Persistent high pressure and a regional heat dome over Central Texas have sustained mostly sunny skies, light winds, and minimal cloud cover, supporting afternoon highs near or above 103°F in recent National Weather Service guidance. These conditions, combined with above-normal seasonal baselines for Austin in mid-to-late August, underpin trader consensus favoring the 112°F-or-higher bucket at 50% implied probability as the dominant outcome. Model runs show limited cooling potential before August 21, though divergence in ensemble guidance and any unexpected moisture intrusion could shift results toward the clustered 98–111°F ranges now each priced near 26%.
