I haven’t seen any reports of snow on the Central Tablelands this morning. Webcams this morning showed sunshine but no snow, e.g this one at Oberon: http://oberon.liveweatherviews.com/

It was quite chilly here with the wind, fairly cloudy in the morning but mostly clear now. At the Airport at 3:00 PM it was 14° with an apparent temperature of 4° under 22-30 knot winds.

Hi Steve ….This afternoon I could see that the top of Mt Canobolas was still covered in snow as I viewed it driving around Orange. I believe the road to the very summit is still closed but the roads lower down have re-opened. Sadly I cannot go for a “pleasure drive” to see the snow up close as we are in lockdown here in Orange!

Does anyone think this has been a particularly cold winter, by Sydney standards?

We haven't had so many frosty mornings, but we seem to have had a more than an unusual amount of cold days.
There has been a lack of SE winds off the Tasman, which has helped, but there has been plenty of NW cloud bands, many containing rain, and plenty of cold changes, particularly over weekends, which I can vouch for watching my son play soccer on Saturdays. Although, this hasn't been the case over the past 3 weekends with the season on hold due to Covid restrictions.

I just feel as though this winter - or the past 5-6 weeks particularly, have felt colder than normal.

100% agree, I've felt this too, especially since mid-June.

Some stats back this up. At Parramatta, July has had 11 days below 17°C so far (not counting another likely one today). There will be a few more. On average (1991-2020) an entire July has 11 days below 17°C.

There have been 8 days below 16°C already (not counting another likely one today), compared to a monthly average of only 6.

Coldest in years.

Miserable days.

Nights haven't been as frosty. However moisture and cold temps have combined.

This winter has felt very chilly up here on the Central Coast as well. Quite a few days have struggled to reach 15°c and the dampness and windchill has made it feel colder. Feels more like a Melbourne winter than a Sydney winter.

Sun shining for the first time in 7 days down here (also the first to finally drop below 98% RH). Classic SW Slopes winter gloom—a huge 180 from the sunny borefest that was July 2020. And 5 snowy days as opposed to 1.

Hunters Hill running almost 3° C colder in maxes than this time last year (6.4° vs 9.2° C), and with about +100 mm extra precip.

Thank you @Jac0b

I thought it wasn't just me.
As a winter lover, I've been really soaking it in.

I'm sure it's the reasons I've given -

1. Lack of maritime air from the SE (which last winter seemed to have an abundance of).
2. Plenty of NW cloud bands and rainy days.
3. Plenty of further cloudy days without rain, but inhibiting normal sunshine warming.

We have cold mornings generally in winter, so these NW cloud bands have been keeping days much cooler I believe than what we would normally have without them and the extra sunshine.

I've enjoyed this colder than normal winter. It's a proper one like I used to remember as a kid throughout the 70's and 80's.

Very cold for this early in the evening, don't see it down to 2.5C at 9:30pm this often, and was only 4C a couple of hours ago too.
Will get a frost tonight for sure.
Generally a colder than average July so far for long term records like Tocal, by almost 1C for the maximum, about average for the minimums.

Has this Winter been cold? It feels like it. What about the numbers?

Bankstown is tracking 6.0° - 17.2° so far for July, compared with the long term average of 5.2° - 17.4° (52 years of record), so slightly warmer nights but average days. However, this follows a run of warmer Julys with regard to maxima, even if minima were about average or below (e.g 2018: 4.1° - 20.0°).

This year we seem to have had a number of raw, windy and often cloudy days with maxima in the mid teens but fewer of the calm, clear days that have featured in recent years. Bankstown didn’t have any maxima below 14° in 2017-2019 and just one in 2020. There were no maxima below 60°F (15.6°) in 2020 apart from a standout 13.3° in August.

Anyway, looking forward to the coming warm spell.

This morning, most Sydney sites will have experienced their coldest temperatures of the Winter so far, including 5.2° in the City, 1.5° at Bankstown and -2.1° at Camden and Richmond. Given that we are now in late July, with partly cloudy and possibly windy nights from tonight for several days, these are likely to be the coldest readings for 2021. All are colder than any readings in 2020, although unexceptional in the longer term, with the last colder readings having occured 2-3 years ago.

A nice, sunny day coming up, with a few days of average temperatures before it warms up early next week.

Marangaroo is about 5 km past Lithgow on the Great Western Highway. I stayed there a couple of days for a snow event back in 2015. It’s in a bit of a hollow, a fairly flat valley about 950 metres above sea level with hills either side, a classic frost hollow. This morning it bottomed out at -7.9° (17.8°F in the old money). That’s the coldest in two years but it fell to -11.1° there in 2018.

Was -0.6c in Penrith this morning, widespread frost on the way to work.

Decent frost out the front of my place in Glenbrook as well, temp dipped into the negatives.

As for July we should end up below average for both max and min temps even with this upcoming warm spell. That was after a below average min and max temps in June as well so its not just your imagination @Homer

.....And if that approaching westerly cloud band was about 6 hours earlier, today would have been yet another cold, cloudy/overcast day.

