Fog blankets parts of NSWDrew Casper-Richardson, Saturday April 15, 2017 - 10:32 EST
Residents in some inland parts of NSW awoke to a thick blanket of fog on Saturday morning.
Fog formation is reliant on three main factors: cooling temperatures, light winds and moisture. A high pressure system brought mostly clear skies overnight which allowed the atmosphere to cool and kept winds light. This combined with ample moisture in the lower atmosphere allowed for the development of fog on Saturday morning.
Fog was thickest around inland parts of the Illawarra, Southern Tablelands and Northern Tablelands. Moss Vale had visibility drop to 50 metres just before sunrise with fog persisting until at least 8am when visibility was still restricted to 150m. Elsewhere visibility dropped to 100m in Armidale and 500m in Goulburn. Parts of western Sydney also had a foggy start to the day. Visibility fell to 100m in Richmond and 400m in Camden.
Fog had burnt off soon after 8am as the sun warmed the surface. The high pressure system responsible will bring similar conditions on Sunday morning with fog likely in similar locations, making the Easter Bunny's job a little bit harder.
