It's also very far south almost to Cabo with the base of the ULL. This is what I was hoping the trend would be eventually.

You need a warm nose in some form of fashion for moisture transport. That's what overruning precipitation is, warm moist air going over cooler air below. Higher the QPF involved the warmer the moisture transport from a tropics and subtropics that's just physics. There's a Goldilocks zone somewhere around maybe a quarter inch to 3/4 in of QPF where it's just enough to not overwhelm but not too little where is dry. Just a basic layman's, there's a lot more nuances involved at the upper levels. Can they overestimate yes that means the model is too wet and the colder surface wins vice versa.

So trends are looking like what for DFW?

This seems to be plausible given the runs today. If the nam is right on the faster front, then we should see the bulk of the qpf falls as sleet, with a few inches of snow on top at the end. I wonder what ratios could be in play by Sunday given the temps, would be cool to see a 50/50 split between sleet and snow accumulations, but I’m getting ahead of myself here.

Very low heights across the eastern US starting out in the plains extending to the Atlantic Ocean. This 500 millibar configuration is snowy historically for the month of February possibly one of the most highest correlated of our analogs. You're talking stuff like February 2010 and 1978 in terms of storms and quality of cold air. Just something to keep in mind as this period continues to trend this way.

Lower average heights means the atmosphere is generally colder than normal. You start cold, it will likely be cold when systems cross, just a better playing field. Surface can go through ebb and flow but mid February likely has deeper cold to work with above.
