Fire Weather Forecast for Northeast and North Central Colorado
National Weather Service Denver/Boulder CO
317 PM MDT Fri Apr 19 2024
.DISCUSSION...Tonight and Saturday...Snow become widespread east
of the Continental Divide this evening and continues overnight
before ending Saturday morning. Even though the snow ends Saturday
morning, cool and moist conditions will persist through Saturday.
West of the Continental Divide will be drier with relative
humidities falling into the 30s in the valleys. It will also be
breezy with westerly gusts to 25 mph.
LONG TERM DISCUSSION...Saturday night through Wednesday...Warmer
and drier conditions are expected by Sunday, though humidity
values will likely remain above 20 percent across the region.
Light upslope flow across the plains will lead to generally poor
dispersal for the lower elevations, with good to very good smoke
dispersal for the higher Foothills, South Park, and areas west of
the divide. The warming/drying trend is expected to continue
Monday with increasing winds. Good to excellent smoke dispersal is
forecast, though some areas may see elevated fire weather
conditions if a drying trend continues. Guidance shows a series of
weak storm systems tracking across the region through the week,
with generally mild and dry conditions. Widespread wetting rain
looks unlikely with any of these systems, but isolated to
scattered showers/thunderstorms will be possible each afternoon.
...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...
