Sunday’s Severe Weather Threat
Saturday is going to be warm and dry. A high pressure system will dominate the Northeast.
However, things will change as we head into Sunday evening. Rain will move into the region early Sunday. High PWAT values will support downpours creating a minor flash flood threat. As we head into the afternoon, the storms will intensify. 
North Carolina to NYC will needs to be prepared for severe weather. The greatest threat stretches from Raleigh, NC to Philadelphia, PA. These areas can expect multiple severe warned cells capable of producing hail, damaging winds and a few tornadoes. Other locations inside the Severe T-Storms zone can expect a much more limited severe threat.
NWS SPC currently has portions of the Mid-Atlantic under an enhanced risk meaning numerous severe storms are possible.
Understanding severe thunderstorm risk categories is very important because it can help you know what to expect.
