Obviously will have to wait a while to get into specifics, but the severe setup early next week once again looks to have an extensive plume of steep mid-level lapse rates to work with.
I haven't looked into this, but I'd have to think that the extreme lack of snow and dry conditions out west tilts the odds in favor of more frequent/robust EML discharges farther east. It makes sense conceptually, as the lack of snow and dry conditions out west would tend to result in more efficient warming out there, which then gets transported (aloft) to the east.
