6 orange glowing balls in the sky

My friend and I were in my backyard. She went out to her car and yelled that there was something in the sky. I looked up and there was what looked like a bright orange ball in the sky. She yelled " there is another one" then another and another. Approx 45 seconds later I looked up and two more were coming. It appeared they were following each other. All going in a straight line. It was getting cloudy and they disappeared in the clouds. They appeared to be coming from the Southwest side of town going East.
