Spot Forecast for Headquarters/Eagle Cliff RX...USFWS
National Weather Service Denver/Boulder CO
1154 AM MST Wed Nov 4 2026

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

.DISCUSSION... The forecast was updated to take out the mention of
snow showers. It appears only flurries with no accumulation would
be the worst case scenario today. Otherwise, today will have light
winds generally out of the east between 5-8 mph. Smoke dispersal
will be marginal throughout the afternoon.

Very similar conditions are expected on Thursday. Winds will be
light and will mostly be out of the east. With slightly warmer
conditions, mixing heights will reach 5 kft allowing smoke
dispersal to be marginal to fair. No measurable precipitation is
expected for the next 7 days.
