There was certainly snowflakes over southern/ sw parts of the region. My experience of the day was snowflakes near Pukekohe and soft hail in Mt Eden.

There was nothing interesting in Howick that day sadly... I do remember it was damn cold though. My data history shows it was 5C at midday.

Yep I remember driving in Hamilton and going from sleet to full flakes. Exciting day that one!

With the month half done its looking like bucking the trend of the year to date here in ChCh with a colder than average month, the mean temp is just 4.3 degrees at Jeffs Hoon Hay Station, the most local to me (for eg), month to date.

It's not just Chch. Temps for most of the South Island have averaged at least 2-3C below normal so far. Temps for the North Island have also averaged between 0.5C and 1.5C below normal. So even if the rest of this month is warmer than normal, it still looks like August will end up being the country's first colder than normal month this year.

Looking at the next 7-10 days as well it doesn't look like there's any real warmth on the way either so almost certainly it will end up being a colder than average month for most of New Zealand, exactly what Tony predicted months ago so credit goes to him!

Looking like some great spring weather in the coming days.

I see MS have a blog comparing this month's recent cold spell with the August 2011 snow event.
Also interesting looking back at the 2011 blog…

Nice blog entry. Seldom noted is the brilliant clear weather that followed in some areas, with Nelson and Blenheim setting sunshine records.

I see 2011 was a la nina year while August this year has been neutral but on the la nina side of neutral. The AAO has been strongly negative this August. I think when the AAO is strongly negative there is a better chance of cold air reaching NZ.

Spring is in the air, plenty of sunshine with lows 3-4C and highs 16-17C both today and yesterday. Photo is one of our flowering cherry trees at the moment

Nice blossom, David.

Visibility rapidly diminishing here as fog closes in, has gone from say 400m to 100m in the last five minutes.

NZ Thunderstorm Soc · Wed 17/08/2016 18:00

Yes. Fog moving in here from about half an hour ago, from the south.

Heaviest fog i can remember here in West Melton!!

Richard · Unread post by **Richard** » Thu 18/08/2016 08:58

Clear sky here this morning.
Still no sign of a good rain maker for eastern SI for Aug with ground water tables lower this winter than last, coming up 22months since the last 'wetter than average' month...will Sep bring the rains?

jamie · Unread post by **jamie** » Thu 18/08/2016 10:00

Clear in Auckland...beautiful. Fog all the way to the top of the bombays then into clear blue.

I thought January was quite wet for North Canterbury Richard? For example even Culverden got 79mm?

Funny how after 3days in a row of clear calm weather there was some fog about this morning. There has been no rain to add any moisture to the ground, so I wonder what causes the difference. Sun was already poking through by the time I got to work about 9am however.

From memory it was very hit and miss with those Jan events some areas like ChCh got good falls but others got nothing. Such is the nature of NW spillover events

Could be a good active system brewing in a weeks time going by GFS, especially for West Coast

Razor is spot on, a storm dumped 43mm here in 15mins but 2kms away got nothing, Culverden picked up a different storm on the same day. But on the whole much of the area received about average rainfalls

Richard · Unread post by **Richard** » Thu 18/08/2016 12:55

Cheviot received 69mm for Jan, so that wouldn't be much over the average long term

I've done two day trips this year. Best quality snow I've had there in 10 years of using it. 2nd day I went was best day I've ever had up there.

I always leave here at 5am and hit national park at 7.30. Gives me option to go to turoa if that's the best condition slope. Any later than that, especially on weekend or school holiday, and your stuck in a traffic jam or parked at the bottom.
