Recent cold air advection across central China has driven a modest cooldown in Wuhan ahead of October 2, with northerly flow, persistent cloud cover, and scattered rain expected to limit daytime heating while promoting overnight radiative cooling. Official and ensemble forecasts indicate overnight lows clustered near 14–16 °C, though model spread in boundary-layer moisture and wind strength creates uncertainty around the precise minimum. Trader sentiment reflects this narrow range, with near-even implied probabilities for 13–15 °C outcomes capturing the limited but non-zero chance of either stronger cooling under clearer breaks or warmer advection if winds remain light. Resolution will hinge on the official 24-hour minimum recorded at the Wuhan meteorological station.
