Lowest temperature in Boston on Jul 4, 2026?

Prediction market odds often diverge from traditional weather forecasts because they reflect real-money incentives and live trader conviction rather than model-based estimates alone. While meteorologists issue probabilistic forecasts based on atmospheric data, this market prices in trader beliefs about actual outcomes, which can incorporate local knowledge, historical patterns, and late-breaking information. Over time, prediction markets have proven competitive with or superior to expert forecasts on similar events, though near-term volatility may create temporary gaps between the two signals.
