Trader consensus pins a 99.6% implied probability on Chongqing's highest temperature reaching exactly 21°C on March 22, propelled by converged numerical weather prediction models from the China Meteorological Administration forecasting mild spring conditions with daytime highs stabilizing there. Recent surface observations report morning lows around 15°C under partly cloudy skies and weak southerly winds, limiting convective heating while upper-air analyses show stable subsidence inhibiting warmer advection. Historical March baselines for Chongqing average 18-22°C maxima, reinforcing this outlook absent extremes. Challenges could arise from unexpected foehn-like downslope warming or rapid clearing boosting insolation, potentially nudging peaks to 22°C+, but current synoptic patterns render such shifts unlikely below 1%.
