Let’s play find the front! Here’s a radar grab from a few minutes ago that shows a front draped across Michigan, Indiana and Illinois, as seen with accompanying showers and thunderstorms, and nocturnal migrant birds launching off behind it across Wisconsin, Iowa, Minnesota, Missouri, Kansas and so on. The strong southerly flow ahead of the front makes for poor flight conditions and although the winds behind it are only mostly calm that means it’s good enough to get on the move. As we enter September I’ll be watching the weather like a hawk for both these nocturnal movers and the diurnal raptors soon to spread across our sunny skies.
