Neat to be in the thick of it but I'm getting a tow out of here to lower ground so we are not stuck here for days.

Just driven through there and there sure is. A few cm coating the hills and small amounts on the roadside of SH1. In Taupo heavy rain with odd wet snowflake.

Slight sprinkling on Port Hills to low levels visible this morning, but gone now. BP 'snow-shadow' still sheltering central areas of Chch.

Only 2C in Taupo at midday!

Just had a good heavy graupel shower before enough to start settling against the fence, a few surface models point to these showers continuing overnight with 850mb temps around -8c.
Although upper air is -30c I wonder if the snowline could drop back down again for a short period, the met service 3 day map does show the purple snow line over the city from 3am to 9am

Yes and was almost snowing. Heavy wet sleet at times.

The amount of snow varied a lot in and around this area, to my west the hills of 600m asl received nothing while to the north the same height hills are just plastered with snow.

Cold wintry day here with the odd wintry shower coming through.
Nothing much really to write home about, but with today's maximum of 3.6C, it would be the coldest day of the year here, so far, this year.

Tongue of blue extending northwest from Napier-Taupo area towards Rotorua/South Waikato in recent radar. Only 3-4C temps at Rotorua stations, so snow easily low down nearby.

I daresay the super rugby final will be very similar conditions to the June 2008 All Blacks vs Ireland match when the Irish players were in distress after the match from the 4C temp, 50kmh southerly and horizontal rain!!

Was that the one where BoD was quoted saying they were the worst conditions he'd ever played in?

It seems unlikely. That sort of weather is pretty common all across the British Isles for about 4-5 months of the year!

Yep that's the game Tunster - I thought the same thing that the UK must get similar conditions regularly in the playing season but clearly not if Brian O'Driscoll said that!!

Snowing here Cracroft, and settling. Just when we had given up on this system in Christchurch!

Just a slight change of airflow direction while it's still a very cold airmass. Just a sleety shower in St Albans, precipitation probably too light or snow here.

Tiny bit of snow overnight in Ohakune town

Working about 100m up cashmere hills today. Lightly snowing up here.

Yup snowing down here too, light flurries at the foot of the hills

My staff member in Little River unable to get out to work this morning due to heavy snow falling...if only it could find the oomph to get round the Peninsula!

mikestormchaser · Unread post by **mikestormchaser** » Mon 08/08/2016 10:54

Seems there could be a small band coming up more towards cashmere now. Maybe fizzle out though. Or get sucked into the peninsula again

I really wish NIWA would stop comparing apples with oranges, both in their Climate Summaries and when issuing inaccurate and misleading statements like the one quoted in this story.

It claims that Queenstown recorded -7C on Sunday morning, making it Queenstown's 2nd lowest August temp since records began in 1871.

Queenstown Aero in Frankton actually recorded a T-min of -6.5C on Sunday morning according to MS, which (along with 1995) does make it the airport's 2nd equal lowest August temp since records began there in 1969 (-7.8C in 1972 being the lowest).

However, NIWA's generally warmer older site near Queenstown Gardens has an average August T-min that's 1.4C higher than the airport. Not surprisingly, it only recorded -5.1C on Sunday morning. So from records spanning 1871-1880 and 1930-2016, it has recorded colder days in 1957, 1952, 1939, 1938 and 1878 (the latter being the coldest with -6.1C).
