512 AM MST Fri Dec 12 2025



Forecast is based on ignition time of 0600 MST on December 12. 

If conditions become unrepresentative...contact the National Weather

Service.



.DISCUSSION...A ridge of high pressure will remain the dominant forecast

influence over the next several days. This will result in dry and

stable conditions, limited mixing, and in turn poor daily 

clearing index values. Winds will tend to favor a west- 

northwesterly to terrain driven direction. Models support some 

potential for a system to move through around the middle of next 

week, though uncertainty is noted in the southern extent to 

associated moisture. While that aforementioned uncertainty will 

result in likely changes day to day, current forecast carries 

around 0.05" to 0.10" of water (0.2" to 0.5" snow) on Wednesday 

with this system.
