"Big snow flakes fell early Friday evening, turning Downtown Boise into a 
giant snow globe for people on their way home from work. The snow caught 
many people off guard, including this bicyclist heading down Idaho Street 
between 8th and 9th around 5:45 p.m [image]. Across the Treasure Valley, 
tree branches heavy with wet, snow-covered leaves fell on power lines, 
causing scattered power outages. This is the earliest measurable snowfall in 
Boise since recordkeeping began in 1898, according to the National Weather 
Service."
