The same storm system responsible for producing violent and deadly thunderstorms in Oklahoma recently will move into the heavily populated Atlantic Seaboard through Thursday night.
The nature of the storms will change somewhat from producing tornadoes to more of a straight-line wind gust, hail and flash flooding event. However, there is a chance that a couple of the strongest thunderstorms will produce a brief tornado.
The risk for damaging and dangerous thunderstorms is forecast to extend from northern Virginia to eastern New York state and portions of western New England. Much of this area will be in a sea of warm, humid air as a cold front moves in from the west and clashes with this air.
While the worst of the storms will fire along and west of I-95, any activity that makes it to the Jersey Shore north into southern New England will be very slow-moving, and localized flash flooding is possible.
People from Washington, D.C., Baltimore, Md., Wilmington, Del., Philadelphia, New York City and Albany, N.Y., should be prepared for travel problems, sporadic power outages, frequent lightning strikes and urban flooding into early Thursday night.
The leading edge of the storm system brought a plethora of dangerous thunderstorms to parts of the same region on Wednesday. There were nearly 150 reports of severe weather from far eastern Tennessee northward across West Virginia, Pennsylvania and New York state.
In some spots north of Syracuse, hail as large as tennis balls fell to the ground, smashing wind shields and denting cars. Further south, a man was injured by falling hailstones in Roscoe, N.Y. as he tried to seek shelter in a bath house at a camp ground.
If you will be out and about, be sure to keep a close eye to the sky for threatening weather. Thunderstorms will develop quickly in the warm and soupy air, and you might be caught off guard if you are not prepared.
Know the difference between a watch and a warning. A watch means that an area is being monitored for dangerous weather. A warning means that dangerous weather is imminent.
Also, for those that will be spending any time near water or out at the golf course, keep in mind that lightning is one of Mother Nature's most dangerous killers. If you can hear thunder, you are close enough to the storm to be struck by lightning, even if the sun is still shining.
As this thunderstorm activity continues to gradually converge along the East Coast Friday into the first part of the weekend, a coastal storm will take shape.
