In Chelyabinsk the air is good right now (approximate, US EPA scale). From 10:00 to 21:00 local time the city mean PM2.5 rose from 1.5 to 5.0 µg/m³.

Light wind (1 m/s) in the evening or at night, as the air cools, possibly traps particles near the ground (a temperature inversion). Cold weather (4°C) possibly means more heating, a common source of particles.

Weather now: clear, 4°C, wind 1 m/s, humidity 64%. No major change in the wind is expected in the coming hours. By 10:00 the temperature will be about 1°C.
