Fire Weather Forecast for Northeast and North Central Colorado
National Weather Service Denver/Boulder CO
127 AM MDT Sat Sep 5 2026
.DISCUSSION...Today and tonight...A slight increase in moisture is
expected today, leading to a few more weak showers and
thunderstorms across the region this afternoon into tonight.
Chances for wetting rain will be low (<30%) except for portions of
far northeastern Colorado. Daytime humidity values should remain
between about 17-30% with weak winds this afternoon.
LONG TERM DISCUSSION...Sunday through Wednesday...A slow increase
in moisture is likely to continue this weekend into next week.
Chances for afternoon showers and thunderstorms will continue each
day, though the chance of wetting precipitation on any given day
will still be fairly low. Neither humidity or winds are expected
to approach critical thresholds during the 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...
