China Weather Network predicts that the north is dominated by snow, the main impact period is from tonight to January 23, and the south is mainly rainy, and the main impact period is from 21 to 23, covering more than 25 provinces, autonomous regions and cities.
Specifically, the strong southwestern air current carries sufficient water vapor deep into the northern part of the continent, providing favorable conditions for precipitation. The cold air in the north is active, but it is not enough to repel the warmth and humidity in a big way. Cold and warm chase each other, and precipitation will take turns.
In the coming week, the central and eastern parts of the mainland will usher in two large-scale rain and snow processes in succession, with a wide range of influence and a long precipitation time.

This weekend in Shanghai was dominated by rain. Among them, on Saturday (January 22), due to the intensification of the intersection of cold and heating currents, the precipitation is more obvious, and everyone is prepared for rain and pays attention to traffic safety. In the short term, rain is still dominated by warm and humid airflow, it will not be particularly wet and cold, and the maximum temperature on weekends is still 11 °C.

From January 24 to 25, cold air will press the rain area south, and there will be a short rain break, but the sun is still a rare thing, and it is necessary to take the opportunity to wash and dry clothes.
On January 26, a new round of precipitation struck. The Shanghai Meteorological Department said that the rain and snow area moved east to the south, and it is necessary to pay close attention to the evolution of the situation in the later stage.
