Northern Lights Forecast for Grand Forks

Yes. At 47.9°N on open prairie, Grand Forks gets the aurora from weaker storms than cities further south. In the strongest storms the Grand Forks Herald has run photos of it over the Sorlie Bridge downtown.

City lights hide the fainter nights. For those, drive ten to twenty minutes north toward Manvel or west to Kelly's Slough, where the farmland runs flat to the horizon.

Yes. It is about 22 miles west of Grand Forks on Highway 2 near Arvilla, and The Forum has photographed the aurora there over a prairie meadow and over the Turtle River. The park sits in a wooded valley, so for a low display in the north walk out of the trees to open ground. In winter there are packed trails and a warming hut by the sledding hill.

Yes, from the parking area and the viewing deck. The refuge is about 12 miles west of Grand Forks, roughly a 15-minute drive, among flat wetland and farmland. Public access is limited to the parking lot on the east boundary and the short trail to the raised deck. The rest of the refuge is closed, and drones are not allowed. The county roads along its edge are the other option.

Cold enough to plan around. January lows in Grand Forks average about −3°F and February lows about 1°F, and the city's record is −43°F, set in January 1912. The aurora is not only a winter sight here, though: displays have been photographed in September and May, well outside the deep-cold months.

In Grand Forks, you usually need at least Kp 5 to have a reasonable chance of seeing the northern lights. Lower Kp can still bring a faint aurora display low on the northern horizon, but it is less common.

This is based on magnetic latitude, and Kp index is a global geomagnetic index, so treat it as a rule of thumb, not a location-specific guarantee.

Tonight, the NOAA Kp index forecast is 1.6 to 2.7. That is below the usual Kp index threshold for Grand Forks, so seeing the aurora is unlikely.
