The heat wave has broken, at least here in Michigan. A cold front finally moved through earlier this morning. Yesterday the temperatures were in the mid-90s and the humidity was high. Even at night the lows were only into the 70s and the dewpoints stayed high.
I had hoped to watch some of the lightning and thunderstorms roll through last night. But the storms were moving west to east, just north of Ann Arbor. I could see the lightning on the horizon but not much more. Investigating the National Weather Service web site I finally found the online location to download images. Now I just need to merge these with some GIS software and get some nice pictures.
