Welcome to the start of another year of forecasts! I looked back at the forecasts from 12 months ago, which were all very wet - I am so glad we did not get the wet summer the Bureau suggested could happen again this year.
A high in the Bight is moving slowly eastwards, followed by a developing low with associated cold front. As the high moves east, it will ridge up the east coast and this pattern will last through to late Sunday, when the ridge will slip offshore ahead of an advancing troughlinked back to the low around Tasmania.
Isolated rain has fallen through the area in the last seven days, wtih the only notable falls being Wandoan 21mm, Drillham 12mm and Brigalow 5mm. Isolated thundery rain could occur leading up to the weekend, but at this stage the weekend looks to be rain free.

Dalby 34C
Stability A
Convection Dry convection to 10,000ft with cloud base at 9,500ft
Wind NE @ 5kts shearing to 160/5 at 6,500ft and then increasing to 190/15 at 10,000ft
There will be some very high cloud about, but it should not affect convection. Shear wave is possible.
Sunday 8 January 2012
Dalby 37C
Stability B
Convection Blue convection to 9,500ftwith some wispy cloud
Wind N @ 5kts with 190/5 at 6,500ft and then increasing to 200/15 at 10,000ft
There will be very high cloud about and it may be thick enough to partially suppress convection in places. Shear wave is possible.
