I think you're right to an extent. Since our last snowfall of a whopping 1.3" we have been consistently above normal, and that is definitely a good point. However, before the last event, the highs were in the 70s two days before, and in the 50s the day before, and didn't have much a problem making for messy travel. Granted, there was hail still on the ground when the snow started (I drove in the hail, yay.) It didn't melt immediately on pavement, but at the same time, it was coming down pretty hard for a couple of hours. I think this is the type of thing where it depends on A) How hard it is snowing (likely moderate at best), can the rate it is snowing overcome any possible snowmelt, and B ) How cold it is on Friday, as in will it be cool enough to warm the ground to where mid-20s temps the night before don't do too much of an impact. But yeah, accumulations, if any occur, should not be significant and should for the most part be grass-only. Story of this Winter. First step is to see if we even get measurable snow.
