Parts of New South Wales have chilled over the past couple of nights as autumn starts to take a hold.

Overnight temperatures about inland parts of the state are beginning to fall as the change of the season becomes more evident. A broad region of high pressure over the last two nights has led to clear skies allowing the mercury to drop well into single figures.

Parts of the Central/Southern Tablelands and Southwest Slopes and Plains have generally seen the coolest minimum temperatures state-wide over the past two nights.

Oberon chilled to just 3 degrees in the wee hours of Monday morning, falling 6 degrees below the monthly average. The Central Tablelands town then backed it up by cooling again this morning to just 5 degrees – 4 degrees below average.

The story continues as the night air at Goulburn Airport cooled to a two-day mean minimum temperature of just 4.5 degrees which is 5.5 degrees below average for February.

The ingredients for low lying fog were favourable about the Southwest Slopes and Illawarra districts early this morning where visibility was reduced to less than 900 metres about Camden and Albury.

Cool temperatures, high relative humidity and still air allowed fog to gather about low lying regions before it promptly burnt off as the mercury rose with the sun. Goulburn Airport showed one of the more dramatic temperature changes this morning with an increase of 4.2 degrees in just half an hour.

Temperatures are set to continue rising into the high-twenties and mid-thirties about the state today with generally clear skies under a building ridge of high pressure.
