Frequent deviations around convective cells while negotiating the airways near the minimum en route altitudes (MEAs) is a nightmare from an ATC perspective.
The main issue when operating IFR in the region is that the minimum en route altitudes (MEAs) usually are above 10,000 feet, which often means a constant threat of airframe icing.
In the Western United States, minimum en route altitudes (MEAs) and freezing levels tend to coincide, even in the summer, bringing the possibility of airframe ice.
Many IFR airways out of Idaho Falls feature minimum en route altitudes around 14,000-16,000 feet, and I prefer flying in the 9000-11,000 range.
