Full Breakdown
Northern Lights Expected Across 20 U.S. States
3/19/2026, 1:54:28 PM
Anticipated Viewing Conditions
A significant geomagnetic storm is set to enhance the visibility of the northern lights, or aurora borealis, across approximately 20 states in the United States on the night of March 18 into the early morning of March 19, 2026. The National Oceanic and Atmospheric Administration's (NOAA) Space Weather Prediction Center has indicated that this event will be particularly notable due to the upcoming spring equinox on March 20, which is expected to amplify auroral activity. The best viewing times are projected to be between 10 p.m. and 2 a.m. local time, although this may vary based on specific locations and weather conditions.
States with Viewing Potential
The states with the highest likelihood of witnessing the northern lights include:
- Alaska
- Washington
- Idaho (northern region)
- Montana
- North Dakota
- South Dakota (northern region)
- Minnesota
- Wisconsin
- Michigan (entire state)
- Maine (northern region)
Additionally, states such as Oregon, Wyoming, Nebraska, Iowa, Illinois, New York, Vermont, and New Hampshire may also have opportunities for viewing, albeit with potentially weaker displays. Residents in the northernmost parts of Indiana, Ohio, and Pennsylvania might catch a faint glimpse if conditions permit.
Weather Considerations
While the geomagnetic storm promises an exciting light show, weather conditions may hinder visibility. For instance, in Michigan, forecasts predict significant cloud cover and possible snow, which could obstruct the view of the auroras. Similarly, Iowa is expected to experience 60-85% cloud cover on the night of March 18, although conditions may improve later in the night.
Understanding the Northern Lights
The northern lights are caused by the interaction between charged particles from the sun and gases in Earth's atmosphere. When these particles collide with atmospheric gases, they produce colorful displays of light, typically in shades of green, pink, and red. The intensity and color of the auroras depend on the type of gas involved and the energy exchanged during these collisions.
Viewing Tips
For optimal viewing of the northern lights, it is recommended to find a dark location away from city lights. Observers should look northward and be prepared to wait, as the lights often appear in waves. Utilizing apps that track aurora forecasts can also enhance the chances of witnessing this natural phenomenon.
Conflicting Reports & Gaps
While NOAA predicts a G2 geomagnetic storm, local forecasts in states like Michigan and Iowa suggest that cloud cover may significantly limit visibility. This discrepancy highlights the uncertainty in weather conditions that could affect the viewing experience.
