Forecast issued at 4:30 am EST on Friday 25 July 2014.
A high over the central Tasman Sea extends a ridge along the Queensland east coast. The high will move slowly eastwards and is expected to be situated over the next few days before starting to weaken. A trough over far southwestern Queensland will move slowly eastwards and stall over the southwest on Friday, then commence moving eastwards once more on Saturday. The trough should move off the southeast coast early on Sunday, while another high develops over central New South Wales in its wake.
Forecast for the rest of Friday
Isolated showers and thunderstorms over the south central, becoming more scattered during the afternoon and early evening. Scattered showers about the coast and ranges between Cairns and Ingham. Possible showers over most of the remaining eastern districts, and also over the central west and eastern tropical inland. Light to moderate southeast to northeast winds over the tropics, tending moderate to fresh northeast to northwesterly over the south, and moderate southwesterly over the far southwest.
Saturday 26 July
The high should continue to move eastwards across the Tasman Sea while a new high develops over central Australia. The surface trough should recommence an easterly motion through the southern interior helping to trigger showers and thunderstorms over southern districts to its east. Isolated showers are likely about remaining eastern districts in an onshore wind flow, with the possibility of isolated showers developing over the central interior as low level moisture feeds in ahead of the surface trough.
Sunday 27 July
The surface trough should move off the southeast Queensland coast early in the morning with the new high extending a firm ridge into northeastern Queensland in the wake of the trough. This should cause isolated showers about the east tropical coast in an onshore wind flow but bring more stable conditions throughout the rest of the state.
Monday 28 July
A high will move northeastwards from central New South Wales, over southeast Queensland and into the southern Coral Sea, maintaining a ridge along the tropical east coast. A few showers should continue in the onshore flow about the tropical east coast. Mostly sunny and warmer than normal conditions will continue throughout most of the state under a stable air mass.
Tuesday until Thursday
The high will move slowly eastwards towards New Zealand, with the ridge weakening but persisting along the tropical east coast of Queensland. A cold front will move eastwards across southern Australia, and is likely to enter into southwestern Queensland late in the period, however a very dry airmass in place ahead of this feature will rule out any significant chance of rainfall.
The next routine forecast will be issued at 4:30 pm EST Friday.
