Stuck at only 18C approaching the warmest part of the day, despite full sun almost constantly since dawn. Doubt will reach the forecasted 21C. Really is a prolonged cool spell this one.

A welcome 4mm of rain here earlier this morning. GFS showing rising dew point temperatures next week and the chance for some decent rain later in the week, something to watch in the models for a change.

Definitely a shift in the weather pattern next week, with a more N-NW flow directed over the country.
The rain being fed down from the tropics and developing mid Tasman low, will change the temperatures too.
Warmer day time temperatures and overnight lows.
In particular Wednesday is quite warm in the upper levels and certainly for April, so depending on high cloud cover you could be looking at surface temperatures around 26 or 27C.
Then abit of welcome rain and cool off in the east from Thursday, any snow will be quite high up I'd imagine.

We could be looking at some fairly sizable alpine and foothills rain totals later this week Canterbury, Otago, Southland. Worth keeping an eye on.

Hopefully not a southerly storm about Cook Strait overnight 12th/13th, when I'll be crossing on the ferry.

Some snow for the higher parts of the South Island high country later Thursday into Friday.

A period of heavy rain for Auckland later Thursday or Friday morning. Starts turning humid in Auckland from tomorrow.

Well called, 26.3 on MS at Christchurch airport at the moment. Lovely for mid april.

Edit - Make that 27c

Nice to have the warmer weather.
Some thunderstorm risk for the upper North Island Friday..

Thursday night, Friday forecast looks wet and windy.

A heavy shower risk for Auckland tomorrow morning. Looks like the front will be east of here by 9am with Coromandel and BOP in the firing line.

See if we can catch a downpour with the front tomorrow morning. Looks like a mainly fine day here after the front. I would like 20-30mm for the garden.

It was 22 degrees at midnight in Halswell last night. Bottomed out at 19 around dawn

Have picked up 17mm here. Nothing noteworthy unfortunately…

It was very warm during the night. I was working on a power outage in Henry Rose Place, Albany and the temperature was 21 degrees C at 02.00 hours.

18mm here. The main weather feature of the last 24hrs was the strong wind yesterday.

Local power outage here for about 2-3 hours today. 20mm here overnight and this morning... blue skies now.

Bit more in Northland with around 100mm at Kaikohe and over 70mm for Kerikeri and Kaitaia.

Travelling up from Christchurch to Tūrangi yesterday and today and pretty wet much of the way. Downpours in Wellington around dawn as I got off the overnight ferry, and showers further north to Tūrangi. Heavy squally rain about the northern part of the Desert Road, with the temperature at 9C at the summit.

This tweet from NIWA (graphic copied), which was posted late morning on Saturday, mentions that parts of Wellington had a wet day on Friday. Unfortunately, it does not list how much fell in the city or at the airport - METARS suggest it rained all day.

Rainfall figures are for the 24 hours to 9am on Saturday (13th April).

Kelburn with 48.6mm, temperature 11.4C-20.7C. It has been an active weather week for NZ. Looking mostly settled for NZ with plenty of sunshine through to Thursday, any showers look mostly isolated. Another wet weather system from Friday next week.

Kelburn recorded 56.0mm and Wellington Aero 60.9mm in the 24 hrs to 9am on Saturday 13th. These were their wettest days since recording their second ever wettest days of 127.2mm and 116.1mm respectively on Feb 12, 2022 (only 152.4mm in Dec 1939 and 149.4mm in Aug 1971 respectively were wetter).

Below is MetService's 7 day cumulative rainfall map to midnight last night. Note that their scale only goes up to 200mm, whereas parts of Westland recorded up to 5 times that.

First 2 weeks of April running 0.4C above March locally (due to warmer nights).

Friday was an interesting one in Wellington, with the rain radar showing the rain bands moving from the NNW all day. The southerly change arrived at the airport just before 10am, and listening in to airport Air Traffic Control (ATC), the boundary from Northerly to Southerly was evident for about 2 hours afterwards. ATC were checking in with each plane as it landed to get an update on when they encountered the wind sheer. Initially caught out a number of flights as it was down at 200ft and planes were coming in to land to the south with a 20-knot tail wind, then hitting the sheer layer just to the north of the airport and then landing into a 15-knot southerly. Multiple go arounds, but all managed to land ok on 2nd attempts. The boundary layer eventually moved to above 2000ft, and stopped causing any issues, but the rainfall continued till around 7pm. The southerly did not get much over 15-20knots though the whole day,

The rain was awesome for the garden though, and really needed. We have lost a couple of 4-5m tall trees in the reserve outside our place due to the lack of rain, combined with the regular gales this summer. Also off the back of 9 out of 10 months where rainfall has been below the historical average, it certainly has been noticeably dry!

Ranges to the west have been sheltering Taupo area over the last 2 days, but some light showers affected Ruapehu today. Was about 7C at base of Whakapapa ski field, and fresh recent snow visible up the top of the mountain. (Only above about 2500m)
