Cloud associated with ex-Tropical Cyclone Penny is now northwest of Townsville. The outflow from this system is streaming southeastwards.
A line of convective cloud stretches over much of far north Queensland and from western Queensland though northeast New South Wales is along a surface pressure trough.
A middle to high-level disturbance is responsible for an area of cloud, and thunderstorm activity over the top end of the Northern Territory.
A middle-level disturbance is responsible for an area of cloud, now mostly over southern Victoria extending to the Tasman Sea.
Low cloud is affecting parts of Tasmania, eastern Victoria and southeast New South Wales in an onshore airstream.
For Queensland, a trough will move north from the Townsville coast along the North Tropical Coast today and should then shift to the Peninsula coast during Saturday.
A high chance of showers and thunderstorms will extend over northern districts today with some heavy falls likely with thunderstorms, particularly about the coast and ranges near the trough. Heavy falls will then shift to the Gulf of Carpentaria coast during Saturday and contract further into the Northern Territory early next week.
There is the very high chance of showers and thunderstorms over areas north of about Burketown to Townsville with some heavy falls likely with thunderstorms, particularly over the ranges and about the coast and nearby inland between about Tully and Rollingstone.
There is also a medium to high chance of showers and thunderstorms extending further south into the Gulf Country and northern interior, with the slight to medium chance over western districts. Showers and possible thunderstorms about the coast and nearby inland between Proserpine and Townsville, decreasing from the south.
Isolated thunderstorm activity is occurring over western Queensland to the east of an inland surface trough. This trough will shift further west during Friday and Saturday, with the chance of storms gradually contracting further west with it.
The slight to medium chance of showers over the remaining east coast and nearby inland, more likely over the central coast. Fine and mostly sunny over the southern central and southeastern interior.
Temperatures will remain generally a bit cooler than average over central districts and the eastern tropics during the next couple of days in an onshore wind flow and under cloud cover.
