Weather for the weekend of 21 - 22 January 2012

Updated 20/1/2012

A high in the Bight is moving slowly east and is expected to be south east of Tasmania by Sunday evening. Meanwhile, the trough off the south east coast that caused this week's rain will linger through the weekend and a second trough, currently lying from the Kimberley to Victoria will remain largely stationary and fill by Sunday evening. It appears this trough is decaying faster than expected and so the thunderstorm risk for the weekend has receded considerably.

About 10 - 15mm of rain has fallen around Dalby in the last seven days, with the area around Chinchilla receiving somewhat more (62mm). The Goondiwindi (86mm) area received higher falls. NOAA is forecasting the possibility of very light rain only for the weekend. With the CAPE below 500J/kg and the SLI of -1C to -2C, there could be occasional light thundery showers associated with towering Cu.
