According to the prediction of the Beijing Meteorological Bureau, it is currently in early winter, and the middle and low-level temperature is near the critical point of the phase transition of rain and snow, and the phenomenon of rain and snow conversion may occur.
In addition, the daytime surface temperature in the urban area is expected to be above 0°C, and snowflakes may melt quickly after falling on the ground, and no obvious snow accumulation is expected.
