I checked the weather situation, there is a large area of low cloud over the motorway route north of Voronezh and south of Moscow, which would be in the convoy’s interest more so than the air force (perhaps this was part of their planning). Of course this may not be much of a factor if the air force has access to ground spotters.
Basically a small low east of Moscow and fronts lie further south, keeping some low cloud in place all day probably. It is around noon local time there.
