.UPDATE...
Issued at 807 PM MST Sat Feb 22 2025

Quiet weather night across the area with some high clouds passing
across the northern part of the state. Adjusted forecast winds
(mainly wind direction) earlier as weak north winds set up across
much of the Front Range. Winds have decreased and are transitioning
to their typical drainage direction. No additional changes were made
or are planned.

.SHORT TERM /Through Sunday/...
Issued at 202 PM MST Sat Feb 22 2025

A weak shortwave will bring an area of high clouds over Colorado
tonight. Winds will increase over the mountains, with a brief
period of wave amplification possible late tonight into early
Sunday morning. Given the marginal flow, we expect peak winds in
the 50-60 mph range in exposed higher areas, but 35-50 mph gusts
to be more common in the higher east slopes areas, with some of
that wind trickling down to the base of the foothills but at
lighter speeds. The clouds should diminish Sunday morning, though
remaining wave clouds are likely. With some enhancement to the
southwesterly winds behind the shortwave, conditions should be
pretty good to maximize heating. We nudged temperature up a
little, with highs around 60. Breezy areas near the foothills
could be a little warmer still.

.LONG TERM /Sunday night through Saturday/...
Issued at 202 PM MST Sat Feb 22 2025

The extended period looks to remain warm and generally dry as
broad ridging persists across the Western US through next weekend.

There may be a few snow showers on Sunday night as a little
moisture embedded in the west-northwesterly flow arrives, which
will linger into the first part of Monday. The continued downslope
across the lower elevations will lead to even warmer temperatures
than this weekend, with guidance in good agreement with low to mid
60s across most of the plains.

Tuesday should be warm, but windy across most of the forecast area
as a dry trough approaches. Widespread 30 to 40 mph gusts look
likely in the afternoon, with a few higher gusts across the
typical higher elevations of the Front Range mountains. Some
scattered orographic snow showers will be possible over the high
country, but any accumulation looks to be light.

A cold front is expected to pass through sometime late Tuesday,
leading to a brief cooldown for Wednesday. Temperatures should
still end up fairly close to normal (upper 40s/low 50s). Ridging
looks to quickly build back for the latter half of the week into
next weekend, with a return to above normal temperatures across
the forecast area.
