Southern and South East QLD as well as North East NSW are about to endure a frosty week coming up, with consecutive nights well below average likely – Above image – Sunday morning minimum temperatures via BSCH / OCF.
A very large and strong high pressure system is expected to become slow moving and spend the entire week moving across Australia. The system is expected to be so large that its likely to cover the entirety of Australia for the majority of the week. What this will allow for is widespread clear skies across a large portion of the country, but as a focus – South East QLD, Southern QLD, Northern NSW and North East NSW. These clear skies are likely combine with light winds from about Tuesday onwards to provide ideal conditions for frost, with some areas potentially seeing heavy frost over the Granite Belt, Darling Downs and Northern NSW Tablelands where temperatures are likely to be much colder than surrounding areas. During Sunday and Monday, the temperatures will be cold enough, but moderate to gusty winds may prevent frost from settling.
During the next week from Sunday (July 14) through to Saturday (July 20), Glen Innes is looking at virtually every night below -3 or -4ºc with some nights dropping down to as low as -6 or -7ºc. Guyra, Armidale, Tenterfield and Stanthorpe are looking at every night below freezing. Warwick, Inverell, Moree, Dalby, Oakey and Kingaroy are likely to be between 0 and 2ºc every night with some nights below freezing… while closer to the Coast, Ipswich, Gatton, Grafton, Casino, Beaudesert and surrounds will be cold enough for frost most mornings.
Even directly along the Coast, the South West winds should provide enough cooling for Brisbane, Redcliffe, the Sunshine Coast and Gold Coast to be in single digits – which is below average for July.
