    Some decent totals are building up, but once again the bigs falls cling to the coast:



    It's raining again after a short break. There's been 11 mm in the City, 10 mm at Chatswood since 9:00. The biggest falls have been on the Central Coast, with 33 mm at Gosford. Bellambi is on 26 m.

    As it was. Thanks.
    I woke this morning at 6 am, saw the radar pics, and panicked a little. Rang concrete supplier and pump operator.
    Managed to bring the concrete pour forward by 2 hours to 8.30 am, instead of 10.30 am.
    Finished the pour by 10 am. Rain started at 10.45.
    Thanks Huey. Good job.

    There have been periods of very steady rain here on and off since then, and it has remained cold by Sydney standards at this time of year, hovering around 11-12 degrees since lunchtime. Currently 10.9 deg's and rain is consistent. A beautiful afternoon after so much dry. Lovely soaking rain that actually slowly penetrates the soil.

    Rain shield over Bowral in effect, and sad to go from 120mm a few days ago to just 1 to 4 mm tomorrow. sigh

    Looks like more trains inbound
    I've had 52.
    Just a bit closer to the escarpment than the ridiculous Bellambi placement of the AWS

    Well, today what was what most Australians think of as "Wintry". Solid overcast, no sign of the sun or blue sky, raining most of the day with the temperature spiking to 14.7° at OH before 9:00 just before the rain started in earnest. Falls have been heaviest on the coast but totals of 10+ mm have penetrated into Sydney's Western suburbs. There has been 24 mm at Chatswood.

    Sydney's forecast total for tomorrow is 20-60 mm before it clears and warms for the start of Spring.

    Looking forward to the forecast 28° in a week's time.

    See this is why I don't buy the Drier part of the forecast by the BOM for the seasonal, above average is basically locked in. Although the heat troughs that can dip in like that being modeled by EC can definitely shift our odds for rainfall, along with the SSW event, very unsure what can happen.

    I would be really annoyed if the Upper Nepean catchment doesn't see huge inflows with this. Hopefully the Warragamba catchs a good drinking.

    It’s pushing in a reasonable way on radar so hopefully we get some inflows after it’s finished soaking the ground first

    I put the kiss of death on this. Hardly anything else fell.

    Rain looks to be shifting north earlier than expected

    Here's the rainfall in NSW since 9:00 yesterday, with the 24 hours nearly up.


    So some decent falls (25+ mm) along the coast from the Lake Macquarie area to South of Jervis Bay, with a focus on Northern Sydney and the Central Coast. Falls of 10+ mm penetrate into the Upper Blue Mountains with light falls in the Central West. There's another cluster of falls around Coffs Harbour.

    It's still raining lightly here. Chatswood picked up 57 mm to 8:00 AM.

    Re temperatres, Sydney's maximum for yesterday will be close to14.4 (9:00 yesterday), making it only the 4th sub-15 maximum and second lowest maximum this year. The coldest was 14.1 on June 4 and the other two were June 7 & 8.

    75mm at Bellambi, what a great result!! I'm so stocked that we got a lot here, we certainly needed it. Albion Park much less at 33mm but still a good drop. I would have been somewhere in between, perhaps 40-50mm. For once I'm glad I forecasted wrong. Now for a week of dry and warmish weather to get that spring growth happening. Some brilliant days coming up that can be enjoyed knowing that we've had good rain.

    On another note, -12.0°C at Perisher AWS this morning [​IMG]

    Very steady rain here all morning which has become heavier over the past hour or so.
    Still cold as well at just 11.4 deg's.

    150mm now for Gosford since 9am yesterday and still a bit to come.

    Sydney 56mm over the same period. A few areas in the metro would be above 100mm. Wahroonga is bang on 100mm (72mm + 28mm since 9am so far today). St Ives also had 92mm to 9am today with no data since, so is almost certainly above 100mm now too.

    Light, steady rain continues, without a break since I got up this morning around 7:00 as far as I can tell. Chatswood is up to 20 mm since 9:00AM to add to the 59mm it received in the prior 24 hours. The rain band is showing no signs of shifting.

    I had a drive to Lane Cove National Park late this morning. The weir was overflowing for the first time in a while and Riverside Falls have jumped back into life:

    Its been really nice!!! No localised flooding as we've had no rain forever......... Ovals only having standing water as of this arvo. Rain penetrating well into our catchment, very much needed. All local sport off tomorrow except netball at this point, can only hope its on so it doesn't delay a ski trip if netball is postponed until Sunday.

    It's a cool to mild and overcast morning, with a couple of (small) patches of blue sky. There's been a bit of rain overnight but I think that the main event has finished here. Showers continue on the Central Coast and Newcastle area.

    There have been some big totals since 9:00 yesterday, mostly 50+ mm on the Central Coast and Newcastle area, with a few falls over 100 mm in the Central Coast hinterland. Good to see rain finally penetrating into the lower Hunter at least, with falls around 40 mm at Maitland and Cessnock.

    North of the Harbour, Sydney got 20+ mm. There was little or nothing in Sydney's South or West.
    Chatswood has received 34 mm since 9:00 yesterday, giving a total of 93 mm since 9:00 Friday and 109 mm since Monday.

    Wahroonga ended up with 55mm yesterday and St Ives 56mm, for two-day totals of 127mm and 148mm respectively. These are likely to be high points for the Sydney basin unless there's a gauge that I can't see on the map (like Turramurra) that has bettered them.

    Gosford nearly cracked the 200mm mark over the same period and has received a few mm today after 9am to take the event total beyond 200mm

    Yep. You are pretty much right with your totals.
    It's been a surprisingly fruitful event rainfall wise for those in the sweet spot - those being the northern half of the metro, the Central Coast and Newcastle.
    Good to see that Stormy got a decent total, even though it was portrayed as a negative.
    This event was ultimately better than predicted for certain areas. We can't complain about that.

    The best thing was that for certain areas, it was just slow, continuous steady rain, over a sustained period of time, which was perfect for soil penetration. I've had about 70 mm's, which was delivered over roughly a 48 hour period. Nice, steady showers/rain.

    All of you guys have done extremely well for rainfall I picked up a reasonable 31.2mm nothing to write home about, but as good as it gets in the driest period of the year. I'll take what i can get, a rocky period upcoming, though with the SSW.

    I though that I might write a quick wrap-up of this event, which has now definitely finished. Please feel free to add to the list.

    Rainfall: totals at selected sites (mm), 9:00 August 26 to September 1:
    • Newcastle...: 102
    • Gosford.....: 220
    • Chatswood...: 110
    • Sydney......: .70
    • Parramatta..: .54
    • Lithgow.....: .13
    • Bellambi....: .88
    • Nowra.......: .35
    Temperatures: some of the colder days this Winter on the coast. Pair of sub-15 days at Sydney OH, the coldest days there in August (only 5 sub-15 days there this year).

    Thundertorms: reports of thunder and lightning near the coast. Major hail at Coffs Harbour.

    Snow: seems to have been none outside Alpine areas and not much there.
