Thick fog covered large areas of southeast Queensland and northeast NSW on Tuesday morning, including Brisbane.
The combination of clear skies, relatively low temperatures and plentiful moisture in the lower atmosphere caused an abundance of fog in eastern Australia on Monday night and Tuesday morning.

Just one day after Sydney's transport networks were affect by thick fog, visibility was reduced to 100 metres in parts of Brisbane early on Tuesday.
This morning's fog was thickest to the west of Brisbane and over inland areas of northeast NSW, although westerly winds managed to carry some of it towards the coast.
Brisbane Airport only sees about nine fog days per year on average, with a peak in fog frequency between May and July, and again in October. This makes it more fog-prone than Sydney and Adelaide, but not quite as foggy as Canberra, Melbourne or Perth.

The airborne moisture that helped cause this morning's fog should also fuel showers and some thunderstorms in southeast Queensland and northeast NSW this afternoon and evening.
The atmosphere will become even more unstable on Wednesday, with thunderstorms more likely and severe storms possible. Be sure to check the latest warnings over the next couple of days.
