This is off of AccuWeather regarding the final wave:
The same storm system will raise the bar for severe weather in the Ohio Valley spanning Wednesday and Wednesday night and the central Appalachians and mid-Atlantic on Thursday and Thursday night.
On Thursday, the entire corridor from Augusta, Georgia, and Charlotte, North Carolina, to Washington, D.C., Philadelphia and perhaps New York City may be at risk for dangerous and damaging storms.
"We feel there is an enhanced risk of severe storms from southeastern and south-central Pennsylvania to southern New Jersey and northeastern Virginia," according to AccuWeather Meteorologist Brett Rossio.
This means that a higher concentration of severe storms may occur in this area.
"Should the storm strengthen quickly and there is sufficient sunshine to heat the region ahead of the thunderstorms, a violent severe weather outbreak that includes tornadoes may result," according to AccuWeather Meteorologist Jake Sojda.
A number of communities may be hit with winds that can knock down trees or break tree limbs, trigger power outages and cause minor property damage.
As the storm system slides eastward, where warm and humid air exists, there is the possibility of several tornadoes, some of which may be strong.
With the great concentration of major airports in this zone, airline passengers in the region may experience a significant uptick in flight delays and cancellations during the afternoon and evening hours.
As has been the case so far this week, a few of the strongest storms can also produce large hail.
