What does scary dark look like? (Courtney)

The below shot was taken out our window at 4pm. I said to Marcus, "It's really scary dark outside." "What's scary dark?" he asked...

That is scary dark! And shortly followed a massive thunderstorm and lightening show which lasted on and off for about four hours. We don't get storms like that in Melbourne! I actually found myself wondering if we were unaware of some sort of tornado warning.
