National Weather Service Denver/Boulder CO
521 AM MDT Sat Oct 4 2025

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

.DISCUSSION...A cold front will bring scattered showers and 
thunderstorms to the area late this morning into the afternoon 
hours. The best chance of rain is from 12-6 PM today. High 
temperatures today should reach the mid to upper 70s, but will
quickly cool behind the front this afternoon. Minimum relative
humidity will remain near about 30-40 percent. Conditions should
quickly improve this evening with clearing skies.

There is fairly low confidence in the wind forecast today, with
Fort Collins likely remaining blocked from the stronger
southwesterly flow aloft. Winds this morning will initially be
light and variable, and will try to turn to a light easterly
component. The approaching showers/storms and cold front should
shift winds back to the west, with a few gusts of 20-30 mph. Light
Light northerly winds are expected overnight.
