By mid April you can usually feel comfortable in not having prolonged snow events. in other words, plan an extra day or so for your travels across Wyoming in case you need to hunker down somewhere and wait a storm out. Sometimes it can happen that there's a big storm on I-80 but nothing on I-70 or vice versa, so keeping your options open can help. Also by mid April, the sun is up long enough and high enough in the sky to melt roads off pretty quickly (most of the time). I mean some years we can get a doozy of a storm in early to mid May, but most years not. I remember skiing 29" of new snow May 4th (or so) at Loveland Basin by the Eisenhower Tunnel on I-70.

As far as the Utah parks, Bryce (8000') and Cedar Breaks (10,500') are the only ones high enough to have snow concerns in April and May. We've hit 100+ temps in Moab on Memorial Day weekend. Zion is further south so warmer yet.
