The colder air pouring into Texas will prove to be transient. Over the next few days Arctic air will relax, basically confined to much of the Midwest and Northeast. But before moderation revisits the Lone Star State, we will have a very cold Wednesday night and Thursday morning. Fair skies, diminished wind and low dewpoints may enable the freeze line to sag down close to the Gulf Coast.
Despite the cold night ahead, I am convinced that winter is finished in the Houston area (and, to a large degree, the entire southern and eastern quadrants of the U.S. It may be possible that one or two intrusions of Arctic air will drop out of Canada between now and mid-February. However, the lack of any viable high-latitude blocking signatures in or around North America (despite so many computer models saying otherwise) would suggest that Spring gets an early, and very warm start.
As an example, the warming trend setting up this weekend will carry strongly into the following week, with 60s, 70s and finally 80s likely to be in play each afternoon. We may be in better shape for rainfall potential during the next few months than was the case two years ago, if only because nearby tropical forcing (eastern equatorial Pacific Ocean) could be lined up to deliver moisture and energy to much of Texas. many of the analogs to the current pattern suggest an unusually warm, humid pattern locally with lots of thunderstorms.
