Brisbane in November 2014: A hot month; severe thunderstorms lash the city


Very hot conditions predominated throughout the month, with the most notable days on the 15th and 16th. On the 15th, Amberley recorded its hottest November day in 74 years, and averaged for the month, its warmest days, warmest nights and warmest mean temperatures on record. Archerfield and Logan City also had their hottest November day on record on the 16th. Monthly maximum temperatures at Amberley were more than 3 °C above average, and between 1 °C and 2 °C above average at Brisbane City and Airport. Overnight temperatures at all metropolitan sites were more than 2 °C above their long-term averages. 

Thunderstorms observed on the 6th, 19th, and 27th generated the majority of November rainfall totals. Flash-flooding occurred around the Brisbane Metropolitan area on the 19th when a line of severe thunderstorms tracked through the city. Extremely high hourly rainfall rates were observed around Inala and Geebung. On the 27th, another severe thunderstorm caused extensive damage to Archerfield, southern suburbs, the Brisbane CBD and some northern suburbs as the super cell tracked north-northeast. Flash-flooding, destructive winds and very large hail were observed, with extensive structural damage in South Brisbane and the Brisbane CBD. Archerfield had a wind gust of 141 km/h, and received its average monthly rainfall in one day. Brisbane city and Archerfield Airport also recorded above average monthly rainfall.

In contrast, Amberley recorded 10.8 mm for the month, its lowest November rainfall in 20 years and Logan City received only half its monthly average and Redcliffe fared a little better. Near-average monthly rainfall was recorded at Brisbane Airport.

Notes

A Monthly Climate Summary is prepared to list the main features of the weather in 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.

A Climate Summary is generally published on the first working day of each month.

This statement has been prepared based on information available at 9 am on Monday 1 December 2014. Some checks have been made on the data, but it is possible that results will change as new information becomes available.

Averages for individual sites 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 10 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 decile ranking (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.

The ACORN-SAT dataset is used for temperature area averages.
