How Cold Is It?

The thermometer reads -15 along the Mississippi in Muscatine as I write this. How cold is -15?

The hydraulic part of the storm door was almost frozen. I could barely push it open and as i pushed the door open, I slammed into the door.
I was wearing two sets of gloves to scrape the cars, yet my finger tips started to tingle after two minutes.
Blocks of ice were as solid as bricks.
I saw a squirrel stuck to a metal bird feeder.
The snow is blue.
All of the windows in my home are frosted so I can't see out.
We are hoping for a high of -8 today which will feel like summer.
All of the eagles have vacated the area.
Air hangs when people talk like cartoon balloons.
I could use an icicle as a razor to shave.
I can hear HNI machinery 2 miles away.
In 1932 Niagara Falls froze completely.
I have a lot to be thankful.
