I'm pretty sure there's a place where you can find a map of snow cover across the US, but I couldn't tell you where to find it. Maybe someone else knows?
I had taken a gander at the weather channel's online snowfall map and it suggested 4-8" in those areas, but I suspected there were higher amounts. As you said, this will definitely slow the warming process.
Luckily we only have a few inches here in the KC area to get rid of, which should go pretty quickly Sunday-Monday. And Topeka and Pleasant Hill have added elevated thunder to the zones Friday night. Yippee!!
