.DISCUSSION /Through Thursday/...
Issued at 1127 PM MST Thu Feb 12 2026

Area radars are indicating scattered light rain showers, mainly over
the northern half of the CWA`s plains.  The showers are dissipating
as they move east. The northern border counties actually have dew
point readings in the mid 30s F right now.  Some places may actually
be getting a few hundredths of measurable rain! There are also
some light snow showers in the mountains at present. The CAMs keep
the scattered showers going over the CWA until about 07Z-09Z
tonight.

Southwesterly flow aloft will decrease overnight and on Friday as an
upper trough moves eastward towards Colorado.  This trough moves
across the CWA Friday night into Saturday morning bringing a quick shot
of precipitation to the CWA. A brief period of deep moisture
accompanies the trough Friday afternoon and evening for most of
the CWA, especially over the mountains. There is limited synoptic
scale energy with the trough on the QG Omega fields, with the
best energy still progged south of Colorado. There is little to no
cold air advection for the CWA. Cross sections indicate virtually
no alpine orographic snowfall enhancement as mountain top winds
are very light and due northerly in direction. So, there will be a
brief period of light to moderate snow anywhere from 2 to 6
inches. The highest amounts look to be in zone 34. Expected
snowfall amounts do not warrant any highlights.

Over the plains, the trough will bring likely pops for all but the
northeast corner, mainly just Friday evening, decreasing after
midnight.  It looks warm enough for it to all all rain.

There is upper ridging west of the CWA early on Saturday with
moderate northwesterly flow aloft. The ridge axis is over Colorado
by Saturday night into Sunday. Moisture is sparse Saturday into
Saturday night, then some upper level moisture moves in through
Sunday night.  It will be dry.

With the warming expected on Sunday, fire weather conditions will
become elevated, especially over Park County by afternoon.

Temperatures continue to stay above seasonal normals Friday and
Saturday with highs in the lower 50s to 60 degrees over the plains.
On Sunday, readings warm further with highs in the lower to mid
60s.

For the later days, models have southwesterly flow aloft dominating
Monday through Wednesday. This flow becomes quite strong from Monday
night through Wednesday with jet level speeds as high at 170 knots.
The flow aloft weakens considerably on Thursday as upper troughing
approaches from the west. There is plenty of moisture around
Monday, but mostly aloft. Cross sections show low level moisture
increasing in the mountains and significant mountain top winds
Tuesday and Wednesday with snow a good bet both days. Even though
wind decrease on Thursday, there still looks to be a chance of
alpine snow. Over the plains, models continue to show elevated to
critical fire weather conditions during the afternoon hours all
four days, Monday through Thursday. Humidity levels drop below 20
percent during the afternoon hours each day and strong west and
southwesterly winds are progged. Tuesday, especially is of
concern, where models are showing wind gusts up to 50 mph by
afternoon over the plains. Temperatures will continue to be well
above seasonal normals Monday and Tuesday, cooling a bit Wednesday
and Thursday. The plains are dry all four days.

conditions are expected through this afternoon (00Z Saturday). The
light south winds turn to the north after 18Z. Clouds increase after
21Z as the next storm system moves into the area. Ceilings lower and
showers form, mainly after 00Z Saturday. Ceilings are expected to
fall to 1000 to 3000 feet, mainly 03-12Z Saturday. Drier air moves
