Wider weather episode

Low pressure developed over the lower Mississippi Valley on Saturday April 14th, and then moved northeast while intensifying, reaching the southern Appalachians by Sunday morning, April 15th, and then just south of western Long Island by Monday morning, April 16th. This low became very intense, with a central barometric pressure falling below 970 millibars upon reaching just south of Long Island Monday morning. The low then headed off the New England coast by Tuesday morning.

This intense coastal storm spread heavy precipitation across the lower and mid Hudson Valley region of New York, starting on Sunday, and persisting into late Monday. Initially, the precipitation fell as a mixture of wet snow, sleet and rain, with snow and sleet more prevalent across the higher elevations. The precipitation changed to plain rain by late Sunday afternoon into Monday.

Liquid equivalent precipitation totals from this storm ranged from 3 to 8 inches. This led to widespread flooding across the lower and mid Hudson Valley region from late Sunday into Monday evening.
