NWS consensus models, particularly the HRRR and NAM, indicate persistent 850mb thermal advection, stabilizing surface temps for Austin on April 29. Peak afternoon boundary layer mixing, under a dominant ridge, pegs the high at 82-83°F. While 84°F remains an edge-case risk from intense insolation, the tight clustering across multiple forecast runs implies this specific range is the modal outcome, signaling strong agreement. This is a high-confidence YES. 92% YES — invalid if the official Austin-Mabry highest temp records outside 81.5-83.9°F.
