Thunderstorms on Tuesday should be less widespread before more settled weather returns to the north on Wednesday. On Tuesday, the trough will move east through NSW and QLD, continuing to bring showers and thunderstorms, this time for northern NSW, and inland southern QLD. Storms could generate damaging-to-destructive wind gusts, large hail and torrential rain leading to flash flooding. There is a decent chance that we will see some severe storms within this outbreak as well, particularly on Monday, as the front and trough move through VIC, NSW and QLD. Large parts of eastern NT, southwest Queensland, western and southern NSW, northern VIC, and northern TAS look likely to see 15-40mm of rain on Monday, with some areas in line for 50-80mm.
