Not quite those same "post frontal" conditions .... but I did find out, many decades ago, that Crappie will bite in some rough water conditions. We were fishing Douglas Lake, down in NE Tenn, when the changing weather put us out on the main lake in whitecap conditions. Trolling motor was only strong enough to keep the boat turned sideways in the wind/waves. We actually were letting the wind blow us back towards a creek, with the idea that we could get out of the wind/waves once we got around the point at the mouth of the creek. Rather than reel all our lines in, we elected to just let them drag behind us, off the side of the boat. Our minnow rigs (hook/sinker/minnow) couldn't have been more than a few feet under the surface of the waves, as we were likely being blown along at 2-3mph & our lines were stretched out almost at a 90deg angle Still, we managed to hook & boat several nice Crappie before reaching calmer waters. We returned back to the heavy chop of the main lake, several times, and allowed the wind/waves to push us across the lake ... and boated several more Crappie in the process.
That's the only time I can remember something like that happening, under those conditions. "Speed Drifting" is a good name for it
