(Chalky, pen) As part of my weather-nut activities I have just discovered that in Jakutsk, Siberia, the current temperature is -50°C. Minus fifty. Not a breath of wind but a thin fog. Wrap up well.
(Chalky) Parts of it, yes. Jakutsk is a large and quite agreeable city. All the buildings are on stilts about six feet high so the heat from them doesn't melt the permafrost. In the brief peaky summer it's warmer than London and very sunny.
