Official National Weather Service observations from Austin Camp Mabry and Bergstrom International Airport confirm the highest temperature on April 18, 2026, peaked at 72-73°F, driving trader consensus to a 100% implied probability for this bin. Persistent cloud cover and scattered showers from a lingering upper-level trough and northerly winds—remnants of a cold front that swept through Central Texas earlier in the week—severely limited solar heating, capping highs well below the April climatological average of 81°F. This followed record-warm early April temperatures, including ties near 93°F on April 1. With automated surface observing system (ASOS) data now finalized in daily climate reports, revision risks are negligible barring rare instrument anomalies.
