Sydney's warm morning will be spoilt by a gusty cold change today, bringing welcome showers to thirsty gardens and parks.
Those living near the city woke up to a mild morning, with the temperature reaching 21 degrees by 9am, five degrees warmer than usual. In the west, overnight temperatures were cooler. They decreased enough for fog to form, reducing visibility to just 150 metres at Campbelltown and Bankstown early in the morning.
After the warm morning, cloud cover will increase over the city ahead of a cool change today. Southwesterly winds will bring noticeable cooling, with showers expected to develop from early in the afternoon and into the evening. Around five to ten millimetres of rainfall is expected, and there is also a risk of afternoon thunderstorms for eastern suburbs. Winds will be fresh to strong at times, so choose a rain jacket over an umbrella if you want to stay dry.
These showers will bring an end to what has been a dry month for Sydney. Only 1.4 millimetres of rain has been recorded in the city before today, well below the average September rainfall total of 69 millimetres. This follows on from a dry August, with the month's total of 19mm amounting to less than a quarter of the long term average.
Looking ahead, a high pressure ridge will bring lighter winds and clearer skies on Friday and into the weekend. Friday and Saturday should both reach around 20 degrees and Sunday will be a bit warmer.
