I hope it does go wet in June. Currently BOM are saying that lower pressures over the Tasman sea are disrupting the westerly cold fronts. That's pretty much what we have seen to date. The high gets held back over SE Australia because every front cuts off in the Tasman. It needs to change for us to get more weather, particularly north of the ranges.

Stratospheric warming occurring in the lower levels near the tropopause over Antarctica in a weeks time on the GEFS ensemble. EC ensemble going for a big cold shot towards Vic after it mixes down sending the tropospheric polar vortex equatorward. Possibly Rossby wave thrust into SE OZ around July 10 to 18th. Signs of a powerful polar surge near 2nd week to mid July if it verifies

Large mid level stratospheric anomaly, 2m temps have risen 4 degrees in Antarctica and SAM is going negative big time. The gates of the south pole are about to open up

EC now starting to model sea level snow in Victoria within 10 days. Still a long way out but the tropospheric polar vortex is weakening and surface temps in Antarctica have now moved upward of 5c within 3 weeks. This looks like a significant cold snap on the cards within 2 weeks IMO.

EC has produced this a couple of times now..... a significant cold core extratropical cyclone near the S.A border. Haven't seen anything like this since the end of September 2016, which spawned tornadoes and knocked out S.A's power. It has a sting jet set up!! Still early days....plenty of downgrades to come I would assume but pure model entertainment
