Highest Gusts (km/h) ℅ MetService for June 08

Shouldn't that read July 08?

Oops, yes. Have amended that now.

So this morning when out with the cows I got accidentally caught in a crazy storm. We lost two big trees, another snapped half way up and two of our hedge plants got snapped. I haven’t had a chance to take photos. Wind on the station peaked at 94km/hr. In the worst of it I couldn’t drive the quad bike and had to hop off and hide behind it. The bike was shaking heavily as if someone was on it and rocking it side to side.

Just had some of the best sounding thunder I’ve ever heard. Must be the cold air. 3 very good sub 10 second flash to kaboom.

Seen a few flashes of IC lightning out to SW while out for a run. Too far off to hear thunder.

Thought I could hear some distant thunder.

Wow, the Kaimai forcefeild is doing it's thing protecting me from the weather Jamie describes

Started my day driving through to Rotoiti, approaching the SH33/30 turnoff (Tikitere - Hells Gate) had some serious bands of wind driven high rate rain falling. Later at Rotoiti, post the event some decent Mamatus, photo doesn't do it justice. Sadly no thunder heard nor lightning seen.

Grr... That M word again.

Wasn't there, but would wager high it was nothing resembling an actual tornado.

Where is the delet icon?

^ Raining steadily here now, sounds quite heavy.

More thunder here now.
The NRFA PWS at Hamilton AIrport seems to record higher wind speed than Metservice's site only a few hundred metres distant, possibly getting some funneling around buildings. Has recorded gusts close to or over 80km/hr several times today.

Must be pizzing down in ChCh or around some areas according to the revamped Rakaia radar?
The rain sounded initially heavy, here, but quickly eased off with a disappointing total of only 5.3mm to 10pm.

Yeah, there's also a PWS near Whakatane Aero that also fairly consistently records higher gusts than the airport (particularly during strong winds), probably also due to surface terrain funnelling.

Here's another list of the highest gusts recorded over the last 2 days.
(I wonder if White Island was venting gas last night?)

It was quite heavy around 10-11pm and the radar was showing a fair few purple echoes across from Chch inland.

We did get a period of rain overnight (about 6mm at Jeff's station), but I don't recall any hail or thunder. Also a dusting of snow on Mt Herbert this morning.

Icy looking clouds visible to west of Chch late this afternoon.

Yes, Ben. Noticed that on the way home from Halswell today looking towards Mt. Hutt from Thompsons Track.

Vector has issued a storm warning for Sunday 15 July between 6 AM and 9 PM. Just checked the three day forecast and there may be some wild weather action coming up.

Front at 0300 hours 15 July 2018

Also the tides are the biggest we get in Auckland. tommorow (sun) 0853 -3.6m / 2119 -3.7m. Should provide some good action at my local narrow neck beach as well as the whole east coast with the gale NE

The front at least is on the move and gfs has it through by mid morning tomorrow.

Weather looking milder for the next week with daily highs around 16C for Auckland.

Another settled day here,have we ever had a more boring winter?

Nope - maybe 2005 but the September snow in Christchurch certainly made up for the boring winter weather, too much to ask for another event like that to happen again though you’d think...
