What forecasters said that day

The local office's own words before this winter storm 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 winter storm warning went out at Mar 5, 10:40 PM MST, 5 hours 18 minutes earlier.

Area forecast discussion, Mar 5, 10:40 PM MST, 5 hours 18 minutes before
Area Forecast Discussion
National Weather Service Pueblo CO
1040 PM MST Tue Mar 5 2019

.SHORT TERM...(This evening through Wednesday)
Issued at 247 PM MST Tue Mar 5 2019

Upper ridge over the Rockies today, bringing warmer temps to most
locations, with interior valleys and a few mountain locations back
above freezing as of 2 pm. Ridge drifts east overnight, allowing
winds to increase over most higher terrain and lee slopes, though
doesn't appear to be enough of a mountain wave for damaging winds
and will keep most gusts around 50 kts or less. Coldest overnight
lows will be over the far ern plains where cold air mass is slowest
to retreat, while downslope warmed east slopes stay milder than the
past few nights. Continental Divide will see a few snow showers
break out after 06z as Pacific moisture fetch reaches Colorado,
though amounts through sunrise Wed should be light. On Wednesday,
moisture continues to flow toward the Continental Divide through the
day, though with upper wave hanging back toward the Great Basin
until evening and warm mid level temps, suspect snowfall will be
limited to higher elevations along the Divide through the day. Small
CAPE (50-150 J/KG) and Lifted Indices approaching zero suggest
convective nature to precip, and a lightning strike or two may be
possible over the peaks north of Monarch Pass in the afternoon. Will
convert winter storm watch to an advisory for highest Divide zones,
as snow begins to accumulate by late afternoon. Farther east,
downslope wly winds should warm eastern slopes and the I-25
corridor, while weak boundary backs wwd across the plains, keeping
max temps across portions of the lower Ark Valley cold once again.
In general, blended guidance looks ok for high temps, though made
some small downward adjustments at a few locations based on residual
snow cover.

.LONG TERM...(Wednesday night through Tuesday)
Issued at 247 PM MST Tue Mar 5 2019

Models in general agreement through the extended period with
slight differences into early next week. Ensemble spreads
become modest by late in the weekend with decent forecast
confidence.

Wednesday night through Thursday...a series of quick moving upper
level disturbances will move across the area during this period.
Winds will be the primary concern Wednesday night into Thursday
morning, especially across the mountains, spreading east into the
Plains Thursday morning. Mountain wind speeds will gust in the 50
to 60 mph range Wednesday night and through the day on Thursday.
not the best set up for downslope winds, however, a few wind gusts
are expected to spread across the lower elevations of the southern
I-25 corridor by Thursday morning. Temperatures will be tricky
with mid slopes over the Eastern Mountains and along the I-25
corridor remaining in the 40s and lower 50s.

For Thursday, mixing and gusty winds will allow for temperatures
to rise into the 50s and perhaps a few low 60s across much of the
region. The exception will be the far Eastern Plains out near the
Kansas border, where a weak boundary will back westward into our
eastern counties. This will likely lead to areas of drizzle and
fog during the late afternoon and overnight hours.

As far as snow is concerned, ongoing light to moderate snow will
continue along the Continental Divide through the period.

Friday into Saturday...a strong upper level trough is forecast to
move across the area. Winds will remain gusty across the region
and push the cold air back into Kansas Friday afternoon. Snow will
also increase along the Continental Divide Friday into Saturday
with moderate to heavy snow expected. A cold front will drop south
across the Plains Friday night with a period of light to moderate
snow possible over the lower elevations. Temperatures will remain
warm on Friday across the Plains due to the expected mixing.
Behind the front, temperatures will be cooler on Plains by about
10 to 15 degrees. Winds will subside by Saturday evening as the
upper system moves off to the east.

Sunday into Tuesday...weak high pressure will move across the
area on Sunday ahead of the next approaching storm system by
Tuesday. After a brief lull in activity on Sunday, snow will
increase along the Continental Divide by Monday. By Tuesday, the
upper storm system will track east into the Desert Southwest with
a period of heavy precipitation expected to lift north across the
region. Temperatures and atmospheric profiles are a bit warm for
snow across the Plains, which will likely see rain. Of course,
much depends on where the upper storm system tracks and where it
cuts off, but overall there appears to be a decent period of heavy
rainfall across the Plains.  Mozley
