41 degrees and partly smoky

Beijing weather is pretty bad. During the summer, sandstorms blow in from the West. During the winter, the air is so dry every cubicle in corporate offices will have a rising column of steam coming out of a humidifier. However, last week, it was "smoky" in Beijing, at least according to my Accuweather forecast. When I looked out the window, I didn't notice any substantial difference from the typical "partly cloudy" or "foggy" descriptions.
