Recent model runs and official guidance from Chinese meteorological sources show a frontal passage and increased cloud cover limiting insolation over Wuhan on September 22, keeping daytime maxima in the mid-20s °C range despite seasonal norms near 27–29 °C. Ensemble forecasts indicate 26–28 °C highs with 30–50 % rain probability, where thicker stratiform clouds and evaporative cooling from scattered showers could cap temperatures near 25 °C or below, while clearer breaks might allow brief warming to 28–29 °C. Low-level northerly flow advecting cooler, moister air further suppresses peak readings relative to recent sunny days. This spread across numerical weather prediction outputs and observational uncertainty explains the tightly clustered market-implied probabilities around 23–29 °C. Updated short-range model guidance and local station observations in the next 24–48 hours will likely narrow the range.
