While the autumn rain cools down the temperature, there is still warmth and heat on the other side. The north and south are experiencing the coexistence of winter and summer.

Today, cold air appears in the north, and the northwest region is the first to be affected, with autumn rain and cooling coming online at the same time.

Tomorrow, the scope of rainfall and cooling will extend to North China and Huanghuai. The maximum temperature in many places in central and eastern Inner Mongolia will drop by 6°C to 12°C in a single day. Some areas in southern Shanxi, southern Hebei, and northern Shandong will experience significant rainfall. The day after tomorrow, the focus of cooling will shift to the northeastern region, with the maximum temperature drop in most places reaching 6°C to 10°C. Most of the rainfall will be light rain or showers.

This cold air will have a limited cooling effect on most of the north, but the northeastern region and central and eastern Inner Mongolia will cool down drastically. Temperatures in many places will temporarily drop to lower than normal levels, and set new lows in the second half of the year. For example, in Harbin, the maximum temperature tomorrow will be 23℃, which will drop to 10℃ on the 14th, setting a new low in the past six months. The minimum temperature may also be the first time since the beginning of autumn to fall below the freezing point.

This cold air has little impact on temperatures in the south. Controlled by the strong subtropical high pressure, the south will continue to be warm in mid-October. The maximum temperature in many places in Jiangnan and South China will reach around 30°C, and in southern China it will exceed 33°C. Local high temperatures will appear, and the warmth will still be strong... According to the Central Meteorological Observatory’s mid-term forecast, in the next 10 days, the temperature in Huanghuai, Jianghan, Jianghuai, Jiangnan, South China, Sichuan Basin and Guizhou will be 2°C to 5°C higher than the same period in normal years.

However, due to the arrival of this cold air, the temperature difference between the north and the south will further widen in the next few days, creating a scene of "winter and summer coexisting". And in the later period, as the cold air penetrates southward, southwest, Jiangnan and other places will usher in a new round of rainfall.

This round of large-scale rainfall will first develop in the southwest, and the precipitation area will expand eastward to the Yangtze River Basin on the 14th. On the 15th, the subtropical high pressure will withdraw southward, and the warm and humid air flow will strengthen. The rainfall will further intensify in many places in the Yangtze River Basin. There may be heavy rains in northern Hunan, eastern Hubei, southwestern Anhui and other places. Continue to pay attention.

In addition, in addition to super typhoon "Little Bear", there are also tropical disturbances 95W and 96W at sea. Among them, 96W has great potential for future development, so continue to pay attention. Finally, you can use a picture to understand the weather trend next week. You can see whether your place will be sunny and hot, rainy and cool, or heavy rainfall will spread.
