SPC has a slight risk out right now for parts of western Kansas and for a majority of Nebraska during the day on Friday, the Day 3 outlook mentions of possible supercells.
The new 12Z run of the NAM shows a bullseye CAPE value of up to 3500 J/Kg and a LI of -6 near Oberlin, KS running up to McCook, NE. Dewpoints into the lower 60's can be found along and east of this line. However, 500mb winds are low, 30-40 knots, but I think still enough to sustain thunderstorm/supercell thunderstorm development.
Although the major show is progged for the weekend, I feel this day could have some potential, as well. Graphic for this forecast can be found on the "My Chase Forecasts" link on my signature line.
