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 Nov 15, 10:39 PM MST, 1 hour 51 minutes earlier.

.SHORT TERM...(This evening through Thursday)
Issued at 331 PM MST Wed Nov 15 2017

...Winds on the increase again with elevated fire danger along
portions of the I-25 corridor and valleys...

Much cooler temperatures in place today behind yesterday's cold
front with readings running much closer to climo across the plains.
Temperatures are still running above normal farther west,
particularly at KALS.   Westerly flow aloft will strengthen
overnight as the upper trof moves into the western U.S. Surface lee
trof redevelops which should keep min temperatures on the warm side
across the lower eastern slopes of the southeast mountains as
westerly winds start to kick up again.

As the upper trof approaches on Thursday, strong westerly winds
will mix down into the lower elevations by afternoon.  Strongest
gusts are expected to stay confined to the mountain areas. However,
gusts to around 25 to 30 mph will spread eastward through gaps into
portions of the I-25 corridor counties.  Thus locations in the usual
windy spots like around Walsenburg, Fort Carson and north of
Colorado Springs will start to see breezy winds during the
afternoon.  Gusts across the higher mountains will increase to
around 50 mph by afternoon while gusts to 35 to 40 mph spread into
the adjacent valleys. This will start to raise fire weather concerns
for these areas, however latest fuels status still indicates fuels
are not critical across zone 222 (Fremont county) where conditions
are most likely to materialize.  Given Huerfano county also saw a
nice band of snow with the last snow event, this area is also not
likely not critical. So no fire weather highlights anticipated. Dew
points will also be gradually increasing through the day, especially
western portions of these areas as moisture starts to spread in
ahead of the incoming system, so it will be tough to make the 3 hour
window for critical fire weather conditions as well. Otherwise,
temperatures tomorrow should jump back up into the 70s for the
plains, 50s and 60s for the lower mountain and valley locations.,
and a mix of 30s and 40s for the higher peaks. Looks like record
highs for Thursday will be safe though it will be very warm for
November standards.

.LONG TERM...(Thursday night through Wednesday)
Issued at 331 PM MST Wed Nov 15 2017

Thursday night through Friday...A strong upper system will cross the
Pacific NW Thu night through Friday morning, then will sweep across
the Rockies Friday with the trough axis finally exiting eastern CO
early sat morning. A very tight pressure gradient will produce
strong gusty winds across the higher elevations and adjacent plains,
on top of a prolonged period of snow for the mts with a focus on the
Continental Divide. Therefore, went ahead and issued a winter storm
watch for snow and blowing snow for portions of the Continental
Divide from 06z Fri through 12z Sat, for total snow amounts of up to
18 inches possible by early Sat morning. In addition, though wind
speeds will be strong along the I-25 corridor and eastern plains Fri
morning and afternoon prior to the trough axis swinging across, the
highest wind speeds at this time are expected across Huerfano and
Las Animas Counties, near the CO/NM state line. Went ahead and
issued a high wind watch for those areas Fri morning and aftn for
wind gusts of around 60 mph.

Saturday through Monday...The upper trough axis swings across the SE
corner of the state Sat morning, with just a few lingering showers
over the E mts early Sat morning. Sat looks to be the coldest day of
the extended period, with highs only forecast to reach the 40s to
around 50F. Otherwise, dry W-NW flow across the region is expected
with temps then climbing into the 50s to around 60F on Sun and Mon.

Tuesday and Wednesday...Long range models are at odds with what
happens starting Tue across Colorado. solutions vary from an upper
closed low sweeping across the desert Sw, to a shortwave crossing
the northern Rockies bringing snow to the northern half of Colorado.
For now will stick with what the extended procedure provided, which
is an isolated chance for some snow across the higher elevations,
and seasonable max temps with readings in the 50s to near 60F for
both days. Moore

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

.DAY ONE...Today and Tonight

No hazardous weather is expected at this time.

.DAYS TWO THROUGH SEVEN...Thursday through Tuesday

Active weather will move through southern Colorado late Thursday
through Friday night.  A strong Pacific weather system will bring
snow, blowing snow and poor visibilities to the Continental Divide
from late Thursday night through Friday evening.  Snow accumulations
of 6 to 12 inches with locally higher amounts will be possible along
the Continental Divide from Monarch Pass northward. South of Monarch
Pass, accumulations of 4 to 8 inches with locally higher amounts
will be possible.  Shadowed by the Continental Divide, the eastern
mountains will only see local amounts of 1 to 3 inches.  Winds
gusting to around 60 mph will cause widespread blowing snow and poor
visibilities through the mountain passes.

Elsewhere, the main concerns with this system will be high winds and
elevated fire danger.  Winds will start to increase Thursday and
Thursday night but they will really be strong Friday and Friday
night. Gusts to around 60 mph will be possible. Although humidities
will not be low enough to require fire weather highlights, the
combination of strong winds, dry fuels and little to no
precipitation with result in high fire danger. Outdoor burning or
any other activity that could start a wildfire should be postponed
during the Thursday through Friday time frame.

.SPOTTER INFORMATION STATEMENT...

Weather spotters will not be needed today or tonight.
