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.

What an incredible sight to awaken to a thick dust storm across Sydneyinfact the whole of NSW, the ACT and Qld. It created a mess right across the Sydney suburbs and also caused disruptions to the airport.

The drought across NSW has deepened and this is a result of a strong upper level system that produced gale force winds with an associated wind shift. The wind shear was sufficient to lift dust which persisted for an extraordinary distance.

A more detailed discussion can be found in the duststorm topic.
