The effects of a coronal mass ejection—a bubble of plasma that bursts from the sun’s surface—will likely impact Earth’s magnetic field on Saturday, bringing the northern lights to several northern U.S.

The agency expects a minor or greater geomagnetic storm—a disturbance of Earth’s magnetic field—on Saturday, which increases the likelihood of northern lights displays being visible to more people, as the effects of a recent coronal mass ejection reach Earth, according to NOAA’s three-day forecast.

The National Weather Service has issued a winter weather advisory for the Sacramento area until Sunday at 4 p.m., with wind gusts up to 55 mph and a 70% chance of rain, and the Placerville area expecting 4 to six inches of snow.

The colorful northern lights may reveal themselves to a wide swath of Americans Friday night due to an impending solar storm forecast to reach Earth.

Another display of the northern lights could be visible this weekend in several U.S. states following a severe solar storm. The National Oceanic and Atmospheric Administration Space Weather Prediction Center forecast a planetary K-index -- which characterizes the magnitude of geomagnetic storms - of five out of a scale of nine for Friday and Saturday,

A coronal mass ejection earlier this week may pull the northern lights to more northern U.S. states, forecasters said.

Sky gazers in several U.S. states could get a colorful glimpse of the northern lights as we enter the weekend, thanks to a recent geomagnetic storm.

Millions of Americans could witness the stunning solar light show in different states over the weekend as a higher-strength geomagnetic storm passes overhead.
