We’ve got a very unusual pattern moving through over the next few days. A big upper pool of cold air moving NW to SE, and a resultant East Coast Low:
We’ll see some rain from this, particularly today…but with the low to our south it won’t take long for the drier winds to sweep in from the west. As the low moves away we could see more showers as a brisk southerly sweeps in:
…meanwhile the south coast looks like copping another bashing with up to 300mm and flooding possible – and likely to be some good wet snow dumps up on the mountains as well:
Once this system clears through there is the potential for another to move through – and this one could be further north. This is how the models see it right now – but bear in mind that this is a long way out so we’re likely to see many changes to the details over the coming days:
…move forwards to rain totals at +240 hours and you can see how much rain that system is already likely to bring across NSW:
BIG falls for the inland – great to see. The monthly model outlooks are now available through to the end of the year and they all show ongoing wetter than average conditions across eastern Australia through to January. That doesn’t mean wet all the time – but averaged over time we should see wetter conditions prevail this Spring – very different to last year!
Looking further afield get ready for a very active hurricane period later this month for the USA. Likely quieter over the next 10 days but beyond that it could well explode – something we’ll likely see on the news over the coming month.
