Ice Fog Alert

Look quick and you’ll see real live ice fog. 

Ice fog is any kind of fog where the droplets have frozen into extremely tiny crystals of ice in midair. Generally this requires temperatures at or below −35 °C (−30 °F), making it common only in and near the Arctic and Antarctic regions. It is most often seen in urban areas where it is created by the freezing of water vapor present in automobile exhaust and combustion products from heating and power generation. Urban ice fog can become extremely dense and will persist day and night until the temperature rises.

Yes, I know it looks like regular fog. What did you expect?

I’ll be back with the last weather reporting post later today. Thanks to those of you who have already sent me your weather information. If you haven’t yet me your link, now’s the time.

The main street cam seems to have frozen (temporarily, I hope) at 9:52 AM, so it’s not real live ice fog. Sorry about that.

 

Here’s what not-so-live (but still real) ice fog looks like.
