"A strong upper low will move slowly eastward across southeast Queensland today and through Saturday," BoM said.
"A deepening and slow-moving surface trough that extends from Seventeen Seventy down to a developing low pressure system near Biggenden and over the eastern Darling Downs will continue to produce areas of heavy rain with embedded thunderstorms."
