Central, western and southeast QLD received more heavy rain with storms Tuesday. This was generally their heaviest rain since December 2010.

Baralaba in the Capricornia picked up a hefty 123mm in the 24 hours to 9am yesterday, this is their heaviest daily rain total in 8 years.

Injune received 57mm of rain to 9am and Monto picked up 54mm, their highest daily totals since the widespread heavy rain in December of last year.

The storms developed yesterday due to cold upper level air which increased the instability in the atmosphere. There was also a surface low pressure trough moving through southern QLD which was already causing patchy rain and the odd storm.

The heavy rain is largely attributable to the very high amounts of moisture in the atmosphere. This is a result of the passing of ex-Tropical Cyclones and an increased flow of moisture from across the Pacific.

Storm activity will contract further north into the tropics over the next few days thanks to a high pressure ridge strengthening in the east and stabilising the atmosphere.

The heavy rain will move west into the NT today with the movement of the cold upper level air.
