Did Perths rainfall measurement location change after 2016... the May average dropped from 118mm to 88mm . On the Watercorporation site it has two sets of figures one 1876 to 2016. The new ones the averages are all lower.

One from 1994 has much lower averages.

Maybe I've been reading it wrong thought the pre 94 ones were used still wondering why May never seems to get much over 100mm anymore.

Something like that, seems like the old station was shut down in 1992. Take the article title with a grain of salt, just the first thing I found o_O

Temps are about 20°C too high. Never been tempted to live there. Never will be. Already made enough mistakes with my choice of home location.

Anyone know what is causing this bizarre (I assume) artifact (I assume) on the Port Hedland radar? It changes intensity frame to frame but has consistently been there at least for the last 30 mins. Not a WA local... is it always there and I just noticed it?

Thanks for your thoughts everyone. I had also wondered about aircraft, and particularly liked the gas rig being moved theory.

Should the GFS verify in the timestamp.On paper looks a bitterly cold amon over the lower southwest in week4. Likely
there will be some strong gradient wind gusts with it.
In a nutshell its showing a cutoff polar system.

As said above has to verify so worth maybe watching for a trend on future anom modeling.

Dryer winter than last .
Very much so, and warm. No snow events for Bluff Knoll yet. Last year was very wet though, July was off the chart.

July at least looks to be pushing towards the average in the next week or two, and the system on Saturday looks like the coldest of the year so far.

interesting the Perth has more rain in the forecast than Albany

Not really. Stronger north to south frontal bands with the slight orographic lift favour the lower west coast, including the metro area. Particularly earlier in winter with the extra tropical infeed. Usual scarp locations will have the highest totals.

The weak west to east sliders favour the south west Capes. Bight peakers & SW spinners favour the south coast.

How's the peak winter system rearing it’s head South of WA's South West next weekend.
EC progging a 960 central P low. undoubtably the biggest system of the year for that neck of the woods.

A decent system would be nice.

Barely raised a pulse this winter.

Quite a boisterous day, dealing with lots of tree damage, first call out two very large marri fallen across neighbours property - beautiful big healthy trees, fell few hours apart, first one popped the sea container & front corner of house, sea container prevented more damage to house, second one split the large shed & clan lab....

Just a bit of swell about too.

Perth most of the time
I'm pleased to report my trampoline survived

Though Monday night ... Alarm went off at 2am waking whoel house up, turns out door in my home office was slightly ajar and wind got it. It only opened a few mm but enough to trip the reed switch. That coupled with an RCD popping an hour earlier (no power except for lighting) made for a confusing scramble to work out what was going on bleary eyed. Never worked out why the RDC went, presumably some water got into an outdoor powerpoint.

One of the coldest systems in recent years is inbound on the SW next Monday Night/Tuesday.
Snow possible above 600m IMO.

Pea-size hail for Perth is def in the forecast if you ask me.

Should struggle to stay in double digits for much of the SW. This is a very cold system indeed and should break some records IMO.
Places like Mount Dale, Mount Wells, Mount Cooke won't be far off a sleety mix early Tuesday AM.
It's not really a 'Bluff Knoll system' but of course there will be snow up top Tuesday.

they recorded snow in kalamunda in 1957.

The pointer on that map (showing 0.4cm new snow) seems closer to pickering brook than mt cooke
These plots are not that specific. I have zoomed right in there on the map (generally not designed for this sort of fine-sourcing) but instead indicate a general area. Remembering there’s only a handful of mounts over 450-500m on the Darling Scarp - which IMO are the highest chance at observable snowfall.

More-likely, given vertical distance between freeze level and highest terrain (~700m) these locations would more than likely see a sago-type solid than a variety of snow flake, as such.
Fascinating nevertheless.
