Drenching rains, chilly days here to stay

Some capitals have just seen their coldest day all year accompanied by pouring rains. If you’re now hoping for sun, you may be unlucky.

The drenching rains that have begun pouring over Australia’s east coast this week are showing no sign of abating, at least for the next few days.

Sydney is looking at more than 50mm of rain heading into the weekend while Brisbane could see possible thunderstorms today. Perth too will be wet and stormy.

In the south, it won’t be particularly warm either with the mercury struggling to get any higher than the teens.

Yesterday was the coldest day of the year so far in three cities – Melbourne, Canberra and Sydney. The capital could only peak at 12.9C at the hottest part of the day.

Rain has now settled in over the east coast. The seas off Port Macquarie, on the mid north coast of NSW, saw a series of dramatic waterspouts late yesterday. Bega, in the state’s south, reported 115mm in the gauge in the 24 hours to 9am this morning. That’s its heaviest one day rainfall for five years.

“It’s all being generated on the east coast by an upper level cold pool,” Sky News Weather meteorologist Alison Osborne said.

It’s basically a blob of cold air, much chillier than the air surrounding, it that is straddling NSW and Queensland.

“This pool of cold air is well into the upper atmosphere, around the cruising altitude of a jet.

“That cold air aloft contributing to enhanced rainfall and storm activity from inland parts of northern NSW to southeastern Queensland,” Ms Osborne said.

Lingering rain on east coast

Brisbane is looking at a very wet day for the rest of Wednesday with a possible storm but clearing later. That should lead to a run of mostly dry days. Temperatures topping out a 22C today and then heading towards 27C for the rest of the week and into the weekend.

The rain could linger into Thursday on the Gold Coast. Dry and warm further north in the state with Townsville seeing maximums of 28C on Thursday.

“Further south and the system as it moves out to sea will generate quite vigorous onshore winds bringing heavy rainfall for the NSW coast today and then again tomorrow,” Ms Osborne said.

In Sydney, there could be very little let-up in the wet weather until the weekend with 25mm possible on Wednesday, similar conditions on Thursday and then a top up of around 10mm on Friday. Temperatures should get to only 17C on Wednesday but then into the mid-twenties. Overnight lows of 14-16C.

Wet and possibly stormy for northern NSW for in areas such as Grafton and Coffs Harbour. But the falls could be heaviest on the south coast of the state with Bega looking at 50mm on Thursday and 20mm on Friday.

Canberra would also see a soggy few days but it should dry up on Friday continuing into the weekend. The mercury will rise from high of 14C on Wednesday to 21C on Friday with minimums of 8C sinking to 5C on Saturday.

Drier in south, wet in WA

It will be dry in much of Victoria although some of that moisture will creep into the Gippsland region.

Melbourne is looking at no rain with highs of 17C and lows around 10C for the coming days. Hobart will see similar weather but could be a touch warmer with highs of 20C on Friday.

Adelaide will remain dry and cloudy until Saturday when some light showers could pass through. Maximums around 20C with lows getting to below 10C early on Thursday.

Heavy rain continues to march across Western Australia in a wide band from the Pilbara down towards the Wheatbelt and Goldfields.

Perth has seen some very rainy conditions with 46mm recorded in the 24 hours to 9am Wednesday.

Around another 20mm could fall on a wet Wednesday with a possible storm. More showers for Thursday before the moisture recedes. Mild highs of 22C and lows down to around 14C.

Dry in Darwin, as befits the season. Blue skies, maximums of 33C and dawn minimums of 22C.
