You can either provide a complete 6-character PIL/AFOS ID or provide
the 3-character base ID (e.g., AFD). The start and end
dates represent 00 UTC for those dates. The Zip format is useful as
the filenames will have the product timestamp, which is useful for

Fire Weather Forecast for Northeast and North Central Colorado
National Weather Service Denver/Boulder CO
400 AM MDT Wed Oct 21 2020
...RED FLAG WARNING IN EFFECT FROM NOON TODAY TO 8 AM MDT
THURSDAY FOR GUSTY WINDS AND LOW RELATIVE HUMIDITY FOR THE
FOOTHILLS, FIRE WEATHER ZONES 215 AND 216...
...RED FLAG WARNING IN EFFECT FROM NOON TODAY TO 7 PM MDT THIS
EVENING FOR GUSTY WINDS AND LOW RELATIVE HUMIDITY FOR THE
NORTH, MIDDLE, AND SOUTH PARKS, FIRE WEATHER ZONES 211, 213,
214...
.DISCUSSION...Today and tonight...Winds will increase in the
mountains today, with humidities dropping into the teens. The
strongest winds will remain over the higher east slopes of the
Front Range this morning with gusts to 50 mph possible, then less
intense winds will spread into the lower foothills and valleys
this afternoon with gusts to 40 mph. This afternoon will also be
dry and breezy on the plains. Humidities will be higher across
most of the plains, but areas south and southeast of Denver may
approach Red Flag conditions for a few hours this afternoon.
Conditions will improve in the valleys this evening, but the wind
will continue over the rest of the mountains with poor recovery
overnight. Stronger winds may push down into the lower foothills
with gusts up to 50 mph late tonight.
LONG TERM DISCUSSION...Thursday through Sunday...It will remain
windy across the mountains and mountain valleys Thursday.
Meanwhile, a cold front slides south along east slopes of the
mountains and across eastern Colorado. This will bring colder air
and higher humidities to the foothills and eastern Colorado. Windy
conditions will linger across the mountains and mountain valleys
through Saturday, though relative humidities will trend higher each
day. For the foothills and eastern plains, cool temperatures and
higher humidities will prevail through the weekend and into next
week.
...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...
