A strong geomagnetic storm will produce northern lights in nearly two dozen US states on Saturday night, the National Oceanic and Atmospheric Administration (NOAA) prediction states. The forecast map and typical aurora visibility patterns during a G3 storm show that states from the Pacific Northwest to the Northeast will see the aurora borealis under favorable weather conditions.

The aurora could be visible tonight and early Sunday in the northern U.S. states and even into the lower Midwest, according to the NOAA/NWS Space Weather Prediction Center.

A period of peak magnetic storms on the sun could lead to another show of northern lights on Earth on Saturday and Sunday, forecasters say.
