Official observations from the National Weather Service at William P. Hobby Airport (KHOU)—the market's designated resolution source—confirm Houston's maximum temperature on April 30 reached 88-89°F, yielding Polymarket's 100% trader consensus on this outcome backed by real-money positions. Persistent cloud cover and scattered showers, as detailed in NWS Houston-Galveston advisories, curtailed solar insolation and daytime heating despite a humid southerly airflow and near-record potential in the warm air mass. This matches pre-event forecast consensus from NOAA models like HRRR, which projected capped highs amid precipitation risks. Realistic challenges are minimal but could involve rare post-processing revisions to quality-controlled data or disputes over peak-hour sensor readings; final NWS climatological summary expected soon will solidify resolution.
