SO we're planning a trip to Moab, UT the end of April coming from the east. I'm hearing that it's not unusual to get snow at that time of year and I-70 may be closed then. Any comments?
We lived in Colorado for 30 years. It can happen anytime, but April will have a pretty high probability. The weather services do provide advanced warning to be able to plan your trip. The worst areas are at the Eisenhower Johnson tunnels and Vail Pass.
Interesting side note, they have been closing eastbound quite often due to sun glare.
