Duane: I lived in Idaho Falls for a winter and there is a chance of snow that early, but not much. And the risk is in the higher elevations, not so much on the prairie or anywhere below 4,000 feet. If it were to snow in mid-September, however, I'd think we'd be delayed for only a few hours until plows and/or sun cleared it away.
If you're headed north from LaPine, as in Banff, all bets are off.
That's frickin Canada, bud. They have snow in June.
