It's not subsidence. More of the issue with drier air flowing in from the east across NE IL.
Further west across the DVN this issue doesn't exist, due to less dry air at the start.
The good news is that the ARW/NMM/NSSL WRF all are much wetter and snowier than the NAM/3KM NAM.
Usually wouldn't mention them much in the winter, but might be of some use this go around.
