CENTRAL, Western and Southeast districts of QLD received more heavy rain with storms yesterday.
Baralaba in the Capricornia picked up a hefty 123mm in the 24 hours to 9am, this is their heaviest daily rain total in 8 years for any month.
Rain rates were also up to 11mm in ten minutes at Longreach and 9mm in ten minutes at Roma.
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 also largely attributable to the very high amounts of moisture in the atmosphere. This is a result of the passing of two ex-Tropical Cyclones, moist southeasterly winds and a prolonged increased flow of moisture from across the Pacific due to the La Nina Event that we are currently experiencing.
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.
