General January Weather

[Richard]

Huge range in rainfall this month from my end of the Amuri plains to the northern end, Waiau has had only .2 mm, 43mm here.

[NZstorm]

Signs of a hotter airmass next week. This summer has lacked the heat bubbles crossing the Tasman from Australia. February may see a change.

850mb Chart for next Tuesday.

Noticed that yesterday on GFS, La Nina really keeping those NW flows away until the PV threw a wobbly this week. 30C+ possible for eastern areas.

[Awhituobs]

looks like a big pattern change back to more la nina type pattern for February

Anyone ever seen a rainbow like this. Not defined and really low. Taken this arvo at kuratau on the SW corner of lake Taupo looking back north east toward the SH1 side. Really bizarre rainbow. IMG_3028.jpg

Nice capture! Fairly certain it's a form of 'Circumhorizontal Arc', rather than a 'rainbow'.

Thanks Nev. It could have been one of those. It was there for 20 minutes. Quite remarkable and caught the attention of many onlookers.

After a rather cool night, down to 5C, it was a day of northerly winds and high cloud more extensive late this afternoon.
Today's maximum was 20C.

Nice pic! It's a rainbow but only the top of the arc is above the horizon because of a high sun elevation behind you. The lower the sun, the more a rainbow shows above the horizon.

The sun was lowish. It was 5pm these pics were taken.

maybe it was from the light reflecting off the lake?

[Cyclone Tracy]

2 cents worth.

It's safe to say now, that the late final warming (14th Dec) of the Stratospheric polar vortex has trumped any significant La Nina influence on December and January for NZ. Noted for future years. The polar flush out is almost done. MJO and a tropical standing wave enter the playing arena in February. Should be a warm and humid February ahead with plenty of tropical cyclogeneses above NZ.

February is usually a warm month anyway with lots of 30 plus temperatures.
Interesting day here cloud wise but nothing really happening apart from the odd shower this morning and a few spits this afternoon.
Mild temperatures with it getting up to 19.1C.

[Richard]

Got 10.4mm yesterday bringing it up to 35mm from the resent system, 57.8mm for the month

[NZstorm]

EU has 36C in mid Canterbury on Tuesday and 34C in Gisborne on Wednesday. The heat bubble originates from western Australia.

[cbm]

A few days of showers have crept total to 46mm for the month. Oh well, better than last January's 5.6mm for the whole month.

Nice to have a reasonably calm, very sunny day in Chch today. Looking forward to seeing what temperatures we manage to get up to midweek.

[darcyplumb]

Appears to be some showers developing in the Mt Peel area. Moderate easterly blowing in Ashburton at the moment with moody skies overhead.

[NZ Thunderstorm Soc]

A mainly fine day but with some interesting cloud around. Easterly winds.
Today's maximum was 23.1C.

Article in thee local rag about the thunderstorms we had here on Jan 2nd.

[Cyclone Tracy]

While the ocean still shows a La Nina signature, GFS today is showing the atmospheric La Nina signature is kaput, gone....just like that and its takes 2 to tango. It's now up to a strong MJO pulse and tropical standing wave to try and produce subtropical rain makers in the short to medium term but the ridge is the arch enemy.

[jamie]

Looking like 3 summers in a row with a stubborn atmosphere that shuts off the tropics.

So far not the Summer I thought we might have.
Easterlies developing later next week, time will tell whether much in the way of rain can reach here from the north in February.

[mikestormchaser]

Tuesday showing mid 30s in Canterbury infact eastern north and south island looks warm. Wednesday aswel. before cooling off thursday

I see we've had 15mm in our hood while we were away since new years. So a quarter of yours

[jamie]

The clouds today have been amazing in Taupo. Hundreds (literally) of lenticular clouds forming on the Lee ward side of the central plateau
