Meteorologist Steven DiMartino of private forecaster NY NJ PA Weather wrote in a new report Thursday that the winter storm will dump accumulating snow across the Mid-Atlantic and Northeast from Friday afternoon through Saturday.

Here is DiMartino's forecast, which suggests that travel disruptions could occur up and down the I-95 corridor from Philadelphia to Boston:

Timing: Snow develops Friday between 3-6 PM, becomes steady after 6 PM. Mixed precipitation develops after midnight in several zones, with a change back to all snow by early Saturday morning. Snow showers may linger through late Saturday morning.

Heaviest impacts: Interior parts of New York and nearby areas could see 6-10 inches of snow or sleet.

Moderate snow: Portions of southern New England and nearby regions may receive 3-6 inches.

Mixed precipitation zones: Areas around Philadelphia and central Pennsylvania face snow changing to sleet or rain, with 1-4 inches of snow and up to .05-.25 inches of ice, raising the risk of slick roads and power issues.

Farther south: Snow may briefly change to rain, with lighter accumulations.

Coastal New England: Lighter snow showers, generally 1-3 inches.
