February 2021: Arctic Outbreak/Warmup Begins

[TexasBreeze]

The liquid equivalent of that model is spitting out up to an inch and a quarter precip. Impressive!

[Kingwood36]

Can anyone tell me if Angleton is considered "immediate coast line"?

Imagine if that is all snow! If that were to happen, that’s over a foot of snow.. Wowza!

Can anyone tell me if Angleton is considered "immediate coast line"?

Is there a beach out your door?

Nope..I just didn't know if they went inland so many miles or what determined it

[Rip76]

I work for a chemical trucking company and supervise drivers and employees in the Dallas and Houston areas.

We are trying to top off hospital Oxygen tanks in the next 24 hours.

As far as Dallas is concerned we are shutting it down this afternoon, but I am going over the Houston routes for tomorrow. What time will it start to freeze/ice in the Houston area?

I want them off the roads by then.

[Stratton20]

Im in katy, could I see accumulating snow?

[srainhoutx]

Surfside, Galveston and Bolivar are the immediate Coast.

Some of the short range guidance suggests the possibility of light freezing rain/drizzle overnight near W and NW Harris County and again in the morning. Freezing rain and sleet start to press in by around 4 PM or so tomorrow.

Thank you.

So if I have them off the road by 4/5pm tomorrow, we should be fine?

Area Forecast Discussion
National Weather Service Houston/Galveston TX
403 PM CST Sat Feb 13 2021

...Frigid, life and property threatening winter weather is still
expected to develop across much of Southeast Texas into Thursday...

.DISCUSSION...

* Bitterly cold air will continue moving into the region into
midweek as an Arctic airmass spills into the area. Prolonged
periods of below freezing temperatures are expected - even at
the beaches.

* Two weather systems (one Sunday night-Monday morning and
another toward midweek) will produce winter precipitation across
many parts of Southeast Texas.

* Travel will be impacted by hazardous road conditions. Sporadic
power outages will be a possibility where ice builds up on
powerlines and/or trees. Pipes (including sprinkler systems) will
be subject to bursting if not adequately insulated, and
hypothermia may be a possibility for those exposed and not dressed
accordingly.

* Residents should complete preparations before the coldest air
and widespread frozen precipitation begins arriving Sunday
evening. Remember the 4 P`s: pipes, people, pets and plants. In
addition, be aware of space heater and generator dangers if not
properly placed/used.

&&

.SHORT TERM [Tonight Through Monday]...

Temperatures so far today have been hovering around or slightly below
freezing across our northwest counties, mid to upper 30s central and
lower to mid 40s coast. Almost nothing has been showing up on radar,
but that will change beginning tonight as the first disturbance moves
across the area and produces frozen precipitation north (where lows
will be near or slightly below freezing) and rain to the south (where
temperatures above freezing are expected). At 9 PM, the Winter Storm
Warning begins up north, and the Winter Storm Watch begins down south.
For the most part, light accumulations are expected overnight through
much of tomorrow morning with this first system, but any accumulations
in/near the warning area will lead to hazardous conditions.

High resolution models coming in are painting a potentially very dangerous
winter weather event over at least the next 48 hours (through Monday),
and with a long period of below freezing temperatures, very dangerous
conditions look to be setting up for parts of the area Tuesday through
Thursday night (see the Long Term section below).

The stronger system begins tomorrow afternoon and peaks tomorrow night
through early Monday morning. The Winter Storm Watch is upgraded to
a Winter Storm Warning at 3 PM Sunday, and this places the entire area
under the Warning through Monday afternoon. As temperatures fall from
Sunday afternoon through Monday morning, expect to see periods of rain
mixed with freezing rain/drizzle up north that will eventually transition
to snow, and expect to see periods of rain transitioning to rain mixed
with freezing rain/drizzle that eventually could transition to snow
down south...including the beaches. High resolution models coming in
are showing the potential for 1 to 3 inches of snow north (locally
higher amounts possible) with lower amounts as you get closer to the
coast. Further to the south, freezing rain accumulations may reach
a tenth to a quarter inch. If this happens, expect to see sporadic
power outages where the buildup occurs on powerlines and/or trees.
Pipes (including sprinkler systems) will be subject to bursting if
not adequately insulated, and hypothermia may be a possibility for
those exposed and not dressed accordingly. Monday`s high temperatures
will struggle to get any warmer than the teens north and west and the
20s south and coast. A Hard Freeze Watch and a Wind Chill Watch begin
at 6 PM Monday for the entire area, and they will likely need to be
upgraded to a Warning.

