It's interesting, there is a general consensus on the Weatherzone Forums that Higgins tends to over hype such events, and that the latest model runs don't support the Higgins scenario.
A couple of days ago, John's Weather Channel on FB posted the following commentary.
There are reports of a "Large Winter Storm" for south eastern Australia possibly coming next week in some circles.. Let's just say there is a HECK of a lot to play out if this does occur.
WHAT WE KNOW??
- A cold front is likely to surge up from the Great Australia Bight and possibly cut off into a low somewhere from South Australia or all the way out in the Tasman sea Monday/Tuesday June 5th/6th.
- The system is likely to move slowly north then east into the Tasman sea
- The system is expected to be large/broad but unfortunately tropical moisture will be limited with this system so we ARE NOT expecting widespread rainfall across south eastern and eastern Australia, rainfall will be patchy at best but with cold air cold air thunderstorms and hail is possible but will also be patchy.
WHAT IS UNCERTAIN?
- Where the low and front cut off and direction it takes will determine where and if any snow falls so the alps in Vic and NSW could see 30-50cms but it can easily see 0-10cms especially if the low develops over SA and peaks over SA as the airmass will warm once it approaches the alpine regions or if the front and low is weak and peaks well out in the Tasman sea.
- The intensity of the low
Yes there is a front and low that will come through next week somewhere over southern or south eastern Australia but trying to guess snowfalls if any falls at all is ridiculous this far out as 5-6 scenarios can still pan out.. Where it cuts off, how strong the system will be, what region the low heads will determine who gets what type of weather! There is still some chance (lower one) that the low may not even occur at all.
As you can see models are spitting out different scenarios and location of where this low will peak so where it peaks is where the worst of the weather will be/coldest weather. They all agree the low will develop and cut off but no agreement whatsoever of where it goes and peaks.
I think it is a sign of advancing age that I am getting more interested in weather and weather forecasting!
