Rainy one day, freezing the next
PARTS of Queensland have shivered through their coldest December morning, breaking half-century-old weather records in the process.
According to the Bureau of Meteorology, the weather system that brought days of severe storms and heavy rainfall to the coastal half of the state has since moved offshore into the Coral Sea.
A cool dry southerly air mass has since moved into much of the west, west tropics and the Central Highlands.
Forecaster David Grant said it was an 'unusual' situation but the strong December sun means the cool change will likely dissipate tomorrow.
Mt Isa had its coldest December day since 1966. At 12C, Mt Isa was 11.1C below average.
Mr Grant said it was 'dramatically cold' in Burketown, which recorded a low of 16.0C. It was only colder in 1907 when the isolated far north-western town logged 15.0C.
The December average minimum temperature for Burketown is 23.1C.
Clermont in the Central Highlands had its coldest day since December 1964 at 12.8C while Blackall recorded 11.8C for its coldest December day since 1974.
It reached 17.8C in Brisbane overnight.
Queensland is officially in a La Nina, the Bureau has confirmed, increasing the chances of an extremely wet, flood-prone summer.
Climate modelling by the Bureau shows the cooling event will be weak and short-lived, lasting until early autumn next year.
This comes as experts warn southeast Queensland homeowners could be thousands of dollars out of pocket unless they deal with weak trees now.
Arborists have said an unusually dry winter followed by large amounts of rain has loosened soil and made trees susceptible to damage.
Arbor Operations' Aaron Nunn said calling out an expert to check on a tree would cost less than $200 but strong wind felling a tree could push the bill to thousands.
"It's often trees that are larger in urban areas, be it private, or council governed land are the trees that cause the most damage because of the installation of the infrastructure," he said.
"It can be anything from a total failure at ground level to limbs being torn,"
"I've seen a number of houses lost to the point they're cut in half, I've seen vehicles turned into pancakes."
According to the NRMA, 1 in 3 Queensland property owners has not taken any measures to prepare their homes for storm season.
Electricity provider Energex attends 800 incidents of vegetation blown onto powerlines during severe weather events annually but warned homeowners against taking tree scaping into their own hands.
"In more severe cases vegetation carried by high winds can be dangerous missiles bringing down powerlines," a spokesman said.
Thunderstorms last night buffeted the Sunshine Coast, forcing the extended suspension of trains and shutting beaches along the coast.
So far this month the Sunshine Coast has copped 143.2mm of rain.
Weather across the southeast Queensland coast is expected to be sunny and warm for the next few days, reaching maximum temperature of about 33C.
