Bow echo/low-end derecho of June 12-13, 2013

- The event of Wednesday evening June 12th-Thursday morning June 13th can be considered a low-end derecho. While a few significant wind reports in excess of 70 mph occurred in Indiana, the lack of higher wind speeds/gusts along the entire track of the bow echo keep this event on the lower end.

- Widespread severe thunderstorms over the Midwest during the late evening, became organized into a squall line over Indiana before Midnight EDT. The line then accelerated east across Ohio, Pennsylvania and New Jersey through Thursday morning, June 13, 2013 with an average forward speed of 47 mph.

- The bow echo/derecho traveled over 400 miles in about 6 hours during its peak intensity resulting in over 100 damaging wind reports. The most significant damage appears to have occurred during the late evening across parts of Indiana.
