Active trough and depression Oct 13th-15th

[tich]

Been rather dry on this part of town, showers more going inland i reakon

Actually persistent rain/shower activity to the north today - on radar, the band's lingering in a line over North Canterbury, including the Amberley/Waipara area.

[TonyT]

We had showers from about midday till 7pm.

[Manukau heads obs]

showers getting more beefy now,...just had one go through..a coldie too...only 9.7oC now straight after...

[NZstorm]

My Convective forecast
Thunderstorms unlikely over NZ today but there is a 10% chance of thunder with that SW change in Canterbury this afternoon. Given that surface parameters are likley to be unfavourable (low moisture/no sea breeze) it looks likely to be just a squally shower with the change. Some heavy squally showers for the west and north of the country as well easing off this evening.

[David]

No Thunderstorms over NZ today

How do you know that there won't be any thunder when MS has forecast a high risk for this afternoon?

Strange how still there's been next to no rain here, and I thought it was supposed to be windy last night but somehow it got down to 7 degrees.

[NZstorm]

I edited to 'unlikely rather than No'

Strange how still there's been next to no rain here

We have had some quite heavy showers here in Grey Lynn.

This weather looks more like June than October. I see Christchurch Airport have 0C this morning.

[Michael]

Must be global warming causing this

Must be in error then. ChCh city currently 11 degrees, low last night was 7. No way was it anywhere near 0 at the airport

[Michael]

The people who record the data must be drunk or on something last night,in this morns herald shows all 10 AK localities well over 100mm of rain this month ranging from 154.8mm at Beachlands to 231.6 in Waiuku.I dont think we had even 100mm this month to date

[spwill]

ChCh city currently 11 degrees, low last night was 7

Yes, frosty at the Airport (inland location), down to 0C there.

[Manukau heads obs]

just taled to a local farmer.....close lightning/thunder and a bit of hail at 5:30am this morning (west coast here)

Yes, frosty at the Airport (inland location), down to 0C there.

There is absolutely no way that you could convince me that is accurate. Given it was still reporting 0 degrees at 10am I think you'll find its a glitch

1.3C at 06:30 this morning at my place (Hillmorton), airport was showing 1C at 6am.

Well it certainly wasn't that cold walking accross Hagley Park at 6.30am- in fact it was norwest and mild

CCC weather station reports a minimum of 6.5 in the Central city this morning

I don't see what's so hard to believe.. and where do you get that it's 0C at 10am? NZCH has it at 11C.

Here are the METAR observations, see for yourself! Shows that it was frosty there from 3am and quickly warming up by 8am.

Lightning activity is starting to pick up off Buller i've noticed.

[Paul Mallinson]

Scattered heavy showers with small hail and a few lightning strikes moved over Waikato, Auckland and Northland within a couple of hours either side of midnight last night.

Just saying its highly unusual to be so much warmer only 10km away here in ChCh CBD- as per the Council wensite it only went down to 6.5 here. There was no sign of it in the CBD or Hagley as mentioed...I see 5 mins after I posted the airport reading went from 0 degrees to 11 so I guess the nor west arrived there too

CCC weather station reports a minimum of 6.5 in the Central city this morning

I think that one is on the roof of the CCC building - 5 storeys up?

[jamie]

im rather dissapointed with the weather today...metservice got my hopes up for an action packed day but nothing is happening...unless its ment to happen later?

[Storm Struck]

Some rather impressive CU towering from the North right around to the south now .
Wind has been NE all day and still is now, just shows what can happen without ridging influence of a NW flow.
Perhaps a moderate chance this evening .
Cheers
Jason.

[NZ Thunderstorm Soc]

A few 'fists' going up right above at the moment but nothing really to get excited about
Yes, there was a frost here this morning as I slipped over on the decking.
Down to 0.1ºC in the screen and minus 2.8 on the grass.

Yes I manage that most Winters - can get quite dangerous if it is slippery frost (frozen dew)

How do you get the temperature out of this jumbled code?

[Gary McConnochie]

Google "metar" and you will learn how to decode the code.

[mikestormchaser]

Yeah i notice the CU around aswel this evening/ afternoon.
With that S up against the NE good signs there, wensday sounds way better though!

[Storm Struck]

Was looking quite good before will post a few pics later.
But just lacked something as it just capped and got rugged at a certain height.
Still great to see at this time of the year, looks like a few showers coming up the coast though.
Hopefully a break in the ridging will allow a NE to undercut before the change on Wednesday .
Cheers
Jason.
