Official measurements from National Weather Service stations in Los Angeles on May 16 recorded a daily high temperature in the 68-69°F range, consistent with ensemble forecast models that projected stable springtime conditions under a weak high-pressure ridge and light marine layer influence. This outcome aligns with regional climatology, where May daytime maxima typically cluster in the upper 60s absent strong offshore winds or anomalous warming. Trader positioning reflects this verified data release, with minimal odds on higher thresholds due to the absence of heat advection or clear-sky intensification signals in recent model runs. Resolution criteria based on official station readings leave little room for revision unless post-analysis adjustments occur at primary monitoring sites.
