What's lake effect snow and how does it form?

Here's a quick explanation

At first glance, this doesn't appear to be a powerful storm -- perhaps a 1-3 inches type of storm -- but keep in mind that the upper level disturbance that will create this storm is still out over the Pacific, and won’t cross onto the continent for another day or so.  Only then will we be able to study its physics with data from our land-based upper air weather balloon network, at which point the computer models should start coming into better agreement on its strength and track.
