General April Weather

[spwill]

The dewpoint around 14C this week in Auckland so a little bit of humidity in the air for a milder feel to our weather.

Average to above temps across NZ this week generally so a different weather week to last week.

[Bradley]

Both GFS and ACCESS going for a strong cold from next Tuesday, a little unusual for both models to be in agreement 8 days out!

[NZstorm]

definitely looks like showers for the upper half of the North Island Thursday with 700mb temps plunging to -3C. Could even be another landspout around any surface boundaries that develop.

That waterspout in the big smoke looked impressive, and sounds like your guys up north got a fair bit of rain too. I was wondering what the soil moisture deficit in the Waikato is now?
Got 19.4mm in the last 24 hours to now which is a lot more than I was expecting. Today's high was only 10.1C

[Manukau heads obs]

since it was over land, it was a landspout
who ever first called it a waterspout was mistaken
also I would hardly call a rural dairy service town of 8000 the big smoke

[spwill]

More unstable wet weather heading for NZ next week, the cold upper level systems are coming onto northern NZ now, seasons changed.

I read that it was in auckland? So if not where was it?

The Auckland region which has a lot of rural.

Ok to be more specific I read that it was on the manukau harbour by the airport, sure one side is city and the other side is clarkes beach but Jesus it's close enough, no need for the smart ass bloody attitudes. I know auckland has a lot of rural, I lived there for 5 years.

How can that map show areas like Gisborne with soil moisture deficit similar to areas in North Canterbury when much of the Gisborne district had over 70-80mm of rain in the third week of March

[Manukau heads obs]

Ok to be more specific I read that it was on the manukau harbour by the airport,

People in the city/airport region thought it was over the harbour
but it was in fact well in land, south of Waiuku

Code: Select all

 no need for the smart ass bloody attitudes

not tring to be a smart ass, but just surprised about the bad info that got out there about it, thats all, and so just trying to correct that

[shovelopikis]

rolling thunder last few hours here, and a few flashes north to tokoroa direction, had dark ominous clouds all afternoon, but very still and calm

[Manukau heads obs]

I did notice showers in that area on the rain radar
are they upper level CB's?

must have been, good show though, lasted for a few hours

[spwill]

Some weak afternoon showers here today, cloudy conditions today with little or no wind here.
Max 21C, dewpoint 15C

[NZstorm]

Looking like some good lightning activity on the way for the South Island West Coast/Alps Sunday/Monday time frame, spill over lightning possible Monday.

North Island likely to get some thunder activity as well. A major upper level system Monday!

[melja]

Oh good i will be in the mackenzie country this weekend so will catch some good spill over storms i hope.

Looking like spill over chances are on Monday and for the upper half of South Island. But that's just my assessment, I could be wrong.

[NZstorm]

850mb winds for midday Monday. They suggest there could be isolated severe squalls down the west of the North Island also upper South Island with the front if instability is sufficient. When the airmass is unstable the cb can bring the strong wind aloft down to the surface. Taranaki looking to have the best exposure to this.

Models suggesting the front is forecast to come post the mid to upper level jet, however the remnants will still be there.

[melja]

Nothing much to report in the mackenzie country just high cloud warm and calm most of the time.

[NZstorm]

The upper level system that gave Sydney severe hail yesterday will be coming into the west of NZ tomorrow afternoon, but the air mass will of coarse be modified and not so unstable.
Upper South Island to Northland/Bay of Plenty will have a marginal squall risk. Also a small possibility of a tornado.

Lovely weather today. I see the Northerlies are forecast to gust up to 55 knots (100 km/h) in the Hauraki gulf tomorrow. An indoors day

latest met service thunderstorm outlook ramped up
