PM2.5 Forecast for Beijing - Wednesday, August 7, 2013

After an unexpectedly bad Tuesday evening, Wednesday has a good chance of continuing that trend.  Rising PM2.5 levels should keep us at Very Unhealthy at least through sunrise, but the weather forecasts diverge around 6AM.  One model shows the pollution increasing through late afternoon while the other shows some clearing beginning shortly after sunrise.  By early evening, the models converge again, so we should definitely see clearing skies through the evening.  So, look for pollution levels to trend toward one of the extremes from the graph; in either case, we should see Unhealthy or higher pollution levels through mid-afternoon at least.
