While walking toward the hill from which I planned to shoot Kista Science Tower from a distance I noticed a nice raincloud in the distance. When the sunset peeked out from underneath it turned from nice to beautiful. I started shooting it with my 55-200 tele, then switched to the 18-55 wide angle lens and finally ended up using the 10-20mm ultrawide. Through all of this I failed to draw the obvious conclusion about what was about to happen: If a rainstorm is getting bigger, it is most likely heading towards you and you are about to get soaked.
I was still in happy denial when the first raindrops hit, but soon they started coming in force and I just ran back to the nearest overpass to wait out the shower.
