Because of the alignment of winds in the upper atmosphere, the current batch of brutal Arctic cold air in the Midwest and Northeast will never touch Texas. In fact, most readings locally will be on the mild side for the next seven days. A storm moving through the Corn Belt and Mid-Atlantic region may push a weak cold front through the Lone Star State Friday. There is the possibility that boundary may stall through Saturday into Sunday, and with that stationary position may come chances for showers. But temperatures will stay out of the cold zone through early next week.
There will be a pronounced pattern shift around January 29 - 30, with a strong storm taking shape over the Texas Panhandle. As the low builds and takes aim at the Ohio Valley, a surge of Arctic air will fall in behind the system and bring heavy rain and thunderstorms to Houston. The computer models are adamant about this feature starting a week-long period of intense cold in the U.S. top the right of the Continental Divide. There is even a decent chance of a southern branch storm scenario cutting across northern Mexico and along the Gulf Coast on February 3 - 6.
But for now, Houston is on the mild side of U.S. weather.
