Forecast Overview
The National Oceanic and Atmospheric Administration’s Space Weather Prediction Center (NOAA SWPC) has issued a forecast indicating a low probability of aurora borealis visibility in seven U.S. states on the upcoming Tuesday and Wednesday, with a high probability in Alaska. The prediction covers the same two-day period for all listed locations.
Scientific Explanation
Auroras occur when solar wind—streams of charged particles released by solar flares or coronal mass ejections—reach Earth’s magnetosphere. The particles then collide with atmospheric oxygen and nitrogen, producing luminous ribbons of varying colors that appear in the night sky. NASA describes the resulting displays as “bright ribbons of light” moving across the horizon. Recent years have seen the phenomenon visible farther south more frequently, a trend linked to heightened solar activity.
Expected Visibility
According to NOAA, the states with a chance of seeing the lights are:
- Alaska – high likelihood (particularly northern regions)
- Idaho – low likelihood
- Minnesota – low likelihood
- Montana – low likelihood
- North Dakota – low likelihood
- South Dakota – low likelihood
- Washington – low likelihood
- Wisconsin – low likelihood
The low-chance states lie near the U.S.–Canada border, while Alaska’s northern areas remain the most favorable viewing zone.
Agency Outlook
NOAA’s Space Weather Prediction Center emphasizes that aurora visibility depends on clear, dark skies and minimal light pollution. The agency’s forecast is based on real-time solar wind measurements and magnetospheric models. NASA’s public outreach materials reiterate that the intensity and reach of auroras are directly tied to the strength of incoming solar particles.
Public Interest
Julia Gomez of USA TODAY notes that increased aurora sightings have sparked heightened public curiosity and tourism in northern regions. Observers are encouraged to monitor local weather conditions and seek locations with minimal artificial lighting to improve chances of witnessing the display.
