still looks a few days into September to me!
Bit of a system coming through around the 2nd/3rd but its the second week when things should really start ramping up as the lower pressures start dominating across the country.
Good to see more and more likely a weak la nina for spring/summer as well.

Looks to be a bit of high based storm action out west tomorrow and Friday, moving east gradually over central areas from Friday night through Saturday.
Looks actually quite promising for us Saturday night.

In terms of rainfall, Sunday-Monday looking pretty wet. A good start to September, which is looking pretty wet now to me.

A few very distant, low long rumbles and a lot of yellow/orange hitting the West Burbs with a heavy shower moving through very quickly. One or 2 similar behind this one and then clearing from the looks of the radar.
Appetiser for the main course tomorrow night I hope.

Seems no one is totally sure - thunder the most likely explanation.
I'd go bolide but 2 claps several minutes apart sort of rules that out.

It was definitely thunder, I was awake and saw the flash, it was what's called "Intracloud" lightning which is basically lightning that stays within the cloud and can spread over a long distance thus creating long lasting thunder. Added to this the storm was very high based and the atmosphere at the time was very still with little wind in the lower regions allowing the thunder to amplify across a wide area.

The image below shows the two simultaneous positive strikes, the beginning and end of the Intracloud lightning.

I was up and about between 2am, and 2.30am and I am pretty sure that the "earthquake[s]" thunder. I heard the reported couple and be interested if anyone heard others, because there was an earlier one too but not a shaker, just noise.
I heard the first window rattler and outside saw the second flash, counted over 45, as one does wink and the second window rattler followed, maybe 15 or 20 seconds later, so a long time, so a long way away from here. I was watching the radar and a lot of yellows and orange visible and heading this way.
In the past, here on the coast, I recall that the army used to used live rounds test fired outside Pt Wakefield and the sound would travel to here. So, if they are sure it was not quake, then the second explanation of thunder makes perfect sense to me.
4.5ml in the gauge this am.

There were still a few bolts in the wee hours up this way and yeah I can see why people could mistake the thunder for tremors.
Back to winter for now. I wouldn't mind so much if we could just get a dusting of snow just for interests sake.
Happy birthday Barb (red earth). Hope the weather hasn't interfered with any of your boat racing activities. smile
Happy Fathers Day to all the Dads out there smile
