I've been eyeing this one off for about a week now (and this window for a few weeks now), as models are now settling on this system at the end of next week. A weakening front looks set to pass through Victoria/Tas Tuesday night, Wednesday morning, this system will bring snow to Mainland Alps above 1700m. Given the ridging; it's a quick system bringing ~5cm above 2k potentially at this stage. Following this, the trailing ridge broadens and we see a high amplitude polar jet buckle over the SE of the continent, bringing a cold outbreak to NSW, Vic, Tas and even parts of SA. By Friday arvo we see the ridge sit under WA potentially forging a cut off system through the SE with a wandering cold pool through Vic & NSW. FL dropping down to around 1300m, with snow falling above 900m in parts of NSW & Victoria IMO. Places such as Blue Mountains, CT's (and possibly New England Tablelands & Barrington Tops) have a good chance of some snow showers. It's trending towards snow in strange places, especially for May. IMO the mainland alps will see ~10cm (maybe up to 15cm), but the crowd-pleaser will be the incursion of the cold air, with it potentially reaching Northern NSW. Might see some snowguns tested but def nothing sticking around longer than a few days IMO. Beyond this we see the broad ridge settle over Southern Aus which looks to block much else behind it so things look stable beyond next weekend into the forseeable.
