Trader consensus on Polymarket strongly favors an Austin high of 88°F or higher (75% implied probability), reflecting National Weather Service forecasts of near 91°F on May 17 amid a stubborn upper-level ridge over Texas promoting subsidence and clear skies. Recent NWS Area Forecast Discussions note unseasonably hot conditions persisting through the weekend, driven by southwest winds of 10-20 mph advecting Gulf moisture and heat, pushing heat indices even higher while keeping thunderstorm risks low. GFS and ECMWF model ensembles converge on upper 80s to low 90s, well above the May climatological average of 87°F near Austin-Bergstrom International Airport. Overnight model updates could tweak details, but current guidance underscores minimal convective interference for peak heating.
