When lightning hits a power line, the surge causes a circuit breaker to open, which is why you lose your power. A device called a protective relay will sense the opened breaker, and after a brief time interval, will reclose the breaker. If the fault hasn't cleared, the breaker will open again. After a longer time interval, another closing will be tried. If the fault is still there, then the breaker is kept open until a crew can investigate the problem. Most faults, such as lightning, are momentary. This is an oversimplification; the idea here is that most faults can be cleared automatically.

Sometimes lightning strikes the poles. Sometimes the wind knocks the poles over. Sometimes it just hits a transformer and causes a surge. It does not usually just come back by itself--it rquires someone to fix something. It may be as simple as closing a breaker, but it could be putting a pole back up.

During thunder storms there are a leaders that travel from cloud to ground and ones that travels from ground toward cloud. When they connect there is a larger brighter lightning bolt. This travels from ground to cloud. If the bolt comes from power lines or pole it draws the electricity from the wires and you have that momentary blackout.

I have heard that if there is a lot of wind the powerlines sometimes actually touch each other (or get close enough to arc), causing a temporary drop out or flicker.
