I once read that if you finish a windmillbuild it will be no wind for 3 weeks.
I am guessing the same thing goes for lightning detection devices.
Last night it was forecasted a thunderstorm and at 9pm things were looking very promising.
It was even heading in the right direction!
Skip forward one hour and the ligtningstorm stops dead in the water 90 miles out...

I'm throwing a small picture in the files from the lightningtracker at 10pm last night.
