Current ensemble forecasts from the Japan Meteorological Agency and global models show considerable spread for Tokyo's overnight low on May 25, with projected values clustering near 17–18 °C amid a warm late-spring pattern. Above-average May temperatures driven by a strengthened subtropical high have kept recent nights mild, yet a possible weak frontal boundary or increased cloud cover could shave several degrees or allow clearer skies to hold values higher. Historical climatology places typical May minima around 15–17 °C, providing a baseline against which traders weigh short-range model runs and observed trends from the preceding 48 hours. Resolution hinges on the exact 24-hour minimum recorded at the official Tokyo station.
