More Nov. tornadoes in OH, IN, PA, IL


November tornadoes aren’t unusual occurrences in the Midwest and East, but a string of tornaodes Sunday, along with associated flooding and heavy rains, did some serious damage to areas near Indianapolis, Indiana; Celina, Ohio; and Erie, Pennsylvania. No serious injuries were reported.

The above video was taken from a security camera at a restaurant in Findlay, Ohio, showing what can happen when high winds blow a storefront window right on top of patrons.

The most serious damage reported was from a cyclic supercell that impacted Blackford and Jay counties, about 65 miles northeast of Indianapolis, a line of storms that produced an EF-2 tornado and associated damage.

The National Weather Service said at least three tornadoes touched down when storms battered Indiana and injured four members of a family in Muncie, The Indianapolis Star reported.

In Northwest Ohio, Findlay High School had some windows blown out, according to the Lima News. Because of the damage in and around Findlay, school was closed for Monday. Celina City School District also canceled classes for Monday because of the storms.

Typical monthly averages for tornadoes

Illinois, Indiana, Ohio, and Pennsylvania aren’t the most active tornado states in November; that distinction goes to the mid-South (Arkansas, Louisiana, Tennessee, Mississippi, and Alabama), according to data from the Storm Prediction Center compiled by US The mid-South averages 27 tornadoes in November.

The Midwest and Pennsylvania typically get about five tornadoes every November. Last weekend’s storms—more than a dozen tornadoes were confirmed Sunday in the four states of Pennsylvania, Illinois, Indiana, and Ohio—would elevate that average a little.
