Parts of northern New South Wales have seen 50 to 100mm of rain during the past three days, making this the wettest stretch of days in July for decades.

Moist northeast winds have been feeding large amounts of moisture into multiple low pressure troughs over the state during this past week. The final trough of this wet period is slowly contracting north and east over New South Wales, which will allow rain to ease through the day.

During the past 24 hours, the New England region has gained widespread falls of 15 to 30mm, adding to the 40 plus totals we have seen over the area during the past few days. For some, this rainfall over the last three days has doubled the entire monthly average.

Inverell recorded 32mm in the 24 hours to 9am this morning, bringing the three day total to 84mm. This was Inverell’s heaviest July rain over a three day period since record began in 1950. Guyra has had its wettest stretch of July days in at least 30 years, receiving 89mm over the past three days.

The high moisture levels and extensive cloud cover has also led to warm nights. Overnight temperatures in the state’s north remained five to 11 degrees above average, a warm change after a frosty start to the summer.

As the trough continues it’s slow migration into Queensland today rain will ease from NSW, with less than 15mm expected anywhere. From Sunday, a high pressure ridge will take over, leading to drier conditions and cooler nights next week.
