Rain looms for Lower Murray-DarlingBen Domensino, Wednesday April 19, 2017 - 15:07 EST
Parts of the Lower Murray-Darling Basin could receive a month's worth of rain during the next two days.
A low pressure trough tapping into a feed of tropical moisture will generate widespread rain and isolated thunderstorms in Australia's southeast inland on Thursday and Friday.
Widespread falls of 10-20mm are likely over the eastern inland of South Australia, southwest New South Wales and northwest Victoria, with isolated falls in excess of 30mm.
Places like Mildura, Renmark and Pooncarie, which typically receive 15-20mm of rain during the month of April, could see close to this much within just 24 hours. This should be the heaviest rain in at least two months for this region.
Showers will ease and become less widespread as the trough moves further east and weakens on Saturday and Sunday.
A noteworthy feature ahead of the approaching trough has been late-season warmth. Today was the warmest day this late in the April for 118 years at South Australia's Port Lincoln (34C) and 20 years at Hunters Hill (21.5C) in Victoria.
Temperatures will return closer to the seasonal average for the end of the week.
