.DISCUSSION...Today and tonight...
Temperatures east of the Front Range will warm from those observed
yesterday, with a drop in (but still modest) humidity readings.
Scattered showers and storms will occur in the mountains, with a
few of these spreading or developing into the lower elevations
mainly along the I-25 Corridor very late this afternoon or
tonight. Wetting rains can be expected from most of these.
LONG TERM DISCUSSION...Thursday through Sunday...
Unsettled weather with scattered to numerous showers and storms
producing wetting rains can be expected each day Thursday through
Saturday. Temperatures will be a little cooler again with
relatively high humidity readings. Sunday will be a transition day
with a trend toward drier weather into early next week. No
significant winds or fire weather threats are expected through
this entire 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
