Notice a second low is dropping southeastward into NW Missouri at the same time. This is a reflection of a strong upper air trough that is digging southeastward from Canada. The problem here is that the systems are far enough apart that they basically behave as separate entities. The wave will move out ahead of the energy which would prevent this from becoming anything major.

The European model is slower with that upstream energy by about 24 hours as it swings that system...READ MORE AT http://www.meteorologistjoecioffi.com/index.php/2017/12/02/weather-models-cold-active-long-range/
