Flash then light

I brought the dog outside this morning and looking to the southeast around 5:30am, I saw a flash of light that looked like a lightning bolt in a perfectly clear sky. But a well-defined flash of light - a zig zag pattern about 6 inches relative to extending your fingers apart to the sky. After the flash, a bright white, round light traversed the sky heading northwest in a straight line but at different speeds at times. After it passed directly overhead, I saw another dimmer white object moving perpendicular to the first object heading south-southwest. Much fainter than the first, blurry-like. This one moved at a consistent pace. After they were out of view, I went inside and immediately checked online to see if the first object was the International Space Station, but I do not think it was visible this morning in my location. I am just an educator who always looks up at the sky, with or without a telescope. My love for astronomy came after taking an astronomy course in college. And this experience is the first time I have felt compelled to report what I saw.
