Heard a few distant rumbles to the W-NW. Rain has pushed the dewpoint up to 18C.

A beautiful cool change with the SW and rain coming in. The sky is darkening and it’s pretty solid rain, no rumbles heard in the centre of town though.

Queenstown airport at 5pm reported a southerly of 43knots, gusting 57knots, temperature 6C and thunder! Very odd for January.

Very pleasant temp drop of 12c to 20C with the Southerly.
EDIT: winds went WSW from the NW, front still to come thru

First of the southerly hissing through here now, sky very black to the south.

Edit to add: has become very dark very quickly!

Definitely a gust front forming up on radar, and yep that photo shows it!

Impressive looking gust front.
Had a quick shower of sweet bugger all, bit more would be nice.

Southerly just reached Templeton, wheelie bins falling like skittles and power dropping out.

Hitting now, nasty!

Some house-shaking gusts interspersed with calmer, breezy periods. This is really cool to watch especially knowing that it's a brief interlude to a very warm period in summer.

I think the Invercargill flight is trying to climb above the storm

Just hit here, gales from one direction and now from another.

That southerly change was impressive. The MetService website gives gusts to 139km/hr at Le Bons Bay, 111km/hr at Lyttelton and 94km/hr at Christchurch Airport.

Are there any published papers on the mechanism of this type of weather event?

Press article has an incredible view of the front coming in: https://i.stuff.co.nz/national/11012407 ... of-country

just add the Kaikoura Airport reading was 142km/h.

I remember flying into Dunedin a few years ago and seeing one of these gust fronts from the air. The sea under the gust from was white. Would have made a good photo if I was organised.

All clear after the short burst of rain last night. More than happy to have a fairly dry January, as in the last 4 years (since Feb 2015 that is) we have generally been deprived of dry sunny midsummer months. In addition, 3 of the 4 Marches were mediocre.

I'm Guessing the 173kph recorded at kaikoura was on the peninsula then NZstorm?
