General November Weather

[CHCH Weather Chaser]

Yes some much needed rain falling here at the moment, hopefully its quite a wet week as we have become very dry with the rather dominant westerlies prior to the last couple of weeks and very little rainfall. Interestingly soils a lot drier here for same time as last year but rainfall is comfortably up on last year for the year to date, obviously longer drier periods and when its rained its rained a bit!

Models did hint at perhaps some heavy rain Wednesday into Thursday but last couple of GFS runs has this low sliding further east now so not looking like anything particularly heavy anymore, but never the less should get 30mm + before the week is out I would think.

[Richard]

Yes but the MS have a high risk of heavy rain Thursday

Yes quite surprised by that actually. It looked much better yesterday when they had a low risk and now that its backed off they have put up a high risk...wait and see I guess. Steady rain here last 2 hours.

I'm amazed at how fast the hills have browned off these last few days. Badly need the rain so good that a decent drop is on its way.

[CHCH Weather Chaser]

10mm before today for November and 14mm last 30 days. 5mm this afternoon so far - keep coming please!

[mikestormchaser]

hmm quite and intence patch on the radar inland from timaru, even a small patch of purple in it. is that the rain radar playing funny reflectivity games or could it be some converagnce zone down that way?

[Richard]

11mm so far which is a start and hopefully more before the weekend,though it doesn't look good when the MetS come out with one of there 'bob each way' forecasts again,take Wednesday&Thursday, a high risk of heavy rain for Canterbury Thursday in yet total rainfall forcasted for those two days - Ashburton with 0.0mm and CHCH with 0.8mm

Not sure what to make of these claims in yesterday's Herald…

'Record temperature a surprise after gloomy forecast' - NZ Herald
5:30 AM Monday Nov 25, 2013 - By Jamie Morton, Ben Irwin

According to MetService, Auckland reached 26C on Saturday. The previous accessible record for November was 25.5C in 1974. … Yesterday, temperatures reached 24.7C. ...

Which site are they talking about? If it's Akld Aero, as the '25.5C in 1974' ref suggests, even though the airport's previous record was actually 25.6C set in 2008, then Saturday's 25.6C (rounded to '26C') only equalled its 2008 record.

And where did Sunday's 24.7C come from? Can't be Akld Aero, as that was down to 23.2C, while Whangaparaoa was up around 25.5C.

As previously mentioned, some NIWA Nov records that did fall on Saturday included:

Code: Select all

Site                  2013 Record   Previous Record

Auckland, Mangere        26.8C       26.7C in 1963
Auckland, Pukekohe       26.9C       25.8C in 2008
Hamilton, Ruakura        28.4C       28.1C in 2010

Jim did mention the Akld record of 26.8C last night btw - just didn't say where, when or from whom.

Precisely Richard. Even there 3 day maps that they modify showed huge back off. Really don't get them sometimes. Anyhow only patchy drizzle this morning and 18mm so far.

some pohutakawa trees flowering already here...

11mm so far which is a start and hopefully more before the weekend,though it doesn't look good when the MetS come out with one of there 'bob each way' forecasts again,take Wednesday&Thursday, a high risk of heavy rain for Canterbury Thursday in yet total rainfall forcasted for those two days - Ashburton with 0.0mm and CHCH with 0.8mm

Might be that the flow will be southeasterly, which means a Banks Peninsula rainshadow effect that shelters Chch somewhat.

Yep,but not the case for Ashburton though,anyway i see the forecast now is more line with the rainfall amount

[NZstorm]

January conditions again today with 26C.

[Richard]

Rains being steady all day with 20mm so far,another 10 would just be the bees knees

[David]

January conditions again today with 26C.

Yep we got to 26.0°C at 5.00pm thanks to the W-NW change. Unusual time of day for the maximum.
I thought it felt more like February actually

[CHCH Weather Chaser]

No rain today here, just overcast. Still 18mm for the event. 32mm for month.

[einzack]

up to 41.9mm for the month, but still such a low rainfall year.
haven't compared to NIWA records, but since I've been recording we had 2,217mm in 2011, 1,789mm in 2012 and so far are sitting on 1,402mm in 2013.
so very low.

I see Akld Aero finally beat its previous Nov record of 25.6C in 2008 with 25.9C yesterday.

Grey Lynn's 26.5C yesterday was also just 0.2C shy of its 2010 record.

[Richard]

28 mm of rain from this event with more drizzly stuff this morning,anything over 30mm now will have benefits for early summer

Just out of interest what was your max temp yesterday Nev?

[Nev]

Only got to 24.5C here yesterday. Highest temp so far was 25.9C on Sunday.

And just 2.0mm this week from Mon/Tue night...

[snowstormwatcher]

20mm here over the last couple of days. Drizzle currently and 12 degrees.

[Richard]

A total of 35mm from that last system with another 5mm yesterday

[David]

Apparently Ardmore Aero recorded an 81 km/h gust from the east between 12am and 1am yesterday. We only had gusts to 25 km/h here at the time.

[Manukau heads obs]

and easterly there does funnel around the top of the Hunua ranges a bit
