Under the control of the subtropical high, the high-temperature and hot weather from Chongqing to Jiangnan will not stop in the next few days. The highest temperature in Chongqing and other places will exceed 40 ℃, and the heat wave will roll. The places on the north side of the subtropical high have frequent precipitation. Today (August 12), there were moderate to heavy rain in some areas such as southern Hebei and North Central Shandong, and heavy rain in northern Shandong. The high temperature and extreme heat never stop in Chongqing, Wuhan and other cities or encounter local rare heat waves.

Yesterday, Chongqing, Shanghai, Zhejiang and other places were still hot waves, and the temperature of Shanghai Xujiahui Station once again rose above 40 ℃. This is the sixth local extreme hot weather exceeding 40 ℃ this year, It also set a new record for the extreme hot days above 40 ℃ since the complete observation of the station in 1873 (the previous record was 5 days in 2017); The temperature in Hangzhou reached 40.9 ℃, setting a new high in this year. In the next few days, the high-temperature and hot weather in the above-mentioned areas will not stop. The high-temperature intensity and duration from Chongqing to the south of the Yangtze River are large, and rare high-temperature and hot weather may occur in many places. Moreover, the high-temperature range will expand northward for a short time. The Southern Hebei and Huanghuai will return to the high-temperature ranks for the time being. Among them, today, there are 35-39 ℃ high temperature weather in the eastern part of Xinjiang Nanjiang basin, western Inner Mongolia, central and southern Shaanxi, Henan, Anhui, Jiangsu, Shanghai, central and Eastern Sichuan, Chongqing, Hubei, Hunan, Jiangxi, Zhejiang, Fujian and Northern Guizhou.
