Except along the Canada-ID-MT border, all of the precipitation is in the form of rain. There is a line of strong thunderstorms from Cleveland through Cincinnati to Nashville to Huntsville. A few thunderstorms will also be affecting the NYC-area airports, if this is a perfect forecast. In the West, heavy rain is forecast for both Seattle and Portland.
Things get a bit better at 6pm Wednesday:
Snow is falling from northern Maine through western NY and down through the mountains of WV. There is enough rain from NYC through Boston that there will be flight delays.
