"Wednesday's highest temperature is between 36 and 37 C, slightly lower than Tuesday, but the city won't see any rainfall until Friday and over the weekend," said Fu Yi, a chief service officer with the Shanghai Meteorological Bureau.
According to Fu, the scorching hot days would only be broken by intermittent thunderstorms starting on Friday. On Saturday, the mercury is expected to drop to about 32 C.
Shanghai expects to see about 22 to 27 high-temperature days — which are defined as having temperatures over 35 C — this summer. Only four days with temperatures higher than 35 C have been recorded thus far, including Wednesday.
The mercury hit 38 C on Tuesday in Shanghai, the highest daily temperature recorded so far in Shanghai this year. An orange alert, the second of the three-level color system, was issued that day. Yellow and red are the other color codes, with red being for temperatures that soar beyond 40 C.
