Lu Feiran/Shanghai Daily news

The official start of winter may be known today if forecasters are correct and the maximum temperature is just 9 degrees Celsius. That would mean a daily average below 10 degrees for five consecutive days and winter would have started last Sunday, the Shanghai Meteorological Bureau said yesterday. However, the city is expected to warm up from tomorrow and temperatures will again rise above 10 degrees, forecasters said.

Rain is forecast over the weekend as a weak cold front hits after today and tomorrow's sunshine. Temperatures will be between 6 and 12 degrees.
