A POOL of cold air will spread over NSW this weekend, bringing some of the coldest weather so far this year and even a bit of snow.
April is typically the time of year when NSW starts to see big temperature swings.
Being the middle month of autumn, Australia is still surrounded by some of the warmest sea surface temperatures of the year.
This warm water acts to insulate the continent and helps keep the air temperature up.
Right now, the water surrounding Australia is even warmer than usual, which is causing even more warmth than we would typically see in mid-autumn.
Last weekend, a tongue of hot air drifting over Tasmania caused Hobart to reach 32.3 degrees, which was the city’s warmest April day on record.
