Severe WX on Saturday

Saturday looks like a real break-or-bust kind of day for NE Kansas/SE Nebraska; strong cap (that NAM erodes by 0Z), fairly strong instability, tons of shear. SFC low detaching from trough and sitting in central Kansas; not sure if it's trying to render up an attached warm front in E KS or not. NAM breaks precip out in NE KS and SE NE at 0Z, so my hopes are up. It would be interesting to try chasing NW flow storms for a change.

Winds, 850 on up are turnin' like mad (bulk shear of around 50kts), with a good LLJ and a shortwave showing up on the 500 and 700. Hell, there's even some diffluence in the 250 right along the NE KS/SE NE border.

TD's nearing 70-75, if the NAM is to be trusted. And the juice goes all the way up to 500mb.

This looks like a pretty awesome-sauce kind of day. Hey, if nothing happens, at least I'll get to explore another side of Kansas. I've seen enough of the west in the past month. :)

Windy,

The only concern for Saturday in that region from my perspective is the capping inversion is going to be really strong. We are going to need a very diurnally heated low level environment with the Convective temps being around 83-86 or so most likely. I do think things will break as the impressive shear jets nose in with the s/w axis. Happy tornado hunting. :)
