Wife and I just noticed a flash of lightning outside and a couple seconds later heard thunder and our lights flickered like we were going to lose power. What is happening here?

Could be that lightning struck a distribution line. There are lightning protection systems that activate when the line voltage goes way too high, as will happen during a lightning strike. When this happens, all the energy on the line is dumped to earth, interrupting the flow of power. As soon as the strike is over and the voltage falls below a certain point the lightning protection equipment stops conducting electricity and power begins to flow again.
