What forecasters said that day

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

NWS Denver/Boulder, CO wrote its last area forecast discussion before this wind chill warning went out at Feb 22, 11:18 AM MST, 3 hours 27 minutes earlier.

Area forecast discussion, Feb 22, 11:18 AM MST, 3 hours 27 minutes before
Area Forecast Discussion
National Weather Service Denver/Boulder CO
1118 AM MST Wed Feb 22 2023

.UPDATE...
Issued at 939 AM MST Wed Feb 22 2023

The overall forecast picture hasn't changed much since the
previous discussion. The initial burst of snow this morning has
generally brought a few inches of snow to most of the foothills
and 1-3 inches for most of the urban corridor west of I-25, with
totals dropping off quickly to the east. Light snow showers are
currently lingering across most of the area and should continue
through the afternoon hours. This has generally been supported by
shallow NE upslope flow (~10kt to 7.5kft MSL) along with some
additional forcing from the nearby upper level jet.

A second "wave" or burst of moderate to briefly heavy snow still
looks likely later today... sometime during the early/mid
afternoon hours. Upstream observations in west/southwest Colorado
have been impressive, and hi-res guidance is generally in good
agreement on the evolution of this feature. There should also be
increasing support aloft due to increasing PVA as the 500mb
shortwave pivots through the region. A quick inch or two still
looks pretty likely across the Denver metro, with heavier amounts
possible across Boulder and Larimer counties.

Have made a few adjustments to the forecast this morning. The
first was to drastically adjust hourly/MaxT today as it feels very
unlikely that any portion of the plains will see any warming
today. Also attempted to adjust PoPs for this afternoon/evening
along with some minor updates to the rest of the winter wx grids.

&&

.SHORT TERM...(Today and tonight)
Issued at 401 AM MST Wed Feb 22 2023

A few changes in the short-term to snowfall amounts and temperatures
this morning. Without much forcing, light snowfall has spread
mainly from the mountains to the I-25 corridor. Prepare for icy
and snow covered roads during the morning and evening commutes.
Ongoing snowfall will continue for most of the region and should
finally extended to the far eastern plains through Wednesday
evening. Our area persists under northerly flow thanks to the cold
front for the plains and south to southwesterly flow for the
higher terrain. Cold arctic air stays in place along with
overcast skies which will keep afternoon highs near the mid teens
to mid 20s for all areas.

NAMNEST soundings indicate an upper level inversion steady
throughout the plains. Additionally, model guidance, such as the
NAM/GFS, highlights significant dry air in the 500-700mb layer
which could lead to decrease in snowfall development. It is
possible expected snowfall amounts could be on the low end but the
afternoon shortwave may produce additional snow accumulations
through snow bands especially along the I-25 corridor. As the
upper level trough pushes north, there will be an increase in
northerly winds producing wind gusts up to With the combination of
cold temperatures and gusty winds, wind chill values will range
from -12 to -20 across the region. Keeping Wind Chill Advisories
covering the plains through Thursday morning.

.LONG TERM...(Thursday through Tuesday)
Issued at 401 AM MST Wed Feb 22 2023

The flow aloft will become more southwesterly on Thu as a stg storm
system is over the Pacific NW.  Cross-sections show an increase in
moisture across the mtns by aftn with lapse rates around 8 c/km.
Thus should see an increase in snow shower activity especially north
of I-70.  Over nern CO, it will remain very cold in most areas with
aftn highs in the teens. The only exception would be over portions
of the Palmer Divide where southerly low level flow may allow for
highs to rise into the 20's.

For Thu night, a stg upper level jet will be over the area with
cross-sections showing some potential for banded areas of light
snow to develop, from Denver east northeast across portions of
the plains. Overall confidence isn't real high so will keep snow
chances on the lower side for now. In the mtns, will continue to
see orographic snow showers as well especially north of I-70 with
some potential for heavier bands due to position of the upper
level jet.

On Fri, SW flow aloft will continue with decent lapse rates. Cross-
sections show enough moisture for more orographic snow showers in
the mtns. Across nern CO, will begin to see moderation in temps
as readings rise into 35 to 40 degree range around Denver. However
further east over the plains readings stay in the 25 to 30 degree
range.

By Sat, drier air will spread into the area in WSW flow aloft as an
upper level storm system is located over srn California. Thus
should see an end to snow in the mtns. Across the plains, a sfc
lee trough will intensify along the front range which will allow
for warmer temps. Highs will range from the lower to mid 50s
around Denver with 40's across the plains.

Looking ahead to Sat night and Sun, the storm system over srn
California will move rapidly east northeast and affect the area Sun
aftn into Sun night.  This system will bring another good chc of
snow to the mtns.  Across nern CO, there will be a chance of showers
as it move across.  Highs across the plains will range from the
upper 40s to upper 50's.

On Mon, zonal flow aloft will be over the area.  Cross-sections show
limited moisture in the flow so expect mainly dry conditions. Winds
will be rather gusty as from the mtns across the plains.

&&

.AVIATION...(For the 18Z TAFS through 18Z Thursday afternoon)
Issued at 1103 AM MST Wed Feb 22 2023

Light snow showers should continue on and off through the
afternoon and evening hours. Ceilings are well established between
015-020 and should be fairly steady over the next several hours.
A burst or two of heavier snow... along with a reduction of
visibility... is expected this afternoon sometime after 20z. As
this snow moves through, IFR ceilings/visibilities are likely with
brief LIFR visibilities possible. Conditions should improve
overnight with the low cloud deck scattering out. VFR is forecast
after 06z though there is a chance that MVFR cigs continue a bit
longer than forecast. VFR conditions are forecast tomorrow, though
lower ceilings may develop after 18z Thursday afternoon.
