That hail storms range wasnt too wide, i have workmates from the south east who barely got rain, and i just got light rain in the west with thunder. Last Thursday was a better event with way more lightning and rain.

Currently its been raining for nearly 4 hours, its definitely needed. Certain areas have had a lot

Also somewhere near ballarat got 200mm+ last night. There was a storm that was stationary on the radar for hours

Nice drop indeed.

Yesterdays polar trough over SE Australia had a 500mb polar jet stream of 70knots as far north as lattitude 30deg. Quite unseasonal. I wish we could get a trough like that over the North Island in January.

Pretty amazing and rare satellite photo for the continent right now:

That tropical moisture set to get to Adelaide tomorrow with very high dewpoints which is very rare for the desert/Mediterranean type climate there, precipitable water values more akin to the deep tropics - getting as high as 70mm.

Midday tomorrow:

Around 400mm last 4 days in Sydney, pretty impressive totals!

Talk about from one extreme to the other

I saw a crackup social media share earlier of some lad swimming through a McDonalds drivethrough. Only in Oz

For what it's worth, the BoM have majorly upgraded it's ACCESS-G (global domain) model to APS3 version and is now operational after a couple years of testing and refinements.

A bit of info here: http://www.bom.gov.au/nwp/doc/access/NWPData.shtml

Haha here's another one similar to the flooded McD's drive through. https://www.dailymail.co.uk/news/articl ... -back.html

Hasnt dropped below 17 for a week in Melbourne and its humid and looks like it'll stay that way into next week. I'm sick of it feeling like Brisbane with no rain or queensland-like storms. Hopefully we get something this afternoon.

Some great imagery here from the ESA's Sentinel satellites in a piece by the ABC:

According the published BoM data, the OZ rainfall trend is going up. The only area of Australia with an ongoing downward trend over 1mm per decade is the SW corner.

What published data is that?

Because your claim contradicts the BoM charts:

Sorry but not my claim. It's in the BoM data series going back from 2019 to 1900

The regional map is better
Shows that plcaes like NSW that had the bush fires the trend is drier

Cyclone Tracy · Unread post by **Cyclone Tracy** » Wed 19/02/2020 19:34

The regional trend map also shows 95% of NSW and ACT has an increasing rainfall trend over the 119 year data set. 60% of Australia's coastline (Maritime) has a wetter trend on the overall map.

http://www.bom.gov.au/climate/change/in ... iod%3D1900

Graph on numerical data also shows this http://www.bom.gov.au/climate/change/in ... ave_yr%3DT

Anyway, I don't really have an opinion on the subject, I'm just pointing out the BoM published data.

i was meaning this one:
http://www.bom.gov.au/climate/change/in ... iod%3D1980

i.e the last 40 year trend
which shows a drying trend for Martime climate areas

Great to see such widespread rainfall across the southeast!

Thargomindah in southwest Queensland with 128mm to 9am today - the biggest March fall in over 70 years for there.

Here's some great video of the flooding at Thargomindah:

"Meanwhile ... in the drought ravaged Aussie outback ...
We just got word from a neighbouring station. The trucks went in when to pick up cattle when it was dry - then the rains came. The convoy got bogged and the rains continued ...."

I see Australia has cooled down from that early Summer peak of above average temperatures which was related to long term drought + the IOD event which played a major part in the recent extreme bush fire season.

Perth recorded 39.5C today, an April record!

Cyclone Tracy · Unread post by **Cyclone Tracy** » Thu 30/04/2020 20:17

Global met agencies are really starting to lock onto a significant negative Indian Ocean Dipole (IOD). If ECMWF verifies, major flooding across interior, east coast and the SE corner of OZ is on the way, especially in August and September. The Australian climatic cycle from drought to flood is on the cards again.

Awhituobs · Unread post by **Awhituobs** » Thu 30/04/2020 20:31

A warm eastern Indian Ocean should mean a wet spring for western NZ

Another rather lacklustre wet season here in Darwin. 1180mm compared to an 1683mm average at Darwin Airport. A saving grace was good activity around the 9th of March.

We may be facing water restrictions for the first time in many years though this dry season!
