Thread needed for this lot, first front due today and quite a strong one although doesn't have the penetration but powerful dynamics on it, nice mid level jet wrapping over the top, bit of cold air behind and a tight little low, be quite nasty winds wrapping around the back and across the top for later so certainly will get quite windy later, especially with any showers or possible isolated thunderstorms. Band of storms on the front atm, most of that probably slides but at least still solid showers for us from it plus a few more from cold air behind.

Things moderate off a bit before a second front comes in very early wednesday morning re-invigorating the showers on a blustery WSW flow. A third and much more substantial cold front is due thursday afternoon and evening with a blast of showers and stronger winds, one to watch closely with also the chance of small hail and cold air thunder overnight and into friday as colder air aloft moves in behind and the flow goes more SW.

On friday a 4th front or more a shortwave trough moves in and a new cold pool pushes in more directly from the SW/SSW with lower thicknesses and a higher chance of small hail. Incredibly according to EC at least a 5th trough/front wraps up from around the back of a broad low further SE and flings up a final spate of showers with renewed cold air aloft for another burst of showers during saturday.

See how that all unfolds but looks like a very good rainfall producer for the coasts and especially the hills where we will easily see 100mm+ for the event in wet spots like Uraidla, Stirling, Lenswood etc. Good chance of 30-50mm as it is for parts of the Adelaide area in that period, dropping right off as we go inland. Once the flow goes more SW, Mid North and Mallee areas will have a greater chance of getting some showers, initially they won't do well due to the westerly nature.

TS cool

The first front loomed darkly to the west about an hour ago, it came over, was about 300 meters wide, dropped about half a mm of rain, now cool, windy, clear and sunny.... hope it gets better as the week progresses, and maybe the fronts get stronger.....?

Thanks for the as usual succinct prog Thunderstruck & good to see you back along with the other older wiser heads. Good to see a little more of the wet stuff as Tec accurately forecast for the last system a small amount for Adelaide with most in a narrow band on the East side of the hills. 3ml here then. So pretty dry.

Quite a nice band of thunderstorms riding the front in the states South East, few rumbles here at home and a quickfire 2mm, 12 second RainRate peaked to 78.4mm/hr.

Expecting a few more showers overnight and into Tuesday, Thursday still looking quite wet as the stronger front moves in so will be plenty of wet stuff to come.

Neptune Island leading the way as with the strongest wind gust, so far at 117km/h.

Good to have 'proper' winter weather make an appearance.

Hopefully as the fronts roll through, people's rainfall totals steadily build up.

Speaking of wind, recorded a gust of 41.8 km/h here in Gulfview Heights at 1:38 am this morning.

This has been the best behaved system in a while. Held off all afternoon yesterday so I could watch the footy with my daughter (Bays lost :(, ah well) but then has kicked into gear since. Woke to steady rain and the sound of the tanks overflow pipe running. Good stuff.

4.0mm until 730am. This is the second best daily rainfall for the year to date.

You know things aren't good when the highest daily rainfall so far into the year is 5.0mm (4/4/18)

Yesterday morning, there were some showers out at Peake between 7 & 10am, then bright sunshine and blowing dust in two locations between Peake & Tailem Bend. Threatening looking cloud band came in once we left Mannum, but only a little rain once we got somewhere between Woodside & Crafers.
