Here's the thing, if the Wrf and even the NAM models to a certain degree there's going to be a train of cold air advection moving almost due north to south . There is a snow pack in northern North Dakota and just north of there in southern Canada. There's also a light snow pack in Nebraska(according to the GFS). This means that the cold air will still moderate, but probably at a slower rate. The cold air will likely be moving southward fast too. The stronger this low is, the more it can pull this cold air from the north.
Basically this is going to be a bang bang storm, but, if it's faster(It's best for the snow to happen at night) further east, and stronger, then I believe DFW will be in for a surprise. If the 0z Wrf models are correct then the cold air advection will be fairly impressive and the storm will be very dynamic.
What are the chances that WRF is correct? I know the last storm overperformed in West Texas, so there's hope?
