National Weather Service Denver/Boulder CO
328 PM MDT Fri Sep 20 2024
.DISCUSSION...Tonight and Saturday...Dry and warm weather with
elevated fire weather conditions will be replaced with cooler
weather and higher humidity readings. A cold front will move
across the plains and back into the foothills very late tonight
and early Saturday morning. Temperatures will fall back to below
normal readings, while high mountain valleys have one more warm
day. Scattered showers and isolated thunderstorms will develop and
spread northeast into the area during the late afternoon as the
next storm system approaches.
LONG TERM DISCUSSION...Saturday night through Wednesday...
A storm system should will provide a wetting rain and/or snow
across the forecast area through the first half of Sunday. Well below
normal temperatures are forecast for Sunday. A weak storm system
or two may pass through the region Monday and Tuesday with light
precipitation, with a warming and drying trend after that. Smoke
dispersal should be fair to very good on Saturday, with poor to
good conditions likely Sunday through 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...
