A BLOCKING PATTERN IN THE TASMAN LIKELY TO BRING ANOTHER RAIN EVENT TO THE EAST.

A big burley high pressure system is currently ridging through southern WA bringing warm sunny weather to the west and central parts of the country. But as it approaches the southeast inland, it is driving onshore winds and showers to the southeast coast of the mainland and Tasmania.




That activity should ease and skies likely become partly cloudy this weekend over the southeastern corner of the country.


Up over QLD, a band of rain and thunderstorms over the northern third of the state will continue to drift offshore over the coming 24-36hrs.


As the high moves eastwards over the weekend, it should become sunny and cool to mild in the east. The weather over in the west will become warm to hot and mostly sunny this weekend in easterly winds.


The high pressure system will move into the Tasman Sea during Monday and this is where we will see showers developing along the NSW and QLD coasts. Some indications that this activity may become heavy at times with a blocking pattern setting up.






Note once the high gets into the Tasman Sea, it become stuck, thanks to tropical activity to the north pushing down on this ridge, keeping it in place. That will allow the wet spell over the east once again to become quite productive.




As a consequence, any frontal activity trying to make an approach to the east is driven south into the southern ocean, meaning the dry spell for SA will continue.
