Scattered showers and severe storms will bring damaging winds and 1 to 3 inches of rain from Harrisburg east through New York City and into Boston, with Sunday morning flight delays likely at JFK, LaGuardia, Newark and Boston Logan. Damaging winds are the main threat, capable of knocking down trees and power lines across the region. Travel will take the biggest hit. Those major hubs all sit in the storm path, and the Sunday morning hours look like the worst window. Drivers should plan on slow going along the I-95 corridor as downpours cut visibility and gusty winds buffet high-profile vehicles. If you have plans this weekend, build in extra time, check your flight status before heading to the airport and stay off the roads if storms are moving through your area.
