Visibility IV / V
I was just getting home from the city when I noticed a spectacular cloud formation flowing from the northern Näsijärvi behind the apartment building. Of course, the phone's battery flickered just as I was trying to take a panoramic picture of the revelation, but I still got one flicker before that. I hurried up to get the right camera, but when I got back out, the cloud was already moving at a good pace and the showy leading edge was no longer visible. The cloud was accompanied by a characteristic gusty wind and small drizzle.
