The chill you awaken to on Thursday will quickly dissipate, and for the most part the Houston area forecast is quite mild, and getting milder. Arctic air will dominate the Midwest and Northeast, likely staying away from Texas. But the rise in temperature will be slow. And as the atmosphere warms, the constant southerly flow that sets up off of the Gulf of Mexico will return higher dewpoints to southeastern Texas. Enough energy may advance via the subtropical jet stream (using the equatorial Pacific Ocean as a moisture source) to increase chances for clouds and a few showers off and on from Saturday through the middle of next week.
I suspect that most of our forecast through the next 12 days will be in the mild or warm spectrum. There are no signs of high-latitude blocking, and tropical forcing mechanisms are oriented in such a way as to deliver moisture to Texas and adjacent states while not enhancing the amplitude of the jet stream. It would appear that the vigorous storm sequence across the northern Pacific Ocean will be the biggest player in the extended outlook. Believe me when I say that the synoptic charts for the 11 - 15 day period look more like April than February. The computer models seem to be pointing toward a particularly menacing storm and trough complex tracking from the Front Range of CO to the Eastern Townships Of QC around February 9 - 13. If what I am seeing is correct, there could be a genuine severe weather event or outbreak from the lower and middle Great Plains through the Corn Belt and Old South. With snow and ice chances limited to the likes of Minneapolis MN and Sault Ste. Marie MI.
Maybe cold air will filter in behind that system, but I emphasize that for Texas and much of the eastern two-thirds of the U.S., winter can be compared to bread heated for 60 seconds. It's toast.
