Forecast models from global and regional meteorological centers project maximum temperatures in Jinan reaching or exceeding 26°C on September 26, supported by warm southerly flow and stable high-pressure conditions typical of late September in Shandong province. Historical climatology shows average daily highs near 25–27°C during this period, aligning with current observational trends and ensemble consensus that keeps cooler outcomes below 5% implied probability. While model agreement is strong at this short range, an unexpected cold front or measurement revision at official stations could alter the outcome, though such shifts appear improbable given the latest guidance.
