The forecast of a G3 magnetic storm Monday night means chances will be good to see the Aurora borealis, better known as the Northern Lights.
Due to the strength of this storm, the aurora might be visible as far south as Oklahoma City and Raleigh, N.C.
The forecast from the Geophysical Institute at the University of Alaska Fairbanks shows the areas that have the best chance of seeing the lights -- including Washington and British Columbia.
The solid green line shows how far south the Northern Lights might be seen on Monday night.

Weather permitting, highly active auroral displays will be visible overhead from Inuvik, Yellowknife, Rankin and Igaluit, to Portland OR, Cheyenne, Lincoln, Springfield, and New York City, and visible low on the horizon as far south as Carson City, Oklahoma City, and Raleigh.
