The radar

The Goodland radar (KGLD), 128 km from the middle of the area, began a volume at 01:27 UTC, the scan nearest the moment this went out.

The archived warnings, watches and discussions in force at that minute are drawn over the scan, this one among them.

Did it verify

Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this severe thunderstorm warning while it was in force. That is not proof nothing happened: reports are thin where few people live.

Cow counts a report within 15 km of the polygon while the warning was in force: a tornado for a tornado warning; hail of 1 inch or more, a gust of 58 mph or more or wind damage for a severe thunderstorm warning; a flash flood report for a flash flood warning.

The nearest sounding before it

Denver, CO (KDEN), launched 00:00Z, 1.4 hours before the alert went out and 174 km from the middle of its area. This is the routine balloon launch nearest before it, the air the forecaster had in hand, not a measurement taken for the alert.

What forecasters said that day

The local office's own words before this severe thunderstorm 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 severe thunderstorm warning went out at Jul 12, 3:28 PM MDT, 3 hours 57 minutes earlier.

Area forecast discussion, Jul 12, 3:28 PM MDT, 3 hours 57 minutes before

Area Forecast Discussion
National Weather Service Pueblo CO
328 PM MDT Wed Jul 12 2017

.SHORT TERM...(This evening through Thursday)
Issued at 324 PM MDT Wed Jul 12 2017

Tonight: still a risk for locally heavy rain and a couple severe
storms, mainly from the northern Sangre de Cristo Mountains across
the Pikes Peak Region. Showers and storms will spread east through
portions of the plains and a weather disturbance brushes by.
Models show the potential for locally heavy rains in those areas,
including burn scars. Flash Flood Watch will remain in effect
through a part of the evening. Some showers will likely linger
through the nighttime hours, especially across the east.

Thursday: Models show likelihood of diurnal showers and storms
with upper high overhead. Risks will be a few marginally severe
storms across the I-25 corridor and southeast plains, and flash
flooding across and near burn scars and urban areas.

.LONG TERM...(Thursday night through Wednesday)
Issued at 324 PM MDT Wed Jul 12 2017

Thursday night: weak upslope flow continues across the southeast
plains into the eastern mountains with ongoing convection mainly
across the mountains and adjacent terrain, where CAPE values are
generally around 1000 j/kg. Convection should wane through the
evening hours and perhaps linger into the overnight across and
near the higher terrain.

Friday: Upper high continues across the western half of the US.
NAM has adequate moisture for diurnal showers and storms, mainly
across the higher terrain and adjacent ground, but shows some
drier air circulating in from the north across the I-25 corridor
and plains, so coverage of rain will tend to be less.

Saturday: differences between NAM and GFS, with NAM having fairly
dry air with the upper ridge across a good part of the air, while
GFS has moisture generating showers and storm, but again mainly
mountains and adjacent high valleys and plains. Blend of models
has isolated to scattered coverage across the eastern part of the
CWA and scattered to numerous coverage western areas, so will go
with that scenario.

Sunday through Wednesday:  Upper high entrenched across the Rockies.
Diurnal showers and storms the rule, with best monsoon moisture
shunted to our south across Arizona and New Mexico.

Temperatures will be near or at seasonal norms across the area,
with 80s and 90s across the plains and I-25 corridor, 70s and 80s
high valleys and 60s and 70s mountains.

With this type of pattern, precipitation will be moving slowly,
and any stronger storms will bring the risk of locally, heavy rain
and possible flash flooding.

Additionally, while fine fuels have cured across a good part of
the area, critical fire weather conditions will not be realized
under the upper high. Lightning strikes are always an issue with
fire starts though.

&&

.AVIATION...(For the 00Z TAFS through 00Z Thursday evening)
Issued at 250 PM MDT Wed Jul 12 2017

Diurnal showers and storms for ALS, COS, and PUB. VFR conditions
are expected until storms move over sites, then MVFR conditions
will occur for a brief time along with highly variable, gusty
winds. After the the thunderstorms pass and night falls, the
surface will be moist from the fresh rainfall, so COS and PUB
should experience MVFR criteria fog conditions, clearing up in the
late morning hours.
