...SUMMARY...
A NATIONAL WEATHER SERVICE DAMAGE SURVEY FOUND EVIDENCE OF A WEAK /EF0/
TORNADO WHICH INITIALLY TOUCHED DOWN ON THE SOUTH SIDE OF HIGHWAY 550 WHERE
SEVERAL BARNS WERE HEAVILY DAMAGED WITH ROOFING MATERIAL THROWN ACROSS 
HIGHWAY 550 INTO ADJACENT PROPERTIES ABOUT 1/4 MILE DOWNSTREAM. FROM THERE,
A CONSISTENT SWATH OF ENHANCED TREE DAMAGE WAS FOUND ALONG A NEARLY 6 MILE
CONTINUOUS PATH ACROSS US HIGHWAY 35, COUNTY ROAD 125 (UNION LANE), EGYPT PIKE,
STATE ROUTE 207, AND STATE ROUTE 104. WITH THE ENHANCED SWATH OF DAMAGE NOT 
FOUND ON THE EAST SIDE OF THE SCIOTO RIVER, IT IS EXPECTED THAT THE TORNADO
LIFTED SOMEWHERE IN THE SCIOTO FLOOD PLAIN.

THIS TORNADO MAY NOT HAVE BEEN IN CONSTANT CONTACT WITH THE GROUND OVER THE ENTIRE
LENGTH OF THE PATH, AND WAS ALSO CLEARLY EMBEDDED WITHIN A MUCH LARGER /2-3 MILE WIDE/
SWATH OF ENHANCED STRAIGHT LINE DAMAGE. DESPITE THIS, ENOUGH INDICATION OF
A TORNADO WAS SEEN IN THE DEBRIS WITH LIFTED ROOF PANELS FROM A
FEW BARNS AND OUTBUILDINGS, AS WELL AS CONVERGENT FALL PATTERNS 
TO THE LARGE NUMBER OF TREES THAT WERE TAKEN DOWN ALONG PORTIONS 
OF THE PATH. 

DAMAGE WAS CONSISTENT WITH WIND SPEEDS UP TO 75 MPH.  

THE NATIONAL WEATHER SERVICE WOULD LIKE TO THANK THE ROSS COUNTY
EMERGENCY MANAGEMENT AGENCY FOR ASSISTANCE AND SUPPORT IN THIS
SURVEY.
