Current forecast models for Shanghai indicate overnight lows most likely in the 24–26°C range on July 3, driven by persistent subtropical monsoon flow, high humidity above 75%, and light southerly winds limiting radiative cooling. Ensemble guidance shows stable warm conditions following the end of the plum rain period, with historical July minimum averages near 25°C and limited variability from typical steering patterns. Recent model runs suggest modest cloud cover or scattered showers could cap any further warming, while uncertainty in exact timing of any frontal passage keeps probabilities spread across the mid-20s outcomes. Updated short-range forecasts and local observations over the next 48 hours will refine these market-implied odds ahead of resolution.
