Why does sunlight fan out from gaps in clouds?

Phil Krause  asked the Naked Scientists:
   
Hi Chris
 
The sun is around 93 million miles away and emits light in all directions so the rays are not parallel.  However, by the time they reach us they are very close to parallel, or should be.  I have noticed that when we have partial cloud cover and the sun starts to peep through them the rays sometimes fan out like they are generated from just behind them rather than from the sun.

What do you think?
