A total of 4mm over the past 3 days. Now 7mm for the month. Normal rainfall for June is 42mm. Looks like yet another bone dry month. Temps also above normal now for June 2019. Some troughs ahead so we will see how we end up at the end of the month regarding the temps.

Only 2 nights so far this year with below freezing temps. Warmer and drier year after year..

There's no precise criteria for ECL's in terms of numbers but the typical things they have in common include formation close to the coastline due to a steep temp gradient between the (comparatively) warm seas and colder land especially overnight around late autumn/winter, a pre-existing surface trough, midlevel cold air/upper trough passing over the area, and a tropopause fold or undulation accompanying an upstream warm core anomaly at about the 200hpa height which induces warm air advection below it.
You could argue that the current system forming off the NSW coast has many of these elements but unlike your textbook ECL, this system is likely to move fairly quickly further out into the Tasman Sea before it gets a chance to intensify significantly (classic ECL's tend to hug and stay close to the coastline for awhile during this intensification process).
And a complex low is just an area of low pressure with multiple centres inside it.
There's info about the various types of systems that affect Australia here: http://www.bom.gov.au/climate/about/?bookmark=eastcoastlow

EC currently trying to form a low over waters off the southern or southern-central QLD coast early to mid next week with a strong onshore flow developing to its south but I won't bother looking into the finer details for another few days unless it holds.

Fairly big variations in the observed rainfall amounts/distributions yesterday as you'd expect with convective precip - see above. Sunshine Coast did well as usual.

Brisbane's received 30.8mm of rainfall so far this month which is about 60% of our median June rainfall, and 5 rain days which is about half of the average number of rain days in June. So could be worse.

You guys down there are lucky, we've had 90 percent humidity yesterday blue sky and no clouds, humidity without any rain in Yeppoon.

What's the chance of Brisbane forecast temp reaching 24C today? Just has that feel of a mild winter's day with the SWs, low DPs and bright sky light levels. 22.5C now. 25C forecast tomorrow.

I recorded 87mm from last night's storm.

After watching the first part of it wrapped around to the south of us then push straight east as it came off the ranges I called it another miss for us. But glad to say I was wrong and the rain started about 6pm, there was some good gusts in it and the lightening was still going strong after midnight.

I note Ewen Maddock recorded 109mm for the 24hrs, obviously the leading edge that missed us went through that area.

Ended up with 34.0mm here for the last 24 hours which is the best winter rainfall in a few years.

Is anyone else having trouble with LightningMaps.org?
Their sister site, Blitzortung.org, is working fine.

I noticed there was a problem yesterday when there was an almighty crack of thunder around 2:30pm.
The only recorded strike at that time was marked in the dam near the corner of Samford Rd and Upper Kedron Rd (give or take a km.)

I see this occasionally: overflying aircraft <30000'. Thai Airways 787 enroute Akl to Bkk at 28000' 439kt - must doing everything it can to avoid pretty hefty STJ ripping SE across Qld.

Yeah the STJ is a big factor in optimal cruising altitudes for best cost index as well as things like the associated clear air turbulence near the height of the jetstream, and the fact that lower cruising altitudes are often chosen for the early stages of longer routes because aircraft are heavy with fuel... then climb to progressively higher altitudes later on in the flight.

Models still differing on how the evolve the possible elongated area of low pressure with multiple embedded centres off eastern Australia early next week in response to the upper trough and pretty cold air aloft (which may also cool daytime max temps).

Some like EC currently form it over the southern or southwestern Coral Sea with one of the centres close to the coast while some like FVS-GFS have it over the northern or northeastern Tasman Sea.
The dream scenario for us of course is if it formed just to our north near the coast giving us a strong moist onshore flow with heavy rain aided by the upper support.
If it forms further out to sea, we'd have to rely more on the upper trough/low for the rainfall.
Either way, it looks like winds may increase near the coast if there's enough pressure gradient squeeze.

Thanks for your input Ken. Three days of good falls predicted from Sunday for Sunny Coast not that we need it after the cracking storm last Sunday.

Anybody lucky enough to be out on the water today taking advantage of this still weather? Not a day for sailing I would imagine. The few scattered fair weather cumulus over Brisbane are just being nudged along by the southerly.
