Overview of the Aurora Borealis Forecast
A G2 geomagnetic storm is anticipated to bring the northern lights, or aurora borealis, to parts of the northern United States from March 19 to March 21, 2026. This event is triggered by a coronal mass ejection (CME) that occurred on March 16, sending charged particles toward Earth. The National Oceanic and Atmospheric Administration (NOAA) has issued a storm watch, indicating that conditions may allow the auroras to be visible as far south as Illinois and New York.
Key States for Aurora Viewing
The NOAA forecasts that up to 18 states could experience auroral displays, particularly in northern regions. The states most likely to see the northern lights include:
- North Dakota
- Minnesota
- Montana
- Washington
- Idaho
- Wisconsin
- Michigan
- Vermont
- New Hampshire
- Wyoming
- Iowa
- Nebraska
- New York
The best viewing conditions are expected to occur between 10 p.m. and 2 a.m. local time, with the peak activity likely occurring late at night.
Viewing Conditions and Recommendations
For optimal viewing, individuals are advised to find locations with minimal light pollution and a clear view of the northern horizon. Weather conditions, however, may pose challenges; cloudy skies and precipitation could obstruct visibility in some areas, particularly in Michigan, where forecasts predict rain and snow.
To enhance the chances of capturing the aurora, skywatchers should consider using smartphone cameras in night mode, as they can detect colors that may not be visible to the naked eye. A tripod or stable surface is recommended for clearer images.
Official Statements & Responses
Shawn Dahl from NOAA stated, “Yes - there is potential for the aurora to develop tonight (Thursday), tomorrow night (Friday), and even the next night (Saturday) - if we do observe the anticipated storm arrivals.” This highlights the uncertainty surrounding the exact timing and strength of the auroras, which depend on the magnetic orientation of the incoming CMEs.
Criticism & Opposition
Despite the excitement surrounding the auroras, some meteorologists caution that visibility is not guaranteed. Dave Salesky, a meteorologist, noted that “not a great chance if you’re west of the Cascades” due to expected cloud cover in those regions.
Conflicting Reports & Gaps
While NOAA's forecast suggests a Kp index of 6, indicating strong geomagnetic storm conditions, some reports indicate that visibility may be limited by local weather conditions. The variability in forecasts underscores the unpredictability of auroral displays.
What's Next
As the geomagnetic storm unfolds, skywatchers are encouraged to monitor live forecasts and updates from NOAA and other space weather resources. The potential for auroras may continue into the following nights, depending on the ongoing solar activity.

This rare opportunity to witness the northern lights offers a captivating experience for many across the United States, particularly as the spring equinox approaches, a time known for increased auroral activity.
