Northern Michigan and the Upper Peninsula could see the aurora overhead Thursday night, July 2, under a NOAA Space Weather Prediction Center forecast.
A G1 geomagnetic storm is expected to lift the Kp index to 4.67, with isolated G2 periods possible as CME activity tied to an X1.1 solar flare continues.
Farther south in Michigan, the lights would more likely sit on the northern horizon rather than directly overhead, making dark-sky locations the best viewing spots.
NOAA said G1-G2 conditions could persist into July 3 pending further analysis of the coronal mass ejection, extending a broader multistate aurora window flagged earlier this week.
