Motorists and those spending time outdoors should be on the lookout for rapidly changing weather conditions.
Airline passengers are likely to face delays as storms approach their departure, arrival or connection hubs.
A couple of storm systems will roll eastward from the Midwest this weekend. These storms will tap the high level of moisture in the region as well as a north-south temperature contrast.
Some communities will be hit with severe thunderstorms containing high winds, hail, torrential downpours and frequent lightning strikes.
Some neighborhoods and rural areas can be hit with flash and urban flooding, where streets suddenly become rivers and small streams become raging torrents of water.
Those camping along streams should remain vigilant and keep up to date on flash flood advisories as they are issued.
In some cases, a single thunderstorm can lead to flooding. In others, the cumulative effect of multiple rounds of storms can lead to high water.
During Saturday and Saturday night, the area from the Ohio Valley to areas within 100 miles or so of the Mason-Dixon line will be at greatest risk for one or more lines of severe thunderstorms.
"Areas from Cincinnati to Pittsburgh; Morgantown, West Virginia; Philadelphia; Washington, D.C.; Atlantic City, New Jersey; and close to New York City will be at greatest risk for these dangerous and disruptive storms into Saturday evening," according to AccuWeather Senior Meteorologist Kristina Pydynowski. ■
