What forecasters said that day

The local office's own words before this high wind warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Pueblo, CO wrote its last area forecast discussion before this high wind warning went out at Feb 20, 10:45 PM MST, 5 hours 46 minutes earlier.

1045 PM MST Mon Feb 20 2023

.SHORT TERM...(This evening through Tuesday)
Issued at 254 PM MST Mon Feb 20 2023

Key Messages:

1) Winds gradually diminish this evening and overnight

2) Breezy to windy on Tuesday, with high fire danger over the far
southeast plains

Still windy at many locations this afternoon with gusts of 35-45 kts
common, though did cancel the mountain high wind warning early as
most high elevation gusts have come down into the 50-60 kt range.
Expect winds to continue to diminish this evening and overnight as
surface pressure gradient briefly lessens and mountain wave
dissipates, though still some 30-40 kt gusts possible higher exposed
peaks of the mountains, while far eastern plains see south winds
gusting 20-30 kts by morning as pressure falls resume east of the
mountains. Still an occasional snow shower or flurry possible over
the central mountains through the night, and some blowing snow
likely, especially higher west facing slopes north of Cottonwood
Pass. Min temps held up somewhat by winds/mixing, though many
valleys may decouple enough to drop to seasonably cold readings.

On Tuesday, winds increase again through the day, especially across
the srn half of the area along the NM/OK borders, as upper jet
begins to lift northward ahead of the deepening wrn U.S. trough.
With snow melted and fuels becoming critical, have hoisted a red
flag warning for far sern portions of the plains for Tue afternoon
where wind/low RH combo is most favorable for increased fire danger.
Will have to watch areas farther back west toward Trinidad and
Pueblo for expansion of any fire highlight, as they will at least
get close to Red Flag thresholds by late afternoon. Snow will
gradually return to the Continental Divide through the day, though
steadier/heavier snow will likely hold off until evening, so no
highlight needed for the daytime hours. High temps will again soar
to well above average levels at most locations, and some near 70f
readings are possible over portions of the plains.

.LONG TERM...(Tuesday night through Monday)
Issued at 254 PM MST Mon Feb 20 2023

Models continue to be in good agreement with important minor
differences in the details. Mostly, how far south a front pushes
before stalling on the Plains Wednesday. Mountains areas will be
very windy, along with areas down along the New Mexico border and
appropriate highlights have been issued for these conditions and
will be discussed below. Beyond mid week into early next week,
differences arise with the next upper system.

Tuesday night through Wednesday night...a strong upper storm
system is forecast to drop south across the Great Basin Tuesday
night. This will spread moderate to periods of heavy snow along
the Continental Divide through the overnight hours, and persisting
into Wednesday evening. Given the southwesterly flow, snow will
be heaviest over the San Juan Range. In addition to the snow,
winds will be very strong across the higher elevations as a speed
max moves overhead. Gusts as high as 80 mph, if not stronger, are
expected over the Mountains. Over the San Juans where the snow
will be the heaviest, opted for a Blizzard Warning. Upwards to 2
feet of snow are forecast above 10 kft, with up to a foot for the
Upper Rio Grande Valley. Winds gusting in excess of 80 mph will
produce blow and drifting snow, with near white out conditions
expected for travelers over Wolf Creek Pass. Those with travel
plans through the San Juans should be prepared for very dangerous
travel conditions Tuesday night through at least Wednesday
evening.

Further north, the southwesterly flow is less orographically
favorable for heavy snowfall. Areas from the La Garita Range,
north across the Sawatch Mountains will see up to 8 inches of wind
blown snow. Wind gusts will reach near 80 mph producing very low
visibilities on area roadways. Travel will likely be very
dangerous across Monarch Pass. For the lower elevations of the
upper Arkansas Valley of Chaffee and Lake Counties, snow totals
will be less, mainly around 3 to 7 inches, if that much. There
could be quite a bit of spill over off the Sawatch Range into the
valley, and low visibilities due to very strong winds are likely.
The advisory for these lower elevations is mainly due to expected
travel impacts due to blowing snow and poor visibilities. Also
opted for Winter Weather Advisories for the higher elevations of
the Sangre de Cristo Range. Snow amounts will generally be in the
3 to 7 inch range, but winds will also be strong around 80 mph,
producing blowing snow and hazardous travel conditions.

For the San Luis Valley, strong southwesterly winds are expected
on Wednesday. Gusts in excess of 60 mph are likely for the
southern portion of the valley, and a High Wind Watch has been
issued. Snow showers will also be possible, and the strong winds
will likely produce areas of blowing snow and poor visibilities.
In addition to the wind driven snow, sounding profiles indicate
the potential for snow squalls, which would further produce poor
visibilities on area highways.

