For the last few days it's been hot and humid here, which is unusual for Beijing, known for its hot dry summers.
But everyday it's been muggy and hazy. And yesterday was so hot that I thought it would surely rain last night.
However, the temperature cooled just enough to prevent any precipitation from forming.
A visiting friend thought she needed to get her eyes checked because she couldn't see clearly outside. "It's not you," I replied. "It's the pollution."
This morning China Radio International said the forecast was "foggy" with heavy rain in the afternoon.
While it might have looked foggy, the city was covered in a deep haze rather than mist.
And finally late this afternoon the sky grew dark and rumbling thunder and flashes of light flew across the sky signaling rain. And it rained hard for a few minutes.
It's evening and there's still intermittent lightning, thunder and rain.
I hope it continues all night so that tomorrow morning the sky will be so clear my friend will wonder if her eyes are too sharp.
