Sydney has officially shivered its way through its coldest day in 37 years.

Metropolitan Sydney reached a maximum of just 10.3 degrees today, making it the coldest day overall since 1984.

Elsewhere in NSW blizzards dumped more than half a metre of snow over parts of NSW over the last 48 hours as towns and cities shiver through record-breaking temperatures.

While city dwellers might be struggling through today's icy weather, the conditions are barely comparable to temperatures in regional areas today with Cooma on track to record its coldest day in 17 years with a maximum of just 1.2C.

Mudgee is also on track to record its coldest day in nearly three decades with a top of 4.4C.

The last time temperatures dropped that low was in 1992, when the town recorded a minimum of 5.2C.

In the Central Tablelands, Orange has received its heaviest dump of snow since 2015 with a whopping 16cm falling today alone.

Fresh flakes hit the slopes throughout yesterday, with 15cm to 30cm of snow at some resorts by last night, including Thredbo.

Perisher Valley has already received around half a metre of snow over the last two days with more on the way today.

Snow is also falling across the upper Blue Mountains this morning with Katoomba, Blackheath and Mount Victoria receiving their first sprinkle of snow for the season this morning.

Frost risk is high to severe in most areas across the region with drivers warned of black ice and dangerous driving conditions.

Snow is expected to continue to fall above an elevation of about 900 metres in southern NSW this afternoon, with another 10 centimetres likely in the Alps, according to Weatherzone.

Locations at lower elevations including the lower Blue Mountains and Greater Sydney are forecast to receive showers today with temperatures in the city unlikely to get above 11C.

Drivers across NSW have been warned to postpone travel plans as the severe weather creates treacherous driving conditions in the lead up to the long weekend.
