Official measurements from the National Weather Service at Houston's primary reporting stations confirmed a daily high temperature of 90°F or above on May 16, producing the market's overwhelming 100% implied probability for an 88°F-or-higher outcome. This result aligned with seasonal warming trends and a persistent high-pressure ridge that suppressed cloud cover and allowed strong solar heating under light southerly flow. Historical May normals near 87°F provide context for the elevated reading, while model consensus in the preceding days had already converged on upper-80s to low-90s conditions. Only an unforeseen post-event data revision or station-specific anomaly could alter the recorded value, though such adjustments remain rare once initial quality-control checks are complete.
