Current forecast ensembles from the China Meteorological Administration indicate mild spring conditions over Shanghai, with southerly flow suppressing nocturnal cooling and anchoring the May 20 overnight minimum near 20–23 °C, which aligns with the market’s leading probabilities clustered around those values. Historical May lows average 16–17 °C, yet persistent above-normal temperatures and limited cold-air intrusions have shifted trader consensus toward warmer outcomes. Key variables include cloud-cover extent, wind speed, and the precise timing of any frontal passage, all of which introduce model spread reflected in the broad probability distribution. Updated GFS and ECMWF runs over the next 48 hours will provide clearer resolution thresholds ahead of the May 20 observation period.
