Persistent cloud cover, widespread thunderstorms, and high humidity from active monsoon conditions are anchoring trader focus on a 22–23°C minimum for Lucknow on September 26. India Meteorological Department forecasts list a 22°C low alongside 24°C high, with 40–50 km/h gusts and heavy rain likely, limiting nighttime radiative cooling. Recent observations show overnight lows near 22°C under similar overcast skies, while model consensus points to minimal diurnal range due to saturated boundary-layer moisture. These factors explain the tight clustering of market-implied odds around 22–23°C, with lower probabilities assigned to cooler or warmer thresholds absent major forecast shifts before resolution.
