Looks like that squall originated from a storm west of Y.P. dying which sent out a big ofb and surged across y.p. to Adelaide. Caught BoM off guard with a quick warning once that 113km gust came in, was a very interesting and quite localised area of winds. Very high bases around 4km with dry air underneath, classic evaporative cooling driven gust. I wonder how strong the initial gust was over water as it maintained itself damn well over distance.

Wednesday still looking pretty awesome. Focus of upper cold pool in a great spot (and still progged around -29 @ 500mb on approach, very impressive for late November) for central regions and a very solid low just off to the south. Wednesday evening/night is going to be wild. Isolated storms, small hail, local heavy falls and frequent showers with strong to maybe gale force winds depending on low positioning. EC chucked out a rather insane prog with 65kt (120km) gusts on the west coast of Y.P. and GFS seems pretty keen for an angry LLJ too. Winter like impacts and with this low pressure system, high tides (2.45m at outer harbour so rather high before any potential storm surge impact) peaking just after 4am as well, may see some coastal erosion.
Will make a thread tomorrow.

Steady, heavy rain in the CBD, lovely sound.

I wish Mt Lofty was more lofty, another 2km or so would suffice.

Picked up 9mm from the band, and another 3mm from some showers.
12mm so far, happy with that for a head start

from reset this morning
lennie (at seaford) had 10mm up to 1.30,
i got 11.9mm up to 5.00
noarlunga AWS has 2.2mm up to 5.00.
not hard to work out who has the crappy
stuffed inaccurate rain guage.
always wondered why that piece of garbage
recorded lower than me.
and to think the BOM rely on this rubbish
for official records and stats.
as far as this AWS is concerned there was
a non event down here as far as rain goes.

could pretty much pencil this one in as a sub-tropical cyclone.
been a long time since anything reasonably decent has come
close to giving sustained land gale.
the stinger seems to be evaporating as it hits KI.
current score noarlunga aws 6.4mm, me 14.4mm,
a gain of 4.2 vs 2.5 over previous, understandable considering
the nature of the shotgun showers coming through.
previous was a general rainband and shouldn't have been such a
huge discrepancy.