For the Plains...much will depend on where a cold front ends up.
The GFS is most robust with the front, dropping it south along the
I-25 corridor, and east, south of Highway 50 through Wednesday
afternoon. The NAM is least aggressive with the front, stalling it
on the Palmer Divide, and keeping it just north of the CWA. The
ECMWF and Canadian runs are in the middle, with the front hovering
from the Palmer Divide to just south of Lamar. With these model
differences, went with the ECMWF and Canadian solutions.

Temperatures over the Palmer Divide to just south of Lamar will be
cold, with 30s through the afternoon. South of the front will be
warm, with mid to upper 50s. In addition to warm conditions,
strong westerly winds are expected over Las Animas and Baca
Counties and a High Wind Watch has been issued. Winds could gust
near 60 mph. Humidity values look to remain just elevated enough,
falling to around 20 percent, so did not issue any fire weather
highlights for Wednesday afternoon. Those with outdoor burning
activities planned should postpone them until another day based on
the strong winds.

As for precipitation, snow is expected over the Palmer Divide.
Snow accumulations of 1 to 4 inches are expected. Winds will not
be quite as strong with gusts near 30 mph possible. How far south
the precipitation makes it is the big question, and will depend on
where the frontal boundary ends up. The GFS with its further
south frontal position brings colder air south, and better snow
chances into the Highway 50 corridor. The north NAM is dry south
of the Palmer Divide. The ECMWF and Canadian, along with the NBM
guidance and WPC coordination, wraps a bit of rain and snow south
into the Pueblo area, with all snow by Wednesday late afternoon
and evening as colder air filters into place. Snow accumulations
look minor, from Pueblo, northeast to Kiowa County, with less than
a half inch possible. If the GFS solution comes into play,
slightly higher snow amounts may be possible. Snow and winds
should dissipate Wednesday night into Thursday morning. Overnight
lows Wednesday night will fall into the single digits to low teens
across the Plains.

Thursday through Monday...the upper system will continue to shift
east away from the area, with broad southwesterly flow filling in
across southern Colorado. This will lead to a gradual warming
trend through the weekend, with highs warming from the 30s and 40s
on Thursday, into the upper 50s to lower 60s for the weekend.
Periods of light snow are expected along the Continental Divide
through the weekend. The next upper storm system will move across
the Desert Southwest early next week, bringing another round of
snow to the Mountains, and possibly the Plains.  Mozley

.AVIATION...(For the 06Z TAFS through 06Z Tuesday night)
Issued at 1040 PM MST Mon Feb 20 2023

VFR conditions and dry weather are expected this forecast period,
with increasing mid to high level cloud cover very late. Lighter
winds are currently in place and will likely continue for much of
the morning. Strengthening southwest winds/gusts will occur at
all sites by midday into the early afternoon. Made little changes
to this forecast, though do think lighter easterly winds could be
in place at PUB and COS a little longer into the afternoon. Once
again, made little changes, but later forecasts will need to
monitor the timing of the strong west winds later today.

This hazardous weather outlook is for portions of central...east
central...south central and southeast Colorado.

.DAY ONE...Today and Tonight

Damaging wind gusts will continue in and near the central and
southeast mountains today with the strongest gusts along the east
facing slopes.  Gusts to around 75 mph will be possible across the
higher areas with gusts to 50 to 60 mph spreading into the adjacent
lower elevations.  Winds will gradually decrease this evening.

Snow will spread into the Continental Divide again today with up to
an inch of additional snow across the higher peaks north of
Cottonwood Pass.  Strong northwest winds will cause areas of blowing
and drifting snow to continue across the higher peaks and passes.

.DAYS TWO THROUGH SEVEN...Tuesday through Sunday

Breezy winds are expected across the area on Tuesday, with winds
becoming strong and potentially damaging on Wednesday. Crosswinds
may result in travel impacts. Mountain snow will also begin
Tuesday, increasing into Wednesday and Thursday, with heavy
accumulations possible over most of our mountains. Lighter amounts
may also spread to the adjacent lower elevations. Where snow
accumulates, blowing snow associated with the strong winds will
cause visibility issues and dangerous travel conditions.

Generally unsettled weather will continue through next weekend.

.SPOTTER INFORMATION STATEMENT...

Weather conditions that meet reporting criteria for spotters will
be likely over portions of the region.
