Seems to be more action coming, a large area of cells to the West & south of Cowra, down to the border region.

Another hour or so might see that stuff up this way.

The northern tablelands is going to get absolutely hammered by that squall line. It produced a 95km/h gust at Gunnedah Ap and 96km/h at Moree. The winds will probably be even stronger on the tablelands.

Nice temps in the basin at the moment.
Richmond 31/25 rounded just now. Most other places not far behind.

Anyone notice Moruya Airport got to 36.1 earlier?

I suppose it's a bit early to call this one a fizzer but compared to what was forecast it is a bit underwhelming. I suppose there is still time for something to develop but I can't see the heavy falls and dangerous storms that were forecast.

This is the summer that just keeps on giving. Kyushu island type stuff there. I'll take their 6C and possible snow right now, though.

The humidity and warmth here is absolutely beyond belief. Far out it is oppressively humid!!

There's another line of rain coming in from the south west currently, in a line from Nowra to Orange, but there's not much showing up on the lightning tracker.

Was sunny during my last post but now it is raining with full cloud cover. Absolutely odd weather.

I haven't tracked the progression of this system closely, so I was shocked to find that Port Pirie recorded a 25C dewpoint yesterday evening! No wonder the storms over there had so much grunt. We, of course, get the stifling humidity but no storms; such is the way of the climate balance at this point in time.

It certainly is a big shame that nothing fired around here today; it's very rare to get such high humidity with strong steering winds.

I must say this moderate rain atm is very pleasant and welcomed. Still warm outside but not oppressive.

Hopefully the line of rain mentioned by HRH Homes delivers a few more mm Greg. It looks promising on the radar across the Bx district. Passing thru here it bore a distinctly wintry character (except for the temps) with a burst of heavy rain accompanied by strong wind shifting sou'westerly. Orange AP gauge has moved rapidly into the 30's, but things should start to clear now.

The dewpoint at Badgerys Creek just spiked at an eye-popping 25.6C. That's about as high as I've ever seen in Sydney, on a par with the notorious February 2011 heatwave.

Got some sunshine and awesome safe surf down Cronulla way just now, and came out the water to a steamy 30C. Wind wise, virtually dead calm.

You're right, I just got a decent fall of 12mm to bring me up to 25mm for the day, not so bad and a couple of days not needing to use the sprinklers. Still I don't think the system quite lived up to the forecast, though there were some quite decent falls.

Both Gabo Island and Green Cape have has 100 km/h peak gusts in the past hour or so, from the south west. Gabo still averaging 74 km/h with gusts to 98km/h.
Grafton had a 93 km/h gust when that storm passed through.
Cabramurra 106, Perisher 98 and Thredbo 113 have also had notable wind gusts.

So, in some way, the BOM's warnings were justified to an extent.
What most of us missed out on was the lightning and thunder that gives us the feel of a real storm.
Surprisingly, the winds have been quite calm here for most of the day, with just the odd gusty interlude.

Those gusts aren't that special for that SE corner and the Alpine peaks, though. A little bit out of the ordinary in summer, granted. I've noticed that Gabo and Green Cape are getting windier more often, probably something to do with the massive SST gradient between Bass Strait and the Tasman.

I still call this a fizzer for most of the state; the NWSP scored an impressive gust front as mentioned earlier. Looking forward to a relatively mild weekend.

Obs Hill Max temp today of 29.1C (App temp 32.5C) so far at 7:10pm and possibly still rising. What's the record for the latest in the day max temp for Obs Hill in Summer months or January?

Max temperatures (and minima) can happen any time day or night.

For a coastal station like OH, on a hot day, it's not that uncommon for the temperature to rise after sunset and even into the small hours if a sea breeze, that has kept the location relatively cool all day, fails and lets the hot air in. This happened last Friday when OH had its max of 30.5 at around 2:30AM. Something similar can happen in Winter in an East Coast Low, when the temperature might rise at night after a cold day when winds swing around to SE.

Then of course you have the common situation of maximum at or just before 9:00AM the following day when it warms quickly the following morning after a cool, wet or (for coastal stations) sea breezy day.

The sun here has finally come out properly, just in time to set. The Southerly will be here seen, passed through Bellambi just before 8:00PM.
