Deslexia

Hey gents, I'm a longtime lurker here and finally registered. I'm a weather novice that goes full weenie mode during the winter. Been following the Central Ohio folks for a few years now (welcome back Buckeye!) and I really appreciate the input you all provide. Any input as to "why" the storm is going to end up more NW? In addition, can someone explain the WTOD and what it is/why it usually screws Central Ohio out of significant snow?
