Potential Nationwide Snow Event Sunday 8th August 2021

[darcyplumb]

That holiday park sits at 80 metres...temp dropping fast here in town!

Just stuck my head out the front door and there’s the odd bit of sleet in amongst the rain.

[Chris W]

5.7C and raining away in Lyttelton

[jamesh]

4.6C in Burnside, CHC. Dropped from around 5.4C at 7am. Moderate rain.

[Bradley]

Snowing heavily in Methven, the really cold air that will allow it to snow down to sea level is still 2-3 hours away, unfortunately this heavy rain will be gone by then…

[MoorfNZ]

Here at Waddington, 300asl, we have a few flakes within increasingly sleety heavy falling rain.

[Orion]

My Westerfield Spy at around 171m reports "big fat white flakes beginning to settle".

My Westerfield Spy at around 171m reports "big fat white flakes beginning to settle".

Ooooooh it’s getting closer!

[Lawrence]

Just heavy showers here at the moment with a few icey sleet drops added in the mix. Next report in an hour.

[Chris W]

The top 300m or so of Mt Herbert and Mt Evans have a good white dusting with it snowing heavily up there. Green and rainy below that.

[MoorfNZ]

Just started snowing in Waddington (300asl)...

[Razor]

I trust Mrs Razor is safe somewhere?

Yes thanks Tony, they are well domiciled in Greymouth and ready to sit out whatever follows thanks to the Gin Distillery in Reefton

And true to form taking husbandly advice on board they left at 6am and have had only rain as far as Castle Hill but are now sat at the top of Porters Pass with the road just closing. Sigh. No doubt they'll get down, but.....

[darcyplumb]

Sleeting in Ashburton now. Very chunky on my windscreen.

Coming down fast in Waddington, ground white.

[Tracy Herbert]

Still raining in Rakaia. Just checked my business cameras and nice to see it snowing in Methven and settling. (Although not nice knowing we might not get to our business tomorrow if we end up with large accumulations)

[Cyclone Tracy]

Fetch, current temp difference of 15c sea surface to 850 hPa temp converting into frictional convergence over land. Lovely ocean effect

[Northsouth]

CT where are you currently picking the LP in relation to models. It seems further south. Secondly, are you seeing this main band of moisture feeding into foothills. On very light precip within 10km of them which seems unusual.

[Dean.]

Snowing in Ashburton at 108 metres

[trickytiger]

Snow in the rain in temuka

Circulation is starting to develop at 850 hPa over the upper SI, surface low will develop further in the next few hours around Cook strait. Attaching the latest overlay of wind speed and direction at @950 hPa, with surface barometric observations and moisture in the mid levels gives a good picture. Atmospheric snow machine.

[Roseo]

Snowing in darfield. Settling too

[Thunder081]

Pouring down in Johnsonville, Wellington and there was thunder and lightning at 9:17am!!
