The morning charts show a fortuitious amalgamation of ingredients developing over much of Kansas and Nebraska.
A boundary is obvious this morning along the NE/KS border. To the north of the boundary, surface winds are easterly. The convection that helped reinforce this boundary overnight is out of the way, so the boundary should have a chance to "cook" during the day. Meanwhile, a surface low is progged to deepen significantly during the day back around Goodland. Given these two factors, I would expect the boundary to become more diffuse, but still be strong enough for moisture to "pool" along the KS/NE border.
With the boundary in place, strong low-level isallobaric forcing directed toward the west, and a strong jet aloft from the WSW, deep-layer and low-level shear profiles should be excellent -- perhaps locally "ideal", along and north of the boundary. Thermodynamically, the "pooling" of the moisture should help lower cloud bases in the vicinity of, and north of, the old boundary. 00Z progged soundings from GRI/HSI area show an excellent thermodynamic profile for tornadoes...we will see if it comes to pass. In summary, there is a good chance that a rather large area of Nebraska along and north of the boundary will have excellent shear and thermodynamic profiles for tornadoes. Unless an unforeseen problem develops, I forecast supercells developing near the triple point and eastward along the boundary to move ENE at ~25 mph across southern Nebraska, and be cyclic tornado-producers.
Farther south along the dryline in Kansas, the cap should break again today with scattered supercells. The shear will be plentiful, but low-level shear will obviously be not quite as good as along the boundary up north. And, as yesterday, the cloud bases will be a bit high with 20-25 degree dewpoint depressions. Still, a few tornadoes will be possible down the line. It's worth noting that two of the dryline supercells yesterday put out softball-size hail, and conditions will continue to be favorable both along the dryline and northern boundary for giant hail today.
Good luck to everyone giving today a chase effort. Please be careful, it will be a zoo out there! See you out there...
