Fire Weather Forecast for Northeast and North Central Colorado
National Weather Service Denver/Boulder CO
223 PM MDT Sun May 19 2024
.DISCUSSION...Tonight and Monday...It will turn a little cooler
with higher humidity in most areas for Monday. Scattered showers
and isolated thunderstorms will end this evening, but another
round is expected again on Monday. Those will have a better chance
of producing wetting rains, especially along and east of the Front
Range. Westerly winds this evening will shift northerly behind a
front that pushes across the plains overnight. Then east/southeast
winds will increase tomorrow afternoon across the plains and
Palmer Divide.
LONG TERM DISCUSSION...Monday night through Friday...
Scattered to numerous showers and storms are possible starting
Monday afternoon through late Tuesday. This will lead to low fire
weather concerns. Depending on fuels, elevated fire weather
conditions could return as early as Thursday afternoon mainly for
South Park, the Palmer Divide, and adjacent plains. Relative
humidities drop between 15-18 percent and southwesterly winds could
produce wind gusts up to 20-25 mph. Smoke dispersal conditions
increase near good to excellent for parts of the high country
Tuesday and Wednesday.
...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...
