Recent IMD forecasts and model guidance point to thundershowers or increased cloud cover arriving over Uttar Pradesh on June 15, driven by moisture incursion and a strengthening monsoon trough, which should limit peak solar heating and produce afternoon convection that caps maximum temperatures. This explains the tight clustering around 37–38 °C in trader pricing, as even modest rainfall or persistent cloud can suppress readings by 2–4 °C relative to recent heat-wave values near 44 °C. Key variables differentiating the narrow outcomes include the precise timing and coverage of any showers, boundary-layer humidity, and low-level wind speeds that enhance or reduce evaporative cooling; clearer conditions would favor the upper end of the range while widespread convection would anchor readings near or below 37 °C. Updated IMD short-range guidance and satellite trends over the next 24 hours remain the decisive inputs.
