A cool change sweeping across New South Wales could see temperatures plummet by up to 10 degrees in some areas following a sweltering spell of early summer weather.
The state’s capital experienced sizzling conditions over the weekend, with heatwave warnings issued as bushfires raged across NSW.
Examining Tuesday’s temperatures, Sky News Weather Presenter Emma Wightman said the mercury rose to nearly 32 degrees in Sydney, while parts of the city’s west nudged 38.
Elsewhere in NSW, Wilcannia in the state’s north-west recorded 38.6 degrees on Tuesday and Bourke, further north, reached a scorching 40.1 degrees.
Looking ahead at Wednesday’s outlook, Wightman explained there was “some relief on the way” for those affected by the heat.
“A southerly change arriving overnight Tuesday and into Wednesday will bring that relief, particularly across eastern parts of the state,” she said.
As the cool change sweeps through the region, Wightman explained temperatures could plummet by as much as 10 degrees in some areas.
“Sydney and Gosford both heading down to 26 degrees on Wednesday. However, it will remain very warm in northern and western parts of the state,” she said.
“Bourke again heading for a top of 42 degrees, 39 in Cobar, even Canberra staying very warm at 33 degrees.”
