Breaking the waves down for Toledo Metro, I'm thinking 2-3 for wave #1 and 7-9 for wave #2 for a total of 9-12. I came to this conclusion by taking the average qpf of all models minus the highest (NAM3k) and lowest (GEM) which ended up being 0.62" and a ratio of 15-18:1 overall.
Looking at trends there should be a WWA for wave #1 and a WSW for wave #2.
