR to IFR CIGs/VSBYs, periods of showers, and
gusty, northerly winds. Winds will veer to the north- northeast
at speeds of 10-15 knots with occasional gusts up to 25 knots. Low
CIGs will continue and rain showers will linger through much of
the period. By approximately 06Z Sunday, we`ll be monitoring for
the potential for freezing rain through roughly 12z. Confidence is
moderate for the northern Coastal Plains and Victoria Crossroads,
but low confidence exists for the southern areas due to timing of
the arrival of the freezing temperatures compared to when the
precipitation moves into and out of the area. Included mention of
FZRA for COT/VCT, but depending on updated trends later this
evening, may need to add additional sites (ALI/CRP) if confidence
in southward extent increases.

.MARINE...
Issued at 1208 PM CST Sat Jan 24 2026

A strong to near Gale (BF 6-7) north wind has settled in behind a
strong arctic front. Small Craft Advisory conditions are expected
through Monday. Gust to gale will be possible at times,
especially Sunday night. Rain chances will increase to a moderate
to high chance and continue through Sunday morning. Temperatures
will be around freezing along the coast with wind chill values
feeling well below freezing during late Saturday night through
Monday morning. Gentle to moderate onshore flow briefly returns
the middle of next week before another cold front threatens to
push through.

&&

.FIRE WEATHER...
Issued at 1208 PM CST Sat Jan 24 2026

Moisture levels across South Texas will continue to be elevated
ahead of the greatly advertised arctic front. Minimum RH vales are
expected to stay mostly above 30% through mid-week next week, with
the exception of Monday and Tuesday when values may briefly dip to
25-30%. However, light winds should prevent any meaningful fire
weather concerns. As for precipitation, chances remain medium to
high through Sunday morning, with only an isolated thunderstorm
potential tonight. Overall, no fire weather conditions are expected.
