Starting to get worried about sleet around here in Asheville. 3km NAM is even colder a 850mb. Surface temps look to stay in the low 30’s per NAM, but RGEM is colder. Will all depend on how deep the frozen layer is above your house. If you are getting sleet, it’s cold enough and deep enough to re-freeze the precipitation. If you by chance have snow, then your 700mb temps are not warm enough to initially melt the precipitation. If your surface temps are below freezing but it’s raining, the frozen layer is not deep enough to re-freeze the precip. I am very interested to see how this unfolds.
