A quick check of the weather app radar showed the storm about an hour away +/-. It had been a very hot day, and I hoped the cloudcover and barometric pressure change (if there was one) would get the fish feeding. I got to a local public pond around 7pm.
Who knows if there was any difference...but I did catch some fish. I flyfished with a blockhead popper, and caught ~6 bass and 2 hybrid sunfish. The biggest bass measured 19", which is pretty good for Iowa. The very next fish sprinted for deeper water, and broke my line.
As soon as I saw some huge lightning streak across the sky overhead, I decided it was probably time to head home.
