CANADA. SIGNIFICANT DEEPENING SFC WAVE TO TRACK EAST ACRS THE SRN
GREAT LAKES WITH ASSOCIATED STG COLD FRONT DROPPING TO NEAR THE
I-71 CORRIDOR BY 12Z. VERY STG 925MB JET AROUND 50KTS WL PROVIDE
GOOD FORCING ALONG WITH CAPES BETWEEN 1000-1500 J/KG. THIS FORCING

TORNADOES WL ALSO BE POSSIBLE MAINLY ACRS NRN HALF OF ILN/S FA.
HAVE BUMPED UP POPS TO CATEGORICAL TO ACCOUNT FOR THIS CONVECTIVE
ACTIVITY.
WITH THE PASSAGE OF THE COLD FRONT TO THE SOUTHEAST...DEEP MSTR AND
INSTBY EXISTS THE REGION THIS MORNING AND THEREFORE WL END MENTION
OF SHOWERS AND THUNDERSTORMS. A FEW POST FRONTAL SHOWERS ARE NOT OUT

The Cincinnati radar (KILN), 95 km away, was scanning. The volume nearest the first event began at 09:34 UTC.
2 thunderstorm wind, 1 tornado. Local standard time, as filed.
Trees were reported down due to damaging thunderstorm winds.
Damage from the tornado consisted of several large tree limbs and trees down. Light structural damage occurred to several homes near State Route 38 and Timberview Drive. This damage included the loss of shingles and siding. The most significant damage occurred to a home along State Route 38 which suffered near total roof loss. Based on the damage, wind speeds were estimated to be around 85 miles per hour.
Several five inch diameter trees snapped in half at their trunks.
