National Weather Service Denver/Boulder CO
309 PM MDT Sun Jun 15 2025
.DISCUSSION...Tonight and Monday...Warm and dry conditions will
continue through Monday. Scattered showers and thunderstorms will
be possible again across the northeast corner of the forecast area
Monday afternoon, with little precipitation elsewhere. Daytime RH
should fall to around 10 percent across most of the higher
elevations and I-25 corridor, with better moisture off to the
northeast. Smoke dispersal should be good to excellent.
LONG TERM DISCUSSION...Monday night through Friday...A storm
system will bring better chances of rain to the region on Tuesday,
along with a modest cooling trend. A warming and drying trend will
quickly return for the latter half of the week. Elevated to
critical fire weather conditions will be possible by Thursday or
Friday as a very hot/dry airmass develops and winds begin to
increase.
...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...
