The storm system responsible for severe weather over the Central states for nearly a week will shift into part of the Eastern states this weekend.
The storms will continue the risk for damaging wind gusts, large hail, frequent lightning and torrential downpours. A few of the strongest storms could bring a tornado with the greatest chance from the mid-afternoon to the early evening hours.
Some communities can be hit hard with power outages, downed trees, flooding and property damage.
During Saturday, the threat for severe weather will reach from part of the eastern Great Lakes to portions of the Tennessee and lower Mississippi valleys, as well as northeastern Texas.
During Sunday the risk for strong to locally damaging thunderstorms will reach from northern Maine to West Virginia and northwestern Virginia.
By the end of the weekend, there is a risk for localized severe weather reaching the I-95 cities from Boston, to New York City, Philadelphia and Washington, D.C.
The storms and the front that follows will mark an end to the buildup of heat and humidity in the Ohio Valley, Great Lakes and the East.
Please keep an eye out for rapidly changing weather conditions this weekend. The majority of the thunderstorms will occur between 2:00 p.m. and 10:00 p.m. However, there will be some exceptions.
If you can hear thunder and are outdoors, you are at risk for being struck by lightning. Move indoors, away from windows. Golf carts and picnic pavilions do not offer adequate protection from lightning. If you can only seek shelter in your vehicle, move to an area away from trees. Avoid setting up camp along small streams, which can rapidly rise during downpours. Don't drive through flooded roadways. By doing so you are not only putting yourself and occupants at risk, but also your would-be rescuers.
