FWIW, GFS (Pivotal) has most of WI getting 15" - 20" through 240 hours (depending on whether you use 10:1 or Kuchera). Euro only has 10:1 on the free version but it has 8"-9" with the exception of an inexplicable N-S screw zone from about Marengo, IL to Lake Winnebago.
I think it's safe to say that, all-important details aside, the zzzzzzzzzz pattern is over for most of us.
