Official IMD forecasts for Lucknow project a 26°C minimum on August 22 amid active southwest monsoon conditions, with generally cloudy to overcast skies and spells of rain or thundershowers. Persistent cloud cover restricts nocturnal radiative cooling, while elevated humidity and scattered precipitation moderate overnight lows, keeping recent observed minima in the 25–27°C range consistent with seasonal norms. Global and regional model consensus supports this band, though shifts in rain timing or intensity could alter the exact low by 1–2°C. Traders have priced 26–28°C outcomes highest to reflect this guidance, with lower probabilities on outliers due to inherent forecast uncertainty and local effects; fresh IMD updates or model runs will likely refine positioning before resolution.
