I hadn't really looked at Monday, since I spent most of yesterday chasing around northern Illinois (saw some photogenic garden-variety thunderstorms but nothing too exciting, although I was about 20 miles south of the EF0 tornado as it occurred in Boone County, I never could catch up to it before the warning expired not that I would have been able to see anything anyway as it was a heavily rain-wrapped comma head structure and not a classic supercell).
Let's just say the 18Z HRRR is rather alarming for the OK/KS border region and points north.