This weekend's event could be a 20cm+ system for the OP, and good settling for the BMs IMO. GFS seems to have the moisture making it a fair way east in the early hours of Sunday, so hoping to see some flakes here in the SHs. -5°C 850s and -13°C 700s will do it, moisture is the question. Snow down to ~500m IMO for the STs, and CTs if GFS sticks. Not often you see such widespread sub -4 850s

Some fairly cold temps today under this cloud mass.
Canberra/Tuggeranong have only topped out at 6.0 deg's each.
Glen Innes is currently at 4.5 deg's. 7.7 at Khancoban and 8.3 at Albury.
Even Grafton is currently on 12.7.
All this even before the cold air properly arrives over the weekend.

The current sat pic looks quite dynamic over SE Oz ahead of the major change approaching.
A massive area of cold air is behind this front. It's one of those changes where I wish there was a massive land mass below Australia, for obvious reasons

After some early light rain here, the skies cleared somewhat and there was broken sunshine for a few hours, enabling us to reach the average forecast max but the sky has closed in again and some light rain has fallen in the past hour or so. Temp has dropped back to 14.4 here, so another, cool/cold day today continuing the theme of this winter.

BOM including snow (quite rare) above 700m in the Illawarra forecast for Sunday. Also, snow in the Canberra forecast, snow above 600m for the STs, and 700m for the CTs!
Bom has been jumping around with this all week. At one stage sta/sun was 15mm of some sort of moisture, now just sun with 8mm. All I know it's going to be a good weekend to be at home and not working.

IIRC this cloudmass came in due west across WA from a low off the coast between 25 and 30*S. i.e.not from the Kimberleys. But I am just being pedantic. Looking at the sat pic there's more cloud and a 1017 hPa low 2000 km west of Geraldton. It's a cold dank winter and we're locked down:mad:

You'll note in my comments above I called it a westerly cloud band as a point of difference. ;)

It was a raw, chilly day for the most part with maybe an hour of sunshine around the middle of the day. This allowed the temperature to reach the forecast 17° in the Eastern parts of Sydney, including OH.

Here’s Naremburn Park around 3:00 PM this afternoon. It’s about 14° with solid overcast and passing light showers. The grass is looking decidedly dry. We’ve had regular light showers this Winter but total rainfall is tracking at about half the average over much of Sydney. It’s not owing to frost - I haven’t seen that here since the 80s.

Here on the Central Coast, there hasn't been any really heavy rain since March. At Gosford, the last day that had 50+ mm was on March 22nd. The combined total for April - July so far is 235.2mm compared to 678.6mm for January - March.

The north-west WA heat engine is starting up with mid-30's and sunny weather forecast for the coming week up there, and high 20's to low 30's for Alice springs, which has a July record of 31.6 (both it's June and July records are from 1996).

So that explains the forecast 23's coming up for Sydney next week. I think it was a similar pattern that caused a straight week of mid-20's in the first week of August 2011, and also a straight week of low-mid 20's in the last week of July 1975, which is really quite exceptional. I don't think next week will be like that extent though.

Will nudge the high teens here on the 31st I think, that means mid- possibly even high- 20s in Sydney. The record for July at both Canberra and Goulburn is just under 20C. There has been near record heat in the Kimberleys the past couple of days which tends to filter down here in NW winds. But I'll enjoy this snow event first. Going snow chasing tomorrow, either OP or Anglers Reach/Connors Hill again. Might be the last chance of the winter depending (a) on the arrival of spring and (b) potential lockdowns in regional NSW.

Won't be days of record heat but if the heat pulse does occur on July 31 as currently forecast, some July records may be under threat. Interesting that the Alice records are from 1996, which was an otherwise cool and wet year. Might have had a negative IOD similar to this year, and there would be a strong correlation between Kimberley heat and higher SSTs off NW WA.

This late July/early August heatwave has been a common occurrance in the past 10-15 years, though. My birthday is July 29; growing up in the 90s it was usually always chilly in Sydney. For most of the past 10 years it has felt like the start of spring. I think the tendency for earlier spring-like warmups is directly related to CO2 forcing.

It will be plenty cold enough for snow in the upper BMs, it's just a matter of how much precip makes it over there. Even here at 700 m I am expecting a minimum around 2C with a shower or two about.

The highest PWS's on the OP have been sitting around 2-3C most of the day. Windy indicates the precip temp will be around -1 for Shooters Hill for most of tomorrow; should be a good day. I find the temps quoted on Windy are quite accurate in gauging the temp at which precip will fall. You usually add 2-3C for the max, assuming enough sunshine.

Will be one of those July weeks where I'll be sweltering coming of a 15 degree tomorrow ahaha. Speaking on heat engine the NT will start consistently go above 35 degrees this week. But this heat coming down i believe is more down to the favourable LWT, very long-fetch to drag the heat over.

The one metric i'll be watching for a hot end to year is when Fitzroy Crossing WA sees it's first 40 degree day. Heat in Jan, Feb will be dependent on Monsoon and Tropical Cyclone activity.

They used to mention blizzards often, though. Looking at that forecast I would go with ‘severe blizzard conditions possible’ for TTS.
