**Current short-range forecasts from multiple models indicate a nighttime low for Beijing on October 9 in the 11–15 °C range under mostly clear to partly cloudy skies, consistent with a stable high-pressure pattern and light southerly winds that limit mixing and allow moderate radiative cooling.** This places the most likely outcome near or slightly above the historical early-October average low of roughly 10–11 °C. The near-even market split between the ≤7 °C bucket (50 %) and the ≥17 °C bucket (49 %), with individual daily temperatures clustered around 34 %, reflects genuine model spread and the inherent uncertainty in precise minimum-temperature predictions only 48 hours out—small differences in cloud cover, boundary-layer winds, or the timing of any subtle frontal passage can shift the overnight low by several degrees. No major cold-air advection or significant precipitation is expected in the next 48 hours, keeping extremes less probable while leaving room for the final observed minimum (from official Beijing stations) to fall anywhere in the 10–16 °C envelope depending on the exact evolution of the GFS and ECMWF runs.
