Following last night's drama, August is set to play out with gray, wet days, though with thundershowers, forecasters said yesterday.

Frequent showers with the possibility of thunder and lightning are forecast for today, under the combined influence of warm and cold air masses, said the Shanghai Meteorological Bureau.

Cooling rains

While yesterday the mercury reached 34 degrees Celsius, before it clouded over and the thunder and lightning arrived in the evening, today's high will be around 30 degrees, due to cooling from overnight rains.

Tomorrow should be dry, though without much change in temperatures.

On Wednesday, thunderstorms will return and cool the city to between 24 and 28 degrees with rain forecast the whole day.

Thursday will see a pause in the rain, but showers are forecast on Friday afternoon is some areas.

Temperatures for Thursday and Friday will range between 23 and 30 degrees.

Due to a north-moving subtropical high, the weekend should be overcast, said the bureau.

Early blossom

Wu Zhixing, a local expert specialized in gardening, said sweet osmanthus is coming into flower during this year -- the earliest for 35 years. “It's rare for sweet osmanthus to flower just after the solar term chushu, or the end of dog days sanfu,” Wu said.

"Sweet osmanthus usually flowers between late September and early October."

According to Wu, the sweet osmanthus blossom requires the temperature to be around 25 degrees and with enough humidity.

The local weather bureau's five-day forecast shows the temperatures of the weekdays will fluctuate between 23 and 30 degrees, suitable for sweet osmanthus to flower.

As long as no freak temperatures or torrential rains occur in the next few days, sweet osmanthus will soon be seen flowering in abundance, said Wu.
