Recent National Weather Service observations and forecast model runs for May 21 confirmed a daily maximum temperature of 72–73°F at the primary Los Angeles reporting station, aligning with typical late-spring marine layer influence that caps daytime warming near the coast. This outcome reflects standard climatological patterns for the period, with afternoon highs moderated by onshore flow and persistent low clouds rather than anomalous heat advection. Trader consensus at near-certainty levels incorporates the final climatological report criteria, including exact timing of the peak reading and station-specific thresholds. An unexpected clearing of the marine layer or a late-day temperature spike from offshore winds could still shift resolution if official data revisions occur before settlement.
