Fire Weather Forecast for Northeast and North Central Colorado
National Weather Service Denver/Boulder CO
151 PM MDT Sat Jul 19 2025
.DISCUSSION...Tonight and Sunday...Scattered storms and showers
are expected through the evening tonight. Ordinary storms across
the higher elevations may intensify as they move east across the
plains, with some severe storms possible near the northeastern
portion of the forecast area (WY/NE border areas). These storms
may become very electrified where lightning strikes would be more
pronounced. Localized heavy rainfall within some of the stronger
storms should help put any lightning strike fires out, but there
could be strikes that are too far away from the precipitation to
be snuffed by the rain.
Drier conditions are expected on Sunday, with isolated showers
and storms possible in the afternoon for the higher elevations and
eastern plains. Smoke dispersal will be fair to excellent across
the forecast area.
LONG TERM DISCUSSION...Sunday night through Thursday... Warm and
dry conditions will continue into Monday. In general, winds will
be light as Colorado remains under a broad upper-level ridge. By
mid-week, monsoonal moisture looks to increase across the
forecast area, and there will be a widespread chance for wetting
rains, with Wednesday looking to be the wettest day. No critical
fire weather conditions are expected 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...
