CCTV.com News: According to China Weather.com, the weekend that just ended was full of "hot" force, and the warmth in many places has reached an almost crazy level!

During the day (March 23), the highest temperatures in many places including Changchun, Chenyang, Xi'an, Lanzhou, Yinchuan, Chongqing, Chengdu, etc. have hit new highs this year. Among them, Changchun's 20.7℃ exceeded 20℃ for the first time this year; Shenyang's 26.1℃ reached above 25℃ for the first time this year, and broke the local high temperature record in March.

It is expected that the highest temperature in many places in the north will continue to rise in the next two days. For example, Lanzhou, Taiyuan, Xi'an, Xining and Zhengzhou, the highest temperatures will hit new highs this year in the next two days. Among them, the highest temperature in Zhengzhou on the 25th could reach 33℃, which will break the local high temperature record in March. Moreover, this popularity is not only in May and June levels all year round, but even equivalent to early July all year round.

The time when the temperature in the south hits a new high will lag a little later. It is expected that from the 25th to the 26th, the highest temperatures in Hefei, Wuhan, Nanjing, Shanghai, Hangzhou, Changsha, Nanchang, Chongqing, Guiyang, Chengdu and other places will hit new highs this year. Moreover, the highest temperatures in Changsha and Nanchang on the 26th may reach 33℃. If fulfilled, they will break the local high temperature record in March.

However, in this big recovery, the rebound of the lowest temperature has always been "stopped", and the temperature difference between day and night continues to widen. It is expected that the temperature difference between day and night in most parts of my country will be above 10℃ or 15℃, and the temperature difference between day and night in some parts of the north will exceed 20℃. Such a large span temperature difference tests everyone's dressing level, but as long as you master the "onion dressing method", you will not be afraid even if you go out early and come back late.

The temperature rises too fast, and it even becomes a little "floating". Don't worry! Cold wave will take action!

The Central Meteorological Observatory predicts that from March 25 to 29, except for the Qinghai-Tibet Plateau, the temperature in most areas of the country will drop by 8 to 12℃, and the cooling range in the eastern part of the northwest region, western North China, southern Huanghuai, Jianghuai, Jiangnan and other places can reach 14 to 16℃, and the daily maximum temperature drop in some areas will exceed 20℃. After the cooling, the minimum temperature 0℃ line on the morning of the 30th will be located in the area between central North China and southern Shaanxi; the daily maximum temperature in North China is 10-15℃.

In cities, the cooler temperature is like Zhengzhou, with the highest temperature dropping from 33℃ to 13℃; Wuhan, 32℃ to 11℃; Nanjing, 34℃ to 14℃. The cooling rate in the above cities is 20℃ or above, which is another roller coaster experience with ups and downs! Therefore, in the first half of next week, you may need a cotton jacket to protect your body.

In terms of precipitation, we should pay special attention to the intersection of cold air after moving eastward and southward, and will stimulate a large range of precipitation south of the Huaihe River from the 26th to the 28th.

The Central Meteorological Observatory predicts that from the 26th to the 28th, there will be light to moderate rain or thunderstorms in the areas south of the Huaihe River, and heavy rain in some areas; the above-mentioned local areas will be accompanied by strong convective weather such as short-term heavy rainfall, thunderstorms and strong winds.

And due to the high basal temperature and the unstable atmosphere and sufficient energy, rainfall in some areas may also be accompanied by strong convective weather. The forecast is currently relatively long, so I remind you to continue to pay attention to the approaching weather forecast.
