I was checking out the weather in Charlotte via Google's Weather Underground Full Page Weather extension and I noticed the area was under a thunderstorm warning. While reading it, I saw this:
... Airport weather warning for a severe thunderstorm threat a cloud
to ground lightning threat at the Charlotte Douglas international
Airport...
The National Weather Service in Greenville-Spartanburg has issued an
Airport weather warning for...
Charlotte Douglas international Airport /clt/
* valid until 515 PM EDT
For the following threats...
* Severe Thunderstorm Warning for winds of 58 mph or greater and hail
1 inch in diameter or larger.
* Cloud to ground lightning within 5 miles of the Airport.
Haven't seen anything like that from the NWS. Have you all have?

Nope, that's new to me. :blink:

I don't know how "new" these are (if at all), but I remember seeing a lot of these warnings back in May when we had our severe thunderstorms.

It's been around since 2001, but I think only some offices participate in using it. The Airport Weather Warning is issued for airports only when there will be surface winds of 40 knots (46 mph) or higher, onset of freezing rain, cloud-to-ground lightning within 5 miles and approaching the airport, thunderstorm with 1/2" hail or larger, or the onset of heavy snow. In short, it's for anything really hazardous to aviation. I found a NWS letter online where it states the introduction of this product and its purpose:
