Lowest temperature in Houston on Jul 3, 2026?

Prediction market odds often diverge from traditional weather forecasts because they incorporate real-time trader positioning and collective expectations rather than relying solely on meteorological models. While meteorologists publish deterministic forecasts based on atmospheric data, this market aggregates the beliefs of many participants who may weight seasonal patterns, climate trends, and historical July temperatures differently. Comparing the implied probabilities here to published forecasts from the National Weather Service or private weather firms can reveal where the market sees asymmetric risk or where consensus may be shifting.
