The closely matched market odds around 29–31°C reflect ongoing monsoon conditions across northern India, where increased cloud cover, high humidity near 80–95%, and scattered thundershowers are expected to moderate daytime heating in Lucknow on August 18. Official forecasts from sources like the India Meteorological Department and numerical models consistently indicate a maximum near 30–31°C amid overcast skies and light winds, with afternoon precipitation likely limiting peaks compared to clearer pre-monsoon days. Minor variations in shower timing or intensity across ensembles create the tight clustering, as even modest differences in insolation or localized convection could shift the observed high by 1–2°C. Traders are monitoring the next IMD update and high-resolution model runs for any late adjustments before resolution.
