Australia: your weather for the week ahead 16/5
A classic autumnal airflow takes hold this week, a ridge of high pressure extends out to the east, fog and frost becomes a little more common especially about the New South Wales slopes and ranges, mornings are crisp but daytime temperatures relatively warm, bordering on hot in Sydney, 26 degrees on Tuesday, the May average is 19.5.
But the weather remains unsettled for those in Tasmania and at times southern Victoria. A cold front will push in cloudier, cooler air this afternoon and throughout the evening. As an area of low pressure to the south interacts with the high pressure over the mainland, winds strengthen easing tomorrow morning but the blustery weather continues to batter Tasmania and southern Victoria this week as a string of fronts reach us early Wednesday and Thursday, by the afternoon the colder air behind the final one lowers snow to around 900 metres.
Over the next four days our best chance of rain in the south will be over western and central Tasmania, 4-day models suggest a further 50 to 150 millimetres possibly more. The heaviest rain will fall on Thursday.
Turning our attention to the north, the May transition into the dry season is strengthening, the ridge dominates Queensland’s coast this week, maintaining a showery airflow, but elsewhere it’s mainly dry and warm. Later in the week humidity builds under easterly winds bringing a storm or two to the Top End coast.
