What forecasters said that day

The local office's own words before this blowing dust 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 blowing dust warning went out at May 18, 5:43 AM MDT, 3 hours 48 minutes earlier. Its key messages:

  • Extreme fire danger is expected across our southern plains today, with southwest winds gusting 45 to 50 mph and humidity values in the single digits.
  • 50 mph winds are expected over the southern mountains and the San Luis Valley, which may lead to blowing dust over the valley, blowing snow over the mountains, and travel concerns resulting in both cases.
  • Showers will be possible north of Highway 50 and west of I-25, with thunderstorms mainly across the Pikes Peak region.
  • A Freeze Watch remains in place for El Paso and Kiowa counties tonight, and frost may be possible for other portions of the plains as well.
  • Cooler and wetter weather is expected for all areas tomorrow and Wednesday.

.SHORT TERM /THROUGH TONIGHT/...
Issued at 105 AM MDT Mon May 18 2026

For the plains..The elusive cold front has sagged back south since
sunset, and is now sitting between Springfield and Campo across Baca
County. This front and where it ends up again this afternoon will be
the driving factor in today's forecast across the plains once again.
North of the front and west of I-25, stratus has begun to develop up
against the terrain as of midnight. USAFA is reporting ceilings down
to 2,000ft, and the Colorado Springs airfield is starting to see
lower scattered decks as well. Models continue to suggest that rain
will be possible as upslope continues across the mountains/plains
interface throughout this morning. Thunderstorms will be possible
across the Pikes Peak region again this afternoon, though severe
development is not expected. That said, lots of shear will present
over the region today, so if any areas clear out and warm up,
chances for a stronger storm or two may be possible, especially over
the higher terrain of the Pikes Peak region. The main forecast
concern on our plains today though will be our high end Red Flag
Warning across our southern plains. Las Animas and Baca counties are
both included in this warning, and southern portions of Bent and
Prowers counties may see periods of critical conditions as well
depending on how far north/east the front gets shoved this
afternoon. Over these areas, single digit relative humidity values
and southwest wind gusts of 45 to 50 mph are expected. The strongest
winds and lowest humidities will be over Baca County this afternoon,
which will lead to the possibility for extreme fire behavior for any
new or existing fires today. Please use extra caution and take care
not to start a wildfire today. One last note for the plains, gusty
winds over our southeast plains may also lead to blowing dust and
hazardous travel conditions. Once the sun sets, the front *finally*
pushes itself completely southwards, allowing all areas to cool and
moisten through the overnight hours. This will put an end to fire
weather concerns for a few days. Overnight lows will be chilly in
our post frontal airmass though, and areas north of Highway 50 may
see hard freeze conditions by Tuesday morning. El Paso and Kiowa
counties are both under Freeze Watches for tonight through early
Tuesday morning, and temperatures down into the upper 20s will be
possible. Another tier of counties or two may also see the potential
for frost depending on clearing through the overnight hours.

For the high country and the San Luis Valley..Models bring the
trough axis through our southern mountains between 9 AM and Noon or
so, which will be the windiest timeframe for the San Juans, the San
Luis Valley, and the Sangres. The NBM continues to be the only
outlier suggesting high wind criteria, so have continued to trend
towards other model consensus, which keeps winds below warning
levels across the area. The San Luis Valley is likely to see gusts
upwards of 50 mph or so though, especially if any showers survive
off the mountains and help to enhance gusts coming down the terrain.
Areas of blowing dust are likely across the Valley today, especially
with any localized stronger winds from decaying showers. Over the
mountains, a quick 2 to 4 inches of wind driven snow will be
possible for the San Juans and the central mountains. Though totals
will be low, degraded visibility and hazardous travel conditions may
be possible from blowing snow, especially over mountain passes. Snow
comes to an end for both range by around midnight or so at the
latest.

&&

.LONG TERM /TUESDAY THROUGH SUNDAY/...
Issued at 105 AM MDT Mon May 18 2026

Tuesday and Wednesday..

The front is finally through us and will stay through us for Tuesday
and Wednesday. We stay in southwest flow aloft as messy troughing
sits out west. This pattern will keep temperatures cooler than
normal, and it will keep precip chances over us as well. Models
bring shortwave energy through the trough and over us on Tuesday,
which will help to develop weak showers and thunderstorms over the
high country on Tuesday afternoon, and better chances for widespread
rain on the plains overnight Tuesday and into Wednesday. Daytime
highs look to stay in the 60s both days, with decent chances for
precipitation both days.

Thursday Onwards..

Models are not in great agreement about the pattern late week
onwards, but the general consensus suggests some type of northwest
flow with a trough passing to our north. This looks to bring
temperatures back into the near normal range for Thursday and
Friday, with warmer than normal temperatures by the weekend. Chances
for showers and thunderstorms will remain in the forecast nearly
every afternoon, especially across the high country.
