Lake Effect is governed by Wind Direction and Temperature difference between the Lake surface and the air. With the Lake Surface being so warm, it doesn't take much more than a breeze to get things going. Watch how the Lake Effect band shifts as the winds turn from the SW to the NW. Buffalo NY gets it on a SW wind while Ashtabula Ohio gets it on a NW wind. If this was snow, there'd be FEET with Thundersnow! #NYwx #PAwx #OHwx | Mark Margavage's Weather Discussion Page
