.DISCUSSION /Through Sunday/...
Issued at 244 PM MDT Sun Aug 31 2025

It's hard to beat this weather for Labor Day weekend. There will
be plenty of sunshine, light winds, and near normal temperatures
today and Labor Day. A ridge aloft over Colorado will keep 
conditions dry although a few sprinkles could occur in the 
southern foothills. 

On Tuesday, high temperatures reach the mid 80s on the plains as
northwest flow increases aloft. Some weak instability will build 
in over the higher terrain and a few isolated showers and storms 
may develop. 

A weak shortwave trough within the northwest flow will move close
to Colorado on Wednesday. Meanwhile, a surface cold front will
move across the northeast plains of Colorado. This will increase
moisture and forcing which will produce scattered storms mainly
over the higher terrain and the Palmer Divide. 

Another very quick-moving trough will move across the Northern
Plains of the US on Thursday. Downslope winds may develop across
the plains which could quickly increase temperatures to the upper
80s across the plains. There will be a chance for late day showers
and storms as another cold front will move across the area in the
evening. 

Friday appears to be the coolest day in the 7-day forecast with
highs in the 70s across the plains. Plenty of areas across the
plains will see lows in the 40s Friday night due to low humidity.
There will be more zonal flow next weekend with the possibility 
that some Pacific moisture arrives. Near or slightly above normal 
temperatures are expected with a chance of afternoon/evening 
storms.
