Cold Core setup for Monday March 17th?

The GFS is hinting at a cold-core setup for central KS on next Monday. A strong 500mb low (-30C where < -24C is needed!) is forecast to be near a surface low (240 close to < 200 miles separation) in north-central KS with a nice fetch of CAPE into the low. Have to keep an eye on this one!

Which brings me to this quick reference guide (ref Jon Davies):
WHAT DO YOU NEED FOR COLD CORE??
1) 500Mb upper low with < -24C temps
2) Surface low within 200 miles, preferable to the east-northeast
3) Low to mid-50's dewpoints
