Heavy rain drenches western NSW

Ben McBurney, Wednesday June 12, 2013 - 13:02 EST

Widespread heavy rain has soaked inland New South Wales overnight, with many places seeing their best rain in around a year.

Across large parts of the state's inland there were widespread falls of 10-20mm in the 24 hours to 9am today. However, those that saw thunderstorms gained even larger totals, with up to 50mm falling in some places.

This has provided great follow-up rain to earlier this month, with many parts now seeing well above their mean June rainfall.

Menindee collected 39mm to 9am, its heaviest June fall since 1952. This brings the town's monthly total to 76mm, almost four times the average and its wettest June since 1923.

Pooncarie received 28mm, its wettest June day in three years. This also brings its monthly total to 76mm, its wettest for June in eight years.

Cobar recorded 29mm, its heaviest daily June fall since 2009 and brings the town's monthly total to 64mm. This is almost twice its June average and its wettest in over a year for any month.

The cause of a the widespread rain has been a low pressure system and associated trough combining with high moisture levels. The system is crossing eastern parts of the state today, bringing further widespread heavy rain and storms.

While the system will move offshore by tomorrow, unstable southwesterly winds in the wake of the low will bring further showers on Thursday and Friday over the region, although totals will be much lighter.

Looking into the weekend, a cold air mass and a high pressure ridge will push over the state, causing cool but generally sunny days followed by cold and frosty nights.
