Junipers and Arborvitaes (Thuja) seem to be the worst; spruces generally less injury.
Arborvitaes are at a disadvantage here in the Denver area - they are native to areas with more humidity in winter. Arborvitaes planted in local landscapes commonly show some "winterburn" after a dry windy warm winter with low humidity and little snowcover.
To add insult to injury, the cold snap of April 9 damaged needles badly (see photos)....many arborvitaes and junipers (especially sheared junipers) show injury. About all you can do now is water them, wait to see if any new growth appears late May-June and prune out twigs that still appear dead/brown. Some arborvitaes may be total losses.
