If you can get to Round Valley before it thaws, it's a "3" (a few icy spots); As the temps climb, though, the recent rains begin to show their effect. If it's sunny, I usually add at least 3-4 degrees to the air temperature to guess whether the conditions are beginning to soften, so air temps 28-29 degrees and up are suspect. It's possible that the softening may even occur at a lower temp (not tested that yet), but at 29 degrees today (per weather.com), the melt was definitely on. Cloudy days seem to be much more true to the 32 degree freeze point...
