After the recent heavy rainfall in many places in the south of the Yangtze River and southern China, yesterday the southern region spent an extremely short period of weakening rainstorms, not only the scope and intensity of the rainstorm belt have been significantly reduced, but also there are almost no heavy rainstorms.
According to the latest weather forecast, from day to night today, the rainfall in the southern region began to turn from weak to strong again, and entered the most intense stage of this round of heavy rainfall, and Guangdong once again became the center of the heavy rain.
Among them, Guangdong, Guangxi, Fujian, Jiangxi, Hunan and other places have heavy to heavy rain weather, and there are heavy rain or extremely heavy rain weather in local areas in central and southern Guangdong, accompanied by short-term heavy rainfall, thunderstorms, strong winds or hail and other convective weather groups.

This time, the scope of heavy rainfall was more southerly than the previous round of heavy rainfall, and the rain also weakened, mainly in parts of eastern Guangdong and other places with heavy rain or heavy rainstorms.
There was moderate rain and locally heavy rain in parts of northwestern and south-central Guangxi, south-central Fujian, eastern Guangxi, and the Ili River Valley in Xinjiang.
The day after tomorrow, from 8 a.m. on April 27 to 8 a.m. on the 28th
With the gradual eastward movement of the southern branch trough, the role of cold and warm air masses and the subtropical high strengthened, the rainfall in the southern part of the Yangtze River and South China intensified again, and the convective weather began to increase rapidly, and the heavy rainfall belt expanded again.
There are moderate to heavy rains in north-central and eastern Guangdong, northeastern Guangxi, most of Fujian, southern Hubei, south-central Hunan, Jiangxi, etc., while there are heavy rains or heavy rainstorms in local areas in northern Guangdong, western Fujian, southern Hunan, and southern Jiangxi.
Immediately after the 28~30th, the high-altitude trough drove the low vortex to accelerate eastward, and there will be a round of heavy rainfall in most parts of the southern part of the Yangtze River, South China, Jianghan, Jianghuai, Sichuan Basin, Guizhou and other places, especially local heavy rain or heavy rain weather.
Around May 4 of the "May Day holiday", there will be moderate to heavy rain in most parts of Jianghan, Jianghuai, eastern and southern Jiangnan, most of South China, Chongqing, Guizhou and other places, and there will be heavy rain or heavy rain in some areas.
What will the temperature change and cold air conditions be like in the coming days?
As the cold air gradually dissipates, a strong dry and hot air mass head-on to the north, the temperature in most parts of the north will rise significantly, the highest temperature in Huanghuai, southern North China and other places will exceed 28 °C, and the local area has even reached 30 °C, and the temperature in eastern Heilongjiang and eastern Jilin in the northeast has rebounded by about 8 to 15 °C.
However, due to the influence of rainy weather in some parts of the south, the temperature in Guangdong, eastern Guangxi, central and northern Jiangnan and other places fluctuated, and the maximum fluctuation range of local temperature reached about 6 °C.
In this way, in the next few days, the temperature in Northeast China, North China, Huanghuai, western and southern South China, western Jiangnan, Shaanxi, eastern and southern Yunnan will be 1~3 °C higher than the same period in previous years, while the maximum temperature in western Sichuan, western Tibet, southern Xinjiang and other places will be about 3 °C lower, and the temperature in most other areas will continue to rise.
The May Day holiday is approaching, and many places in Jiangnan and South China will still be in the weather with more rain in the next few days, and local strong convective weather is frequent, especially Guangdong and other places will usher in a new round of heavy rainfall again.
While the spring rains continue in the southern region, the precipitation in central and southern Yunnan and southern Sichuan is very scarce, and the accumulated rainfall is still low.
