This watch affects people in the following weather forecast districts:
Taupo

Heavy showers and thunderstorms are over the central North Island this evening, and are slow moving. There is a risk some of these thunderstorms may become SEVERE with localised downpours of 25 to 40mm/hr over southern Taupo, northern Wanganui, Taihape and the Hawkes Bay ranges for a time early this evening. Rainfall of this intensity can cause surface and/or flash flooding, especially about low-lying areas such as streams, rivers or narrow valleys, and may also lead to slips. Showers in these areas should ease tonight.

Some better looking cloud to my SSW. Probably too late in the day now though to get any further than it has

Sattelite pix didn't show much

Nice to have a NW wind this morning for a change,been so little wind from that direction lately.

Enjoying the warmer weather here also, already 17C here.

I think the bitterly cold air in modelling east of NZ next week is something to watch, parts of NZ may well end up catching some of that.

[Manukau heads obs]

yes, going to be warm again
was 1.5C warmer than normal here for the 24 hours for the day yesterday than normal
which is negating the colder days earlier in the month
the sea breeze only made it onto the coastline here yesterday, real late too, at around 6pm

Lighter flow today so seabreeze convergence is more likely , isolated afternoon showers under the sea breeze line.
Currently fine here, 20C, dewpoint 13C

[jamie]

looking far more likely of getting a storm here today going by MS latest outlook.

RE yesterdays storms. A firend on the Napier Taihape road had a 2hour thunderstorm yesterday with torrential rain about the area.

[NZstorm]

Looking like eastern places (Gisborne/Napier) will be the best spot for thunder today. But some cb's also developing further inland toward BOP.

18Z Lifted index chart here for 4pm today with surface wind flows included.

[jamie]

It has clouded over significantly here now but is getting more humid. I'm not sure we are going to see anything develop here now

[Manukau heads obs]

I can see some nice looking build ups from here...looks to be eastern north waikato?
edit....up, rain radar shows western Hauraki plains....Tahuna area?

[jamie]

Yea great view from here. Looks like it could spark up any minute

A line of Cu running east of Auckland is part of the same line.

Sorry if one of the mods want to merge these three posts go for it. Kept hitting the wrong buttons on my phone.

[jamie]

Good fuel feeding this with a nice 21.6/16 breeze flowing right into the convergence zone

just saw a very small funnel drop for 30 seconds from below the tcu in this shot. It's really building fast now

[Storm Struck]

Some Cumulus developed here around 10am although reasonably weak went up fairly fast with a few light showers around midday at work, i see one of the showers may have been a brief thunderstorm up near Waikari North Canterbury going by the hourly radars.
Not bad for a weak front really might be catching some of that cold unstable air Australia has been having.
Next week could be interesting with a few fronts here and there.

from just left of the tree in that photo?

[jamie]

Which tree lol? It was between the 2nd from left and 3rd from left. In that gap.

It did look like there may have been but no there wasnt a thunderstorm Jase,dam it all,though there was a heavy shower coming through Waipara

[David]

Possibly some very warm upper air moving over NZ in a week, though the models could still change...

[spwill]

Yes, possible warm air off Australia early Dec.
Might be some cold weather around thurs but GFS is keeping this east of NZ at this stage.

I like the bath out in the middle of the paddock. An unusual feature for a thunderstorm photo
