Cloud and rain has limited Brisbane's temperature to 19.1 degrees so far today, putting the city on track for its coldest December day since 1888. 20mm of rain had drenched the city between 9am and 3pm, while the associated cloud cover had blocked out the warming rays of the summer sun. The highest temperature recorded after 9am in Brisbane was 19.1 degrees, which is around 10 below average for the month of December. The main Brisbane weather site only has 12 years of continuous records, but checking surrounding sites from the city and the old regional office site, the current maximum of 19.1 would be the lowest recorded since 1888(assuming we stay at or below 19.3 until 9am on Thursday). The rain is going to stick around for the city through Wednesday night and there is a risk it will become even heavier for a period during Thursday morning. This will depend on the precise position of a small low pressure centre that is currently tracking south towards Fraser Island. The rain should ease into Friday as the low moves away, leaving Brisbane with some sunny breaks and a more summer like maximum of 27 degrees. Even warmer but showery weather is likely on the weekend.
