General December Weather

[jamie]

looks like a fantastic week to come after tuesday.
I also like the trend in the patterns with lows beginning to form in the north tasman sea.

as for today the sun really needs to get its A into G. still very cloudy here.

[David]

Lots of good surface heating going on here, temperature over 22C, dewpoint 17-18C

[spwill]

The lower cloud has just cleared here, have sunshine through high cloud.

[Michael]

Suns out here,feels like summer,little wind too.

[NZstorm]

Just looking at the latest midday sounding from NZWP, its looks a little bit capped today. There will need to be a very warm afternoon to get cb's going, looking like temps above 25C for any convection to occur around here.

[bmo]

We've broken the 25c mark here! But some very dark clouds in the surrounding area.....

Just looking at the latest midday sounding from NZWP, its looks a little bit capped today. There will need to be a very warm afternoon to get cb's going, looking like temps above 25C for any convection to occur around here.

Stable looking skies around Auckland, no towering Cu. High cloud/sunnyspells, 24C, dewpoint 18C.

Heaps of Crisp Towing Cumulus going here, had a look at the latest models 18Z:

Looks very good for this arvo in the Waikato, very humid potent SFC conditions here with a DP at 19°C.

Upper air seems to be sufficient at around -18°C @ 500mb since this occuring with DTSH, i think Waikato could be in for a good chance of a storm later on.

Yea I had a look at sounding a Whenuapai and did look capped, but that doesnt mean it can't happen down here

Attached below some CAPE with LI values on the 18Z run of the GFS, with 500mb temps. times from 2PM-5PM.

[Tornado Tim]

Oh boy man is it getting humid here, DP now at 20°C @ Jamies and my Station.

[spwill]

I see some small towering Cu now over southern parts of Auckland, some sea breeze convergence.

[David]

This feels like our warmest day so far (of spring & summer), max of 24 degrees and humid. Pity about the stable skies though!

[ricky]

Almost made 25 degrees here, I like the look of that dry slot in the sounding from 850 up to 500, if anything breaks through that often seems to make for stronger lightning..

[jamie]

man alive its warm! wouldnt call it hot but by far the warmest day since winter. mugginess making it feel warm.

Yea things look to be trying but still lacking a bit of surface heat here i think. Once it sits above 25 for an hour or two like it is now i think by 5 we should see some good development around here.

[Area51]

21C DP 18C here at Auckland Intl Airport, wind out of 210T 5-10kts. Dark cloud base to the NNW but nothing much on the radar as yet.

[ricky]

I see Southern Hawkes bay and just offshore in the far North are first up with the thunderstorms this afternoon

[Manukau heads obs]

yes, I am picking up strikes from the far north

[borris89]

Sure was/is some good storms south of Hastings today. Heard quite a bit of thunder and saw one CG while I was working outside

[Manukau heads obs]

unstable looking sky here at the moment...with towering alto cumulus
Westerly breeze hwere...if the NE sea breeze convergence can get going over the auckland isthmus things could get going?

the Hawkes bay has done well lately for thunderstorms!

[Manukau heads obs]

looks like mangatangi area getting good builds up (nth waikato area)
can see them from here and showing on rain radar now

[borris89]

Just some photo's of the distant CBs down central Hawkes Bay way

[jamie]

Westerly picking up here so that will be the sea breeze coming in. Cb to my east with what looks to be hail falling from it

[Manukau heads obs]

Huntly area now...big white towering clouds I can see from here

I am picking up strikes from the hawkes bay now...so good and strong CB's down there....looks very impressive on rain radar

M/S onto it

[Tornado Tim]

Stuff now really ramping up, very crisp and bright convection now (best I have seen in a while...)

[NZstorm]

Distant Cb out to the south there now, in the direction of the Kaimais.

[CHCH Weather Chaser]

Patchy drizzle, nothing wetting the ground. Being sheltered from the majority due to the band coming from the SE - ie. BP protecting us. Cooler day today, reaching around 18 degrees.
