The coming snow


A major winter storm will affect the I-95 corridor late Wednesday night into Thursday with significant travel disruptions and potential power outages.

 
The combination of cold air moving in and storm coming in from the Southwest will combine to bring a substantial winter event beginning late tonight in the DC – Philly corridor and during Thursday in the Northeast. Any rain overnight will quickly change to a heavy wet snow late tonight into Thursday morning. In DC and Baltimore City, the recent warm weather may limit accumulations to a couple inches of slush or less, but just north and west accumulations will increase rapidly with 4-8 inches expected in northern Maryland and much of PA including Philadelphia. The snow should end in DC / Baltimore by mid-morning.

 
Farther north the storm will last into Thursday afternoon, with accumulations ranging from 8-12 inches across northern New Jersey and Southern New England including NYC and Boston. The storm will end later in the afternoon in the Northeast.

 
The combination of strong winds and heavy wet snow will lead to numerous power outages from Eastern PA into Southern New England. The highest probability for outages is in and around the NYC area and extreme southern New England.

 
Temperatures will plummet well below freezing later tomorrow; turning any standing water to ice. Some blowing and drifting snow may occur into Friday.
