For many valley locations, this is the first significant snowfall of the season


We've already seen snowflakes across the valley during this cool season, but it hasn't amounted much. The most snowfall reported at the airport to date is 0.10". Friday is expected to bring the first significant snowfall to the area, and by significant, I mean an inch or more. By comparison, Boise usually has its first inch or more of snowfall on or around December 5. Last year, our first inch of snow fell on December 8, this puts us just 10 days behind if everything pans out.

The forecast calls for a storm system to move in from the north Pacific through the region Friday evening. This will bring changes to our stagnant weather pattern for the weekend. The cold front will help sweep out the inversion and bring light snow across the region into early Saturday morning. This isn't a significant snowstorm that will deliver feet of snow to our mountain regions, although we could use it to build our current snowpack. But, it will be the most significant storm so far this season for many valley locations.

Most valleys are expected to see roughly an inch of snowfall, maybe less in the lower valley along the Idaho and Oregon border, and up to 3 inches in the mountains. The storm will move through quickly overnight and clear out the inversion for the weekend.

With the passing front, winds are expected to be strong on Saturday with the strongest winds from Mountain Home to the Magic Valley. With the inversion out of the way this weekend, temperatures will be near average with highs in the mid-30s.
