Parts of eastern New South Wales have woken up to their coldest
morning since spring, causing thick fog in some places.
Newcastle recorded an overnight minimum temperature of just 10
degrees, three below average and the coldest temperature recorded
since November. It was also the coldest morning in five months for
Scone and Tocal, cooling to seven and ten degrees respectively.
The low temperatures this morning also caused widespread fog to
develop. In Sydney, visibility was reduced to just 50 metres in
Richmond, which cooled to 11 degrees, and 150 metres in Campbelltown.
To the south, visibility reached 100 metres in Moss Vale, while
further north in Armidale it reached 150 metres. Other foggy centres
this morning included Moruya, Lismore and Bathurst.
The cold morning was produced br a high pressure ridge over the state,
which caused clear skies and light winds. This allowed heat to radiate
away from the ground overnight without being inhibited.
Friday and Saturday mornings will also be cool for parts of Sydney and
the Hunter as the ridge remains in place. Looking ahead, a low
pressure trough will bring cloud from the west on Monday, preventing
nights from becoming as chilly.
