ECMWF and GFS ensembles consistently project strong thermal advection into the Kanto region, with 850hPa temperatures exceeding +10°C. This synoptic setup, coupled with a robust high-pressure ridge, drives surface highs significantly above climatological normals. Market pricing currently undervalues the sustained mid-level warmth. Expect diurnal heating to easily push Tokyo past the 21°C threshold. 95% YES — invalid if Pacific anticyclone collapses.
