Before a more potent storm brings March to an end on an extremely snowy note across the Northeast, a zone of wet snow will fall from the Ohio Valley to the mid-Atlantic today into tonight.
Today's snow will continue to expand from the Ohio Valley to the central Appalachians, even falling as far east as Virginia's Shenandoah Valley.
"This will be the third such system to do so in less than five days," stated AccuWeather.com Expert Senior Meteorologist Alex Sosnowski on Tuesday.
While the late-week snowstorm could bring severe disruptions to travel and daily routines, the snow through tonight will prove to be more of a nuisance event for residents.
Snow totals into tonight will be held under 3 inches, away from the West Virginia mountains. Most of the accumulating snow will be confined to grassy and elevated surfaces during the daylight hours.
More roads will turn snow covered and slick tonight with cooling temperatures and the loss of the stronger late-March sun's energy.
A bit of wet snow and rain will linger across the mid-Atlantic on Thursday as the storm set to become a more substantial snowmaker approaches.
