Fire Weather Forecast for Northeast and North Central Colorado
National Weather Service Denver/Boulder CO
259 PM MDT Fri Jul 11 2025
.DISCUSSION...Tonight and Saturday... A cold front has kept
relative humidity values well above critical thresholds for the
majority of the forecast area this afternoon. With areas of heavy
rainfall expected tonight and into Saturday morning, and relative
humidity values expected to remain well above thresholds again
tomorrow, no critical fire weather conditions are expected in the
short term.
LONG TERM DISCUSSION...Saturday night through Wednesday...An upper
level ridge will begin to build over the southwest on Saturday
that will bring a return of hot and dry conditions for the first
half of the week across the forecast area, but winds are not
expected to reach critical thresholds. With relative humidity
values progressively decreasing through the weekend, there may be
some localized elevated fire weather conditions that develop, but
overall, no critical fire weather conditions are expected through
the long term 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...
