Official National Weather Service observations from the automated surface observing system at Los Angeles International Airport (LAX) confirm the highest temperature on April 27, 2026, peaked at 66°F around 2 PM local time, driving 100% market-implied probability for the 66-67°F outcome as traders price in the verified measurement. Persistent marine layer clouds and cool onshore flow from the Pacific suppressed daytime heating below the April normal of 69°F, aligning with pre-event NOAA forecast model consensus for mid-60s highs amid a stable high-pressure ridge offshore. While post-issuance data revisions from quality control are possible though exceedingly rare with corroborating hourly METAR reports, no such changes are anticipated, securing resolution.
