Numerical weather prediction models from the European Centre for Medium-Range Weather Forecasts and GFS ensembles currently converge on a 25–27 °C daily maximum for Wuhan on May 18, with the highest implied probability on 26 °C. This range reflects the arrival of increased cloud cover and scattered thunderstorms that will limit daytime solar heating over the Jianghan Plain. Mid-May climatology for the region shows average highs of 26–28 °C, so the current forecast sits near normal yet carries modest uncertainty from the exact timing and intensity of precipitation. Any delay in storm development or clearer morning skies could push readings toward 27–28 °C, while earlier or heavier rain would favor the lower end near 25 °C. Final high-resolution model updates and China Meteorological Administration observations in the next 48 hours will sharpen the resolution criteria before market close.
