PM2.5 Forecast for Beijing - Saturday, April 13, 2013

After better than expected air on Friday (peaking at 159, at the low end of the Unhealthy range), we should see poor air quality in the morning, likely Unhealthy      but possibly at the low end of Very Unhealthy     .  But a wind shift should clear out the pollution between mid-morning and early afternoon, putting the air quality back into the Moderate      or Good      categories by late afternoon.
