Unexplained Flashes in the sky NNJ (Daytime)

I have actually been noticing a phenomenon that I have never seen before in my lifetime. I would really appreciate someone with alot of knowledge to help me understand what it is I am actually seeing.

The past week on my way to work in and around the same area I have been noticing flashes in the sky that make no sense. To describe what I am seeing imagine the flash of light you recieve after bumping your head, I really want to say its lightning flashing horizontally in the sky but the line is to perfect and to fast going east to west as if it were some sort of force field....yeah yeah, I know, no such thing, I am just trying to describe this to the best of my abilities so that I can actually get some real concrete proof on what this is I am seeing.

If anyone can help, the area and times I am seeing this is: Rt 23 Riverdale, NJ between 7:30- 8:45am, I have noticed this everyday with only seeing the flash once on each day.... Have any clues anyone???

well its doesn't sound like heat lightining kinda weird
