It is difficult to stop the ＂oven＂ mode in North China. The local temperature is 40℃, and it rains frequently in South China.

　　CCTV News:According to the website of China Weather Network, it is predicted that there will be moderate to heavy rain in Jiangnan and South China tomorrow (3-4), and the high temperature will be basically eliminated; At the same time, the north is still unable to escape the high temperature. Today, the heat in North China is slightly reduced, but from tomorrow, the high temperature weather will increase and expand to Huanghuai, and the local temperature will even hit 40 C.

　　Northeast bid farewell to high temperature, North China high temperature rises again.

　　Affected by the ridge of high pressure, the temperature in the northeast has been hot in recent days. Harbin ushered in the first high temperature this year, which is rare in history, while Xing ‘an League in Inner Mongolia and parts of southwest Heilongjiang challenged the high temperature of 40℃, which was unbearable.

　　However, with the arrival of cold air, today, the northeast will be completely freed from the high temperature roasting. It is expected that there will be obvious temperature drop in the central and eastern Inner Mongolia, the western part of Northeast China and other places, with the drop generally reaching 8-12℃ and the local temperature above 15℃. Under the influence of cold vortex, this coolness will also run through next week.

　　For North China, which is also scorched by high temperature, it is not so easy to get rid of the high temperature with the help of cold air. Although the highest temperature today has been suppressed to below 35℃, the high temperature will "re-ignite" and gradually increase from tomorrow, and then it will sweep the Huanghuai area. It is estimated that there will be high temperature of 35-38℃ and local temperature of 40℃ in North China and northern Huanghuai on May 7.

　　Meteorologists reminded that looking forward to the coming week, high temperature will be the dominant weather stage in the North China Plain and its surrounding areas. Affected by the high temperature weather in partly cloudy, the solar radiation is strong during the day, and there will be ozone pollution from noon to afternoon, so sensitive people should try their best to reduce going out; This hot weather will continue into the college entrance examination, and candidates should prepare for the hot weather during the examination in advance.

　　Rainwater in South China frequently causes local or heavy rain.

　　The past May should be a painful memory for South China, where the frequent rainfall was replaced by the unusually hot and muggy weather. However, from June 1st, with the rainfall gradually becoming the leading role, the high temperature gradually declined. Monitoring shows that there were heavy rains in central and western Guangdong, central and southern Guangxi, eastern Yunnan and southwestern Fujian yesterday, and heavy rains (120-210 mm) in Baise, Yulin and Wenshan, Yunnan, and the maximum hourly precipitation in these areas was 50-97 mm.

　　During the day today, the rain in South China will rest temporarily, but from today night to the 5th, there will be a precipitation weather process from west to east in the eastern part of southwest China, south of the Yangtze River and South China, with moderate to heavy rainfall, local heavy rain or heavy rain.

　　In addition, during the day to night on the 3rd, there were scattered heavy rains or rainstorms in parts of South China, southern Guizhou, Yunnan and other places, accompanied by strong convective weather such as short-term heavy precipitation and local thunderstorms and strong winds.

　　The Central Meteorological Observatory predicts that there will be small to moderate rain in most parts of southwest China, south-central Jiangnan and most parts of southern China today, and there will be heavy rain or rainstorm (100-120 mm) in the eastern and southern parts of southwest China and northern and central South China. These local areas will be accompanied by strong convective weather such as short-term heavy precipitation.

　　Tomorrow, the rain will continue to push eastward. It is expected that there will be moderate to heavy rain and local heavy rain in most parts of Yunnan, southeastern Guizhou, northwestern Guangxi, most parts of the south of the Yangtze River, southern coastal areas of Guangdong, Hainan and other places, and these local areas will be accompanied by strong convective weather such as short-term heavy precipitation.

　　In addition, the tropical disturbance in the South China Sea was intensified into a tropical depression yesterday, and it is expected to develop into the fourth typhoon (tropical storm level) this year from day to night, and gradually approach the eastern coast of Hainan Island.

　　It may affect Hainan and Guangdong before and after the college entrance examination. There may be some uncertainties about the time and place of typhoon landing, so we need to continue to pay attention.

　　Affected by this, from the 3rd to the 5th, there will be 7-9 winds and 10-11 gusts in most parts of the South China Sea, Beibu Gulf and Qiongzhou Strait. From the night of the 4th, there will be heavy rain in Hainan Island and the southern coast of South China, and there will be heavy rain locally.

　　Meteorologists reminded that this round of precipitation process may be accompanied by strong convective weather such as short-term heavy precipitation, thunderstorms and strong winds. It is necessary to pay attention to the forecast and strengthen prevention. At the same time, precipitation may cause slippery roads and accumulated water on the road, so you need to pay more attention when traveling.
