I just returned from chasing the cell that developed in Grand Rapids. Interesting to get home and read these discussions, but having just looked at the radar, I'm wondering how things have fared for those of you to my east. It's certainly turned into an active weather night.
When I took off after the Grand Rapids cell, it was pretty much the only thing going on the radar, barring one little dude just initiating to the southwest. The GR storm hadn't yet developed the hook mentioned previously, but it had gone from a fleck of red to a healthy triangular shape, it was nice and isolated, and I figured I had nothing to lose.
I caught up with the storm somewhere around the Belding area and chased down M57 east as far as M66. There were a few lowerings right about where they should have been to be interesting, and the storm seemed fairly well orgranized, but it lacked steam. I wonder how it would have done with a little more CAPE.
On the way back, I could see more storms developing to my south and southeast. With twilight disappearing, the clouds glowed dim white against a clear, starry sky, putting on a nice display of lightning. Beautiful. This was a pleasant way to spend a Monday evening.
