Recent numerical weather prediction models from the China Meteorological Administration and international ensembles converge on a daily maximum of 28°C for Wuhan on May 17, driven by light southerly flow beneath a modest subtropical ridge that supports moderate daytime warming alongside partial cloud cover. This tight model agreement, consistent with mid-May climatological baselines for the region, underpins the market’s near-certain positioning for the 28°C outcome. Limited upside risk remains if unexpected clearing enhances solar insolation and pushes readings to 29–30°C, while any increase in cloudiness or frontal passage could cap the high below the target; the next official forecast update from the National Meteorological Center will provide the clearest near-term signal for traders.
