Snowfall Wednesday will vary tremendously across the state, with very heavy amounts expected over the far northwest corner of Virginia, while central and eastern Virginia should see comparatively much less.
Still, several inches of a slushy, wet snow will be possible around metro Richmond, falling mainly from afternoon through early evening after it changes over from rain. With much of the falling snow melting, especially in lighter snow bands, accumulations could be difficult to build at first. Heavier bands, where they develop (most likely northern half of state) will have greatest ability to accumulate.
Winter Storm Watches are in effect west and north of Richmond, and we'll see if those are expanded to include more areas as the details of this system become more apparent. Right now we think the metro area could see as much as 4" over the western suburbs, with lower amounts elsewhere.
