While still up in the suburbs with my mom, Kate and I took a flash card to the local Walgreens to get some prints made of some digital photos. It was sunny and warm and windy when we were walking through the parking lot, with the gray of a coming storm off in the southwest.
We weren't in the store for more than five minutes before we heard people commenting on how it was pouring rain all of a sudden. Walking back outside to have a look, it wasn't just pouring, it was a complete deluge, with a very, very strong wind blasting the rain into a mist that blew everywhere, even under the fairly well protected vestibule of the drug store. Lightning and crashing thunder was frequent, and the power in the store flickered a few times. The wind had the trees bent way over and there were frequent gusts.
On the way home, we passed a short stretch of road, maybe about a quarter mile, where there were a LOT of tree limbs down, at least one entire tree lying across part of the road, and construction debris like Tyvek, insulation, and plywood scattered everywhere. From the narrow damage swath, plus the fact that the sky was covered in cumulonimbus mammatus, I thought, hmm... tornado? But no mention of tornadoes was made, just a lot of talk of wind damage and hail, so it was probably a microburst causing an exceptionally high wind gust over a fairly small area.
It was definitely an awesome storm, though. Got me at least a little out of the bad mood I was in yesterday.
