Does it snow in Missoula? Ahhh...yes, it does.
To your real question; we have not any kind of record snow this year. It has been pretty dry in the valley actually but nothing as bad as I've heard about the Bozeman area. The Gallatin basin snowpack looks really bad...like 60% of average.
As Dave mentioned, we had one really good storm last month that brought the snowpack up to and above average in most of the basins around here. It was an impressive, and important, snowfall.
You can google "snowpack" and find graphs and charts that show "percent of average" for specific drainages, i.e. Upper Clark Fork, Bitterroot, etc. but they are hard to read and follow. "Percent of average" is based on the average for this day in history. So while they are a good gauge to follow, they cannot predict what the summer flows are going to be like.
There are too many different factors to take into account. There could be a big, late snow fall that pushes average up. There could be a very long, cool spring that delays runoff. There could be a combination of both. It could be the opposite. I've seen good snowpacks come down way too fast during an overly hot spring and runoff is over by June 15 and rivers are low by August.
Basically, I am being no help to you. I don't like to predict what the water year will be. It's foolish. By June, then it is safe to make predictions because our summers are very stable and we never rely on rain after June.
But as of now, the snowpacks in W Montana are close to average. Man...that took a long time to answer your question. Sorry!
