Wait for dark.

Tonight's peak is forecast around Kp 5.0 (Minor storm). The forecast still depends on darkness, cloud and the moon at your exact spot.

What Kp does Wisconsin need?
Eau Claire is the easiest place in Wisconsin to catch the aurora — it needs Kp 8 or above before the oval climbs into view, which happens a handful of nights a year, in strong storms. Milwaukee needs Kp 9+. A high Kp is never the whole story though: you also need darkness, clear sky and little moonlight.
