Northern Lights Poised to Light Up 16 U.S. States Tonight

Forecast Overview

The NOAA Space Weather Prediction Center’s experimental Aurora Viewline tool shows a southern‑most “viewline” for tonight and tomorrow, based on the OVATION model and the maximum Kp forecast between 6 p.m. and 6 a.m. Central Time. A moderate geomagnetic storm is expected as a fast coronal mass ejection (CME) heads toward Earth, raising Kp values into the aurora‑visible range.

Where to Look

According to multiple outlets, the aurora could be visible from Alaska down to Wyoming, covering 16 states in total. Residents in northern parts of the Midwest and lower Great Lakes may catch low‑horizon displays if they are north of the projected viewline.

Timing and Tips

The best viewing window is after local sunset through the pre‑dawn hours. Dark, clear skies away from city lights maximize chances. Look toward the northern horizon; the aurora may appear as faint ripples at the edge of the viewline or as vivid curtains further north.
