From SCW:

“Is This Week Houston’s Last Shot At A Freeze For The Winter Of 2022-2023?

Here’s the short answer up front: Probably. Barring some kind of an unexpected, freakishly cold front coming through in the next few weeks, we’re done.”

...New AVIATION...

.SHORT TERM...
(Today through Thursday Night)
Issued at 341 AM CST Wed Feb 15 2023

Dense fog will linger through the mid morning for areas along and
south of I-10 with patchy dense fog all the way up to Conroe. While
the fog over the land will dissipate this morning, patchy dense sea
fog will persist over the Bays and near shore waters into tonight.
Today will feature overcast skies, temperatures in the upper 70s to
near 80, and isolated afternoon showers. There will be a lull in the
showers activity this evening, but PoPs increase overnight as a cold
front moves through the area. This cold front is associated with an
upper level low that will be moving through the Four Corners this
morning and into the Central Plains this afternoon. FROPA will occur
in BCS around midnight to 2am, Houston Metro around 3am to 5am, and
then off the coast between 6am and 9am Thursday morning. A line of
showers and thunderstorms will accompany the cold front with the
potential of one or two strong thunderstorms. Conditions are not
super favorable for severe weather with a lack of surface heating
(better environmental conditions north and east of SE Texas where
the front will have access to daytime heating). However, CAPE values
around 1500 J/kg, SFC-3km lapse rates around 6 C/km, and EBWD values
between 50 and 60 kts will mean the strong thunderstorm risk is not
zero. SPC has placed areas north of I-10, but east of I-45 in a
Marginal Risk of severe thunderstorms tomorrow morning with all
severe hazards possible.

Low temperatures tonight will range from the mid 40s to low 50s
across the northwestern portion of the region to upper 50s/low 60s
in the southeastern portion of the region where the cold front will
not cross until close to sunrise. CAA behind the front will mean
high temperatures on Thursday will be about 15 to 20 degree cooler
compared to today with temperatures only getting into the upper 50s
to mid 60s across the area. Breezy conditions will build in across
the area on Thursday with sustained winds around 15 to 20mph with
gusts up to 25 to 30mph. Winter temperatures make a return Thursday
night as low temperatures drop back into the low to mid 30s across
most of the area.

.LONG TERM...
(Friday through Tuesday)
Issued at 341 AM CST Wed Feb 15 2023

Fairly benign wx is expected with cool conditions prevailing into
Saturday. We should see a warming trend Sunday into early next week
as surface high pressure moves east of the area and onshore winds
bring a return of Gulf air back into the region. Temps in the 30s
at night and 50s during the day will quickly transition to the lows
in the 60s to highs near 80 by Tues. Medium range models differ on
rain chances early next week, which are somewhat dependent on the
progression of the next western trof. Have maintained NBM suggestions
with some lower end POPs in the fcst to account for some waa type shra
and/or disturbances riding across in the sw flow aloft. 47

.AVIATION...
(12Z TAF Issuance)
Issued at 525 AM CST Wed Feb 15 2023

LIFR to IFR conditions will persist through the morning as CIGs
remain between 400 and 800ft and patchy fog. The densest fog is
along the coast impacting LBX and GLS with visibilities down to
1/2 mile or less. While the foggy conditions will improve through
the morning for in the inland terminals, GLS may see periods of
fog all day. Fog begins to redevelop across the area tonight ahead
of an approaching cold front. CIGs through the day will rise to
about 1500 feet by the mid morning, then remain there through the
day until lowering back down to around 700ft this evening.
Scattered showers and a few rumbles of thunder will be possible
today as warm front slides through the area. Chance of showers and
thunderstorms increase tonight as a cold front slides through the
area. This front will move through CLL between 6 and 8z, IAH
around 10 to 12z, and then through GLS between 12 and 14z bringing
not only a line of showers/thunderstorms, but will also shift the
winds from the south to the northwest. VFR conditions will develop
by the mid to late morning across the area on Thursday with breezy
northwesterly winds through the day.

