Who we are
Northern Lights Tonight is an independent US English forecast publisher. We built the site for people who want a local decision, not a dramatic national headline or a single Kp number with no context. Our pages explain the evidence behind each answer and say when the available data is too weak to support one.
What GO, MAYBE, and NO mean
The tool combines aurora reach, darkness, cloud cover, and local viewing limits in a fixed gate order. GO means conditions line up well enough to try. MAYBE means a display is possible but an obstacle matters. NO means a special trip is not justified by the current signals. UNKNOWN means we do not have reliable enough data to guess. These labels are practical judgments, not guarantees or percentage probabilities.
Where we publish forecasts
Wave 1 covers 15 forecast pages across selected US states and cities: Colorado, Ohio, Indiana, Michigan, Chicago, Seattle, Wisconsin, Massachusetts, Maine, Minnesota, Illinois, Oregon, Utah, Alaska, and Fairbanks. Coverage is intentionally limited while we verify that each local page has a useful headline point, timezone, nearby places, and viewing guidance. A place without a dedicated page can still be checked through the Near me tool without creating another indexed forecast URL.
Sources and independence
Aurora activity comes from public NOAA Space Weather Prediction Center products, including OVATION and Kp. Cloud-cover data is adapted from Open-Meteo. Northern Lights Tonight is not affiliated with, endorsed by, or operated by NOAA. We describe our gate order and freshness rules on the methodology page so readers can judge the tool rather than take a verdict on faith.
