In the next three days, rainfall in the north will expand eastward, and cooling will begin in the south.

China Weather Network News: In the next three days (September 7th to 9th), cold air will continue to affect the north, rainfall will expand eastward, and there will be heavy rain locally. The rainfall will also bring cooling. The cooling in the north is mainly concentrated from today to the 9th, and the south will also experience a wave of cooling from the 9th to the 10th.

In the next three days, rainfall in the north will expand eastward and rainfall in the south will weaken.

Starting yesterday, due to the influence of cold air, rainfall and cooling weather continued to occur in most areas of the north from west to east. At the same time, there is still rainfall in some areas in eastern Jiangnan and southern China. Monitoring shows that moderate to heavy rains occurred in parts of western Heilongjiang, western Jilin, eastern Inner Mongolia, central and eastern Gansu, eastern Qinghai, western Yunnan, central Guangdong, eastern Fujian, and northern Taiwan. Local heavy rains or heavy rains occurred in Xing'an League, Inner Mongolia, Pu'er, Yunnan, Yangjiang, Guangdong, and Shenzhen.

In the next three days, cold air will continue to affect the north, and heavy rainfall will expand eastward. The Central Meteorological Observatory predicts that today, there will be moderate to heavy rain in parts of eastern Qinghai, central and southern Gansu, central and northern Shaanxi, central and northern Shanxi, central and western Hebei, western and southern Beijing, western Sichuan Basin, northeastern Heilongjiang, southwestern Yunnan, southeastern Tibet and other places. Among them, there will be heavy rain in parts of central Shanxi and western Hebei.

Tomorrow, there will be moderate to heavy rain in parts of eastern and southern Qinghai, southern Gansu, central and southern Ningxia, central Shaanxi, central and southern Shanxi, southwestern Hebei, western Sichuan Basin, northwestern southern Xinjiang, and western Yunnan. Among them, there will be heavy rain in parts of central Shaanxi, southwestern Shanxi, and southern Gansu.

The day after tomorrow, there will be moderate to heavy rains in parts of northern and southern Qinghai, southern Gansu, central and southern Shaanxi, southern Shanxi, central and western Sichuan Basin, western Henan, and southeastern and western Yunnan. Among them, there will be heavy rain or heavy rain in parts of the western Sichuan Basin, southwestern Shaanxi, and northeastern Yunnan.

For Qinghai, Gansu, Ningxia and other places, this round of rainfall lasts for a long time, the cumulative rainfall is large, and the geological conditions in the above-mentioned areas are relatively fragile, so we need to be extra vigilant about local heavy rainfall that may cause flash floods, landslides, debris flows and other disasters.

Cooling begins from north to south, and temperatures in many places in the north will hit record lows in six months

In the next few days, the cold air will gradually move eastward and southward. In addition to bringing rainfall to the north, it will also bring a round of significant cooling from north to south. Among them, the cooling in the north is mainly concentrated from today to the 9th, and the south will also experience a wave of cooling from the 9th to the 10th.

The temperature in the north is relatively strong and accompanied by strong winds. The Central Meteorological Observatory predicts that from the 7th to the 9th, Inner Mongolia, the central and eastern parts of the northwest region, North China, Huanghuai, and Northeast China will experience a temperature drop of 4 to 6°C, with a local temperature drop of 8 to 10°C, accompanied by winds of magnitude 4 to 5 and gusts of magnitude 6 to 7.

Judging from the maximum temperature, the cumulative maximum temperature drop in most areas along the Yangtze River and north of it can reach 6°C to 12°C. Especially in southern Gansu, central and southern Shaanxi, Shanxi, southeastern Inner Mongolia, western Hebei, central and western Henan, northwest Hubei, and northeastern Sichuan, the drop can exceed 12°C, and the local drop can even reach about 20°C.

After the cooling, the temperature in various places will gradually drop to low levels, especially in some places in the north, which is more than 6℃ lower than the same period in normal years. The north will hit record low temperatures in the second half of this year in a large area. The maximum temperature in the eastern part of Northwest China, the western and northern parts of North China, and the central and western parts of Henan will drop below 20°C, and the lowest temperature will drop to about 10°C. The autumn coolness will be prominent, and the chill will become more severe in the morning and evening.

The heat in the south will be significantly relieved. The maximum temperature of 30℃ will gradually press southward to the eastern part of Jiangnan and northern South China, and the minimum temperature will mostly drop to around 20℃. Among big cities, Chongqing will continue to have hot weather in the next three days, but it will exit the high temperature ranks from the 10th, and the minimum temperature will drop from around 30°C to around 25°C, easing the feeling of heat.
