The snow that fell late last night didn't come fast and furious. It started at the Salt Lake City airport at around 4:50 AM MST and has added up to a whopping .03" of water equivalent through 8:40 am this morning. That's probably pretty close to what I got in the Avenues foothills.
However, after the cold weather the past couple of days, the road surfaces are cold and the snow is sticking. In addition, I suspect the road crews were caught off guard and nothing was plowed when I woke up this morning in my neighborhood. Further, Commuterlink at 8:48 AM MST showed fairly slow going for a Saturday along much of I-15 and I-215 through the Salt Lake Valley.
