Robust GFS and ECMWF ensembles, particularly the 00z runs, indicate dominant high-pressure ridging over Central China by May 5. This synoptic pattern will drive significant thermal advection from the south, coupled with strong diurnal heating under clear skies. Current model outputs consistently project Wuhan exceeding 30°C, with some reaching 31-32°C, well above early May climatological norms. This is a high-confidence hot advection event. 95% YES — invalid if a transient cold front prematurely disrupts the ridge.
