Focus of heavy rain moves to NE NSW

Exceptionally cold temperatures in an upper trough that moved across NE NSW and SE Qld today combined with strengthening southeasterly winds to produce heavy rain on the coast from Brisbane south to Grafton. The small low that developed off the north Queensland coast yesterday continued to move SE, tightening the pressure gradient as far south as the Illawarra coast. Alstonville, 10km WNW of Ballina, recorded 130.4mm in the 2 days ended 9am Monday, and there were some periods of heavy rain in the area. Ballina Airport registered 51mm and Evans Head 50mm in the 6 hour period to 3 this morning, while Coolangatta Airport had an isolated downpour of 53mm between 1 and 3pm. Gale force winds were reported from exposed coastal stations this morning and again later this afternoon from Double Island Point north of Brisbane to Jervis Bay south of Sydney.

The axis of the trough of cold air which as been responsible for the unusual rainfall event in Queensland over the past few days crossed Brisbane tonight. The 10pm radiosonde balloon launched at the airport found a temperature of minus 49.1 at 300hPa, about 9.3km above sea level. This is 9.8° below the June average, a remarkably large departure so far above the surface.
