last week of may or the first week of june too early to go to yellowstone

Just returned from the Gran Tetons. Weather changed daily, low of 28 high maybe 35. Tried going to Yellowstone one morning, half way there, snow began to fall. A very wet snow that stuck to everything. About half way there, we had to turn around. Roads cover and to slippery. Park Rangers closed the road, we were have to make it back to the tetons. Next day was better, but they were calling for more snow, after seeing the prismatic springs we left before snow. If you are in Yellowstone and roads are closed. Your not going to leave until roads reopen. Weather deteriorated so much we left a day early. We have been there at the end of June also, chilly for sure and a few flakes. Best planning to go...read all the weather alerts on the website. Be prepared for delays, and road closures. Be patient, drive slowly. no need to rush or you will miss alot.
