Trader consensus on Polymarket has locked in at 100% implied probability for a Houston high temperature of 70-71°F on April 20, backed by preliminary observations from the resolving station, William P. Hobby Airport (KHOU) via Weather Underground, confirming the peak reached within that range under overcast skies and lingering cool air mass. National Weather Service data aligns, with late-afternoon readings around 64-66°F at nearby Intercontinental Airport (KIAH) and NOAA's citywide average of 70.3°F—5.3°F above the 1991-2020 mean but far below typical April highs near 79°F—reflecting post-frontal northerly flow and cloud-induced suppression of daytime heating. Scenarios challenging this include rare data revisions from automated sensors, though final certified reports expected soon reinforce the positioning.
