.SHORT TERM /THROUGH WEDNESDAY/...
Issued at 127 PM MDT Tue Oct 14 2025

Much drier today then this time yesterday, however showers and
thunderstorms were beginning to develop over the San Juans per KALS
doppler radar. A few other showers were noted over the far southeast
plains. Otherwise partly to mostly cloudy skies prevailed across the
region. Temps on the plains showed variability early afternoon as
temps ranged to around 60F in Monument to mid 70s over the far
eastern plains. In the valleys temps were more uniform with readings
in the U50s to lower 60s. high mtns were in the 30s and 40s.

Main concern will be the continuing threat for heavy rain in
the San Juans. Overall threat is lower today but any locally
convective showers could cause high water issues over the
saturated ground. For this reason will continue the watch
through midnight tonight. It is possible that the watch may need
to be extended or re-issued later tonight or early tomorrow as
new guidance is still continuing a local threat of continued
heavy convective showers over the San Juans tomorrow, and SPC
has the San Juans and San Luis Valley under marginal severe risk
tomorrow, and WPC has a marginal risk for excessive rain.

For the rest of the region, the best chance of showers will be along
the Sangres tomorrow with isolated showers and thunderstorms on the
plains. Max temps tomorrow should be the warmest of the week, with
mid 70s to mid 80s over the plains and near 70 Valleys. It will
rather breezy to windy tomorrow, especially over the southern
San Luis valley and the far eastern plains. /Hodanish

.LONG TERM /WEDNESDAY NIGHT THROUGH TUESDAY/...
Issued at 316 AM MDT Tue Oct 14 2025

Thursday, the main concern will be the threat of strong to
marginally severe storms over the far eastern plains during the
afternoon as the deep trough to our west pushes east. Plenty of
deep shear will be in place, but CAPE values may be somewhat
restricted.

A cold front will drop through the plains Thursday night with a
crisp cool morning expected on Friday.  Some of the mountain valleys
will drop into the upper teens to lower 20s, and we may see some
patchy frost if winds decrease quickly enough along the higher
terrain of the I-25 corridor.  Temperatures on Friday will cool
around 5 to 10 degrees from the previous day.

The weekend into early next week looks dry and seasonal with
near normal temperatures. Latest model blend shows the best
chance (20-50%) for frost or a light freeze Sunday morning along
the I-25 corridor and adjacent plains but Sat morning could
also be affected on the Palmer Divide. Warmer temperatures
return for Monday as upper ridging transitions back to southwest
flow ahead of the next approaching western U.S trough/low
pressure system. -KT

.AVIATION /06Z TAFS THROUGH 06Z THURSDAY/...
Issued at 1138 PM MDT Tue Oct 14 2025

KALS: Breezy south-southwest winds will persist for a few more hours
tonight, with low (around 30%) chances of showers at the terminal as
rain continues over the higher terrain nearby. Beyond that, breezy
south winds and cigs hovering around the high end of MVFR will last
through this forecast period. Showers are expected to move into the
valley later in the afternoon towards evening, and have included a
PROB30 for approaching thunderstorms.

KCOS: Cigs are expected to drop towards the high end of MVFR
overnight. Early Wednesday morning, mainly between 09 and 15Z,
southeast surface winds are expected to bring patchy stratus into
the area, which may impact the terminal for periods of time. VFR
conditions are expected to return by mid-morning, with gusty south
winds kicking in by 18Z. Showers and a few thunderstorms will be
possible in the evening over the Palmer Divide and Pikes Peak
Region. Showers are not currently expected at the terminal, though
one or two may possibly push east towards the end of this forecast
period. Left as VCSH for now.

KPUB: Winds will weaken overnight, becoming more variable until
later Wednesday morning. VFR conditions are expected through at
least mid-morning, with lowering cigs (still VFR) and gusty
southeast winds picking back up by afternoon.
