Which Weather Warning is issued the most in northern Ohio?

The Iowa https://mesonet.agron.iastate.edu/ is a fantastic resource for looking up past weather data. Warning: The site can suck you in so plan on spending some time bouncing around the different archives and graphical tools.

One element I found very interesting was the plotter that allows you to plot the NUMBER of specific types of watches and warnings PER MONTH for each NWS office.

How frequently are specific watches and warnings issued out of the NWS Office in Cleveland by month?

Tornado warning high months include MAY 1995, AUGUST 1997, JUNE 1998, NOVEMBER 2002, JUNE 2010, MAY 2014  (NOTE: Warning issuance changed from a county based system to storm based system for specific county areas in 2007)

TORNADO WARNINGS

Severe Thunderstorm Warning high months include: JUNE 1994, JUNE 1998 (HIGHEST), JULY 1999, JUNE 2008 (NOTE: Warning issuance changed from a county based system to storm based system for specific county areas in 2007)
