Wider weather episode

Early on the 28th an area of low pressure was tracking through the Ohio River Valley. By daybreak a secondary area of low pressure was developing in the vicinity of Chesapeake Bay, and would become the primary low pressure center by midday as it neared Long Island. The marginal temperatures of the early season air mass and easterly winds bringing warmer marine air inland meant that much of the initial precipitation fell as rain. By late afternoon precipitation type in marginal areas was flipping to snow as the precipitation rate increased. Snow continued into the late evening before winding down. It was a wet, heavy snowfall that was elevation dependent with small changes in elevation having significant differences in amounts.
