Persistent heavy rainfall and thunderstorm activity tied to the retreating southwest monsoon over Uttar Pradesh are suppressing radiative cooling and elevating minimum temperatures in Lucknow. India Meteorological Department forecasts indicate overcast skies with intermittent spells of rain or thundershowers on September 26, supporting a minimum near 22°C amid high humidity near 90% and light winds. Recent observations show a dip to 23.2°C on September 24, yet sustained cloud cover and moisture advection from easterly flows are limiting further drops. Trader sentiment clusters around 22–23°C outcomes due to these stable monsoon dynamics, while the spread to 27°C or higher reflects residual uncertainty in exact rainfall timing and any brief clearing that could alter nocturnal temperatures before resolution.
