Details

During the first three weeks of the year there was little rainfall recorded in the Brisbane region.  Cloudy conditions with patchy rain on the 2^nd, associated with an upper trough over southeast Queensland, brought falls of less than 9 mm to parts of the Brisbane metro area.  Showers along the southern Queensland coast in the onshore southeasterly flow on the 3^rd again brought falls of less than 9 mm to parts of the Brisbane region.  These were largest daily falls recorded for the month until a cloud and rainband associated with an upper trough brought falls of between 16 and 34.9 mm to the Brisbane metro area between 9am on the 22^nd and 9am on the 23^rd.  After the cloud band moved north during the afternoon and evening of the 23^rd, showers persisted over the Brisbane region in a moist onshore flow.  Shower activity then increased about the region on the 25^th as a ridge built over southeast Queensland and the low level flow tended east to northeasterly.  Showers continued in the moist onshore flow on the 26^th and 27^th, easing a little on the 28^th and 29^th but persisting until the end of the month.
