UPDATE: As Mike Smith pointed out: "the high number of strikes in the Upper Mississippi Valley... they had a much worse than normal tornado season in the area and the amount of lightning corresponds to it."
Vaisala, the original lightning detection company that I have profiled before, sent this map showing nearly 310 million lightning strikes on Earth (specifically 309,959,570, they tell me) in the last six months via their Global Lightning Dataset:
The map looks similar to those from NASA's satellite estimates, but because it's only 6 months of data, it doesn't line up perfectly, and these are ground-based, not satellite sensors.
Here's a zoom of the United States. The map shows the density of lightning strikes, with the maximum purple in the Missouri area being 32 strikes per 20 kilometers. You can easily see how mountains (the Rockies & Appalachians) stand out because they have very little lightning. This is because air moving up the mountains from the west drys out, and because the geography disrupts the storms' circulations.

The Atlantic hurricane season of 1996 was a blockbuster season for southeast North Carolina. Could that repeat this season?
Scientifics Direct (formerly Edmund Scientific) has a sea of scientific devices and gadgets in their store, that I could only dream of as a kid!
The worst flooding this week was in Louisiana, but the unnamed low-pressure system dropped 10 inches of rain in eight states.
Here in Pennsylvania, after experiencing months with almost no rainfall and a complete lack of typical thunderstorm activity, the last 10 days have brought daily rainfall and storms.
What may go down in the record books as "The Great Flood of 2016" is now upon us. Over 30 inches of rain has fallen and thousands have been rescued from the floods.
I'm pleased to announce that the 4K version of the 360fly camera has arrived! Unboxing, in-car review, and time-lapse sample videos in this blog.
