Recent India Meteorological Department forecasts and global numerical weather models indicate Lucknow’s maximum temperature on May 18 will likely remain near or below 42 °C, driven by persistent moisture advection from the Bay of Bengal and possible cloud cover associated with a weak western disturbance. These conditions are suppressing daytime heating during the peak pre-monsoon period, when climatological averages for mid-May normally range from 40 °C to 44 °C. Recent observations across Uttar Pradesh show maximums 2–4 °C below seasonal norms, reinforcing trader consensus that the 42 °C-or-below bracket holds the dominant implied probability. Model guidance through the 18th continues to favor limited insolation and modest upper-level cooling, though any rapid clearing could still allow isolated pockets to reach 43 °C before resolution.
