Japan Meteorological Agency (JMA) forecasts drive trader consensus toward a Tokyo high of 23°C (44.5% implied probability) or 24°C (28.5%), reflecting clear skies and highs of 24-25°C expected on May 10 under a stable high-pressure ridge. Today's May 9 observations near 24°C amid sunny, breezy conditions with northwest winds support mild spring patterns, where average May highs hover around 23°C but recent model ensembles show slight spread due to potential afternoon cloudiness or station-specific measurements at Haneda Airport. Low precipitation odds (0-10%) favor warming via full insolation, though ensemble uncertainty keeps lower outcomes viable; monitor JMA's overnight updates for final guidance ahead of resolution.
