If you live in Virginia, you may want to stock up on the essentials this week in preparation for up to a foot of snow throughout the state.

There is a high ceiling for how much snow the storm could generate, but it could also just produce a glancing blow or even head out to sea with little impact.

Winter storm warnings extended from Kentucky to southern New Jersey, and a flood watch was posted for a wide swath of Kentucky, Tennessee, southwest Virginia and northern Georgia. The snow-and-ice mix was expected to become all rain as temperatures climb by Wednesday afternoon.
