With the cooperation of the strong warm and humid airflow, the large-scale rain and snow in the north "arrived" one after another. On the 11th, this round of rain and snow is the most prosperous period, and many will usher in the first snow this winter. .

　　According to Hu Xiao, chief meteorological analyst at China Weather Network, starting from the night of the 10th, the precipitation in Shaanxi, Shanxi and other places will increase first, and then rapidly expand eastward.

During the daytime on the 11th, there will be rainfall in central Inner Mongolia, Hebei, Beijing, Tianjin, Henan and other places one after another.

The middle and lower reaches of the Yangtze River can feel the "seasonal" cooling

　　In the next few days, this cold air will move eastward and southward, and the cooling effect will reach the south of the Yangtze River.

　　According to Shi Yan, a meteorological analyst at China Weather Network, the cold air has mainly affected Northwest China and Inner Mongolia and other places in the past two days.

The cooling range was the largest on the 12th, with a temperature of 6-10°C in most of the Northeast, eastern North China, Jianghan, and western Jianghuai, and 10-15°C locally.

On the 13th, the eastern part of the southwest region and the Jiangnan area will also join the ranks of cooling.

　　During this cooling process, the Northeast and the Yangtze River Basin had the most significant cooling.

Due to the obvious warming in the early stage, the cumulative drop of the maximum temperature in many places will exceed 10 ℃, and some areas will reach more than 15 ℃.

The highest temperature in the Northeast will drop from above 10°C to nearly 0°C, and the middle and lower reaches of the Yangtze River will drop from about 30°C to about 15°C.

　　Among the big cities, Wuhan, Hefei, Hangzhou, Changsha, and Nanchang will have the highest temperature drop of 15℃ or more. For example, in Changsha, the highest temperature will be around 31℃ today and tomorrow, and it may drop to only 12℃ on the 14th. And accompanied by rainy weather, the body feels relatively wet and cool.

　　Shi Yan reminded that this cold air belongs to the "correction type" cold air. After cooling down, the temperature in various places mostly returns to normal or slightly lower levels in the same period of the year.

However, in some areas such as Jiangnan, the temperature was obviously high before cooling down. During the cooling process, the body feels like crossing from early summer to late autumn. The contrast between hot and cold is very obvious.
