Trader consensus on Polymarket prices 86°F or higher at a near-certain 100% implied probability for Houston's highest temperature today, driven by National Weather Service forecasts predicting highs near 89-91°F under mostly sunny skies and south-southeast winds of 10-20 mph, boosting heat indices into the 90s-100s. This reflects a persistent upper-level ridge fostering above-normal warmth, with recent observations confirming the trend—April 25 reached 86°F amid similar conditions well above the late-April climatological average of 81°F at Houston's George Bush Intercontinental Airport. Model ensembles like GFS and ECMWF show strong agreement, with minimal cloud cover or precipitation risk. Only an unforeseen marine layer surge or isolated strong thunderstorm could cap temperatures below 86°F, though probabilities remain under 1%. Hourly updates from NOAA monitoring stations will solidify observations by evening.
