Official National Weather Service observations from Los Angeles International Airport (KLAX)—the authoritative station for this market—recorded a maximum temperature of 70°F at 2:50 PM PDT on April 21, 2026, driving trader consensus to 100% implied probability for the 70-71°F outcome as the market resolves. A late-season upper-level trough introduced cooler marine air, persistent stratus clouds from the marine layer, light showers, and gusty onshore winds under an NWS wind advisory, capping highs near seasonal April norms of 68-70°F per NOAA climatology despite brief midday clearing. This skin-in-the-game positioning reflects verified automated and human quality-controlled data; realistic challenges include infrequent post-finalization revisions by NWS shifting the peak outside 70-71°F, though such adjustments are rare for established readings.
