Yea, the mountains are all covered with snow, but the real danger is in the spring if it gets to warm too fast. When we had the floods the snow pack was a little above average, but the killer was that it got real warm real fast and then rained.
I would bolt two pieces of angle iron or even 2X4 about 6" below the peak of the trusses, then center a bolt through the middle of the angle iron and hang the 3/8" running thread from that bolt. Then I would drill 7/16" holes in the I beam as close to the center as I could (alternating sides) to the vertical and still use a nut and washer. The running thread will give you the ability to adjust the I beam if you need to and it doesn't cost much either. We buy lots of running thread, strut, nuts & bolts etc. from FASTENAL, they've been the best least expensive source I've found for that sort of thing.
