BEIJING, Jan. 14 -- Beijing on Wednesday saw its first snow this winter while the city was enveloped by heavy smog.

Many Beijingers complained online that the scattered light snow was too small to be captured on camera.

The city's meteorological station recorded snowfall of less than 1 millimeter in the morning, with the snow likely to continue into the evening.

Beijing issued its first smog alert of the year on Tuesday. Stagnant and humid air has aggravated the city's air pollution, causing the smog to linger.

Yu Bo, chief weatherman with the Beijing Municipal Meteorological Station, said a cold front can be expected on Thursday evening to disperse the smog. This round of smog has affected much of north China.
