Snow replaces near-record September heat in NSW

Ben Domensino, Thursday September 14, 2017 - 10:47 EST

Winter-like weather has returned to NSW following a burst of early spring heat on Wednesday.

Residents living on parts the central and southern ranges in NSW woke up to a light cover of snow this morning.

A few areas of the Barringtons Tops and Oberon Plateau saw enough snow to turn the ground white, while flakes were also reported falling at Blackheath and Lithgow in the Blue Mountains and down to Jindabyne in the Snowy Mountains.

The wintry morning in central NSW was a stark contrast to yesterday's brief pulse of summer-like heat.

Oberon's maximum temperature on Wednesday was 21 degrees, which is seven above average for this time of year. This morning, the mercury dipped to just one degree, allowing snow to settle in the region.

Sydney's top of 33.8 degrees yesterday was the city's warmest day on record this early in spring and the fourth warmest September day in 158 years of records. Sydney is forecast to reach 18 degrees today, which is a whopping 16 degrees cooler than yesterday.

Large fluctuations in temperature are common during September. This is the time of year we see warm air building over central and northern Australia clashing with cooler air surging north from the Southern Ocean.

Fortunately, today's cooler weather is helping reduce fire danger ratings across most of the state, assisting the NSW RFS in keeping fires contained.

Yesterday's hot and windy weather caused the state's first total fire bans and emergency warnings of the season. Unfortunately, they won't be the last.
