A note about the type of snow that will fall Wednesday. It will be a heavier wet snow than what has fallen previously this winter. Snow to water ratio's of 8:1 to 10:1. That means it will be a good packing snow (snowballs/snowmen) but also means this is more of a "heart attack" snow. Be careful when out shoveling!
