.DISCUSSION /Through Wednesday/...
Issued at 130 PM MDT Wed Sep 24 2025

Our weather will be dominated by an upper level ridge which will 
build and hold across the state through Saturday. This will 
support sunny skies, dry conditions, warm daytime temperatures, 
and light winds. High temperatures each day will be several 
degrees above normal. A weak backdoor cold front Friday night is
expected to bring slight cooling (just 2-5 degrees) to the plains
for Saturday. 

The next chance of any precipitation won't arrive until late
Sunday as eventually the ridge moves off to the east and a
shearing trough lifts out of the Desert Southwest. For the most
part, moisture associated with this trough stays to our west, and
therefore the main chance of showers and storms will be confined
to the mountains and western Colorado.  

While there is more uncertainty in the trough position and any
potential shortwaves Tuesday into Wednesday, there is reasonable
agreement we'll stay in some sort of southwest flow. Thus, the 
main chance of any showers or storms will stay over the mountains
and western Colorado. This pattern would also be favorable for a 
continuation of above normal temperatures through the middle of 
next week.

.AVIATION /18Z TAFS through 18Z Friday/...
Issued at 1128 AM MDT Thu Sep 25 2025

VFR conditions and normal diurnal wind patterns will persist
through this period. Once light east/northeast winds establish
themselves by 20Z, expect a gradually clockwise turn through 16Z 
Friday, only to become light and VRB again before returning to 
east/northeast after 20Z Friday.
