After entering the frost season, the temperature in the north will usher in a new round of cold air after a brief recovery.
China Weather Network News: After entering the frost period, the weather changes a bit quickly. Especially in the northern region, the warmth is just about to return, and new cold air is ready to strike. In the next few days, two waves of cold air from the east and one from the west will successively affect our country, and the temperatures in many places in the north and south will successively hit new lows in the second half of the year. China Weather Network has launched a cooling calendar for big cities to help you see the cooling nodes in various places in advance and arrange your clothing and travel.
The cold air ends the "intermission", and the cold air from the east and west will appear tonight
Starting yesterday, the last round of cold air ended, and the weather gradually began to warm up in the north. You can feel the long-lost warmth again when you go out in the afternoon. Today and tomorrow, temperatures will continue to rise in many places in the north, and the maximum temperature line of 20°C will move northward to southern Shanxi, northern Hebei, and central Beijing.
However, the warming is just a short "intermission" in the cold air, so don't be in a hurry to take off your thick coat. In the next few days, two waves of cold air will affect our country from east to west, from tonight to October 31st, and from October 31st to November 1st.
Among them, the cold air on the East Road affects the north, and will be the first to appear starting tonight. It is expected that from tonight to the 31st, the temperature in central and eastern Inner Mongolia, Northeast China, and northern North China will generally drop by 4°C to 8°C, with the drop reaching more than 10°C in some areas, accompanied by northerly winds of magnitude 4 to 6, and gusts of magnitude 7 to 9.
The cold air from the west will affect most of my country from northwest to southeast starting from October 31. This wave of cold air will have a wider impact than the first wave, and many places in the south will also be affected. The temperature in areas north of Nanling will generally drop by 4°C to 6°C, and the local drop can reach more than 8°C.
The temperature roller coaster is about to start. Temperatures in many places in the north and south may hit record lows in half a year.
Under the influence of two waves of cold air, from the end of this month to the beginning of next month, the highest temperatures in many places from the Northeast to the middle and lower reaches of the Yangtze River will set new lows in the second half of the year. It can be seen from the cooling calendar for large cities launched by China Weather Network that on October 31, the highest temperatures in Harbin, Changchun, Shenyang, and Beijing will all hit new lows. The highest temperature in Harbin on October 31 will drop to -1°C. This day may be the first time in the second half of the year that the temperature in Harbin runs below freezing point all day long. The cold will become significantly worse in many places in the Northeast. Not only autumn pants, but also cotton-padded clothes and thick coats should be prepared.
Compared to the north, cold air arrives later in the south, so it takes longer for the south to warm up. Around October 31, the temperature in the south will still be in the recovery stage. The highest temperature in many places in Jiangnan will exceed 25°C, and it can reach around 30°C in some places. However, after the arrival of cold air from the west, it is expected that around November 3, temperatures in many places in the south of the Yangtze River will hit new lows since the beginning of autumn. The highest temperatures in places such as Shanghai and Nanchang will fall below 20°C for the first time in the second half of this year. Among them, the highest temperature in Shanghai will still be 27°C on November 1st, and will drop to 21°C on the 2nd. Since then, the temperature has been falling, falling to 19°C on the 4th, setting new lows for three consecutive days.
However, it is already the end of the cold air reaching Nanling. Therefore, the high temperatures in South China will continue in the coming week, with the highest temperature still remaining around 30°C.
China Weather Network reminds that the temperature roller coaster is about to start. In the next few days, the temperature will change rapidly and fluctuate greatly in many places in the north and south. Please fasten your "safety belt". In addition to guarding against strong winds and cooling, the Northeast region also needs to pay attention to the adverse effects of rain and snow on transportation and facility agriculture. In the south, it gets warm first and then gets cold. The chill gets worse in the morning and evening, so you need to put on more clothes in time to prevent catching a cold.

The moderate typhoon fireworks continue to move northwest and west. Weather experts point out that due to the repeated strength and weakness of high pressure, there will be a tortuous trend of "westward → northward → westward → northward again" in the future. The probability of approaching Taiwan is very low, but a companion effect cannot be ruled out.
