This weeks weather....

so how horrible will the roads be with 1/4" to 1/2" of ice?

Any ice is bad ice. Salt will help and it is supposed to be warm, but who knows!

Pretty horrible if the surface temperature stays below 30F.

As for Saturday's attendance... the way things are looking now, it seems that it will just be rain, so it shouldn't hurt anything. Temperatures are forecast to hover around freezing Friday and rise above freezing Saturday, so the main roads and most other roads should be alright.
