As two tropical cyclone warnings are issued up north – Tropical Cyclone Magda and now ex-tropical cyclone Neville – in contrast heat waves and scorching the south of the continent – Sydney’s west experiencing 3 consecutive days of 40C or higher temperatures. Lucky the recent rains have made the forests and fields green again that bushfires are not a major threat.
And then of course snow fell during a brief cold snap that passed over southern Australia namely Victoria and southern NSW producing snow over the highlands of the Snowy Mountains. What a month. Now back to the 40C heat!
Incidently, following the two severe storm events prior to Christmas including the Singleton hailstorm, early January was an active period for severe thunderstorms with a few explosive thunderstorm events intercepted.

Storms have been ongoing throughout Victoria over the past couple of days spreading into NSW. Some interesting pulse cells developed with some impressive anvil shields due to deep convection. Temperatures in the upper levels at anvil level have been rather cooler than I have seen it for many years. So the lapse rates in the upper portion of the atmosphere have allowed for some rapid development including the odd overshoot on pulse cells even. This has also enhanced the conditions for hail development once storms can tap into the upper atmosphere. Mid level temperatures have also been rather cool warming up yesterday as the ridge strengthened. We’ll see what happens over the next several days. At least moisture is no issue from now on. Sydney and the North Coast should be in the firing line over the coming days.

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.
