As per Homer's request, here is a thread. Post obs and forecasts etc in this thread. Not much to say here for me, it's been pretty well covered in the DTD thread.

I dare say a few people unaware of this change are going to get quite a surprise.
Dave M's first frosts of the season are in store as well.
Anzac Day once again is the turning of the seasons.
Very spot on this year.

Certainly wasn't cold overnight. Was at the dawn service this morning and in years gone past a jumper is normally required at that time of the morning, but not today was quite mild with a light NE breeze blowing.
It was a beautiful sunrise too this morning!!

Forecasted to get to 27c here today and Bulahdelah forecasted to get to 29c.
Somehow I think those temps are a couple degrees to high, anyway time will tell.

The sunrise was one that just gave you that feeling of contemplation.

Shouldn't become an ECL. Most model tracks (including this one from the UKMO model) show the MSLP low moving in a SE track and undergoing RI a fair way from the Aussie Mainland, rendering it a Tasman Low.

Persistence of moonsonal troughing this late in season is the wrecking ball of solid cold fronts

Hearing the odd distant rumble here. Some very warm temps this late in year ahead of this. Some 28's western Sydney and Hunter region. Wonder how this 3 day hottish streak stacks up historically for Sydney. Paging Steve. Come in Steve

It was sunny, humid and quite warm when I walked to the shops around noon. It felt like Summer. I see that a number of Sydney stations peaked around 27-28 in the early afternoon. OH peaked at exactly 80 deg F, very warm for late April. Looks like the BOM were right with the first Anzac Day forecast of 27C.

It's now completely overcast but still warm. Apart from a few spots it hasn't started raining here yet.

We missed the sunny part here at least from 10am onwards, not sure about earlier than that. Still felt pleasantly warm with quite a strong breeze but now it is cooler after some moderate rain.

Actually, I need to adjust my last post. While it didn't look like it was raining when I looked out the window from the sofa, I found when I went outside that it was raining lightly and had been apparently for a while. The pace is picking up now, although judging by the radar the rain band will pass soon.

Cold lovers might find this edifying. Looking at just a couple of years that had a similar or even warmer string of days in late April including Anzac day in Sydney, I notice that each month of winter was below average. Some months noticably so. This is for years 1986 and 1953. I might do a bit more digging on this.

Interesting stuff Knot. 1986 was an excellent winter with snow on the ground for a few weeks in the higher parts of the CT's from what I've read.

Oops I'm thinking of 1990, but 1986 I think had an extremely good cold front with sleet in the higher parts of Sydney. 25th July 1986 I think.

On April 26, 1953, it reached 30.2 at OH, following 29.8 on Anzac Day. Interestingly (for weather nerds), they were the hottest two days of the very cool 'Summer' of 1952/53, if you extend the definition to include March and April. It had not reached 30 there since Nov 16 (when 31.7). The average maximum (rounded) in each of December to April was 24, 24, 24, 24 and 24.

Some past and present posters here would have loved that Summer, some would have hated it.

The Winter that followed was average, which compared to what we've got used to in recent decades means cold.

1986 got up to 29C from memory, the day before Anzac Day.
Can't recall it staying warm beyond Anzac Day though.
Winter was cold, and most notable for the incredible rainfall in August that year. (as was 1998)
There have been some recent years with very hot temps in the last week of April, in fact temps hotter than the May record.
Unlikely this year though.

2013 though had a string of hot late April days, then record hot July's and September. (and August not that far behind 1995 either).
There is often very little correlation between seasons in central NSW where most of us are, which makes it interesting.
