Traders see nearly equal implied probabilities for 33°C and 34°C maxima in Lucknow on August 15 because monsoon conditions introduce forecast spread. Official guidance from the India Meteorological Department highlights a depression-driven moisture surge favoring scattered thundershowers and increased cloud cover, which limits daytime heating and keeps highs near seasonal norms of 31–33°C. Model consensus shows modest differences in rainfall timing and intensity, directly affecting surface temperatures via evaporative cooling and reduced solar insolation. Historical August records indicate that even brief clear spells can push readings 1–2°C higher, while heavier showers suppress them, explaining the tight clustering around these two outcomes and the lower odds assigned to 35°C or above. Updated short-range model runs and IMD bulletins expected later today will likely refine the exact peak.
