Heavy rain about central NZ tomorrow

Looks like some heavy rain tomorrow, probably affecting the areas hit by the big February event. Similar scenario, with colder southerly change meeting a trough/low to the north, though I doubt that it'll be anything like February. Though it does look like a cold change, the coldness will probably be in the form of low maximum temperatures under the cloud and rain, rather than a low freezing level, unlike the wintry blast earlier in the month.

Some unforecast drizzle today in Chch

, but fine by evening. Should be wet by tomorrow morning though.

its great to watch 2 different airmasses like this collide!
already there are things happening in the central tasman, heading towards the western NI...good, need some more rain still here...things have greened up lots though, and i was pleased to see the tv1 weather girl say there were happy farmers around with the rain that fell!

I think Isolated heavy showers/thunderstorms/hail over the North island this afternoon from Manuwatu northward.

Fine morning here with 15C (6.45am).

Not so bad in Chch this morning - a bit of light rain and a cold southerly freshening a little, but not as bad as was predicted yesterday. seems like the front is moving north a bit quicker than first thought. Still could be plenty of action up north should different systems collide.

You could see crisp Cu's forming this morning over parts of Akl

Yes, some Towering Cu have popped up around Auckland over the past 40 minutes.

Currently in Central Auckland it's 19c with a dewpoint of 16c.

Well the weather is crap down here in Omarama today. Cool, but not cold; drizzle but no real rain; murky grey cloud, without snow...it's like Auckland without the traffic or John Banks...BAH! Keep it up there please!

Have a line of strong Towering Cu + Cb through our southern skies now

Manukau heads obs · Wed 28/04/2004 13:57

Heh, the guy changes his stories faster than the Auckland weather.

Auckland has John Banks while Otago has Shrek the Sheep.

Have more Cu building to our South and new Cb forming. Todays convection has been summer like.

Only some very light showers this morning, and a partial clearance (to just partly cloudy) this afternoon. Cold though - they got that one right.

Manukau heads obs · Wed 28/04/2004 17:44

In the 14 hours between 4pm today (Wednesday) and 6am Thursday
morning, up to 75mm of rain could fall in some places, especially
east of Te Puke. Rainfall rates are likely to be rather variable,and
could reach 15-25mm/hr at times. Further showers are expected on
Thursday, some of which may be heavy.

Great to see some unstable conditions... it's been a few months!

There were quite a few towers going up during the drive home, most of them fell apart pretty quickly. Way off to the north there were some very high tops that looked good... couldn't get a picture of them from the motorway as the traffic was flowing for a change.

1pm Auckland CBD

5:20pm looking south towards Auckland

5:39 looking south towards Auckland

those ones to the north showed up well on the rain radar, they were around dargaville

NZstorm · Unread post by **NZstorm** » Wed 28/04/2004 20:34

BOP had some decent rain last night with 93mm recorded at Tuaranga.

The cb development around Auckland today looked fairly minor with the T/cu were glaciating out around the 6000m level.

Afternoon heat shower just south of Manukau City.

T/cu were building upto about 6000m then glaciating.

Very heavy rain in the showers. Sperics observed.

Manukau heads obs · Wed 28/04/2004 20:42

neat photos guys!
some observations i made:
the showers developed very fast
the upper level movement was a big haphazard, and at times was tending to want to build against the surface easterly
this made the movement of the showers hard to predict....they tended to die quickly once they moved from the growing area....
(they went all around us here all afternoon!!)

The cloud build ups this afternoon may not have got up to any great height but still looked spectacular from here in MtEden. Great photos guys.

Another overnight deluge in the Bay of Plenty with 73mm at Tauranga.
Thats on top of 93mm day before. Some quite active looking cb affecting that area. Plenty of spherics on am band this morning.

I think there is a higher chance of a thunderstorm or two forming in the Auckland vicinity today than yesterday. Upper air looks a bit colder this morning.

6.45am Currently partly cloudy, calm, 14C.

Manukau heads obs · Thu 29/04/2004 07:32

the BOP was really dry, now its drought to flood!
there is a big shower just to the north of me here now....somewhere over the waitaks...

C-Nimbus · Unread post by **C-Nimbus** » Thu 29/04/2004 08:21

I agree with NZStorm, should be greater potential today.

well lets hope anyway, after all it is the 'weather' that we are trying to predict here!!!

spwill · Unread post by **spwill** » Thu 29/04/2004 10:36

Have just had a Lightning Flash and Thunder over Central Auckland.

We have had light to moderate rain here since about 8am and now it's turning alot darker outside and the rain is getting heavier
