Summary of November 5, 2017 Tornado Outbreak

 

Weather Synopsis

A cold front moved across the Ohio Valley and southern Great Lakes on the afternoon of Sunday, November 5, 2017. Unseasonably warm and humid air was in place across the region ahead of the front. The cold front gradually progressed across the Ohio Valley and thunderstorms initiated and swept east ahead of the front. The storms formed in a very strong wind field and allowed the storms to move very rapidly east at speeds of 60-80 mph. Some storms became tornadic with over a dozen tornadoes produced across northern Ohio and NW PA. A large macroburst formed and swept east just south of Cleveland and produced winds in excess of 100 mph.

National Weather Service Survey Teams were dispatched across the area on November 6 and 7 to survey damage from the severe weather outbreak that occurred on November 5. The NWS in Cleveland has confirmed 14 tornadoes across northern Ohio and northwest Pennsylvania. A list of the tornadoes and a map can be found below.
