.SHORT TERM /THROUGH MONDAY/...
Issued at 211 PM MDT Sun Oct 5 2025

Tonight: Sunday night brings mild and cloudy conditions to the
plains, with dry and cool conditions elsewhere. Southwesterly flow
along the base of a positively tilted trough will be in place over
south central and southeastern Colorado. While this flow will bring
modest orographic forcing, no major forcing is expected. Along with
that, only modest moisture will be in place as the southwesterly
flow persist over the area. With no strong forcing and meager
moisture, dry conditions are expected for the valleys and mountains,
though some isolated showers will remain possible along the central
mountains where orographics will be slightly increased. As for the
plains, a slightly wetter period is anticipated. This pattern will
shove a cold front southward this evening, and surface winds will
become easterly and upslope after its passage. With saturated low
levels, and weak upsloping, spritzy light rain showers are likely
across the plains overnight. In addition, winds will be breezy
across the plains after FROPA, with wind gusts around 20-30 mph,
with light winds around and less than 10 mph elsewhere. Outside of
all of that, cloudy conditions and mild temperatures are anticipated
for the plains, with clear and cold conditions for the valleys and
mountains. Looking at temperatures, the plains will remain slightly
above seasonal lows values due to the cloud cover, with temperatures
falling into the mid 40s. As for the for the valleys and mountains,
temperatures will be more seasonal and drop into the 20s to low 30s.

Tomorrow: For Monday, not much change from Sunday night, with cloudy
and showery conditions for the plains and dry and warmer elsewhere.
Southwesterly flow along the base of a trough will remain in place,
bringing modest orographic forcing, though no major synoptic
forcing. Along with that, moisture content will remain low given the
continued southwesterly flow. Given all of this, dry conditions are
anticipated for the mountains and valleys. Then for the plains, a
slightly wetter period is expected. Surface winds will remain
easterly behind the Sunday evening cold front, allowing for
persistent, though weak, upsloping into the terrain. With low levels
remaining saturated, and meager surface upsloping, another period of
light drizzly rain showers is anticipated for plains. Beyond all of
that, the plains will remain cloudy throughout the day with
relatively light winds around 10 mph, with mostly clear and breezy
conditions for the valleys and mountains. As for temperatures, the
plains are expected to remain below seasonal high values given the
cloud cover and frontal passage, with highs in the mid 50s to low
60s. Looking at the mountains and valleys, the valleys will warm
into the 60s to low 70s, with the mountains rising into the 40s and
50s.

.LONG TERM /MONDAY NIGHT THROUGH SATURDAY/...
Issued at 306 AM MDT Sun Oct 5 2025

Monday night winds will be more upslope across the plains and low
clouds and especially fog may be more widespread. Dense fog could
occur over parts of the Pikes Peak Region (Monument Hill). Lift will
be a bit better over the region and some light showers will be
possible across the plains Monday night into Tuesday.

Tuesday will continue to be cool with lesser clouds as the day wears
on. Expect mainly 60s plains and around 70 larger valleys.

For Wednesday into the weekend, ridging builds over the region and
it will warm up quickly once again. The big unknown for the upcoming
weekend is a tropical cyclone (or the moisture associated with one)
will possibly impact the region, especially in the mountains. we
will have to wait and see how this plays out. In the meantime, Wed
through Friday should be mainly dry, with best chance of some
showers in the mountains.

Beyond next week looks quite cool. /Hodanish

.AVIATION /18Z TAFS THROUGH 18Z MONDAY/...
Issued at 1142 AM MDT Sun Oct 5 2025

KCOS and KPUB: VFR conditions are expected through this afternoon,
with MVFR conditions rapidly developing this evening as clouds lower
and increase. For winds, gusty easterly to southeasterly winds
are expected this afternoon at both TAF sites, with gusts around
25 knots. Winds will take on a more northeasterly component
during the evening hours as a cold front pushes southward, with
winds steadily weakening behind that front during the overnight
hours. In addition to the frontal passage, clouds will quickly
start to lower and increase in coverage during the evening and
overnight hours, with MVFR ceilings expected. Along with all of
that, there may be pockets of light drizzle/rain overnight given
upsloping winds and saturated low levels, though confidence in
any impacts to the TAF sites is low at this time.

KALS: VFR conditions are expected over the next 24 hours. Gusty
winds to around 20 knots are expected this afternoon, though will
lessen overnight and become more light and variable by tomorrow
morning. There may be a period of increased easterly to
southeasterly winds this evening as cold air spills over and through
La Veta Pass and into the San Luis Valley. Otherwise, dry conditions
with relatively clear skies are anticipated.
