Fire Weather Forecast for Northeast and North Central Colorado
National Weather Service Denver/Boulder CO
258 PM MDT Fri Sep 25 2026
.DISCUSSION...Tonight and Saturday...A round of scattered showers
and thunderstorms will move east across the plains through this
evening. Wetting rains can be expected from most storms. Humidity
will be high through tonight, although gusty west winds to around
30 mph will develop over the mountains and higher Front Range
Foothills and start to bring in drier air. Saturday will feature
warmer and dry conditions. Humidity readings will lower to 15-22%
over most of the plains, with northwest breezes.
LONG TERM DISCUSSION...Saturday night through Wednesday...
Warm and dry weather will persist through Sunday, although an
isolated shower or storm will be possible in/near the higher
terrain. Fire weather conditions will become elevated on the
plains due to breezy south winds gusting to 25-30 mph and minimum
humidity levels 18-25%.
A storm system is expected to arrive early to mid-week next week,
which will bring cooler temperatures along with a chance of
precipitation to much of the forecast area. As of now, the high
country is the most favorable location for rain and potentially
some snow at the highest elevations on Monday night into Tuesday,
but the plains may also see prolonged rain depending on the exact
track and evolution of this next storm. Overall, light winds,
high humidity levels, and potential rainfall will keep fire
weather concerns minimized through this period.
...Thunderstorms imply strong gusty erratic winds...
...All surface winds are 20-Foot...10-Minute averaged winds...
...CWR is Chance of Wetting Rain - 0.10 inch or more liquid...
...24 HR Trends are based on averages over the respective zone
groups and may not match the actual forecast values
shown in those groups...
