With sunshine finally peeking out from behind the clouds in Sydney this Saturday after prolonged cold and rainfall, it's hard to believe that yet more rainfall is expected during the next few days. Especially since this has been the city's coldest and wettest week this late in the year in decades. For the seven days ending 9am on Thursday 11th of October, 105mm of rain had fallen in the gauge at Observation Hill, while the average maximum temperature was 19.1 degrees for this period. That makes it the combined wettest and coldest week this late in the year since late October 1981. The week in question was also colder and wetter than July, August and September of this year combined. Many parts of New South Wales remain gripped by drought, but most stations in the Greater Sydney Region have already received nearly twice their long-term average monthly rainfall. Observation Hill has received 120.2 mm as of 9am on Saturday 13th October, and more rainfall is imminent. A high pressure system in the Tasman Sea is directing northeasterly winds onto the eastern seaboard of Australia, maintaining enough moisture along the coast and adjacent interior to bring intermittent showers. Rainfall is set to commence once more during Saturday afternoon, and intermittent showers will be a constant companion during the next few days. It's likely that another 20-30mm will have fallen by Tuesday afternoon, before a more complex system inland begins to make its way towards the coast. It remains to be seen how this system will impact rainfall, but afternoon thunderstorms on Wednesday cannot be ruled out at this stage.
