I know it is rather late, but tomorrow is looking like a shaky but chaseable day in Central/Eastern Nebraska as well as Kansas. GFS is showing an unstable atmosphere with a sufficient amount of wind shear and helicity values 230+ in Northeast Nebraska. The NAM models are showing that there will be less lift in the atmosphere, but soundings are looking rather impressive for this low forecasted event. I don't know 100% if my forecasting is correct, but I wouldn't be surprised if the risk increases and tornadoes form along the boundary. That is my opinion, and I'd love to see other's opinions and thinking.