You only have about one day left to prepare for this potentially historic
winter event! 42

&&

.LONG TERM [Monday Night Through Saturday]...

While the first round of winter precipitation comes to an end on
Monday afternoon, the other dangerous hazard going into the
overnight hours will be the extremely dangerous low temperatures. On
Tuesday morning, lows will be near zero in our northern counties,
around 10-15 degrees near Houston and in the upper-teens/lower 20s
along the coast. None of the winter precipitation will melt, so
travel conditions will be extremely hazardous through at least
Tuesday afternoon. This arctic air will be very frigid, and those
without the proper attire will be at risk of hypothermia if outdoors
for an extended period of time. For Tuesday, areas north of I-10
will likely remain below freezing even into the afternoon hours, so
any winter precipitation that has previously fallen will remain and
so will the hazardous travel conditions. South of I-10, temperatures
will make it into the mid-to-upper 30s and lower 40s along the
coast.

A surface coastal low begins to develop late Tuesday night/early
Wednesday morning. This will bring another round of precipitation to
the area throughout the day on Wednesday and into Thursday morning.
Model guidance is still iffy on the temperatures as far as the
freezing line goes. There is consistency that the initial surge of
moisture comes early on Wednesday when our northern counties will
still be below freezing. Forecast soundings support a freezing
rain/sleet mix initially for this area. Temperatures expected to
rise above freezing in the afternoon hours, so a transition over to
rain is anticipated during this timeframe. As far as the Wednesday
temperatures go, it`ll be close (talking a 1-2 degree difference)
for our far northern counties on if they get above freezing. GFS and
Euro are in agreement on a transition back to freezing rain going
into Wednesday night for our northern counties as temperatures begin
to fall, followed by a transition to snow on early Thursday morning
as the precipitation finally comes to an end. Overnight temperatures
for Wednesday will drop below freezing once again for most of the
area (the exception being along the coast and our far southeastern
locations). With ground temperatures likely not recovering enough,
we could have another period of hazardous travel conditions for
Wednesday night/Thursday.

This may sound like a broken record, but high temperatures on
Thursday are likely to remain below freezing once again for our
northern counties. It is a very real possibility that our northern
locations may not reach above 32 degrees until Friday. Further to
south, temperatures will make it into the upper 30s/low 40s. The
somewhat good news is that high pressure will be moving in from the
west, so we`ll see clearing skies and an end to the winter
precipitation. The mostly clear skies combined with continued CAA
with northerly winds flowing over the ice that will still be in
place to the north means we`re expecting another hard freeze for
Thursday night with temperatures down into the teens up north and in
the 20s near the Houston metro area and south. High pressure moves
off to the east on Friday and puts us into a southerly flow.
Temperatures will FINALLY get out of the 30s as we see high
temperatures back into the 40s/50s which seems rather warm in
comparison. Southerly flow continues into Saturday where we will
likely see temperatures rise into the 60s. How`s that for a
temperature swing? 26

&&

.MARINE...

Northerly winds of 20-25 knots with gusts near 30 knots continue to
persist. SCA will remain in place for all the waters through
tomorrow night as these conditions will continue to persist. Heading
into Sunday, winds will become northeasterly as a coastal low begins
to develop in the western Gulf. Wind speeds will increase to 30-35
knots with gusts over 40 knots in the timeframe of Sunday
night/Monday morning. A Gale Watch is in effect for this time period
as a result. Additionally, seas will build up to 12-13 feet offshore
and 7-8 feet nearshore. As the low pushes off to the east, strong
offshore flow returns in its wake and seas will begin to decrease
throughout the day on Monday. Another potential hazard for this
event will be freezing spray with the prolonged period of freezing
temperatures. Wind speeds will start to come down on Tuesday morning
as well. Another coastal low will spin up on Wednesday morning and
bring another period of SCA conditions as offshore winds of 20-25
knots return. 26

While technically Angleton is considered 'inland' it isn't by much, and most people don't realize how close it is to Christmas and West Bay.

Getting surge across 2004 down by 543 isn't uncommon in the right setup. Surge in Carla made it to the fairgrounds.

Blake has been consistent for 2 days. The models and now casting have been inching closer to his forecast.

We have not been above freezing in 2 days. I was out taking care of the outdoor faucets. My rain gauge was frozen. lol
