Watch Friday's #derecho  on radar from start (Iowa/Illinois) to finish (coastal Mid-Atlantic).  

Take note of how the storms bow out with the highest winds found at the apex of the bow. Top wind speeds from Friday's derecho were clocked at 80 to 90 mph.

This radar animation spans over roughly 14 hours.
