December heat wave and bushfire weather return

Tuesday, December 8th, 2009

Bushfires and extreme heat have surprisingly returned. It certainly amazes me how low temperatures over western Queensland a week ago and also parts of the Northern Territory have once again allowed for the heat trough and ridge to set in extending to coastal NSW once again. Furthmore, the wet season has barely made any impact on the Northern Territory or over most parts of northern Australia for that matter! The latest models consistently show extreme heat covering at least a quarter of the continent over  the interior. Basically, this excessive heat must give way to an extensive monsoonal trough and ample rainfall as well as an extensive tropical cyclone season.

Significant rain event NSW Qld 26th October 2009

Monday, October 26th, 2009

Storms and rain look to become widespread throughout the day after some localised heavy rainfall in suburbs of Sydney. Most of the activity seem to be centred on central eastern Queensland which hopefully should extinguish some of those bushfires.

The isolated severe storm that affected Coffs Harbour and Sawtell this morning seem to have been mostly heavy rainfall.

Warm thundery weather 22nd October Bushfires NSW Qld

Wednesday, October 21st, 2009

It seems there is a hint of thunderstorms beginning to be in the picture from the 22nd October over eastern NSW and lingering for some time. Obviously this depends on moisture availability. GFS has been very unreliable with predictions of moisture particularly inland around the Central West this season as with other seasons. The coastal areas are struggling with moisture but nowhere near as serious. This means Sydney and further north to the mid-north coast are in for a chance of storms over the coming days.

Meanwhile, bushfires continue to threaten communities over northern NSW and Queensland. I am certainly surprised to see Rockhampton during October getting serious fire behaviour. Personally, I have yet to see bushfires mentioned in the news so far north into the tropics. At least though the dust storms have eased for the time being.
