As we have mentioned before, a large sun storm erupted Tuesday leaving a lot of energy heading toward earth. This energy will cause the northern lights or aurora borealis to flare up in the northern hemisphere. Here is the two cents on how the auroras happen: Atoms in the upper atmosphere are stirred when energy from the sun hits the poles, this causes them to collide with magnetic particles and that process emits light. That light then travels the magnetic field of the earth.
This all leaves areas as far south as Chicago capable of seeing the northern lights. This energy is still being felt as we head into Friday so there is a decent chance to see them again in cities like Minneapolis, Seattle, Bismarck and Fargo. The image below is a forecast for the auroras, the darker green means a better chance of seeing them between sunset and sunrise.
If you are traveling to the northern portion of the country you only have one more day to view them, on Saturday they will retreat farther north and only Alaska will be left with a good chance to get a glimpse of the northern lights.Forecast for the northern lights on Saturday morning.
