General March Weather

[melja]

34 in Rangiora at the moment and 32 in the house, bloody horrible.

[Razor]

Having a quick look at the long term records Razor I can;t even find 2 days in a row over 30C let alone 3 - remarkable!

There have been a few Marches where Chch Aero has recorded 2 consecutive days of 30C or more:

31.9C & 31.2C on Mar 10-11, 1990
30.7C & 31.4C on Mar 23-24, 1983
33.3C & 32.8C on Mar 03-04, 1968
31.3C & 30.4C on Mar 09-10, 1959

Looks like ChCh Aero has now crossed the 30 mark for the third day running. EDIT that- I think ChCh Aero got 29.7 on Saturday if The Press is correct.

The years above interest me too 1983 was during an el nino event. 1959 was a mild El Nino event. 1968- this was a month before Cyclone Giselle and the Wahine disaster (tail end of a La Nina?). 1990 tail end of La Nina?

The gfs tends to overcook the instability numbers in the warm air mass/high humidity set ups.

But there will be some instability with localised downpours associated with the rain event on Thursday.

Rupert Wood would know

[Razor]

30 looks on the cards again today.....

UPDATE 1:10pm 30.2 degrees in our hood, 4th consecutive day nailed
I have a friend in Rarotonga this week who has seen nothing but rain and temps in the 20's lol

[melja]

Oh but so much more humid, shame to go to the islands and have rain tho. Im of to Niue again in May so hopefully no rain like it was in November, got tickets $258 return so bargain of the century.

[Richard]

Coldest morning for 5 days with 10deg.

Hoping for something interesting with tomorrow's front

[moylanr]

Brief but real intense rain in Harewood, roads dry in Hornby.

Aircraft taking different flight paths.

Faint Rainbow in photo looking east from Hornby

[Richard]

Looking very stormy to the south now

[Razor]

That was explosive development through here that is for sure!

[melja]

Why are we on 2 topic's now, thought it was related to storms one.

[NZ Thunderstorm Soc]

Good photos there Richard.
Why is the photo upside down, in your posting, Moylanr?
Bob Crowder rang me up to say that he heard a few rumbles of thunder this afternoon, just north of his place
I saw the cloud forming on what looked to a bit of a gusto front, on the way home from work. I stopped an watched development, but I didn't think it would of developed into anything but it did, probably because of the moist conditions ahead of it. The wind had been light SW for much of the day, especially when all the low cloud and clagg cleared away.

Good photos Richard, there was a good convergent southerly into very moist air.

[NZstorm]

Interesting to see the colder upper air across the country in the coming days. Could be some hail in Waitomo tomorrow as a strong shortwave crosses. Can't say I have seen an upper level pattern like thiat in a while.

[Richard]

Good photos Richard, there was a good convergent southerly into very moist air.

Problem was, as is often the case here was the NW wind pushed it east, storms from the S or SW are rare here

They drift east in the upper flow, you want low level onshore flow for moisture.

Tomorrow (Sunday) is a repeat of today at another coldish 500mb trough crossing the North Island.
Seems to be a lack of convergence though tomorrow.
Hawkes Bay and Coromandal Peninsula could see a storm.

[NZ Thunderstorm Soc]

A weak Cb form through the haze probably around the Oxford area>?
Slight blob on the Rakaia radar for up there.
Nothing really to get excited about but as the weather here as been so boring here, of recent months, anything like this makes me smile and worth a mention.

A bit of colder upper air across the South Island today which is a sure sign of Autumn.

The shortwave trough crossing the North Island today was about 6 hours too early. You want them timed for late afternoon rather than late morning.

Another fine day for Auckland with temps into the mid 20's.

[jamie]

We had a bright morning this morning. Now fog has descended on us from the west. Thick too. We seem to have had a lot of fog this March.

[Captain Salty]

Humid air for chch this morning. Certainly notice it when running.

[Richard]

A lovely afternoon with a moderate NW wind which started about 11.00am, high of 23.7 at 1.02pm

[NZ Thunderstorm Soc]

An autumnal morning this morning driving to work with a low sun in the sky.
Light NE here all day, with a pleasant tempeaire.

[melja]

Thick fog round lake Benmore till after 12pm today but then a lovely NW day.

[spwill]

Good Easter weather for Auckland, enjoying the last of the Summer weather.
