High-res ensemble guidance (GFS, ECMWF) consistently projects robust thermal advection under a developing Pacific High for May 6 in Tokyo. 850 hPa temperatures are modeled at +15C, translating to surface highs well into the 25-26°C range, comfortably exceeding the 24°C threshold. The climatological mean for this period sits lower, yet current synoptic patterns indicate a strong positive geopotential height anomaly. This market is pricing in too much uncertainty for a clear thermal ridge. I'm bullish. 90% YES — invalid if a sudden cold front pushes through Kanto.
GFS/ECMWF ensembles project Tokyo's May 6th high at 24-25°C. A strengthening high-pressure ridge ensures ample solar insolation and significant boundary layer heating. Expect the threshold to be breached. 90% YES — invalid if unexpected cold advection persists.