.MARINE...
Issued at 341 AM CST Wed Feb 15 2023

Although winds are lighter, elevated seas will continue in the
offshore waters today. Small Craft Advisories beyond 20nm will
need to be converted to Cautions later this morning once seas fall
below 7ft. Otherwise, sea fog in the bays will retreat southward
into the Gulf later this morning and early afternoon. Reduced
visibilities will likely persist off the beaches throughout the
day. It will roll back into the bays early this evening. A cold
front will push off the coast between 5am and 8am Thursday and
will sweep the fog away, but strong offshore winds and building
seas are expected in its wake. Some gusts to gale may occur,
particularly west of Freeport and also offshore. Debated issuing a
Gale Watch west of Freeport, but decided to let the dayshift take
another look with the next round of model data. Low water
conditions in the bays are likely by early Friday. Gradually
improving marine conditions are expected this weekend as light
onshore flow resumes. 47

This winter has been disjointed with warm and a few cold spells, but overall average in CLL. There will be about 12-13 lows of 32°F or less. Also, a low of 13°, which is unusual for College Station, although we've had 3-4 lows below 15° in the past few years. Two, including a low of 5°F during the Feb 2021 winter storm.

In short, just another weird La Nina "winter."

It's hard for me to type the word "winter" and keep a straight face when it comes to SETX. I consider our winters "Fall" with occasional polar or arctic intrusions. They're a joke.

Keep in mind that El Nino winters are not necessarily colder in SETX, but they are a lot more rainy. Neutral ENSO would be fine.

.AVIATION...
(18Z TAF Issuance)
Issued at 1123 AM CST Wed Feb 15 2023

Cigs and vis have been slow to improve, but should still become
MVFR for most inland locations today once southerly winds pick up.
After 00Z, cigs will quickly become IFR again and fog will push in
as well. GLS is currently VFR, but still expecting to see
intermittent vis becoming IFR/LIFR today then prevailing IFR/LIFR
after 00Z tonight. A cold front will reach CLL around 06-08Z and
push its way to the coast by 12-14Z. We can expect some scattered
showers tonight ahead of the front and then a line of shower and
thunderstorms with the front itself. Cigs will quickly improve to
VFR behind the front and northerly winds will be gusting up to
25-30kts.

May - September are pretty much suck in CLL. Humid, hot, and flood or no rain at all for weeks. :lol:

Too much A/C running and sprinklers with Na+ laden water requiring backs of high nitrogen fertilizer with 2% iron (Sta-Green, not Scotts) draining my pocketbook.

81°F and DP of 65°F. Welp, the A/C is on. Not a good winter day for me. :roll:

At least yesterday had a low DP and felt pleasant.

...New AVIATION...

.SHORT TERM...
(Today through Friday Night)
Issued at 319 AM CST Thu Feb 16 2023

Cold front and associated band of showers will be pushing off the
coast early this morning. Precip should mostly end with the frontal
passage, though some guidance indicates a mid level disturbance
coming up from the southwest later in the afternoon. It may squeeze
out some sprinkles or -ra should they be able to survive the
drying/deepening sub cloud layer. Otherwise, highs today will be
observed early this morning. Look for falling and/or steady temps
for the remainder of the day considering CAA and lack of sunshine.
Breezy nnw winds are expected and it appears that coastal portions
of the area will reach wind advsy criteria so will go ahead and
issue that into the mid evening hours. Clouds will gradually clear
from north-south this evening and overnight. Winds will probably
keep most areas above the freeze mark, though locations generally
north of a Brenham-Livingston line might see a few hours of a light
freeze.

Continued cool and somewhat breezy on Saturday with highs struggling
to reach the mid 50s. Winds will begin settling down Friday night as
high pressure moves into northeast Tx. Conditions should be a bit
more favorable for a light freeze north of Highway 105 Friday night.

