Ulaanbaatar faces a sharply cold night, with the forecast putting the temperature at minus 11. The bulletin keeps the message to a single line: overnight in the capital, 11 degrees of frost. Readings like that are unremarkable for Mongolia as the cold season sets in, when air from Siberia pushes night temperatures well below zero. The gap between daytime highs and nighttime lows can be wide at this time of year, and residents plan around it. Cold at this level means icy sidewalks in the morning and heating systems running at full tilt. City drivers and pedestrians both feel the change once temperatures drop this far. Night temperatures at minus 11 call for warm clothing and a bit of patience until morning.
