National Weather Service Denver/Boulder CO
151 PM MDT Sat Sep 19 2026
.DISCUSSION...Rest of today through Thursday...Numerous
thunderstorms are expected this afternoon and evening over the
plains, with locally heavy rain and relatively widespread wetting
rains. Coverage will be isolated/scattered over the urban corridor
and mountains. Isolated to scattered showers and storms will
continue into Sunday, favoring northern parts of the area during
the morning and southern portions of the forecast area later in
the day. Temperatures will trend cooler Sunday into Monday, before
warming again starting Tuesday, although isolated to scattered
daily showers and thunderstorms will likely continue, favoring the
mountains. Light winds (outside of thunderstorm outflows) and
elevated humidity levels will keep fire weather concerns limited
through the period.
...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...
