...SUMMARY...
THE NATIONAL WEATHER SERVICE IN WILMINGTON OH HAS CONFIRMED A
TORNADO NEAR RADNOR IN DELAWARE COUNTY OHIO ON JUNE 13 2013.

A NWS DAMAGE SURVEY CONFIRMED A BRIEF TORNADO TOUCHED DOWN ON THE
WEST SIDE OF STATE HIGHWAY 257 SOUTHWEST OF RADNOR. THE TORNADO
INITIALLY HIT TWO BARNS...DESTROYING ONE AND HEAVILY DAMAGING
ANOTHER. ONE BARN CONSISTED OF CINDER BLOCK WALLS AND TIN/METAL
ROOFING. WHILE MUCH OF THE CINDER BLOCK COLLAPSED...THE ROOFING OF
THIS STRUCTURE ALONG WITH SOME OF THE CINDER BLOCK ATTACHED...AND
THE OTHER BARN ROOFING AND WALLS WAS LIFTED ACROSS HIGHWAY 257
WHERE MUCH OF THE MATERIAL WAS WRAPPED AROUND TREES ALONG THE
SCIOTO RIVER. SOME OF THE CINDER BLOCK WAS LIFTED/CARRIED ACROSS
HIGHWAY 257 AND DEPOSITED IN RESIDENTIAL YARDS ACROSS THE ROAD.

LARGE PORTIONS OF THE BARN ROOFING WAS LOFTED OVER THE TREE LINE
ALONG THE SCIOTO RIVER...AND DEPOSITED IN THE BACK YARDS OF
RESIDENCES ALONG RIVER ROAD...ON THE EAST SIDE OF THE RIVER...A
DISTANCE OF TWO TENTHS OF A MILE. TREE DAMAGE ALONG THE SOUTH SIDE
OF BRIEF TORNADO TRACK WAS LAYING IN A NORTHEAST
ORIENTATION...WHICH IS INWARD TOWARD THE TORNADO TRACK...WHICH
SUPPORTS THE IDEA OF A BRIEF CIRCULATION /CONVERGENT DAMAGE
PATTERN/ ALONG THE SHORT PATH.  

OTHER DAMAGE ALONG THE BRIEF PATH INCLUDED SNAPPED LARGE
TREES...COMPLETE DESTRUCTION AND LIFTING OF A SMALL SHED WHICH WAS
THROWN ABOUT 50 FEET...AND LARGE AMOUNTS OF DEBRIS WRAPPED AROUND
TREES. CORN STALKS WERE FOUND IN THE YARDS OF RESIDENCES ON THE
EAST SIDE OF THE SCIOTO RIVER...WITH THE NEAREST CORN FIELD
UPSTREAM TO BE THE FIELD BEHIND THE DESTROYED BARNS ON THE WEST
SIDE OF THE RIVER...SUGGESTING THESE STALKS WERE LIFTED FROM THE
GROUND AND CARRIED AROUND A QUARTER OF A MILE. CONSIDERING ALL
DAMAGE INDICATORS...A WIND SPEED OF 85 MPH APPEARS CONSISTENT WITH
THIS DAMAGE...WHICH MAKES TORNADO A HIGH-END EF-0 ON THE ENHANCED
FUJITA SCALE.

THE COLUMBUS OHIO TERMINAL DOPPLER WEATHER RADAR /TCMH TDWR/
CONFIRMS A STRONG LOW LEVEL ROTATION SIGNAL IN THIS AREA WHICH
FURTHER CORROBORATES THE RESULTS OF THIS SURVEY.

THE NATIONAL WEATHER SERVICE WISHES TO THANK THE DELAWARE COUNTY
EMA FOR SIGNIFICANT HELP AND CONTRIBUTION TO THE FINDINGS OF THIS
DAMAGE SURVEY.

FOR REFERENCE...THE ENHANCED FUJITA SCALE CLASSIFIES TORNADOES INTO
THE FOLLOWING CATEGORIES:
