Spring had almost sprung.
After a run of warm and sunny days, Sydney will make a brief return to wintery conditions today with cold winds making the city feel close to freezing.
Possible showers have been predicted for the Hills this weekend but a return to sunnier conditions is expected next week.
Bureau of Meteorology duty forecaster Dmitriy Danchuk said temperatures are expected to get cooler as the day progresses.
"For Sydney for today we're expecting temperatures within the 13 to 16 degrees range, but in the middle of the day I wouldn't be surprised if it feels like temperatures slightly above zero."
The bureau has issued severe weather warnings for gale force winds along the NSW coast, as well as high seas and damaging surf.
"Beach conditions in these areas could be dangerous and people should stay well away from the surf and surf exposed areas," the warning said.
Mr Danchuk said there had also been overnight reports of snow in the Blue Mountains and in Orange, in the state's central west.
There was heavy snowfall near Nimmitabel and Bombala, in the Snowy Mountains, with local police warning of possible road closures and treacherous conditions.
"Anyone travelling through the Snowy region needs be mindful of the extreme risk posed by ice and snow on the road surface and drive to the conditions," Monaro Local Area Command duty officer Inspector Chris Varley said.
Mr Danchuk said the cold conditions were being caused by a dip in a low pressure system in the southern Tasman Sea.
"So today we will have almost simultaneous increase in the winds and waves and, on top of that, there will be general brief cooling."
The winds are forecast to continue over the weekend, with isolated showers forecast for Sydney tomorrow and Sunday.
