.SHORT TERM /THROUGH TONIGHT/...
Issued at 1233 AM MDT Sat May 16 2026

Today and Tonight..

Showers and outflow boundaries have mostly cleared the area as of
midnight, with only a few lingering down on our far southern border.
Temperatures are still in the 60s and 70s across the area, with
dewpoints in the 30s on the plains and teens to 20s over the high
country. We'll start out our Saturday with poor overnight moisture
recoveries, and temperatures will warm quickly as southwest flow
aloft increases over the region. Downsloping winds look to reach
gusts of 30 to 40 mph over the San Luis Valley and our eastern
mountains, and several fire weather zones that have critical fuels
remain under a Red Flag Warning for today. The central mountains,
Sangres, Wets, Fremont, Pueblo, Crowley, Otero, Las Animas, Bent,
and Baca counties are expected to see several hours of 25 mph wind
gusts and humidity values below 15% this afternoon. Daytime high
temperatures are expected to be much warmer than normal once again
as well, with mountain valleys, the Pikes Peak region, and the
southern I-25 corridor all climbing into the 80s, and the rest of
our plains warming into the 90s. Afternoon showers and thunderstorms
are expected for our northernmost areas as well, some of which may
be strong to severe. Chances for strong to severe storms will be
highest over El Paso, Kiowa, and Prowers counties. These areas are
outlined for a marginal risk for severe storms tomorrow, with
damaging winds and 1 inch hail possible.

&&

.LONG TERM /SUNDAY THROUGH FRIDAY/...
Issued at 1233 AM MDT Sat May 16 2026

Sunday..

Models try to bring a cold front south across our plains Sunday, but
for now, models hint that southwest flow will win for most of the
day. For this reason, high fire danger is expected and storms are
not. If models begin to trend towards an earlier arrival of the
front, the forecast focus towards chances for strong to severe
thunderstorms. For now though, fire weather and strong southwest
winds with gusts of 40 to 50 mph are expected for Sunday, along with
another day of much warmer than normal temperatures. Highs will be a
few degrees less than today, but still well into the upper 70s for
mountain valleys, and mid to upper 80s on the plains. Models finally
bring the front southwards across our plains after sunset when
southwest flow ebbs, which will allow for gusty north winds over
portions of the plains Sunday evening. Showers and thunderstorms may
end up forming up over the Palmer Divide on Sunday as well,
especially if the front hangs up along this area. Storms here could
be strong to severe More widespread coverage of showers and
storms will be expected over the high country, and generally
along and west of I-25, and along and north of Highway 50,
overnight Sunday behind the cold front.

Monday Onwards..

The trough axis continues to approach throughout Monday, which will
keep very gusty winds over the high country Monday morning. Models
bring the trough axis and strongest jet support for high winds
across our forecast area by late morning, and winds should begin to
weaken through the afternoon. For now, highlights are not expected,
but High Wind Watches may end up being necessary if models trend any
strong with winds late Sunday night into Monday morning, especially
over and in the lee of the eastern mountains. Light snow is also
expected over the higher peaks of the Continental Divide, with 1 to
2 inches possible over the San Juans, and 2 to 4 inches possible
over the central mountains from Sunday night through Monday night.
Showers and thunderstorms increase in coverage on Monday on the
plains as well, especially north of Highway 50. The front gets
hung up again along our southern border, which will keep
temperatures in the 80s over eastern Las Animas and Baca
counties. Both areas may see another round of critical fire
weather conditions on Monday. All other areas on our plains
should be in the 60s and 70s with continued chances for showers
and weak thunderstorms. Models finally bring the front through
more earnestly Monday night into Tuesday. Models keeps high
temperatures in the 60s and low 70s for both Tuesday and
Wednesday, with off and on chances for showers and
thunderstorms. As northwest flow weakens towards the end of the
work week, temperatures begin to climb back into the normal
range.

.AVIATION /18Z TAFS THROUGH 18Z SUNDAY/...
Issued at 1114 AM MDT Sat May 16 2026

Winds will continue to increase this afternoon from a south to
