According to the SWPC, the Northern Lights could be visible as far south as The Quad Cities area this weekend.

This is a really exciting possibility, as the Northern Lights are rarely visible in the QCA. Although it looks like I-80 is close to the cutoff line of visibility. For best possible viewing conditions, drive north away from the ambient light of cities and you could be in for a spectacular view from space. They may be visible tonight, but Sunday night is the peak time for viewing.

According to the Washington Post, a giant solar flare erupted from the surface of the sun on Friday night, and the result could be a epic nighttime show for us across the country.
