20Z Update
No changes to the ongoing forecast are needed. See the previous discussion for additional details.
A large upper trough will deepen over the Rockies and High Plains this evening, with large-scale forcing for ascent spreading across much of TX/OK. Forecast soundings in this area show sufficiently steep mid-level lapse rates and MUCAPE > 0 to support occasional thunderstorms. This includes parts of western north TX and southern OK where freezing p-types are anticipated.
Over south TX, the main cold front will be surging southward into a moist air mass with dewpoints in the 60s. Several model solutions suggest the development of a few thunderstorms along the front - mainly after dark. While a brief tornado or strong wind gust cannot be ruled out, rapid undercutting of the front is expected to limit the overall severe threat so no probabilities have been added.
