This is going to be a wild day. A mesolow is expected to develop and move across lakes Erie and Ontario. South of that low, the low-level jet at 50+ knots will enhance downdrafts and also increase helicity. That means we could see significant wind damage from eastern Ohio all the way to Vermont with areas form central Pennsylvania to central New York in the zone of the more concentrated are of wind damage. Winds may gust over 70 mph in some of the storms and a few tornadoes may occur as well. The Rapid Refresh and 4km WRF both indicate an meso low develops with a squall like and supercells south of that meso low. Boaters on the lakes should be careful as the storms may produce wind gusts over 50 knots and high waves on the lakes as the meso low moves through.
