Spring-like weather chasing away chill

EXPECT several days of beautiful, spring-like weather early this week with partly sunny skies, forecasters said.

Highs are forecast to remain at about 14 degrees Celsius today and tomorrow, with the low between 4 and 5 degrees on those days.

Moderate pollution was recorded this morning with concentrations of the main pollutant, tiny PM2.5 particles, hitting 157.7 micrograms per cubic meter at 11am, just over double the nation's limit of 75. The pollutants are likely to drop in the afternoon and bring back a good air quality.

While double-digit highs are forecast all week, the weather will vary starting midweek.

A weak colder air mass from the north is forecast to start moving in on Wednesday and bring some rain, though the high is forecast to rise to 15 and the low to 9 degrees Celsius.

A dip in temperatures will be seen on Thursday as the cold air expands, with the high forecast to be 11 and the low 6 degrees Celsius.

Friday's high will return to 14 degrees and the low to 4 degrees.

North China is now affected by heavy smog and poor air conditions, which will be relieved by the cold front there on Tuesday, according to the National Meteorological Center.

But the Shanghai weather bureau said it's still unsure whether the cold air will bring particles to the city and cause smog here.

"The formation of smog is more likely under the combined action of a great number of particles in the air and some specific weather conditions such as stable, dry weather," Zhang Ruiyi, a chief service officer at the bureau, told Shanghai Daily.

"If some weather changes like increasing winds or rainfall occur, the smog will be less likely to form or hang out for a long period.”
