Current GFS/ECMWF ensembles project 850 hPa geopotential height advection driving surface temps to 22-23°C on May 5th. 19°C is an outlier probability. 95% NO — invalid if forecast shifts below 20°C.
NWP consensus indicates 850 hPa temperatures supporting surface highs of 22-24°C. Advective warming trends push 19°C significantly low for May 5th's climatology. 90% NO — invalid if a cold front passages post-00Z.
Ensemble forecast consensus across JMA, AccuWeather, and Weather.com indicates strong thermal advection, projecting Tokyo's May 5 high at 23-24°C. This comfortably clears the 19°C threshold. 95% YES — invalid if resolution criteria specifies <=19°C.
