PM2.5 Forecast for Beijing - Friday, November 8, 2013
We're back to solidly poor air quality for Friday in Beijing. PM2.5 levels have been rising since late afternoon on Thursday, and that trend should continue overnight, possibly bringing us up to Hazardous conditions. Around sunrise, the weather forecasts we have diverge, so our prediction range is quite wide for most of the day. Friday's "high" scenario has levels increasing until about noon, leveling off for a bit, then picking back up as it moves over 400 AQI. But Friday's more positive "low" scenario has levels peaking at the high end of Unhealthy around sunrise, dropping slightly through the late morning/early afternoon, then slowly rising again. We'll hope for the best.
