Some U.S. residents may have a rare chance to see the aurora borealis, more commonly known as the northern lights, late tonight and into early Wednesday morning.

While the best viewing will be across Canada, including Edmonton and Winnipeg, the lights will be visible in parts of Alaska. The lights will also be visible in Portland, Ontario, Canada, which means they could be seen in upstate New York.

AccuWeather.com Expert Senior Meteorologist Paul Walker said it will be cloudy along the St. Lawrence River on New York's northern border, while hit-or-miss showers could occur in southern New England in the early evening.

The lights may also be seen as far south as Madison, Wis., and Lansing, Mich. Walker said that this corridor will also be partly cloudy with some hit-or-miss storms.

The Geophysical Institute at the University of Alaska, Fairbanks maintains an "aurora forecast." Its forecast suggests that while the aurora activity will be moderate on Tuesday, it will be "active" Wednesday and Thursday.

AccuWeather.com's astronomy blogger Lisa Beightol said the northern lights are actually the result of coronal mass ejection. Beightol described CME as "blob of solar material" that is thrown into space after an explosion on the sun.

According to NASA, the CMEs are huge clouds of charged particles that fly away from the sun so quickly, they can travel 93 million miles to Earth in just three or four days.

When the charged particles of the CME interact with the Earth's magnetic field, a geomagentic storm can occur. The solar particles of the CME interact with nitrogen and oxygen in Earth's atmosphere and create red and green colors.

NOAA is projecting a 10 percent chance of a major geomagnetic storm and a 45 percent chance of visible aurorae.
