Boise Region Daily Snow
By Matthew Platt, Forecaster Posted 2 months ago December 10, 2023
Thank goodness we have a storm this weekend and into early next week because the pattern is going to be very dry for at least 10 days or so starting Tuesday. Let's take a look!
Short Term Forecast
Strangely enough, there isn't much agreement between the different models regarding the storm that will impact us on Sunday. The GFS is bringing in about an inch of liquid while the Euro keeps everyone at half an inch. The National Blend of Models shows the expected precipitation totals below through Monday:
It looks like Tamarack, Brundage, and Bogus are forecasted to get about half an inch of liquid.
The storm is forecasted to stay just north of Tamarack and Brundage through the rest of Saturday and the overnight hours. They could pick up some stray scraps of moisture, but I don't expect a whole lot in the way of precipitation. The storm will move south around mid-day Sunday and last through early Monday morning.
There is a bit of uncertainty with all locations for snowfall. The NAM3k has the storm far enough south through Saturday night that Tamarack and Brundage pick up good precipitation during the overnight hours. I will stick with my initial forecast of 4-8 inches for Tamarack and Brundage through Monday but I am hoping for some upside surprises.
Conversely, some of the models have the storm fizzling out north of Bogus and there not being much more than scraps left over. I am hopeful though and think they pick up 3-6 inches. I don't expect much if any snowfall south of the Snake River Valley.
Nada, zip, zero, zilch. There is nothing for the next 10 days at least. The bright side is that temperatures will be at average to slightly below average. I don't expect much loss of snowpack other than sublimation (snow to water vapor).
Do them snow dances and pray we get lucky! My next post will be on December 11th.
Sawtooth Avalanche Center (SAC) added the Boise Mountains to their web-based observations platform at Sawtooth Avalanche Center » Observations. This is great news for those of you traveling into and riding the backcountry! Be sure to make liberal use of those observations as you venture out.
