.DISCUSSION...Tonight and Sunday...
A few showers may linger into the overnight hours over the
mountains. Otherwise, quiet weather is expected tonight with breezy
conditions at the peaks. Sunday will be much warmer, and likely the
driest day of the week, although minimum humidities will stay in the
30%-50% range at the high elevations. For the plains, minimum
humidities will be lower but still above critical thresholds, near
20%-25%. Gusty SSE winds will develop late Sunday afternoon over the
eastern CO plains, and there will also be a chance for virga showers
to produce strong erratic outflow winds, up to 50 mph.
LONG TERM DISCUSSION...Sunday night through Thursday...
Shower coverage will increase over the mountains Sunday night into
early Monday morning, with breezy conditions (15-25 mph) at
elevations above 10,000ft. We expect showers and thunderstorms to be
possible each afternoon and evening through Thursday. Locally heavy
rainfall may occur on Tuesday and Wednesday as monsoonal moisture
intensifies. Temperatures will trend cooler much of the week starting
with the passage of a cold front on Tuesday.
...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...
