Fire Weather Forecast for Northeast and North Central Colorado
National Weather Service Denver/Boulder CO
321 AM MDT Tue May 14 2024
.DISCUSSION...Today and tonight...
No fire weather concerns today. Scattered afternoon thunderstorms
are expected, and will be most numerous along and south of I-70
where a few could be strong and produce brief heavy rain/hail and
locally strong but short-lived outflow gusts of 45-60 mph. Otherwise,
expect minimum relative humidity values of 16 to 22% in for the
lower elevations, and prevailing northwest winds around 10 to 15 mph.
Smoke dispersal will be Excellent for the entirety of the forecast
area for several hours this afternoon.
LONG TERM DISCUSSION...Wednesday through Saturday...
Wednesday will be cool with scattered to widespread showers and
thunderstorms. This will keep fire weather conditions on the lower
side. A warming and drying trend will begin Thursday and last
through the weekend. On Friday and Saturday, relative humidity
will drop to the mid teens across the plains. Neither day will be
particularly windy but gusts will be around 20-25 mph so there
will be areas of elevated fire weather conditions each day. Smoke
dispersal will be good most days across all areas.
...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
