A lightning flash is a sudden, huge flow of electricity. This will produce an equivalent, instantaneous, huge magnetic field. The flux related to the field will cut through (link with) any conductor in the vicinity and induce an emf (voltage). It is the current fluctuations caused by these induced emfs that you see as flickering of lights.
If there is a direct lightning strike on electrical equipment then physical damage could be caused, or switch-gear tripped, which may result in longer power loss.

The lightning (often 50,000 volts) overloads circuits on poles or at the the power station and they cut out to protect the lines from melting.
Or it actually hits the pole and breaks the line. A flicker is when it is near the line but doesn't break it.

Usually because a transformer is hit by lightening, that the Utility Company has to replace! That's why it may take some hours for lights to come back on.
Flickers can be caused by the interruption of the current during a storm.
