The market-implied odds reflect official observations confirming a daily high temperature of 90-91°F in Miami on September 5, recorded at primary National Weather Service stations such as Miami International Airport. This outcome aligns with verified surface data amid typical late-summer atmospheric conditions, including warm Gulf moisture and light steering winds that limited further heating or cooling. Trader consensus, backed by real capital, has converged sharply on this narrow bin due to the precision of hourly meteorological measurements and the absence of model or observational discrepancies. Rare post-event revisions to station data could theoretically shift the result, though historical patterns indicate such adjustments remain small and unlikely to move the high outside 90-91°F.
