Models?! We don't need no stinkin' models! How about a big paper map, some blue pencils and a lot of slide rules (ok maybe a bit of an exaggeration)
Looking at some newspapers in '89, an article on Dec 20 in the Dallas Morning News (a Wednesday) predicted highs in the low 30s and lows in the mid teens for Friday and Saturday. The following day a more alarming article came out predicting a much more severe cold outbreak, with highs as cold as 12 on Friday with a low around 0 Saturday morning. This proved to be quite accurate but it didn't get published until the day before the front arrived.
Similar articles on the 21st in the Austin and Houston papers were also published about the severity of the upcoming cold wave. They were a couple of degrees too warm but got the general idea right.
If this was published on the 21st that means the NWS was sounding the alarm on the 20th, a whopping 2 days ahead of the front. To their credit, they did correctly predict that the upper air patterns would change dramatically after the cold outbreak with a warmup to follow.
So yeah, we've come a long ways.
As for the upcoming outbreak, the models have been predicting for days now a very cold outbreak for the NW US and it is looking more and more like that's going to happen in some form or fashion. What the computers are having more trouble with is where it goes after that. To me it looks a little far to the west to be the dreaded "Straight-Down-The-Front-Range-Blue-Norther-MOAF" event for TX but it's certainly worth monitoring. Will probably be cold, just nothing of biblical proportions (at least for us). The maps for Feb 2011 were a lot scarier, that I remember.
