General February Weather

[Chris Raine]

Cb's to east of Greymouth .No rain in town at this stage

[spike_01]

Light shower in Ngaio ( Wellington ) right now. Nothing exciting

[Manukau heads obs]

good to get those showers today (5mm here)
although places further north of me missed out (the manukau is a bit of a 'sink hole' for showers from the east)

[mikestormchaser]

i see some instability over the country tomorrow, east and west of the south island mainly, moisture looks very dry though around Christchurch city going by BSCH models so unsure if anything will happen.
Winds aloft at 500mb isnt favourable either, 15 knt westerly.

[spwill]

Some towering Cu showers drifting onto the Auckland area from the east today but they missed my area, only a couple of light showers here.

[Chris Raine]

Flew over the Alps at 5.30pm Weaved between Cb's between Hokitika and Chch.We were at 25000 ft and Cb tops another 10000 ft higher

[NZstorm]

The heavy shower risk has cleared from Auckland but will be back Thursday by the looks. But weekend will be fine.

[Manukau heads obs]

the showers yesterday were due in part to wind convergence..where the easterly flow around the high was slowly done moving across the NI and into the tasman (isobars further apart), as well as due to a bit vorticity from the jet stream to the north (which has dragged alot of moisture from the remains of the cyclone across in the upper levels) and also from that cut off upper low over the SI
all that should still exist today...to a degree..so just need some sea breeze convergence as another trigger

[NZstorm]

Both ukmet and gfs are showing warming around 700mb, hence my reason for no heavy showers today.

[Manukau heads obs]

there is some patchy rain around from some mid deck cloud currently out to my NW and over the coro
to me the sky still looks unstable enough
if we get a sea breeze convergence develop

time will tell

[Manukau heads obs]

M/S thunderstorm outlook update agrees with you NZstorm

[matttbs]

I'm very surprised at how quick and active this TS has developed. A lot of thunder, heavy rain and a few flashes. Now it's pissing down! Can see some rotation also. Just sitting on top of my place, not even moving

[Dean.]

Rumbles of thunder from a storm developing west/southwest of town here

Weakened as it moved east

[Manukau heads obs]

looking like models getting in agreement for some rain from the north next week

[NZ Thunderstorm Soc]

Has been interesting looking towards TC from about 3:30pm.
Uplifts and possible CB formations, although weak.

I believe Aaron took a nice photo of it, must post it up

[Thunder]

Took this photo from near me, looked better a little earlier on and seemed to be a good amount of scferics on the radio. Not much lightning seen though but did see a couple of flashes in the cloud.

[NZstorm]

Nice photo Aaron. The cloud looks moisture starved.

[spwill]

I'm picking its weakening as it has come off the foothills, good photography as always from Aaron.

[Thunder]

Yeah, it definitely weakened as it came off the foothills. Started out over Mt Peel, as usual. I was coming home from going to Ashburton so raced back to get my camera, should've had it with me, doh! So could've got a better pic but oh well.. Thanks anyway

[NZstorm]

An unstable upper trough crossing the North Island Friday but unfortunately the surface winds are SW which pushes any convergence out to the east. (Bay of Plenty).

[spwill]

It has been the least humid Summer I can remember in Auckland, very few muggy nights. Very little in the way of sub tropical troughing making it this far south this year.

[Manukau heads obs]

I notice that the El Nino Index has gone back to zero....
certainly there is no warmer than normal water where it traditionally is in the pacific for an el nino to be supported anymore
(the NW pacific is much warmer than normal though, which is part and parcel of the unusual weather patterns over the USA currently)

Towering Cu in our skies, 24C, dp around 16C
