.SHORT TERM /THROUGH SATURDAY/...
Issued at 310 PM MDT Fri Aug 29 2025

Currently..

Showers and thunderstorms have developed across much of the area,
with one severe warned storm currently pushing through Las Animas
County. Satellite imagery depicts lots of cloud cover over the high
country, with mostly clear conditions over the plains. Dewpoints are
in the upper 50s and low 60s on the plains. Temperatures are in the
70s and low 80s.

Rest of Today and Tonight..

Showers and strong to severe thunderstorms are expected to continue
through much of this afternoon and into this evening. SPC
Mesoanalysis currently paints around 1500 to 2000 J/Kg of SB CAPE
over much of our plains throughout the window for convection, along
with 40 kts of effective shear. Chances for strong to severe storms
look to remain in place through this evening, especially over and
east of the I-25 corridor, where clearing is most prevalent this
hour. Subsevere thunderstorm activity will be possible through the
late evening hours, with lingering showers into the overnight hours.
Cloud cover looks to keep temperatures mild heading into tomorrow
morning. Our Severe Thunderstorm Watch over Las Animas, Baca,
Bent, Prowers, Otero, Crowley, and Kiowa counties will remain in
place through 10 PM this evening, though some counties may end
up being dropped earlier.

Tomorrow..

Our flow aloft becomes more northwesterly throughout Saturday, which
will begin to dry things out incrementally across the forecast area.
Shortwave energy and lingering surface moisture will still be
sufficient to pop off another round of afternoon showers and
thunderstorms over the region. Overall, models hint at less
instability for tomorrow, especially north of Highway 50, given the
trend towards prolonged early morning cloud cover. Shear will still
remain elevated, with generally 40kts or so expected throughout the
afternoon hours across much of the plains. Overall thinking is that
thunderstorms may be slow to get going, especially near the
mountains, given early morning cloud cover, but anything that keeps
its act together or manages to form up in areas that clear out will
have the potential to become strong to potentially severe. Main
risks with any stronger storms tomorrow will be heavy rain, small
hail, wind gusts to 55 mph, and lightning. Other than thunderstorm
chances, tomorrow`s daytime highs look to be slightly cooler than
Friday`s/today`s by just a couple of degrees, which would put highs
in the 70s over our mountain valleys, the Raton Mesa, and the higher
elevations of the Pikes Peak region, with lower 80s elsewhere on the
plains. Showers and thunderstorms are expected over the high country
as well, though storms are likely to be subsevere over our mountains.

.LONG TERM /SATURDAY NIGHT THROUGH FRIDAY/...
Issued at 308 AM MDT Fri Aug 29 2025

Upper ridge amplifies over the wrn U.S. from Sunday into early
next week, with main moisture plume suppressed south of
Colorado. Should see much less in the way of convection in the
Sun-Tue time period, though residual moisture will lead to at
least isolated afternoon showers/thunderstorms over the
mountains. Temperatures will warm slightly with less moisture
and cloud cover, and highs will rise back toward seasonal
averages through the period. Amplified upper pattern will
eventually send a cold front southward through the area,
potentially on Wed, with cooler air and moisture returning to
from late Wed into Thu. Shower and thunderstorm chances will
increase behind the front, especially over the eastern mountains
and plains, with 00z/29 deterministic run of the ECMWF
particularly aggressive on bringing back cooler air and
precipitation to the area.

.AVIATION /18Z TAFS THROUGH 18Z SATURDAY/...
Issued at 1136 AM MDT Fri Aug 29 2025

For KCOS and KPUB..Another round of showers and thunderstorms
will be possible this afternoon and this evening, mainly between
21Z and 02Z. MVFR ceilings and visibilities will be possible
during thunderstorm activity, with VFR conditions expected
outside of thunderstorm chances. Lingering showers will be
possible until 06Z, with the threat of lightning diminishing
after 02Z. Storms today will be capable of producing hail up to
1.5 inches, outflow winds gusting to 60 mph, heavy rain, and
lightning. Northerly winds and clearing skies are expected
through the rest of the overnight period.

For KALS..VFR conditions are expected throughout the forecast
period, with scattered to broken mid and upper-level cloud
cover. Winds will be light and mainly westerly during to daytime
hours, becoming easterly overnight.
