Extremely bright blue light traveling slightly upwards before disappearing and leaving a trail in the sky.

My fiancee and I were sitting at the entrance of the Frontenac State Park Campground at 3:05 AM CST, photographing the perseids meteor shower facing mostly NE over the Mississippi River. We both observed an extremely bright ball of blue light (it lit up the sky for a brief moment) appeared in the sky, SE of our location. It traveled a short distance, traveling horizontally with an upward trajectory, lasting 2-3 seconds, before emitting an intensely bright light and completely disappearing from view. It left behind a trail, resembling smoke/clouds, which was light in color, that lasted approximately 10-15 seconds before it dissipated. No sound was heard during the event. The sky was very clear with very little to no light pollution from surrounding cities.
