Large parts of inland New South Wales and Queensland have been drenched by heavy rainfall over the past 24 hours, with some places seeing their heaviest falls in almost two years.
A low pressure trough lying over the eastern interior was fed by a deep, moist northeasterly flow, creating heavy showers and thunderstorms.
QLD's Maranoa and Warrego and southern parts of the Central West copped the most widespread and heavy falls.
Charleville picked up 28mm in the 24 hours to 9am, its heaviest daily fall since March. To the northwest of Charleville, Isisford picked up 100mm to 9am, its heaviest rain in a year. Springfield, not to be mistaken with the residence of The Simpsons, recorded 88mm, its largest daily total in almost two years, and for January in a decade.
In NSW, falls were much more isolated, however the Condobolin, Parkes and Forbes area had a widespread 20-to-40mm. Parkes received a particularly torrential thunderstorm early this morning, collecting 77mm to 9am with 5mm falling in 10 minutes. This was also the town's heaviest daily fall since March 2012, and for January in at least 17 years.
A similar weather pattern will cause thunderstorms to persist across the region. However, with the trough edging even further inland, thunderstorms will be focused further west today and tomorrow with potential for a further 20-to-50mm, with isolated higher falls.
Over the weekend, the pattern will break down significantly, with only the odd thunderstorm expected with much lighter falls.
