General April Weather

Patchy rain arriving here now for a warm damp start to April.

The pattern ahead looks more westerly than we have seen so far this year, so a better chance of a cool/cold air reaching NZ at times next week or two.

I see they have issued a severe thunderstorm watch for those areas, valid until midday Saturday.

The last two weather systems which were forcasted to deliver around 15-20mm each have come to nothing (apart from Tony who was pretty much spot on). One thing ive learnt about droughts in Canterbury is you know you are in severe drought when rain that is forcasted never arrives, but then there is only two sides to Canterbury weather, wet- or dry,when ya in wet faze it rains flat out when rain is not forecasted.

Yes.

Tomorrow's front could prove useless, here.
When it's mentioned in the forecast, ' a few showers' usually means a dry southerly change, as far as I'm concerned, especially with this current weather scenario..
It would be nice if we got a decent thunderstorm, with a southerly change, but this El Nino has been pretty useless as far as that goes, so bring on La Nina

We need a big upper level system with colder upper air. Models have been playing around with such a system for mid month. Hopefully it comes off.

Looks like a storm or two/possible hail for the Bay of Plenty tomorrow with that S change.

Today is even warmer still, max of 25.3 here so far. May get a new April record for my station today (current record is 25.4)

The southerly gone through. Still waiting for those "Few showers"

A bit of mama on the approaching Sly change

Neat photo Jamie

Yet another dry weather system for here, the 9 -10mm forcasted came to zip

Models have been pointing to a cold system to affect NZ next week, may or may not eventuate but interesting to see it in the modelling.

southerly change here now..has fizzled up the showers that were off the coast here...

Got a great display of lightning over East Cape from here. It's incredible how bright it is from here.

NZstorm · Unread post by **NZstorm** » Mon 04/04/2016 19:32

A lot of lightning over the eastern Bay of Plenty this afternoon/evening.

GFS had been indicating thunderstorm development in that area due to SE change/left over moisture and upper level divergence within exit region of jet.
500mb temps also cold at -18C.

Useful 6mm yesterday, ground frost right now with 1.9C

A fresher feel to Auckland weather next few days with the humid weather gone.

David · Unread post by **David** » Tue 05/04/2016 18:41

Some quite big puffy cumulus to the E/SE this evening, and some heavy showers showing on the radar. Caused by the SW/SE convergence maybe?

spwill · Unread post by **spwill** » Tue 05/04/2016 18:56

Yes, a nice convergence line out there, upper level temperatures are rather cold today.
Autumnal for Auckland next couple of days.

Coolish this morning with a low of 6, but a nice and clear morning.

spwill · Unread post by **spwill** » Wed 06/04/2016 11:12

Coolest morning of the year for Auckland, down to 10C.

METVUW is showing a nice funnel cloud taken from Hamilton yesterday. I'm not surprised there was a funnel. It was that sort of afternoon where you kept an eye out for something like that. We did have some nice afternoon convection going on.

Pleasant breezy sunny day here, a large rainbow halo around the sun, and some interesting lines and curls of high clouds.

Yes, that is a nice funnel pic in the Met View site. http://www.metvuw.com/
April tends to be a good month for funnels when we start getting the colder air masses.
The cloud tops 4km.
