A low pressure system will move through the Ohio Valley Tuesday night and Wednesday. As it does, rain and snow will transition to all snow Tuesday evening with snow then continuing into the day on Wednesday. While several inches of snow may fall, pavement temperatures are quite warm this time of year. Travel conditions may become difficult during the heaviest snow, but highest accumulations will be on natural surfaces and pavement will likely be wet to slushy. Any increase in accumulation forecasts may increase accumulation potential on pavement, but only for the short term.
Natural surface accumulation: 2-4 inches with higher amounts possible
Pavement accumulation: 0-2 wet, slushy inches WITH HIGHER AMOUNTS POSSIBLE IN SPOTS
