.SHORT TERM /THROUGH TUESDAY NIGHT/...
Issued at 223 PM MST Mon Nov 17 2025

The low pressure system responsible for yesterday and today`s
precipitation currently sits near the Colorado/Wyoming/Nebraska
border and will continue to propagate east/northeast throughout
the rest of the day. This means that the coverage of valley rain
and mountain is decreasing across the forecast area with areas
along and north of I-70 seeing the highest potential for
precipitation continuing this evening. While the center of the
low has moved east of the local area, wrap around moisture
continues to favor the northern Divide mountains resulting in
light snow showers through the evening hours with little, if
any, additional accumulation expected overnight.

Seasonal temperature highlight tomorrow`s forecast with dry
conditions for most. That being said, southwesterly flow aloft
will begin to usher in the next round of moisture to the Four
Corners region tomorrow. This moisture in tandem with upslope
flow may be enough to support isolated to scattered showers
across eastern Utah and into parts of southwest Colorado, but
limited forcing will keep most locales dry. If it does rain
(valleys) or snow (mountains), minimal impacts are expected.

.LONG TERM /WEDNESDAY THROUGH MONDAY/...
Issued at 223 PM MST Mon Nov 17 2025

A low pressure system over the Desert Southwest will open up
and looks to track northeastward across the Four Corners
Wednesday evening into Thursday. Models haven`t been the most
consistent in terms of the evolution of this low and track but
it does at least look like weather remains unsettled through the
end of the week. Beyond this, yet another closed low looks to
move down the west coast behind this disturbance and settles
over the Desert Southwest this coming weekend. Models differ on
the exact track of this system so low confidence on the details
at this time. The GFS has this low tracking across the area
Sunday into Monday as an open trough, while the ECMWF takes this
low far enough south to result in minimal impact for our CWA.
Would like to see better run to run consistency before
discussing details on potential snowfall totals and what areas
would be more favored. However, it does look like much of this
coming week into the weekend will remain on the cooler side of
normal more often than not and unsettled with periods of valley
rain and mountain snow and more cloud cover than sun.

.AVIATION /00Z TAFS THROUGH 00Z WEDNESDAY/...
Issued at 939 PM MST Mon Nov 17 2025

VFR conditions are in place with the lower cloud deck at KASE
scouring out late this evening. ILS cigs remain in place at a
few sites but these too are forecast to scatter out through the
night. Residual moisture and additional moisture wrapping into
the 4 Corners region through the day tomorrow will spread
isolated to scattered showers northward with a few sites having
PROB30 groups for passing showers. At the moment VFR will
prevail with the probability of lower flight criteria too low to
put in TAF.
