How come that on t minus 3min there is a weather no go? Anyone knows how this works...

Anyone know how they detect lightnings? Is it just cameras, or do they have planes flying around?

Earlier quoted context omitted.
A forecast doesn't stop a popup thunderstorm from entering the no-go zone.
Of course not. But it would help SpaceX plan and prepare much more in advance than 3 minutes. There is certainly a cost associated with getting everything set up, and then postponing the launch. Could they have planned for this earlier and not got everything ready?
Probably not. They were a go up until just three minutes before launch. I doubt any extant or near-future forecasting system is able to tell you that a specific storm cell will be in a specific spot at an exact minute all that far in advance.

Well, this is exactly my plan, and I'm going to do it ASAP. Prototype should be done by summer. There are millions of little weather stations all over Florida that nobody is using (smartphones). By connecting those stations together and pulling the live sensor data into forecasts, I do in fact believe that these small thunderstorm cells should be very well-forecasted if we take in this dense dataset.
This forecast system doesn't exist yet, you're right. But it should exist in the next couple months/years, and when it does, it should be able to provide this kind of forecast.
BUT only if that is worth money to a group like SpaceX - is it? That's really my question. I know I can build the technology, but will anyone like SpaceX buy, and at what price?

This specific delay though was caused by convective clouds being too close to the launch. This was probably determined with either ground based radar, or visible/IR images from satellites.

There is a considerable body of research on detecting the presence and range of lightning: http://en.wikipedia.org/wiki/Lightning_detection
