So I am in a temperature holding pattern at the moment. It's been stuck on 35.1 for awhile now. I had 3.5" of snow before it mixed and switched to sleet. I'd say about another inch of the mix fell after that (rain compaction likely, though) for a total that I'm calling at my house of 4.5 inches. It's not official by any means, but it's in the ballpark.
So far, I'm still at home. Only one driver went in so far, and he said that if no others show up, he's going home. He said roads in my area had heavy slush on them and were rutted. One would think that the plows and the salt with a fairly high temperature would do them well, unless there's not a lot of plows out due to the holiday and schools being off.
Anyway, I'm taking a "wait a bit" approach as to whether I go in.
