.DISCUSSION /Through Tuesday/...
Issued at 245 PM MST Tue Nov 4 2025

Another day of record or near-record highs occurred today with
many areas across the plains hitting the upper 70s and
temperatures hitting the mid 60s in the mountain valleys. A weak
cold front is currently in northeast Wyoming and across South
Dakota that will move across our forecast area late tonight. This
will turn winds to the northeast in the morning hours across the
plains and will keep temperatures 5-10 F cooler on Wednesday. A
DCVZ will setup on the east side of Denver metro with highs around
70 on the east side and highs in the mid 60s on the west side.

There are two main things to discuss in the long term besides the
generally mild and dry conditions. Those are multiple days of
elevated fire weather conditions and two very light snow events
for the northern mountains.

As for fire weather, Thursday will be mild, dry, and breezy
over the northern-most counties across the plains. This will lead
to elevated to near critical fire weather conditions from Greeley
to Holyoke and north to the WY and NE borders. On Saturday, wind
gusts up to 35 mph will spread across all of the eastern plains.
Temperatures will be closer to normal so relative humidity will
drop to around 20% which will result in elevated fire weather
conditions. The other days during the long term period will see winds
and humidity that will be lower than Red Flag criteria.

As for winter weather, a trough on Thursday and another early
Saturday morning will bring just enough moisture and orographic
forcing to the northern mountains of Colorado to produce snow. The
Park Range will see the highest snowfall amounts but only a
couple of inches will fall.

Ensemble guidance doesn`t show a decent signal for precipitation
across our forecast area until November 14-16th. Even then, it is
highly uncertain the plains will receive precipitation during
this period. Otherwise, temperatures will be 10-15 F above normal
with a chance for record highs especially Monday and Tuesday of
next week.

.AVIATION /18Z TAFS through 18Z Wednesday/...
Issued at 1135 AM MST Tue Nov 4 2025

VFR conditions through the TAF period. Winds are expected to be
light and variable for much of the daytime today at DEN and APA.
There may be brief periods of gusty westerly winds up to 20 knots
but these won`t last long. Winds are expected to be westerly and
light tonight instead of drainage. A cold front is expected to
move through between 08-11Z with brief northeast winds behind it.

The wind forecast for DEN and APA will be difficult tomorrow. A
DCVZ will setup very close to each airport. At this time,
southeast winds are expected with gusts up to 28 knots possible.
However, light north-northwest winds could occur for large
portions of the day.
