Quite like the latest batch of progs. 25-75mm central. Looks like about 50mm here. That’s more than I’ve had in ages. Not a drought breaker, but will set up for a good May. Could be more, but the low bombs a little too east for here. Big totals in Gippsland. Would be surprised if we don’t see at least some warnings out there by Saturday.

Given that Melbourne’s daily May record is just 50mm, history tells us if the models go over this that you’re picking a really extreme scenario in the model space (which probably won’t happen). Sure we’ve got the tend and our weather is getting increasingly erratic, but I still back history to a degree ;)

Nice totals already adding up out west. Thinking about 20mm here overnight.

Hearing some absolutely marvellous sounds on the roof right now! RAIN! :) This first frontal system should provide us with up to 10mm hopefully (going by ACCESS), if we're lucky, 15mm would be grouse! GFS indicates this, though EC is a bit less.

Still love to watch the models trying to decipher this complex system. The 00z EC run certainly wants to give the southwest coast a nice soaking with accumulated falls up to 50-70mm by Friday night. The real focus on EC though is across the eastern ranges, Gippsland and the far east, with widespread totals up to 100mm with higher local falls to 130-150mm.

06z GFS is a lot laid back for the southwest, falls between 20-40mm up to Friday night with spot falls in the Otway region up to 50mm. GFS definitely gives Melbourne (mainly eastern and southeast suburbs) a real blast with falls up to 50-60mm by Friday night with the west side of town generally between 25-30mm. The focus again out east with very high falls between 100-200mm for the far east and locally higher totals above that as we persist into Saturday night.

00z ACCESS-G shows totals along the southwest coast to be around the 15-25mm up to Friday night, while 30-50mm in and around the Melbourne area. And then the focus is all about the east with falls up to 100mm and spot falls to 150mm by Saturday night.

The Canadian model tends to hang falls a bit further west, similar to 06z ACCESS-R, which Jasmine posted earlier this evening, and 06z GFS.

It's still one compliacted system. Worth paying close attention to the models and particularly the observations from this point on. Satellite will become a very handy feature this week! :)

Great to be talking about a proper rain event - at last! Really enjoyed catching up on all the analyses. Looks to me like we won’t do anywhere near as well as eastern parts, given the likely placement of the system, but having any reasonable falls of rain is a good thing during this otherwise long dry spell. Nice band of rain coming through now, and it will be interesting to watch the formation of the low and exactly where it travels. Looks like Gippsland and the eastern ranges will be doing very well out of this!

And the first of the cool changes has arrived. Time to get out the winter blankets, stoke up the fire, find a loved one and a bottle of whiskey.

6mm with round 1. Coldest air is just starting to arrive in SW Vic.

I'm thinking that'll be about it for us, apart from the odd shower of rain in the unstable airmass.

15mm overnight here and left home to 3.8C with a "feels-like" temperature of 1C :D

Thinking we should see some hail, graupel and perhaps even a sleety flurry later today about the tops of the Dandenongs, as the cold air wraps in. Wrap around for tomorrow, but clearing out east by evening.

Probably on target for 40mm for the event here now.

Progs look pretty similar - perhaps a touch better for central on the update.

EDIT> Looks like about 5cm of snow at the more southerly ski resorts.

9.8mm in the AWS, also have not ventured out to check the manual gauges (afternoon visit to nursing home today so a lay-in) but seeing the Melbourne Water Rowville site is showing 9.2mm think all is ok.

10mm on the dot here and a very wintery 2.5C.

Vic snow cams looking impressive already.

11mm last night.

As is typical, the otways are killing off the showers coming into the metro area.

If it goes more southerly, then we will get some

I'm in Melb today and my work colleagues are asking me "Where's the rain and wind the Bureau are in a panic about? It's calm and sunny outside."

I just tell them - "Wait 'til this afternoon".

Beautiful drop of rain overnight to give those gardens a desperately needed drink. Not sure on exact total for my neck of the woods as I didn't have time to check the gauge.

It was certainly nice & chilly out there when I was walking the dog earlier. That Sat Pic looks amazing.
