I think a good place to start the bidding is 5-8". Place over/unders on that.
I'm a bit worried since this could sort of be a "dying" system, that dry air could get wrapped in on Thursday and cut stuff down.
Eastern Nebraska would get hammered. I'd probably be more comfortable getting to double digits for amounts around Omaha....maybe Atlantic/Denison/Carroll.
But this thing doesn't move onshore until Tuesday, so those numbers really don't have a lot of significance or meaning at this point.
There is still potential there for totals to go over that in Des Moines, but that's where my gut is going right now.
