Fine weather prevailed on the Ranges in the first half of the week with three days of sunshine and temperatures in the high twenties brought in by a northwest airflow. At 3.00am on Thursday morning winds backed to the south-east resulting in a sudden drop in temperature with maximum struggling to reach twenty degrees. For the remainder of the week an upper level trough generated isolated showers and in some locations moderate falls were reported but of short duration.

The equatorial trough is now well defined to the north of mainland Australia, and cyclone development may follow before the end of December

On Monday morning the 5^th there was a sudden drop of five degrees in the maximum temperature when winds veered to the south east from a high in the south Tasman Sea. On Wednesday an east coast low developed off the Queensland coast as an upper level trough in a northwest cloudband  started to drift eastwards across  the southern interior. This resulted in some good ground-soaking much needed rainfall. Instability in the atmosphere increased on Thursday when the first of three days of thunderstorms brought some substantial fall of rain. Total rainfall so far this the month has exceeded the average rainfall for December.

La Niña conditions have strengthened across the tropical Pacific and BOM suggest it will peak next month and last until the end of summer. An above average rainfall is even more likely as a result.
