Wednesday's bow echo that traveled 600 miles from Indiana to New Jersey was a low-end derecho
It was another intense day of severe thunderstorm activity for the Mid-Atlantic region on Thursday. A child was killed in Virginia by a falling tree, and at least three people were injured in Albemarle, North Carolina when a violent thunderstorm blew trees onto homes. NOAA's Storm Prediction Center (SPC) logged 376 reports of damaging thunderstorm wind gusts in the 15 hours ending at 11:25 pm EDT Thursday night, and three of these gusts were 74 mph or greater.
SPC is now acknowledging that Wednesday's bow echo that traveled 600 miles from Indiana to New Jersey was a low-end derecho, with over 150 damaging wind reports. The most impressive thunderstorm winds from the derecho occurred in Wabash County, Indiana, where a "macroburst" produced winds of 90 - 100 mph across an area seven miles long and three miles wide, destroying three buildings and causing extensive tree damage. Total damage from the two-day severe weather outbreak over the Midwest and Mid-Atlantic will likely run into the hundreds of millions of dollars.
