Rain Delay

I think the rain guage at DFW Airport is broken. Nearly 850 flights were either delayed or cancelled yesterday, yet the "official" rain guage said we only got around 2.5 inches of rain.

Really?

That small of an amount can delay planes?

Yes. I know. There was lightning involved. Yes. It was windy. But on the weather last night they were reporting totals of 5 or 6 inches at the airports all around DFW. And there are several airports all around DFW.

So, somebody's gotta be mistaken. Or maybe it's all that smog that causes the rain to bounce into the other airport rain guages.
