It was +5 f. degrees Sunday. At church Lubov, who speaks English, cheerfully announced, "It's warm today! But tomorrow it will be cold again." Our -25 temperatures make us appreciate a balmy +5.
Inside homes, stores, missionary apartments, and our office it's plenty warm. We mostly work in shirt-sleeves. Missionaries dress to be warm enough when they're out in -20f. (with wind) and still be comfortable inside at +72 degrees on any given day. Layering is the answer!
Sister Allcott took winter pictures of all the zones; Yekat Zone here.
