336 PM MDT Thu May 15 2025
.DISCUSSION...Tonight and Friday...Winds will decrease tonight,
although it may remain windy in wind prone foothills areas,
especially west of Denver and Boulder. On Friday, it will still be
breezy to windy, with speeds a bit less than they were Thursday
afternoon. Near critical conditions are expected over the plains
and lower foothills in the afternoon hours. Only isolated
afternoon showers and thunderstorms are expected over the
mountains.
LONG TERM DISCUSSION...Friday night through Tuesday...
There will be a more moisture on Saturday, with higher humidities
and scattered thunderstorms, especially north of Interstate 70. On
Sunday, it will be drier and windier again from I-70 south, with
more uncertainty about whether it will be wetter or drier in the
north. Near critical conditions are likely in the south, and
possible in the northern plains. Monday and Tuesday will be breezy
and cooler with higher humidities and a higher chance of
precipitation.
...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...