.LONG TERM...
(Saturday through Wednesday)
Issued at 319 AM CST Thu Feb 16 2023

The chilly conditions will persist through Saturday, but there
will be a gradual warm up On Sunday as the high pressure slides
to the northeast ushering in a southeasterly flow. High
temperatures on Saturday will climb into the mid to upper 50s with
lows Saturday night down into the upper 30s to low 40s.
Temperatures on Sunday will increase by about 10 to 15 degrees
with high temperatures in the low to mid 70s and low temperatures
in the mid to upper 50s Sunday night.

By the start of the new work week, an upperlevel low will be
moving into Baja California from the Pacific and continue to push
eastward through midweek. This will increase moist southerly flow
into the region bringing high temperatures Monday through
Wednesday into the low to mid 80s. There may be some isolated rain
showers that pop up Tuesday afternoon as that moist southerly air
moves into the area. That upper level low will swing through
Texas on Wednesday bringing an increase in showers and
thunderstorms to the region as the associated cold front pushes
through.

MVFR & borderline IFR conditions ahead of the cold front and
associated band of showers currently making their way across the
metro airports. The front & precip should make its way off the
coast by mid morning. Gusty north-northwest winds 15-30kt are
anticipated in the wake of the front. Ceilings will gradually lift
thru the day...becoming VFR across the majority of the region in
the late morning hours. Clouds begin clearing/scattering out
overnight. 47

.MARINE...
Issued at 319 AM CST Thu Feb 16 2023

Patchy fog will linger through the early morning, but a cold
front will push through the coastal waters during the mid to late
morning ending the sea fog potential. This cold front will usher
in moderate to strong offshore flow through tonight. A Gale
Warning will go into effect this morning for the offshore waters
where sustained winds of 20 to 30kts will develop with frequent
gusts up to 40kts. Small Craft Advisories are in effect for the
Bays and nearshore waters where there will be sustained winds of
15 to 25kts with gusts to 30 to 35kts. The near shore waters will
be borderline Gale conditions. There will be gusts to gale, but
shouldn`t be frequent enough to warrant the Gale Warning. If the
winds end up being stronger than expected, then the SCA may get
upgraded later today to a Gale Warning. The strong winds will
increase wave heights to 4 to 8 feet in the near shore waters and
to 5 to 11 feet in the offshore waters. Moderate northwesterly to
northerly winds will continue through Friday night with seas
decreasing to 3 to 5 feet. High pressure over the weekend will
bring relatively benign weather to the coastal waters.

This persistent offshore flow combined with already low
astronomical tides will cause abnormally low tides in the Bays,
especially on Friday. Low tides today will be around 0.5ft below
MLLW, but will dip down to 1.5 to 2ft below MLLW Friday morning.
Low tides around 0.5ft below MLLW will continue through the
weekend.

Our dog and I are headed out now. NNW20 G32 - it's no joke. Our son in Minnesota actually hates it when the temp gets above freezing there in the winter, because of melting and refreezing with black ice. He'd prefer no thaw until Spring when temps stay above freezing. :lol:

No surprise on the light freezes here tonight and tomorrow. That will bring me up to 13 freezes for the winter.

I dig it, but my wife is cold so I've had to crank up the heater!

...Only to turn on the A/C next Monday.

Enjoying one of my last runs outside this morning. Upper 30s and a light breeze were great. Like clockwork, my time gets so much faster when its colder. It will be back to indoor running next week for sure.

I also think we need to hold off on the winter is over comments here, just got confirmation from Pow Ponder that a Major Sudden Stratospheric warming event has taken place in the arctic, next 6-8 weeks of weather in the US could be largely influenced by that, this initial arctic intrusion out west is the beginning of a step down process, I suspect the last week of february and into march might be colder than normal across most of the US

Since this just happened yesterday, its going to take time for this to show up in the models, people are going to be awfully surprised lol
