The strongest period of this round of precipitation has arrived, with heavy rains hitting a large area in the north
As the subtropical high pressure strengthens, a large amount of water vapor is transported to my country along its edge. After meeting the cold air, the scope of precipitation in my country expanded yesterday. Live monitoring shows that heavy rains occurred in parts of northern Ningxia, central and southwestern Shaanxi, southern Shanxi, central and southeastern Henan, northern Chongqing, central and western Hubei, and southeastern Yunnan. Local heavy rains or heavy rains occurred in Wuxi, Chongqing, and Honghe, Yunnan. Light to moderate snow or sleet occurred in parts of northern Xinjiang, central and western Gansu, eastern Qinghai, and northern Sichuan Plateau.

The Central Meteorological Observatory predicts that there will be heavy to heavy rains in parts of central and eastern Inner Mongolia, southwestern Heilongjiang, western Jilin, most of Liaoning, central and northern Hebei, Beijing, Tianjin, northeastern Shanxi, central and southern Shandong, eastern and southern Henan, northern Anhui, northern Jiangsu, central and southern Hubei, northern Hunan, and northern Chongqing. Among them, there will be local heavy rains in southwestern Shandong and southern Liaoning. Moderate to heavy snow or sleet occurred in parts of northern Xinjiang, central and western Gansu, central and eastern Qinghai and southern Qinghai, northeastern Inner Mongolia, northwest Heilongjiang, and eastern Tibet. Among them, there were local heavy snowfalls in northeastern Inner Mongolia and northwest Heilongjiang.
Tomorrow, the rainfall will end in most parts of North China and the Huanghuai River, but there will still be significant rainfall in the Northeast and along the middle and lower reaches of the Yangtze River. It is expected that there will be moderate to heavy rains in parts of central and eastern Heilongjiang, eastern Jilin, eastern Liaoning, southwestern and eastern Hubei, northwestern Hunan, central and southern Anhui, central and southern Jiangsu, Chongqing, and northern Guizhou. Among them, there will be heavy rains in northeastern Jilin, central Anhui, central and southern Jiangsu, eastern and southwestern Hubei and other places. Some areas in northeastern Inner Mongolia and northwest Heilongjiang experienced moderate to heavy snow or sleet, and local heavy snowstorms.
The day after tomorrow, there will be moderate to heavy rains in parts of southern Henan, southwestern and northeastern Hubei, central and northern Anhui, central and northern Jiangsu, and eastern Chongqing. Among them, there will be heavy rains in central Jiangsu, southwestern Hubei and other places. There will be light to moderate snow or sleet in some areas in northern and southern Qinghai, Hexi in Gansu, central and northeastern Inner Mongolia, northwest Heilongjiang, and northern North China.
China Weather Network reminds that this round of precipitation in the north may be rare in terms of scope of influence, cumulative precipitation, and single-day precipitation intensity during the same period. The snowfall intensity in northeastern Inner Mongolia and northwest Heilongjiang is heavy and lasts a long time. The public needs to guard against the adverse effects of rain and snow on transportation, agriculture, etc., and also needs to be alert to secondary disasters that may be caused by heavy rainfall.
Temperatures in the north will frequently reach new lows, and Jiangnan and other places will experience cooling next week
In the three days starting today, the stronger cold air will continue to move eastward and southward, bringing cooling to most areas in the middle and lower reaches of the Yangtze River and its north. After that, there will be two waves of cold air that will affect our country from the 20th to the 21st and from the 23rd to the 25th.
Under the influence of cold air, in the next five days, temperatures in the north will frequently reach new lows in the second half of this year. Among them, the highest temperatures in Beijing, Taiyuan, Tianjin, Shijiazhuang, Lanzhou, Yinchuan, Jinan and other places will set off a wave of record lows today. Then the temperatures will fluctuate, and will continue to drop and hit new lows in a wide range around the 21st.
Judging from the minimum temperature, around the 21st, the 0℃ line will advance southward to central Shaanxi and southern Shanxi, and the minimum temperatures in Xining, Taiyuan, Yinchuan and other places will successively drop to freezing point or below. The minimum temperature line of 10℃ will also press southward to Huanghuai, and the minimum temperature in Beijing and Shijiazhuang will continue to be lower than 10℃ starting the day after tomorrow.
Under the control of the subtropical high pressure in the south, the range above 30℃ today is the widest in recent times, with the northern boundary extending to Hubei and southern Anhui. The pattern of relatively high temperatures will continue into next week. On the 21st, Jiangnan and other places will also experience a temperature drop of more than 10°C. The maximum temperature in Shanghai, Hangzhou, Changsha and other places may drop to around 20°C, marking the onset of cool autumn weather. The public should pay attention to temperature changes and add clothing when appropriate.
