Hello! Just finished looking at the available observational and model data for today and I think we'll initially head towards York, Nebraska. A cold front will move in from the north-west through today but should become somewhat more slow-moving as it approaches SE Nebraska. A modestly moist airmass ahead will yield CAPE values to around 1500-2000 J/Kg by mid-late afternoon, and most models break out precip along and behind the front. A few cells may manage to develop just ahead of the front too. Large hail and winds will be the main threats, but an isolated tornado or two is possible, especially with more discrete development early on. The whole lot should transition into a line this evening, with further thunderstorms likely north of the front tonight.
