Frosty Math: -35 + 17 = -18

It never fails to astonish me how rapidly the temperature changes here at times: We went to bed at minus 35 degrees and woke to a balmy minus 18. Hardly any wind was noticeable. And the night sky (the darkness extends well into our days at this time of the year) was still clear except for some hazy ice fog over the river.

Addition: By the end of the day we measured (a shocking) minus 5 degrees.
