Trader consensus on Polymarket heavily favors a high temperature of 86°F or higher in Houston on May 15 (89% implied probability), aligned with the National Weather Service forecast for mostly sunny skies and a peak near 89°F at key observing sites like Houston Intercontinental Airport. This positioning stems from a dominant upper-level ridge over Texas fostering subsidence, clear skies, and efficient daytime heating amid an air mass preconditioned by recent highs in the mid-80s and an ongoing ozone action day indicating stagnant, warm conditions. Model consensus from GFS and ECMWF runs over the past 24 hours shows little deviation, with mid-May climatological normals around 88°F providing historical precedent. Minor uncertainty persists from potential afternoon cumulus clouds or subtle Gulf breeze influences, but latest guidance minimizes these risks; watch for evening NWS forecast updates.
