NSW foggy facade
Parts of New South Wales woke to a blanket of low cloud and fog this morning, reducing visibility dramatically.
The Slopes and Tablelands were worst affected with visibility being limited to less than 50m at Armidale and Lismore and 100m at Moree. Meanwhile, Orange turned to white as residents struggled to peer more than 150m.
Closer to the coast, Grafton, Port Macquarie and parts of Great Sydney saw patchy fog, while locations west of the ranges included Tamworth, Walgett and Corowa.
Calm conditions beneath a high pressure ridge can be held responsible for this fog event, with clear skies allowing cool air to settle close to the Earth's surface. Moisture in the air cool and condensed as a result, allowing fog and low cloud to form.
As the sun came up and the temperature rose, the droplets in the air re-evaporated or 'burnt off' revealing a beautiful blue sky day.
Fog remains a risk early hours of the coming mornings preceding a gusty front early next week.
