You've got that right for central Texas. The national weather service said the dome of high pressure may move north by early next week, and I hope it does and stays away.
I e-mailed David Finfrock about this weather pattern, as I do on occasion, and he’s great about answering promptly. He had no answer to why low pressure storm systems and other weather mechanisms rush right on through from west to east, but these high pressure “domes” just dig in and become semi-permanent in Texas. I always thought all weather moves from west to east generally. I think there is something more supernatural about this.
