.SHORT TERM /THROUGH TONIGHT/...
Issued at 1240 AM MDT Tue Apr 21 2026

Upper ridge migrates eastward across Colorado today, with very
minor increase in mid-level moisture along the Continental
Divide this afternoon as southerly flow begins to strengthen
behind the departing ridge. Will likely see a few light
showers/sprinkles over the higher peaks along the Divide by
early evening, though any precip amounts will be light.
Unseasonably warm today at most locations, with some low 90s on
the plains. Air mass remains very dry, though winds stay
relatively light through the day, keeping fire danger limited.
Overnight, increasingly breezy as south winds ramp up, keeping
min temps rather mild at many locations.

&&

.LONG TERM /WEDNESDAY THROUGH MONDAY/...
Issued at 1240 AM MDT Tue Apr 21 2026

Warm, dry and windy on Wednesday with very high fire danger, as
upper low moves from the nrn Great Basin in wrn Wy by evening.
Strong upper jet wrapping around the south side of the low noses
into wrn Colorado by Wed evening, while at the surface lee
trough/dryline sharpens up near the KS border by mid-afternoon,
then moves quickly eastward into KS Wed evening. A few CAMs
suggest a high-based tsra possible along the dryline across ern
Prowers/Kiowa Counties mid/late afternoon, so will keep a narrow
sliver of pops along the border to account for this. If storms
develop, main threat would be wind, and at at least a low risk
of a fire start or two due to lightning. Remainder of the area
will be windy and very dry, with w-sw winds gusting 45-55 mph,
windiest San Luis Valley and in/near the Sangres. Current Red
Flag Warning covers the situation nicely for now, though will
continue to monitor for PDS warning potential in the San Luis
Valley/Fremont County/Sangres, where winds will be strongest.

Upper jet remains overhead Thu, though forecast soundings show a
pronounced weakening of mid level flow during the day, with
strongest winds well above mountain top level until late
afternoon. Surface low pressure spins up on the plains 18z-00z,
though gradient remains rather slack east of I-25 until evening.
Overall, confidence is rather low (30-40 percent) in critical
fire weather conditions, given we'll have to mix 15k-20k feet
AGL to reach stronger winds, especially on the plains. Will keep
Fire Weather Watch in place for now, as air mass will remain
very dry, and it won't take much wind for areas of critical
conditions to develop, with the greatest risk over the mountains
and along the NM border. Max temps cool 5-15 degf Thu as mid
level thermal ridge is knocked down by passing upper trough.
Weak cold front then passes Thu night, though moisture increase
behind the boundary is rather meager, keeping any shower chances
limited to mainly the central mountains and Pikes Peak region.
Breezy and continued cooler Fri, with at least some pockets of
near critical fire weather over the area once again, as we await
secondary cold front and at least a weak surge of moister air
Fri night.

Still cool and unsettled over the weekend into early next week
as series of upper waves rotates through the region, with still
a good deal of model/ensemble spread on where/when heaviest
precip will fall, Rough consensus is Sun/Sun night will have the
highest pops, though will note 00z ECMWF deterministic solution
and many of the EC ensemble members continue to keep the
heavier precip to the north, while 00z GFS leans a little more
south. Air mass will be cold enough for snow in the mountains,
with even a rain/snow mix possible across most interior valleys
and the Palmer Divide.

.AVIATION /12Z TAFS THROUGH 12Z WEDNESDAY/...

Upper level ridging in place across the Rockies will keep VFR
conditions and diurnal winds at COS, PUB and ALS over the next
