The kind of look we'd be dealing w/ if this trended favorably is something along the lines of Jan 1992, which produced a sizable snowstorm along the I-20 corridor. Notice the cut off upper low is nearly attached to the trough and sitting over SW TX and northern Mexico.
The one thing we don't have that we had in 1991-92 was a strong El Nino. The additional westerly momentum El Nino pumps into the southern branch of the jet via central Pacific convection encourages these cut off upper lows over the southwestern US and northern Mexico to be more progressive and come out a little quicker.
