Current forecast models project a daily high temperature of 86–89°F in Houston on May 22, driven by typical late-spring southerly flow and ample solar heating under partly cloudy skies, aligning closely with the 1991–2020 climatological normal of 89°F. This positions the market-implied 100% odds for 90°F or higher on firm ground, as official National Weather Service guidance and ensemble runs show minimal downside risk from cooling influences. Traders’ consensus reflects the low likelihood of significant deviations, such as an unseasonal frontal passage or widespread cloud cover reducing insolation. Resolution hinges on the official high at William P. Hobby Airport; only an abrupt model shift or measurement anomaly below the threshold could alter the outcome before close of day.
