General December Weather

[NZstorm]

I like what GFS has done with the moisture for tomorrow. Brought it down towards Taupo where I will be.

As for the 3rd......wow!

Yes, the moisture looks good tomorrow with the 850mb dewpoint 10C. But the lapse rates look rather weak on the 12Z run, so looking more like heavy rain showers and just a little bit of lightning.

[spwill]

Looking like a humid trough to start 2016, back to anticyclonic from the about the 4th.
Showers not ideal for the campers but it will be warm, 1am temps look warm in the north.

Significant warm advection looking more likely so rain will be torrential for the campers!

[Richard]

Looking likely that there should be some useful rain for CHCH north too. Hopefully the models stay on track for the sake of many of the sad looking trees in this area, even a number of pines are looking half dead.

Definitely worth keeping an eye on this one.

Another beautiful day today with pleasant 24C. Looking like some very decent rain possible in the new year!

[Captain Salty]

looks like maybe a CB near Lewis Pass tonight

Tracker showing lightning around Lewis Pass.

The convergence over the North Island tomorrow pm looks to be across the Hunuas (east Auckland). So maybe a cb close to Auckland tomorrow.

I observed contrails in the sky here this afternoon, often indicates colder weather coming within a day or so.

So did I
One moved from the west and expanded.
The other moved slowly towards the west.
Both in a north to south direction, possibly at different levels.

EC still keen on around 50mm for mid and north Canterbury for the weekend, I have everything crossed that it happens, boy it was shocking to see how dry the countryside was around the Culverden area the other day...

[Richard]

Yes its getting bad alright Bradley. I'm down to 70cm in my well and dropping fast

[David]

Latest GFS showing over 100mm rain here from the upcoming weather system. Starting right about the turn of the new year...

[spwill]

It is starting to get dry here now with only 25mm so far for December. I see Whangaporoa got 58.6mm on Xmas Eve.

[NZstorm]

Just about time to kick off a thread on the new years storm. Looking like significant rain and gales for the upper half of the North Island and other parts of NZ could be affected depending on trajectory of system. 300mm not out of the question for eastern Northland and Coromandal.

[Orion]

Rain here sounding nice on the roof at present

[NZ Thunderstorm Soc]

Yes, it is sad to say that the rain is falling mainly out at sea instead of inland. Shame that some sort of artificial means is needed to push the rain onshore and over places that need it

[Richard]

Certainly had no rain here and looking like there will be next to nothing this weekend as well. So ending the year with 340mm

Or, some sort of artificial means has been preventing it

Looks like you've had 30-40mm more then Culverden Richard, do you usually get slightly more then them?

[David]

Wow, already 25C at 10.10am in the morning, it sure is a warm one out there today.

That was from a woman who keeps good records, her and her hubie are 10km west of Culverden, they probably get a bit more being closer to the hills. Ive never kept records but now that there's the NIWA station on here it will all be done for me from now on

Just had a add up and i see Culverden in on 311mm for the year, wonder if anywhere has had lower?

[David]

Wow it just goes to show what a difference having good airflow makes to temperature readings. The fan in my weather station had got stuck for some reason. I just got it going again and the temperature reading has dropped 1.5 degrees in the following 7 minutes...

[Nev]

It is starting to get dry here now with only 25mm so far for December. I see Whangaporoa got 58.6mm on Xmas Eve.

Yes, with half of that 59mm at Whangaporoa falling in just 1 hour, or 43mm in just 2 hours.
Whitianga Aero also recorded 59mm that day, while Akld Aero only recorded 11mm.

We managed a more steady 38mm that arvo/evening... a very timely xmas top-up (43mm for month).
