Just 0.4mm here today, with a brief shower. I watched the storms develop overhead this afternoon, only to start dropping rain just to our east as they headed across to Melbourne. Shame they couldn’t have formed just a little further west! It was always going to be a hit and miss scenario though. Lots of rain further west currently, but it appears to be weakening now and struggling to move much further east. This should change as the trough starts moving over the next 24 hours, but I suspect that timing will be crucial for the amount of rainfall depending on how much solar heating occurs before the trough passes through, plus some fairly significant rainfall gradients as we have already seen.
A very humid 25c here today before the wind change. Currently 17c with a DP of 15.2c. There was quite a strong northerly wind this morning, followed by a breezy southeasterly this afternoon, but dead calm right now. Despite the lack of rain here, the sky has been amazing to watch - very tropical looking.
Trough has been clinging to the west for the last couple of days unfortunately, then wizzes past tomorrow, meaning that timing will be off. Hopefully it decides to spurn the models and plant itself in central areas so we can make the most of daytime heat.
What an abysmal storm season for SE Melbourne.... waste of La Niña.

La Niña has always been more of a northern NSW, Qld event. We are just lucky to get some remnants of it. 2011 was an outlier

Yep, you nailed in Sean. System starts to get captured by the westerlies as an upper trough that was back in the bight yesterday moves over the surface trough. The associated jet which has caused the rain and and storms to explode this morning, also drags the system away. The trough actually develops a small low to the southeast of Melbourne for Monday with Progs showing a weak wrap around band into southern areas, so a shot for more rain on Monday and Tuesday in southern areas.
Today brings rain and storms, which clear east. Unfortunately for northern parts, the focus is now more south. The window for heavy falls is narrowing, but with high precip water values it will pour down under any cells. We nearly doubled our total this morning in about ten minutes with a peak rainfall rate of 100mm/hr (event now just shy of 12mm here).
Still not a drop here since Thursday 1mm fog fest. Should get a few mm with trough as it passes in the next hour or two (unless it stalls again and becomes gigantic ha ha) then fingers crossed for accumulations in a SE airflow over next day or so. Still very light NNE wind here, its SSE in Trentham.
Finally scored something decent, just catching the edge of last night's system, plus a direct hit from this morning's band to give us 25mm to 9am; 27mm for the event.
I'll call that a pass . Anything from here on is a bonus.
Had a bit of Thunder between 7.30pm and 8pm last night but just a few not very loud rumbles.
Good news that steady rain followed and a bit more early this morning.
18.5mm's at my place (Sebastopol) but much heavier at Ballarat Airport about 10 kms to my NNW.
They had 40.6mm's up to 9am which means they have already exceeded the Monthly average of 39.7mm's.
Unfortunately the trough has moved East of here so not much more rain for me I think.
Still not a bad start to 2021.
A fair amount of thunder and lightning this morning. Dropped 17mm here but has now cleared and the sun is out. Still hearing the odd distant rumble as it heads east, but unfortunately, the band is also becoming patchier according to the latest radar. In the end, the positioning of the trough wasn't quite in our favour for the kind of falls that were projected even a few days ago, but the weather ultimately does its own thing!
Currently a westerly breeze and 16c. Looks like the low is already forming.

I'm struggling to get my head around this. Yesterday afternoon's forecast chart had the trough not reaching central til 10pm:
Yet the actual 5am chart today has it already out to the east. Does anyone know if the trough line is swinging back and forth (seems unlikely) or was yesterday's forecast chart way off?
Latest radar rotation does seem to suggest a low forming east of Cape Otway?
