Falls of 40mm-60mm have been welcomed in areas where drought has ravaged the landscape for many months.
According to weather reporting and forecasting service Weatherzone, a slow-moving low pressure trough interacting with an upper-level pool of cold air has produced showers and storms in Australia's eastern inland this week.
Wilcannia's 65mm during the 24 hours to 9am on Monday was its heaviest rain in four years. Griffith's 44.6mm during the same period was its heaviest April rain in more than 60 years.
During the 24 hours to 9am on Tuesday, Queensland's Cunnamulla (47.2mm) picked up its best rain in three years. Another rain gauge south of Cunnamulla collected 56mm, its heaviest rain in five years.
Elsewhere, Thargomindah (11mm) and Bourke (24) both had their best rain in five months during the 24 hours to 9am on Tuesday.
Weatherzone says showers and storms will spread over central inland Queensland today as the trough moves further north and east. Severe storms are likely once again, with heavy rain causing areas of flash flooding.
Showers and storms should become more confined to eastern districts of Queensland from tomorrow, with drier weather returning to Australia's eastern inland.
