Boise weather: How much snow and rain fell? Is another storm on the way this week?
The wet weather that arrived in Boise over the weekend will be making appearances the rest of this week as well, with a storm system that could bring more snow predicted a few days from now.
For anyone driving around the Treasure Valley, it was impossible to miss the sludgy roads. Boise was hit with 1.06 inches of rain and 0.4 inches of snow between Friday and Sunday, according to National Weather Service meteorologist Korri Anderson.
The snow showed up again early Monday morning, dumping 2.2 inches on the City of Trees in pretty short order, according to NWS meteorologist Stephen Parker.
A cold front that’s moving in Tuesday night means Boise could get a very light dusting of snow between 6 a.m. and 9 a.m. Wednesday, Anderson said. But for the most part? Rain, rain and more rain. Highs in the 40s will keep it from snowing.
Precipitation is expected to fall on and off Monday through Friday. Anderson said Boiseans should expect up to a half-inch Tuesday and Wednesday combined.
By Thursday afternoon, a new storm system is moving into Idaho, leading to a little under an inch of snow Thursday and Friday.
“The system that’s offshore right now is going to finally move inland,” Anderson told the Idaho Statesman by phone. “It’s off of Vancouver Island right now, and it’s just going to sit there through this week (until) Thursday.”
Idaho mountains will be hit hard
As usual, the precipitation expected in the valley is nothing compared to what the National Weather Service says we’ll see in the mountains.
Bogus Basin received 27 inches of snow from Friday to Monday afternoon, while McCall got 15.5 inches and Brundage Mountain 25 inches, Parker said.
By this Friday, according to meteorologists, Bogus should see another 17 inches, McCall 19-24 and Brundage about 33.
All of that is good news for skiers, but the bad news is that it has led to perfect conditions for avalanches, Anderson said.
The Sawtooth Avalanche Center announced a warning had been put into effect Sunday, calling the danger “high and extreme.” The Payette Avalanche Center also warned mountaingoers of treacherous conditions.
“A powerful multiday storm is overloading a very weak snowpack,” the Sawtooth Avalanche Center said in a social media post. “Natural and human-triggered avalanches large enough to bury people are almost certain. Some avalanches will be large enough to snap trees and damage structures.”
The center advised people to avoid traveling in avalanche terrain and to stay away from steep slopes in the Central Idaho mountains.
