National Weather Service Denver/Boulder CO
309 AM MDT Sun Sep 22 2024
.DISCUSSION...Today and tonight...
No fire weather concerns in the short term period. Rain showers will
end this afternoon. Temperatures remain cool and humidities above 40
percent across northeastern Colorado. Below normal temperatures are
expected through tonight.
LONG TERM DISCUSSION...Monday through Thursday...Warmer and drier
conditions are expected through the week as a ridge builds over
the region. A weak system may bring an isolated shower or two late
Monday into Tuesday, but no wetting precipitation is expected.
Humidity values should generally remain above critical thresholds,
with light winds through most of the period. Most locations will
see fair to very good smoke dispersal each day.
...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...
