The local temperature may be record-breaking recently, but then the temperature will plummet.

Recently, the weather has cooled down and warmed up strongly, and the temperature has risen sharply, and the cooling is not to be outdone.
Cooling: The first cold air cooled significantly in Northeast China and other places.
Two cold air streams affected our country this week. Yesterday, a new cold air stream began to affect the north. Today and tomorrow, cold air will continue to move eastward, affecting many places in North China and Northeast China.
Today, cold air brings cooling to eastern Inner Mongolia and Northeast China.
The influence of this cold air is relatively northerly, mainly in western Inner Mongolia, north-central Northeast China, northern Xinjiang and other places, where the cooling range can reach 10 ~ 14℃ in northern Xinjiang and eastern Heilongjiang, and the local temperature exceeds 14℃.
For example, the cooling in Northeast China is very obvious. The highest temperature in Harbin was 4℃ yesterday, and it will drop sharply today and tomorrow. The highest temperature tomorrow is only -11℃, and the highest temperature in Changchun will drop to -2℃ tomorrow.
Temperature rise: the 20℃ line is lifted northward or warmed to a record.
Because the first stream of cold air has more than enough heart, it moves faster, and it doesn’t affect all places for a long time, mostly only about one day. After the impact, the temperature will rise rapidly. The south has not been affected by cold air, and the recent temperature has been all the way up.
Tomorrow and the day after tomorrow, the temperature in Inner Mongolia, Ningxia, Shaanxi, Shanxi, Hebei, Shandong, Henan, Hubei, Anhui and other places will be significantly higher than normal. The day after tomorrow, the maximum temperature of 20℃ will be rapidly pushed northward to the northern Henan-southern Hebei-northern Shandong line.
Taiyuan, Wuhan and Hefei may all approach or break the record of the highest temperature in December. For example, the highest temperature in Wuhan the day after tomorrow can reach 24℃.
Cooling: The second cold air "plummeted" in many places.
The temperature rise is so vigorous that the second cold air will also show its strength.
This weekend, due to the influence of cold air, the temperature in North China, Huanghuai and Northeast China will drop by 4 ~ 8℃, and the temperature drop in eastern Inner Mongolia and south-central Northeast China will reach more than 10℃.
Due to the obvious temperature rise tomorrow and the day after tomorrow, the temperature drop over the weekend will be very violent, and some places can even be described as "plunge".
Like Shijiazhuang, Jinan and Zhengzhou, the highest temperature exceeds 20℃ the day after tomorrow and will plummet to around 5℃ on Sunday. The highest temperature in Harbin and Changchun was above 0℃ the day after tomorrow, and plunged to less than -10℃ on Sunday.
At the same time, as the warm and humid airflow continues to strengthen northward and meet with cold air, there will be a large-scale rain and snow weather process in the central and eastern regions on October 10-11.
It is estimated that from October 10 to 11, there will be small to medium snow and local heavy snow in parts of North China and Northeast China, rain will turn to sleet or snow in northern Huanghuai and northwestern Shaanxi, and there will be small to moderate rain and local heavy rain in southern Huanghuai, Jianghan, Jianghuai, Jiangnan and northern South China.
Remind everyone that the temperature has fluctuated greatly recently, so everyone should pay attention to the weather changes and add clothes in time to avoid catching a cold.
