How odd. Melbs is having very cold day, while im having my warmest day of the month at Mt Macedon. Hardly any temp difference between the two despite my 860m elevation.

11s and 10s around central melbourne and a shade above 9C at Mt Macedon.

What gives?

Good old winter day in Melbourne. Could almost imagine I was in London with grey murk and temps which almost justified a winter coast :P First sub-10C in June for a while (unless it rises overnight which isn't out of the question???).

Startling inversion in the Dandenong this morning. Car thermometer went form 7C at our place (560m) to 2C at (150m). It dropped almost all of that over about 100m of vertical. Above the inversion we got to a lofty 9.9C and at one point our DP dropped to -5C. That is quite a stunning inversion. They do happen, but they rarely last all day at such a low elevation.

Maybe some spits overnight???

Max of 8.5 today, down to 4.1 already under clear skies with mist hovering. Was some spits of rain earlier. City is on 8.3 degrees.

Also, Melbourne city's maximum of 9.8 today was the coldest June day in 25 years.

A max of 9.5c here today after a low of 0.1c. Must have been just above the inversion here as well, as we’re typically a few degrees colder than Melbourne at this time of year. We’ve had a lot of mist and smoke around these parts over the past few days with a complete absence of wind, and I assume a lot of people burning off.

An impressive maximum spoilt by rising temperatures through the night :( Current max sat on 10.3C. By some irony as the winds mixed the Dandenongs have got colder and the low levels have got warmer (not surprised as you've mixed warm air down and cold air up).

I look at the charts and it's just hopeless. The kind of frustration we felt during the millennium drought. BOM's long-range forecast is dim reading too.

While the Indian ocean has warmed up a fair bit recently - that cold upwelling has ceased. The cut off lows in the Tasman continue which hold the high back over us in a narrow ridge that the good strong WA fronts keep slamming into. If a front is strong enough to get through - about once every 2 weeks, it's upper component induces the next Tasman tea low recreating the block all over again. This pattern just continues and continues.

The weather we have been getting is due to the SAM influences induced by SSM as outlined by Jasmine - without that, it would be dismal indeed.

Of course, one big inland cut off low with tropical infeed could change it all around - these are the saviours in a dry year. GFS recently showed one on the long range but it quickly disappeared. Can only hope...

The Indian Ocean appears to be trending towards +ve IOD at present. Anyway, it looks like a decent cold front around July 6-8 to keep the ski season ticking along. EC reckons around 12mm for us.

Peasouper fog this morning.

I had a feeling that might happen. Happens every time. We just can't get sustained cold weather.

10.6C in the end. June record for Melbourne is 5.3C so puts it in perspective :( I randomly looked at June 100 years ago, 50 years ago, 20 years ago and 10 years ago. They saw 9.9, 9.9, 10.0 and 11.6C. Make what you want of those numbers :P

In a bit of a turnaround after a few really mild days in the Dandenongs for mid winter, yesterday was quite feral. Max of 7C for us with squally winds. Today’s looks similar, but quite a few showers. Latest EC has about 10mm. Unfortunately it’s coming too late to stop June turning in another below average total (about 10mm below our long term average). Got 0.8mm in the gauge for today so far.

Btw week ahead starting to look a bit more interesting. Mild,windy and becoming wet and much colder. Could be a decent rainband on Thursday with a very mild system, then solid cold outbreak for next weekend. Mid week could well bring 20s to the norrthwest and Gippsland :x Time for a new thread?

EDIT: pouring up here now with thick fog. This initial system is actually more of a warm front than cold front with, with the cold air lagging back towards the border. Strong warm air advection with the rain and cloud coming in from the sw while winds are nw.

Daytime temperatures have been close to average this month but nightime temps

Nice wet drive on the way down to the island this morning. Still have some dribbles hanging around.

Meanwhile it's dry as a bone back in the western boredom zone according to the radar. :roll:
