Recent forecasts from the India Meteorological Department and international models point to minimum temperatures of 26–27°C in Lucknow on August 27, with widespread overcast skies, light northeast winds, and scattered thundershowers expected overnight. High humidity near 90% and persistent cloud cover suppress radiative cooling, while recent monsoon activity has kept observed lows in the 26–28°C range over the past week. Trader sentiment clusters tightly around 26–27°C because small differences in the timing or intensity of overnight convection, or brief clearer intervals, can shift the recorded minimum by 1°C. Updated model runs and official IMD guidance through the 27th will refine these narrow probabilities.
