Fire Weather Forecast for Northeast and North Central Colorado
National Weather Service Denver/Boulder CO
316 PM MDT Sat Sep 18 2021
.DISCUSSION...Tonight and Sunday... There may be a few showers and
storms tonight mainly over the higher terrain. Tomorrow will be
warm and dry again. Winds will be rather strong tomorrow with
gusts up to 35 mph in the higher terrain and 30 mph across the
plains. A passing upper level disturbance will bring enough low
level moisture tonight to keep relative humidity above 15 percent
in all locations. The winds will create elevated fire danger but
critical fire danger is not expected. Smoke dispersal will be
excellent to very good.
LONG TERM DISCUSSION...Sunday night through Thursday...A weak upper
trough will moves across the forecast area Sunday night and Monday.
Decent precipitation amounts are not expected. After that, upper ridging
dominates through Thursday with a dry and warm air mass in place.
There could be some elevated fire danger during the afternoon hours
of Wednesday and Thursday over a few areas in the north central mountains.
...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...
