Heavy monsoon activity with widespread thunderstorms and gusty winds is expected to cap daytime heating across Lucknow on September 26, keeping maximum temperatures near 24–25 °C according to India Meteorological Department guidance and multiple numerical models. Persistent cloud cover, high humidity near 90 %, and northeasterly flow limit insolation and promote evaporative cooling from rainfall, preventing the higher readings seen earlier in the month. Recent observations show a sharp temperature drop under similar conditions, with official station data recording maxima around 25 °C amid comparable rain. Traders assign the highest implied probabilities to 24 °C and 25 °C because forecast spreads remain narrow, hinging on the precise timing and intensity of convective bursts that could briefly allow a 1 °C difference. Updated model runs and IMD briefings through the evening will clarify any last adjustments before resolution.
