For many across Australia, this year is the one that winter forgot. We are currently half way through July and with temperatures hitting the high teens and low 20's across the southern states, no one would think they are in the middle of the austral winter. So far Sydney has seen three days in a row hitting the 20 degree mark and will continue to do so until Friday. If that eventuates, it will be the first time that residents of the Harbour City have seen five consecutive days above 20 degrees in July since 1928 and only the second time in 154 years of records. But good things don't last forever, especially when it comes to weather. A vigorous low currently sitting over the Bight will bring gusty winds and showers to all capital cities in the south as it sweeps across southeastern Australia from today. Perth was lashed first yesterday by this system with wind gusts of up to 111 km/h recorded along WA's southwest coast. Adelaide will be hit later today, Melbourne on Thursday with Canberra and Sydney following on Friday. The temperature change won't be dramatic as the cold airmass will lag behind the front. None-the-less, the period from Friday 19th through to Monday 22nd will see the coldest widespread snap for southeastern Australia so far this season. With such seasonal weather, this weekend might be a good one to celebrate the Australian tradition of Christmas in July.
