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.

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.

It seems like the indicators such as the Southern Oscillation Index has drought conditions worsening in Victoria and southern NSW. This is absolutely astonishing considering the type of summer Victoria had to contend with. Dry conditions continuing can only increase the likelihood of more potent bush fire weather in these regions.
Here it also continues rather cool and dry though frosts have not been as severe as other years. And it seems that the next couple of days may see increasing temperatures – Adelaide has a forecast temperature of 23C – rather unusual for this time of the year. Will be interesting to see if there is a rapid increase in temperature across central Australia and if this is periodically advected down to the southern parts towards the latter part of winter and early spring.
