Thanks to the magic of the Bureau of Meteorology's website, you can see there is a high pressure system parked just west of Tasmania, with a low out in the Tasman Sea - and that gives direct northerly winds between both systems. That chart is from two days ago (5 am, 22/10/08)
We here in Robertson have shivered for the last 3 days. By chance (not really) I awoke shivering in my bed. I was really cold. I happened to glance at my handy indoor/outdoor thermometer (in the corner of my bedroom) just to see what was going on. It was showing 3 degrees Celsius outside. It gave me a generous reading of 5 degrees inside. That is to be expected in July, but not mid October. Plus it has been "windy as...." - by then a howling gale had arrived.
The Sydney Morning Herald reported it in this fashion:
"A low pressure system over the Tasman sea had the effect of sucking up frigid air from Australia's south, delivering a record breaking cold snap and even snow to highland areas across NSW.
"Bureau of Meteorology senior forecaster Jake Phillips said it was the coldest two days, back to back, in an October since 1973. With the cold temperatures came blustery winds and intermittent showers."
By one of those ironies of Google-based advertising on Internet websites, the SMH story about Sydney's "Tasmanian-style" weather, they carried this advertisement - right next to the lead paragraph.

An hour later, all I could see was the trees at 50 metres distance - all else had disappeared.
To my beloved fellow Tasmanian Bloggers - if that's your idea of weather - please keep it to yourselves. (Nothing personal Mosura, et al - please forgive a little "literary licence" being exercised. With weather like this - we have to blame somebody.)
