My favorite hook echo image this year from the 6/26 storm that impacted Adams, Highland, Scioto, and Pike Counties. Despite its impressive appearance, it did not produce any tornadoes.
I have compiled a gallery of radar imagery from each tornado warned storm (as well as those unwarned storms that resulted in tornadoes) in Ohio in 2015. There were a wide variety of different radar signatures; some of which allow one to easily identify where the rotation may be, others make the job nearly impossible, even with the aid of velocity imagery. In order to compile these, I used the Iowa Cow website to look up tornado warning and LSR dates and times, and then downloaded radar image files from the National Climate Data Center (NCDC) and viewed them using the Weather Climate Toolkit, which is free to download from the NCDC. I will later add in a page including more detailed radar imagery for each of the seven confirmed Ohio tornadoes this year.
