1059 AM MST Fri Dec 5 2025

...WINTER WEATHER ADVISORY WILL EXPIRE AT 11 AM MST THIS MORNING...

The period favoring the most impactful snowfall has ended, therefore 
the Winter Weather Advisory will expire. There is still around a 40% 
chance that temperatures stay cold enough in the Cache Valley for 
the bench areas to see an additional 1 to 4 inches of snowfall, 
however, odds are leaning in favor of predominant precipitation type 
to transition to rain through the evening and overnight hours.
