Forecast for Thursday
PM2.5 pollution levels should be low on Thursday, generally from the Good range up to the low end of Moderate . This will give Beijing its fourth day in row of good air quality; unfortunately, this will be the last day of the streak as pollution levels increase overnight on Thursday into Friday morning. There is a small chance the increase will begin in the late evening Thursday, but this is unlikely. Most of us should first notice the increased pollution when we wake up on Friday.
