A weak trough that swept across the region on the 3rd triggered some isolated showers around the Brisbane Metropolitan area.
On the 4th and 5th, a rain band extended along an upper level trough from the northern part of the state and delivered some moderate to locally heavy falls over northern Brisbane before easing to isolated showers on the 6th, and cleared off the coastal region on the 7th.
Isolated coastal showers persisted for the next few days before returning to fine weather conditions on the 11th.
Affected by a middle level trough over the central interior of the state, isolated showers or thunderstorms continued over the northern parts of Brisbane on the 15th.
Another more significant surface trough approached from the west on the 18th and isolated showers affected the western and southern suburbs. Showers increased from isolated to scattered and delivered some moderate falls over the Brisbane region on the 19th before contracting to the Sunshine Coast area on the 20th and 21st.
The coastal ridge extended from a high over the southern Tasman Sea and reached its peak on the 24th, generating isolated showers, chiefly near the coast, which persisted through to the 27th.

A Monthly Climate Summary is prepared to list the main features of the weather in Greater Brisbane using the most timely and accurate information available on the date of publication; it will generally not be updated. Later information, including data that has had greater opportunity for quality control, will be presented in the Monthly Weather Review, usually published in the fourth week of the month.
This statement has been prepared based on information available at 10 am on Wednesday 1 December 2010. Some checks have been made on the data, but it is possible that results will change as new information becomes available.
Averages are long-term means based on observations from
all available years of record, which vary widely from site to site.
They are not shown for sites with less than 9 years of record, as they cannot then be calculated reliably.
The median is sometimes more representative than the mean of long-term average rain.
The Rank indicates how rainfall this time compares with the climate record for the site,
based on the
(very low rainfall is in decile 1, low in decile 2 or 3,
average in decile 4 to 7, high in decile 8 or 9
and very high is in decile 10).
The Fraction of average shows how much rain has fallen this time as a percentage of the long-term mean.
