It actually did rain in Sydney. I drove from Wollongong to Surry Hills around 9am. Drove through some solid showers from Heathcote right the way to the airport tunnel. Mind you it was pouring on Mt Ousley. Steamy arvo now in Wollongong.
Yes, I should qualify my post to say it didn’t rain where I was yesterday (within a couple of hundred metres of home) while I was awake. There were light showers overnight in Sydney, mostly just a millimetre or two, including a millimetre at Chatswood but none at OH.
There was actually plenty of heavy drizzle in parts of the Hills this morning. Beyond that, I had to drive out to St Mary's and Badgerys's Creek this morning and there was more than a decent amount of showers throughout the drive. Sure, the AWS totals are low, but there was far more precipitation around this morning than what the BOM forecast. . The disappointing thing is that it wasn't really forecast to be as wet as it was. It cost me a days work today. Not the BOM's fault that I lost a days work, but geez, I somewhat expect a bit better accuracy at such short notice - ie - the 4.40 am forecast update.
No rain here in the Northern Beaches at all. In fact this morning was clear and sunny. Then the cloud rolled over at half 12 from the NW and gave us two hours of gloom before breaking up again. Got painters doing the outside of my house this week - no interruptions for them.
Sunday looks like a no sea breeze day at this stage. Even the usual magnets like Bondi and The Entrance are forecast to reach 39C and 41C respectively. The timing of the change may be a factor further south, though even Ulladulla is looking at 36C
Satellite images showing the southerly, by way of a roll cloud of sorts, moving up the NSW south coast.
Definitely not looking forward to this heat. A silver lining has been the extra rain compared to last year. For the October-November period in 2019 at OH there was only 65.2mm of rain. This year there has been 177.4. Last year it was around this time when all of the plants started dying and the creeks ran dry, thankfully there won't be that stress on the environment this year.
The southerly swept through here around 8pm , a lot sooner than I expected and a lot cooler as well. I have opened up the house in a vain attempt to get the house as cool as possible before the weekend's heatwave.
Some quick pic of the southerly moving through port kembla. There was 3 distinct cloud "waves" of which two were shown in this pic. Interestingly, as it moved overhead could clearly see it rotating.
Hot hot hot in Sydney!! Badgerys hit 47.2 but anomalous one would suspect after recent posts. Even the Harbour is 38.9 and seabreeze non existent from Moruya to Williamtown.
@warrie There is a thread for this current heat spell here. https://www.ski.com.au/xf/threads/nsw-act-intense-heatwave-nov-27-to-dec-2.88712/#post-4508419 It is common knowledge atm that Badgery's Creek AWS is over reading temps.
I for one wouldn't be ruling out thunderstorms through the CTs and ACT region this arvo. Bit of instab associated with the weakening front moving through Vic & NSW today.
Pretty big inversion in the Sydney metro area, be ineresting to see if this cloud dissapears to allow for the 40c forecast temps for western sydney
There’s been a blob of low cloud over the central part of the NSW Coast all morning but it’s now rapidly shrinking. The sun should be out soon. EDIT: we have sun and cicadas.
November 2020 Summary Very warm and dry month (almost +3° C on maxes and +2° C on mins), largely due to the solid –AAO dip later in the month; thus overriding the effects of La Nina. Anomalies (BoM Obs) Mean Maximum: 22.7° C (+2.8° C) Mean Minimum: 12.1° C (+2.1° C) Precipitation: 48.8 mm (–44.0 mm)
Chance for storms could popup anywhere along the instability lines this afternoon. 400+ Tornado possible.
In coming on Greater Sydney. Should fall apart on the Sydney Basin however. EDIT: right, I see where the chatter is.
Anyone see the first BOM Bulletin this morning, for Sydney? It’s words read “Chance of showers in the West, near Zero chance of rain elsewhere”, I remember reading over it several times, at around 8am. Disagreeing, in my head, with each read. The forecast was updated at 8:30am. It's now raining here in Bondi.
Yep Big crack of thunder overheard here in Frenchs Forest. Radar looks intersting. May get some nice rain here
Big crack of thunder here. I hadn’t looked at the radar all day and was not even a chance in the forecast. Wtf. Very annoying - about to mow the lawn
trying to study and hearing thunder in balgowlah! little cells on the radar. a bit dark. took me be surprise
had a brief shower in Bondi Junction about an hour ago. Lightning tracker showing a bit sparky off the coast https://map.blitzortung.org/#10.47/-33.8571/151.216
Same here in E burbs. BoM just can’t forecast that sort stuff in a stiff SE’ly. Not in a nina year...
I was surprised to hear thunder while having lunch on what I thought was a stock-standard marine layer day. As nearly always this season, the storm passed to my North, but this time only by a few km. There was a small amount of rain (1 mm at Chatswood) and about 15 minutes of rumbling as the storm quickly passed by. Low cloud blocked any visibility of structure. It’s been mostly 100% overcast since the storm. It’s now cool and quite gloomy, one of those Summer days that feature a dull grey twilight from about 4:00PM to 8:00 PM. Tomorrow looks like a repeat, but without the storm.
Some light rain the basin only picked up 0.5mms, happy to keep the needle ticking though. Interesting 6.2mms picked up at Penrith possibly lift from the escarpment. Honestly i do treasure a gloomy summer day once in a while after some heat, takes some burden off the aircon. I can use the entire day.
24 hours of gloom so far and sat pic shows plenty off the coast.Gloom can last up to 3 days and you acclimatise to it then the heat feels worse next time it hits which is inevitable in Dec
The low level gloom is moving east off the coast and out to sea. The higher level cloud streaming in from the NW is aiding and abetting the persistence of the low level gloom. The winds are more from the NE so normally you would expect a clearing trend by now.
No gloom atm - sunny skies with a gentle breeze at Mascot. OH has already reached its forecast high of 28 (rounded). BOM has forecasted light winds today. Whilst I can generally read wind direction and speed from synoptic charts, I cant usually tell from them how strong the seabreeze will be. I guess heating of the land is not the only factor.
It’s a great improvement on yesterday. Streaming high and mid-level cloud on top of the marine layer made yesterday quite gloomy, lights on during the day and not a glimpse of sky or sun. I hope we don’t get too many days like yesterday this Summer. Today it’s clear skies and sunshine after the last of the marine layer broke up after dawn. An Easterly is now up and running on the coast. The synoptic chart shows no strong circulation, so combined with cool offshore sea temps I would expect the sea breeze to be fairly strong.
