The area languished in single digits throughout Sunday, peaking at a measly 8°C.

Not even getting to the forecast maximum temp of nine.

This made it the lowest maximum temperature recorded in June at the Mudgee Airport weather station since 2007.

On June 27 that year, the mercury topped out at 6.7°C.

Sunday’s chiller undercut a couple of cold June days in recent years at the weather station, with 2016 and 2011 both dipping as low as 8.1°C.

Although it was still clear of the record for the location, the coldest top temp of the sixth month of the year being 5.2°C on June 11, 1992.

The cold change didn’t bring much in the way of rain to Mudgee, with just 2mm in the gauge as of 9am on Monday morning.

Gulgong collected 10 times that over the same period.

According to Weatherzone.com.au the culprit was a large pool of cold air from the Southern Ocean that surged across southeastern Australia between Friday and Monday, causing a mix of wintry weather in multiple states.

While this wasn't a record-breaking cold snap, it did cause colder weather than recent years in some areas and brought remarkably heavy early-season snow to the alps.

The coldest air arrived on Saturday and Sunday, allowing snow to fall down to about 600 metres above sea level in parts of Victoria, NSW and the ACT.

According to Weatherzone's Ben Domensino, between June and August, outbreaks of snow, rain and brisk winds are to be expected as cold fronts sweep over Australia's southern states.

“The system that affected southeastern Australia on the weekend was notable for its feed of cold air from unusually high latitudes. A high pressure ridge extending from the Great Australian Bight all the way down to the fringes of Antarctica created an avenue for polar air to traverse the Southern Ocean and reach Australia,” he said.

Residents living in high country around Oberon, Black Springs and Shooters Hill woke to a whiteout on Sunday morning following heavy snowfall overnight.

The snow that had been predicted all week by the Bureau of Meteorology arrived right on schedule around 9pm on Saturday. Bathurst's top of 5.4 degrees on Sunday was its equal second lowest maximum temperature of the last 10 years.

Roads between Oberon and Bathurst were closed on Sunday morning, leading to Group 10 cancelling of all of Sunday’s Round 10 games.

However, the cold snap did little to budge the so-far above average temps the local area has experienced throughout June 2018.

Mudgee’s average top for the month is over a degree above the norm, while the overnight figure is 0.7 up.

Which when combined with the 15.4mm of rain received to date, is still in line with the Bureau of Meteorology’s 2018 Winter Outlook for warmer and drier than average conditions.
