Wisconsin Summer Storms

In summer, the skies over Wisconsin come alive. The cells build through a warm afternoon, and everyone on the field keeps one eye on the radar. Pilots know the feeling—watching a line march in while you decide whether to launch, wait, or tie down.

This collection captures that: a Wisconsin VFR sectional in day and night versions, with the radar drawn the way you remember it standing under an open sky—green, then yellow, then a wall of red lined up on the horizon.

If you've ever camped beside your airplane and watched that line roll in, you don't need the rest explained.
