Northern Lights Forecast: Aurora Visible in 9 States Tonight

Northern Lights Forecast: Could You See the Aurora Tonight?

If you live near the U.S.-Canada border, tonight might be a good time to step outside, tilt your head toward the sky, and hope for a splash of green or purple light dancing on the horizon. A new northern lights forecast suggests there is a "low" chance of seeing the aurora borealis in up to nine U.S. states on Saturday night. While a low-level forecast isn't the most dramatic aurora event of the year, it's still a meaningful opportunity for skywatchers in the right locations — especially those who have never witnessed this natural phenomenon before.

In this guide, we'll break down everything you need to know about tonight's aurora forecast, which states have the best chance of seeing the northern lights, what a "low" forecast actually means, and how to maximize your chances of catching a glimpse of one of nature's most stunning light shows.

What Does a "Low" Aurora Forecast Actually Mean?

Aurora forecasts are measured using the Kp index, a global geomagnetic activity scale that runs from 0 to 9. A Kp index of 0 to 2 is considered quiet, while a Kp of 5 or higher is classified as a geomagnetic storm — the kind that produces widespread, vivid aurora displays visible far into the continental United States.

A "low" forecast, generally corresponding to a Kp index of around 2 to 3, means that aurora activity will be mild and largely confined to high-latitude regions. In practical terms, this means the northern lights will primarily hug the horizon and will only be reliably visible in areas very close to the Canadian border. The displays may be subtle — faint glows or low arcs of greenish light rather than the dramatic curtains of color often seen in photographs.

That said, even low-level aurora activity can produce beautiful sights under the right conditions, and camera sensors are far more sensitive to auroral light than the naked eye. Astrophotographers with modern smartphone cameras or DSLRs often capture stunning aurora shots during Kp levels that appear underwhelming to the unaided eye.

Which 9 States Could See the Northern Lights Tonight?

The states most likely to have a viewing opportunity during a low aurora forecast are those that sit along or near the U.S.-Canada border. These typically include:

Washington — The northern reaches of the Cascade Range and areas near Bellingham offer dark skies and a favorable latitude for aurora viewing.
Idaho — Northern Idaho, particularly the Panhandle region, regularly appears on low-level aurora watch lists.
Montana — One of the most aurora-friendly states in the lower 48, Montana's wide-open landscapes and low light pollution make it a top destination for skywatchers.
North Dakota — The flat terrain of North Dakota provides unobstructed northern horizons, ideal for spotting low-hanging aurora arcs.
Minnesota — Northern Minnesota, including the Boundary Waters Canoe Area Wilderness, is one of the premier aurora-watching destinations in the country.
Wisconsin — The northern tip of Wisconsin, near Lake Superior, occasionally catches aurora activity during low forecast events.
Michigan — Michigan's Upper Peninsula, surrounded by the Great Lakes, is a beloved aurora hotspot among Midwest skywatchers.
New York — Far northern New York State, particularly the Adirondacks and areas near the St. Lawrence River, can sometimes see faint aurora activity.
Maine — Maine's northern and coastal regions round out the list, with Aroostook County being especially well-positioned geographically.

Tips for Seeing the Northern Lights Tonight

Even with a favorable forecast, seeing the northern lights requires a bit of planning and patience. The difference between a successful aurora sighting and a frustrating night of staring at a blank sky often comes down to preparation. Here are the most important factors to keep in mind.

Get Away from Light Pollution

Light pollution is the number one enemy of aurora viewing. City and suburban skies wash out faint celestial displays, making it nearly impossible to spot low-level aurora activity. Use tools like the Dark Site Finder map or the Light Pollution Map app to locate dark sky areas near you. Driving even 30 to 40 minutes outside of a major metropolitan area can make a significant difference in what you're able to see.

Check the Weather Forecast

Cloud cover will block your view entirely, regardless of how strong the geomagnetic activity is. Before heading out, check a reliable weather service for cloud cover forecasts in your area. Clear or mostly clear skies are essential. If your immediate location looks cloudy, consider driving to a nearby region where skies are expected to be clearer.

Time Your Viewing Window

Aurora activity is generally strongest in the hours around local midnight — typically between 10 p.m. and 2 a.m. local time. This is when your location on Earth is most directly facing the polar regions where aurora activity originates. Setting an alarm and heading out during this window gives you the best chance of catching peak activity.

Use a Camera to Your Advantage

As mentioned earlier, cameras detect auroral light far better than human eyes. If you're unsure whether you're seeing a faint aurora or just atmospheric haze, take a 10-to-30-second long-exposure photo pointing north. If there's an aurora present, it will almost certainly show up in the image even if it's invisible to the naked eye.

Monitor Real-Time Aurora Apps

Apps like SpaceWeatherLive, My Aurora Forecast, and the NOAA Space Weather Prediction Center website provide near-real-time updates on geomagnetic activity and aurora visibility. Setting up notifications on these platforms means you won't miss a sudden spike in Kp activity that could turn a quiet night into a spectacular one.

Why Aurora Season Matters

We are currently in a period of elevated solar activity known as Solar Cycle 25, which is approaching its solar maximum — the peak of the sun's roughly 11-year activity cycle. This means that geomagnetic storms and strong aurora events are becoming more frequent and more intense compared to just a few years ago. Skywatchers across the Northern Hemisphere have already witnessed some remarkable displays in recent months, with aurora visible as far south as Texas and Florida during the strongest events.

Even on a low-forecast night like tonight, staying aware and heading outside is worthwhile. Solar activity can shift quickly, and what starts as a quiet evening can sometimes escalate into a memorable display with very little warning. The key is to be ready.

Final Thoughts

Tonight's northern lights forecast may be rated "low," but for the millions of people living in the nine border states with a viewing opportunity, it's still a reason to look up. Whether you're a seasoned aurora chaser or someone hoping to check the northern lights off your bucket list for the first time, the conditions tonight offer a real — if modest — chance at witnessing one of the planet's most breathtaking natural spectacles. Dress warmly, find a dark spot, point yourself north, and keep your eyes open. The sky just might put on a show.
