Recent short-range forecasts from global and regional models show Beijing's May 19 afternoon maximum likely reaching 25–27 °C, reflecting typical late-spring conditions with moderate southerly flow and limited cloud cover. Slight differences among outcomes hinge on model spread regarding peak solar heating, boundary-layer mixing, and any thin high-cloud layers that could trim temperatures by 1–2 °C. Historical May maxima average near 26 °C, providing a baseline traders weigh against the latest deterministic and ensemble runs. Updated guidance from the China Meteorological Administration and revised model outputs expected in the next 24–48 hours will likely narrow the tightest probabilities around the 26 °C and 27 °C thresholds.
