Coastal storm to swipe Northeast, New England this weekend amid unseasonable cooldown

Heavy rain will move through the Ohio Valley and western New York into the Northeast and New England through Friday. Meanwhile, a coastal storm is expected to form off the coast of North Carolina early Saturday and track up the Eastern Seaboard. Currently, this system is expected to deliver only a glancing blow to the northeastern part of the Interstate 95 corridor. Washington, D.C., New York, Philadelphia and Boston will see less than half an inch of rain beginning late Saturday afternoon, before quickly tapering off by Sunday morning. The rain will be accompanied by temperatures 10-15 degrees below average for this time of year.
