At 01Z, the low has moved into east-central KS just W of Topeka. The warm front extends eastward from the low through Kansas City, MO eastward to near Louisiana, MO. The dryline intersects the warm front just west of Kansas City, KS and extends SW to near Chanute, KS-Bartlesville, OK-near Shawnee, OK-just W of Ardmore, OK. Dew points in the moist sector are generally in the low 60s with MUCAPE around 2 KJ/Kg - and increasing CIN with the loss of daytime heating.
The northern cell of the two supercells that were near Columbia, MO a couple of hours ago has weakened, seemingly due to interactions with the southern cell. The southern cell has continued producing severe weather reports as it has been riding along the warm front boundary moving now into W IL. I would expect that this storm will lose supercell characteristics in the next hour or two as it moves into a less favorable environment in central IL. This storm began back in eastern KS and has completely crossed MO as a supercell - quite amazing.
Storms N and E of Kansas City, MO have moved from the weakly sheared air mass in E KS into a much more favorable area in MO and several have become supercells. I would expect these supercells to be sustained for some time as the kinematic and thermodynamic environment will favor this storm mode.
The storms further south in KS to the west of Ft. Scott will likely remain disorganized until they cross into MO and enter a more favorable kinematic environment.
In OK, a 50-knot LLJ is developing in E OK into W AR, enhancing the low level shear profile. Storms seem to be struggling with increasing CIN and decreasing convergence along the dryline.
