Recent forecasts from the India Meteorological Department and global models indicate persistent heatwave conditions across eastern Uttar Pradesh through June 24, driven by a strong heat dome, dry northwesterly winds, and delayed monsoon advance, supporting trader emphasis on 40°C and 41°C as the most probable peaks for Lucknow on June 21. Current observations show daily maxima near 44–45°C in recent days, with June 21 projections clustering around 41–46°C depending on the model run, though some guidance suggests modest moderation from increased humidity or localized cloud cover. These factors position the 39–41°C brackets as leading outcomes, reflecting the balance between ongoing anomalous warmth above the seasonal 39°C June average and uncertainty in exact steering patterns or convective development ahead of the June 22–24 forecast updates.
