Pulsing bright blue light flashing across sky, producing a visible blue line along path of travel

I was driving in a neighborhood of Dayton MN, delivering papers when I saw what looked like a shooting star. I looked back at it again once I realized it was still traveling in the sky a moment later, and it was flashing bright blue pulses of light and produced a visible bright white/blue line along its path of travel. It lasted for about 2-3 seconds, and partially lit up the sky and illuminating the cloud cover as it disappeared behind some rain clouds.
