.SHORT TERM /THROUGH WEDNESDAY NIGHT/...
Issued at 106 PM MDT Tue Apr 21 2026

Rest of Today and Tonight..

Warmer than normal temperatures are present this afternoon. Relative
humidity values are very low, generally in the single digit to low
teens range. Winds are below critical thresholds this afternoon
though. Some very spotty showers will be possible over the San Juans
and the central mountains this afternoon and early this evening, but
appreciable moisture is not expected. Overnight low temperatures
will be much warmer than normal with our incoming trough and
increasing southwest flow over the region. Most of our plains looks
to only cool into the middle and upper 40s, with 50s likely over the
banana belt region where downsloping will be strongest.

Tomorrow..

A Particularly Dangerous Situation Red Flag Warning is expected for
Wednesday across the San Luis Valley, the central mountains, and the
Sangre de Cristos (fire weather zones 220, 224, and 225)... Models
have kept the incoming trough a bit to our north, with strongest jet
support for high winds located over northwest Colorado and the Great
Basin. High wind potential over southern Colorado will be equally as
terrain driven as jet driven, with strongest winds expected over the
San Luis Valley, the Sangres, and the central mountains. A High Wind
Warning has been issued for northern and central portions of the San
Luis Valley, where gusts to 60 mph will be possible. The San Luis
Valley, the central mountains, and the Sangres are also expected to
see Particularly Dangerous Situation Red Flag conditions tomorrow,
with single digit relative humidity values coupling with these very
strong winds and warmer than normal temperatures. Highest winds and
lowest rh values are expected to coincide in the valleys of these
zones, over the Upper Arkansas River Valley, the Wet Mountain
Valley, and of course, the San Luis Valley. Blowing dust will also
be a concern in the San Luis Valley, and could be a concern on our
plains as well.

Winds will not be as strong on the plains given jet placement, but
Red Flag criteria and wind gusts to around 35 or 40 mph are still
expected across our lower elevation locations. Temperatures of
around 15 to 20 degrees warmer than normal are expected, though all
three of our climate sites are currently forecast to remain around 4
to 6 degrees below standing records. Highs look to climb into the
70s over mountain valleys, with 80s and low 90s on the plains. Winds
remain elevated well into the overnight hours, especially over the
high country, which keeps tomorrow's Red Flag Warning in place
through midnight. Continued overnight mixing will keep overnight
moisture recoveries poor.

.LONG TERM /THURSDAY THROUGH TUESDAY/...
Issued at 106 PM MDT Tue Apr 21 2026

Thursday..

Mid-level flow weakens heading into Thursday, and temperatures will
be several degrees cooler as well. That said, most of the area still
looks to meet critical fire weather conditions on Thursday afternoon
for several hours, despite a marked improvement from tomorrow's
expected conditions. For now, have kept Thursday's Fire Weather
Watch in place as is, and will continue to monitor forecast changes
and any trends that could dictate changes for Thursday. Other than
potential fire weather concerns, expect temperatures in the 60s for
mountain valleys, with 70s and low 80s on the plains. Light snow
showers will be possible as well, mainly over the central mountains,
though a few flakes or rain drops may also be possible over the
higher terrain of the Pikes Peak region.

Friday Onwards..

Winds remain elevated on Friday as an upper low sits over the
northern plains. Westerly winds gusting over 25 mph look to remain
possible over much of the region, along with continued low relative
humidity values. Another day of critical weather conditions looks
likely for Friday, though highlights have not been issued quite yet.
Flow aloft weakens on Saturday, and eventually transitions to
southwest flow by Sunday. A few weak disturbances look to move
across the region through the weekend, bringing chances for snow to
the high country, and showers and thunderstorms to the plains if the
trend persists. Temperatures look to remain cooler, with highs near
normal and into the 70s on the plains. Another ridge looks to build
over the region from Tuesday onwards.

.AVIATION /06Z TAFS THROUGH 06Z THURSDAY/...
Issued at 1054 PM MDT Tue Apr 21 2026

KCOS, KPUB, and KALS: VFR conditions are expected over the next 24
hours. Winds will remain relatively light, less than 10 knots,
overnight and into early tomorrow morning. By mid to late morning,
winds will start to increase in magnitude as diurnal mixing
develops, and peak during the afternoon hours, with gusts up to 40
knots possible, particularly for KALS. In addition, blowing dust may
also be possible tomorrow afternoon as the strongest winds
materialize, which could quickly drop visibility conditions.
Otherwise, dry conditions with pockets of high level clouds
continue.
