What forecasters said that day

The local office's own words before this winter weather advisory 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 winter weather advisory went out at Mar 15, 3:16 PM MDT, 6 hours 20 minutes earlier.

Area forecast discussion, Mar 15, 3:16 PM MDT, 6 hours 20 minutes before
Area Forecast Discussion
National Weather Service Pueblo CO
316 PM MDT Mon Mar 15 2021

.SHORT TERM...(This evening through Tuesday)
Issued at 246 PM MDT Mon Mar 15 2021

Shortwave ridging over the area today will translate eastward as the
next upper low moves into central New Mexico on Tuesday.  Tonight
and tomorrow morning will be a transition period across southern
Colorado.  Skies will be relatively clear, except for some scattered
high clouds spreading in late in the period.  With the snow cover
temperatures will cool quickly after sundown and did not stray far
from guidance/model blends.  Some isolated snow showers will be
possible along the Continental Divide overnight, but accumulations
will be spotty and light.

As the upper low advances eastward into eastern AZ by mid day we
will start to see snow spread into the Continental Divide and
southwest mountains through the morning as area of difluence aloft
moves overhead. Precipitation then expands eastward into the Sangre
De Cristo mountains and southern I-25 corridor as the surface low
deepens over NE NW in response.  Mid level winds increase to around
20 kts from the east which is a good upslope component for the
southeast mountains and there will likely be some spill over into
the San Luis Valley late in the period.  As for precipitation type,
temperatures will be warm starting out with mainly rain across the
lower elevations along and east of the I-25 corridor.  Focus through
the afternoon will be mainly south of highway 50 with some question
as to the northern extent as some models are a tad farther south
than others with the more compact upper low.  Started Winter Storm
Watches at 18z for now with mountain areas likely to start sooner.
Lower elevations may not see a switch over to snow along the I-25
corridor until closer to 00z Wed so timing will need to be refined
as the event gets closer.  Overall looks like a compact fast moving
storm with main impacts in the medium ranges. See discussion
below.

.LONG TERM...(Tuesday night through Monday)
Issued at 246 PM MDT Mon Mar 15 2021

Overall, there is decent agreement through the work week, with
differences in the operational solutions and ensemble spreads
increase. The southern portion of the state will be impacted by a
storm system through Wednesday, clearing for the later part of the
week. Another storm system will be possible next weekend.

Tuesday night through Wednesday...a compact, intense upper low is
forecast to move across central New Mexico, and eject into the
Texas Panhandle Tuesday night into Wednesday morning. A deep layer
of easterly, upslope flow is forecast to develop Tuesday evening
over the southern half of the Eastern Plains and peak through the
overnight hours. This will lead to a period of heavy snow,
initially along the Sangre de Cristo and Wet Mountains, and spread
east along the New Mexico border over Las Animas and Baca Counties
through Wednesday morning. Winter Storm Watches have been issued
for the Eastern Mountains and New Mexico border region. Snow will
be heaviest over the southern Sangre de Cristo Range, into the
Raton Mesa area. One to 2 feet of snow are possible from Tuesday
night, through Wednesday early afternoon. East of Las Animas and
Baca Counties, snowfall totals will be dependent on change over
from rain to snow. Current model sounding analysis indicates a
change over to snow around 9 PM Tuesday. This area will likely see
at least 4 to 8 inches of wet snow. In addition to the snow,
strong winds are expected by Wednesday morning behind a cold
front. Wind gusts in excess of 50 mph are possible, which will
likely produce blowing snow and reduced visibilities, especially
along Highway 160.

The areas of most uncertainty, will be the San Juan Mountains,
San Luis Valley and Fremont County. Given the deep upslope flow,
the potential exists for several hours heavier snowfall along the
western edge of the Valley. Central Fremont County may end up
doing pretty well too, given the deep upslope flow expected. These
areas will likely see 2 to 4 inches, with locally higher amounts
possible. A Winter Weather Advisory may be needed as confidence
grows.

For the rest of the Plains, snow will also be possible. Snowfall
amounts of less than 3 inches are expected. The main issue will be
the strong winds, with gusts near 40 mph possible.

On Thursday and Friday, an upper level ridge will build over the
area bringing warm, dry, and relatively sunny conditions to the
whole CWA. Over the lower elevations, expecting temps to be in the
lower to upper 50s both days. Over higher elevations, temps should
stay much colder in the 20s.

Saturday into Monday...both the GFS and ECMWF have an upper trough
impacting southern Colorado over the weekend. Details are a bit
fuzzy at this point in regards to timing and storm track. The GFS
is progressive and faster, while the ECMWF is slower and less
deep. Mountain snow will definitely be likely, but whether it will
spread across the Plains remains in question. If precipitation
does make it into the Plains, Sunday into Monday look like the
most likely time period. Mozley

.AVIATION...(For the 00Z TAFS through 00Z Tuesday evening)
Issued at 246 PM MDT Mon Mar 15 2021

VFR conditions will continue this evening with diurnally driven
winds under 15 kts expected at all three terminals. There is a
chance for some patchy ground fog to develop at KALS due to light
winds and saturation of the low levels due to melting snow today.
Have introduced a short window for MVFR fog early Tuesday morning
but it is possible that cigs and vis could be IFR or lower. Will see
some VFR cigs spread into all three terminals on Tuesday,
particularly in afternoon as the storm system moves in. Cigs will
continue to drop Tuesday afternoon and night for all three terminals
as precipitation spreads in from the south. Most affected will be
KALS with the potential for around 3 inches of snow possible.  KCOS
and KPUB will see lesser amounts in the 1 to 2 inch range. -KT
