The gust front arrived only shortly after I got out of work (just a mile south of the Kent County Airport) at five o'clock. It was moving fast, but I had my camcorder ready to go, so I parked on little side road, got out of the car, and started recording. I won't hazard a guess at the wind speed; I'll just say I wouldn't have wanted to be near any trees. I filmed what could have been a gustnado, could have been just blowing dust--won't know till I view the footage this evening. But the most impressive thing was the lightning: close, intense, and non-stop, some of the most earnest I've seen in quite a while. I moved back inside my car after the first couple of close encounters.
After the gust front had passed, I headed for home, where I changed into some shorts and paused long enough to pull up doppler on my computer and consult the target discussions. Then I hopped back into my car and headed east down I-96. I passed through the storm near Lansing and positioned myself on an overpass east of the city, but at that point the storm samed pretty docile, just your garden-variety Michigan squall line, with nothing like the wind or lightning I witnessed earlier.
