Recent IMD short-range and extended forecasts for Uttar Pradesh highlight the key driver behind the tight clustering around 38–39°C outcomes: expected moisture incursion and partial cloud cover from a Bay of Bengal pulse or weak trough, which typically caps daytime maxima 3–5°C below peak pre-monsoon values. Current observations show Lucknow highs near 42–45°C through mid-June, but model consensus points to moderating conditions by the 17th, with official guidance emphasizing thunderstorm potential and reduced insolation. Historical June averages hover near 38–40°C, yet interannual variability from steering patterns and humidity spikes creates genuine forecast spread; traders weigh the latest morning IMD bulletins most heavily, as resolution hinges on the verified 24-hour maximum recorded at the Lucknow observatory. Updated model runs over the next 48 hours will likely refine these probabilities.
