Take a look at the radar from 11:30pm:
As expected Freezing Rain is increasing and as you can see there are some Lighting icons showing up. So there could be some Thunder freezing rain!! Ice Accumulations are going to be a little lower because the precip. has just started to really fire up. About .10"-.15" can be expected in the KC Area. Farther South you go, Ice accumulations will be around .25"-.50". Be careful and have a great night.
