A cold front moving through the Ohio Valley into the Northeast and Mid-Atlantic will produce bands of severe storms from Thursday through Saturday. A complex of storms or derecho may develop across northern Iowa late Thursday and plow east into Wisconsin and northern Illinois early Friday. That system will produce widespread wind damage as winds will gust over 60 mph. More storms will develop across the Ohio Valley Friday. That area of storms could produce large hail, damaging winds and perhaps a couple of tornadoes. As the cold front moves through the the Northeast and Mid-Atlantic, it may produce more severe storms with wind damage on Saturday. Over the 3 day period, we could see well over a hundred reports of wind damage.
The other area of severe weather will be associated with the tropical system coming in this weekend. Typically, systems like this can produce tornado activity so that’s what we nee dot watch for along the eastern flank of the systems track.
