National Weather Service Denver/Boulder CO
550 AM MST Mon Dec 8 2025

If conditions become unrepresentative...contact the National Weather
Service.

.DISCUSSION... Today will be breezy with light snow in the morning
and partly cloudy skies in the afternoon. Additional snow
accumulation should be minimal (less than 2"). The wind gusts
could reach 35 mph especially during the morning hours. The
relatively high vent rates and wind will allow for good smoke
dispersal throughout the daylight hours.

Tuesday will likely be dry with only a few flurries possible. Vent
rates will be a bit lower than Monday and winds will remain about
the same with gusts up to 30 mph. This will result in fair to good smoke
dispersal throughout the day.
