Some rain on the way for NSW

Kim Westcott, 28 July 2019

While a slow-moving low and trough will reach southern New South Wales on Monday, don't expect too much in the rain gauge.

It has been a dry month for many NSW towns, with Brewarrina and Smithville in the Upper Western yet to report any rain this month. Not far behind, Broken Hill, Mudgee, Merriwa, Glen Innes and Canberra have all recorded less than five millimetres so far.

Rainfall deficits over the past several months have seen some dam storage heading on the downward path, with Warragamba sitting at 52% full, while last year it was 70% full.

The upcoming trough will bring a 1-5mm across the south, with some parts along the border potentially picking up 10-15mm on Monday. By Tuesday, most of the rain will slip east, with some fortunate places about the coast and ranges picking up 5-15mm. Rain will head to the northeast on Wednesday and Thursday, and dissipate by Friday.

The rainfall outlook for August suggests that there is a 30-40% chance of exceeding median rainfall for southern and eastern parts of the state. There is a higher chance for northwestern parts of the state to exceed August rainfall, however average August rainfall is typically quite low for the Upper Western and Northwest Slopes and Plains.
