Northern lights in Bismarck: tonight’s chance

The view from the Missouri bluffs

Bismarck and Mandan face each other across the Missouri, and the river has cut a broad trench through the plains. The bluffs above it, on both banks, are the natural viewpoints for a storm night: from up there the city lights fall away below, and the northern horizon stretches across the Missouri Coteau. Upstream, the river widens into Lake Sakakawea, whose shores northwest of Bismarck are among the darkest places in the central part of the state.

A western sky

Bismarck is in the Central time zone but far to its west, so its clock runs well ahead of the Sun: solar midnight falls closer to 1 am than to midnight, and the dark window on December 15 runs from 6:45 PM to 6:31 AM. The most active hours of the aurora, which SWPC places around local midnight, therefore come later on the clock than in Fargo. The tool's hour strip takes that into account. Weather comes mostly from the west and northwest, and the semi-arid western half of the state is drier than the Red River Valley, though wind is more frequent.

Practical notes for a storm night

Interstate 94 and the river bridges carry most of the area's night traffic, and their lights reach a surprising distance across open country. A gravel section road a few miles north of the interstate is usually darker than a park inside the city. In winter, check the road conditions before leaving: blowing snow can close rural roads within an hour on the plains, even under a clear sky, and the coldest clear nights are also the ones when a stalled car becomes dangerous. Phones lose charge fast in that cold, so keep a spare battery inside your coat.

From here to the border

Every hundred miles north from Bismarck lowers the Kp needed: Minot needs about 4.6. For a strong storm, Bismarck itself is enough; for a weak one, the drive toward the Canadian border or the Turtle Mountains pays off. The North Dakota page lists every town, and the Fargo page covers the east of the state.
