Starting from tomorrow, my country will gradually cool down from north to south, and many areas will experience widespread rain and snow.

China Weather Network News The warming balance is insufficient! Recently, most areas across the country have experienced a wave of warming. However, from tomorrow (November 14th) to the 18th, the cold air will exert force again, and the temperature will drop off a cliff in many places in the north and south. The freezing line will press all the way south to the Huaihe River Basin, and the coldness will return. At the same time, large-scale rain and snow came online, and local snowfall was severe in the Northeast. The China Weather Network has launched a map of the national cooling process to see when various regions will usher in a reversal of cooling.

This week has entered a period of intermittent cold air, with temperatures steadily rising in most parts of my country. The maximum temperature line of 10℃ has moved northward to the southeastern Heilongjiang area, and the 20℃ line has moved northward to the middle and lower reaches of the Yangtze River. Among them, the northeastern region is the most prominently warmer than the same period of the year. The highest temperature in Shenyang yesterday reached 16°C, which was full of warmth and felt comparable to mid-October.

However, after a brief recovery, the north and south will usher in a major cooling. Sun Qianqian, a meteorological analyst at China Weather Network, said that from the 14th to the 18th, two waves of cold air will relay southward. The two waves of cold air are not very strong, but the early warm pattern has reserved space for cooling, and the cumulative cooling rate will be relatively large. After the cooling, temperatures in the north and south will hit record lows in half a year in large areas. In the early morning of the 19th, the minimum temperature line of 0°C will press southward to the Huaihe River Basin, which is further south than the previous cold wave.

Judging from the national cooling process map launched by China Weather Network, the cooling will gradually spread from north to south. On the 14th, the northwest, northeast, and northern North China were the first to experience cooling. On the 15th, the cooling range further expanded, covering most of the north, with local cooling reaching 12°C or above. After this round of cooling, most areas in the north will turn from warm to cold. For example, in Shenyang, the maximum temperature will drop from over 16°C to 3°C, and Lanzhou and Jinan will drop from close to 20°C to single digits.

The cooling time in the south lags behind that in the north, and the temperature will continue to rise before the cold air arrives. From the 16th to the 17th, as the main body of cold air arrives, the south will gradually join the ranks of cooling, and the temperature drop in some cities can exceed 8°C; on the 18th, the cold air will cross the Wumeng Mountain and Nanling, and the cooling area will reach South China and Yunnan. In cities, the highest temperature in Wuhan was 21°C on the 15th and dropped to 11°C on the 19th. In Changsha, the highest temperature was 22°C on the 15th and dropped to 13°C on the 19th. The contrast between cold and warm before and after was obvious.

As the cold air moves southward and the warm and humid airflow moves northward, my country will experience widespread rain and snow. It is expected that snowfall or rain will turn to snow from the 15th to the 17th in the central and eastern parts of Northwest China, northern and western North China, Northeast China, and western Huanghuai. According to Sun Qianqian's analysis, the overall intensity of this round of snowfall in North China is not as good as that of the previous cold wave, but the intensity of snowfall in the eastern part of Northeast China will be significantly upgraded, with blizzards, severe blizzards, and even severe blizzards in some areas. The current time limit is still far away, so we need to pay attention.

China Weather Network reminds that cold air activities tend to become more frequent in mid-November, and the temperature fluctuates greatly in most areas of my country. The public is advised to adjust clothing appropriately according to temperature changes and beware of colds. There will be heavy snowfall in the Northeast next week, which is prone to snow, ice and reduced visibility on roads, which may have an adverse impact on traffic. The public is asked to take precautions in advance.
