.DISCUSSION /Through Monday/...
Issued at 1119 PM MST Mon Feb 9 2026

A cold front is pushing through the CWA currently with northeasterly
winds expected overnight tonight. Current satellite pictures are
showing a decent fetch of upper level moisture moving across the CWA
this evening in west-southwesterly flow aloft. Overnight low
temperatures are still expected to remain above seasonal normals
with upper 20s to mid 30s over the plains and mid teens to mid 20s
in the mountains.

There will be zonal flow aloft on Tuesday with plenty of mid and
upper level moisture embedded. The QG Omega fields have weak upward
energy for the CWA.  Cross sections indicate there should be enough
moisture scrapping the mountains for scattered light snow showers
with the QPF fields indicating some light amounts as well. High
temperatures will still be a bit above normal on Tuesday yet
about 15-20 degrees cooler than today`s highs.

Flat upper ridging with strong west-southwesterly flow aloft is
expected Tuesday night all the way through Thursday night. The jet
level flow across much of Colorado is progged in the 100-130
knots range through that period. There is fairly decent moisture
in the mountains on Wednesday, however by later Wednesday night
and Thursday model agreement is poor. The synoptic scale energy
is weak through Thursday night. Just some of the models indicate
enough QPF for advisory snowfall amounts later Wednesday night
into Thursday for the Park Range in Zone 31. No highlights this
update.

Thickness grids continue to show temperatures above normal
Wednesday and Thursday.

For the later days, models are in pretty good agreement showing an
upper trough with a closed circulation at the bottom well south over
northwestern Mexico on Friday. This pushes northeastward Friday
night, with the closed low still well south of the CWA over the
southern half of New Mexico. Upper ridging moves in Saturday and
Sunday, then southwesterly flow aloft on Monday.  There is little to
no upward synoptic scale energy for the CWA all four days. Moisture
is limited with the best chances of light precipitation Friday and
Friday night. After that, there is some spotty moisture around
mainly in the mid and upper levels. There could be minor alpine snow
showers Saturday through Monday. Temperatures look to be 10 to 15
degrees above seasonal normals Saturday through Monday.  Fire
weather conditions will be elevated on Sunday and Monday.

.AVIATION /18Z TAFS through 18Z Wednesday/...
Issued at 1032 AM MST Tue Feb 10 2026

VFR conditions will persist throughout the period. Winds at DEN by
23z should shift to more easterly given the development of a
terrain-induced cyclone to the SW of DEN. Winds should eventually
turn to SE and then to drainage in the evening hours. For
tomorrow, there is some uncertainty as to which direction the
winds will change to following the drainage winds. Went with VRB
for now with an eventual NE around 21z and will allow this to be
updated in a future package. A mid-level deck will develop
throughout the day tomorrow at both DEN and APA.

At APA, the aforementioned cyclone will bring E winds around 21z
and then to drainage by around 04z as the cyclone breaks down. At
BJC, there is a scattered stratus deck currently that will
burn off as the day progresses. Light winds will shift from SE to
NE throughout the day today into the night before becoming
variable tomorrow morning.
